Silverado HD Strong Arms the Competition

DETROIT – How tough are heavy-duty trucks? A recent frame-twisting test found that the use of roll-formed steel in its bed allowed the tailgate of the 2015 Silverado 2500HD pickup to be lowered on uneven terrain while greater twisting of one competitor’s frame kept its tailgate from being lowered.

AMCI Testing, a third-party research firm hired by Chevrolet, recently subjected the 2015 Silverado 2500HD and a Ford F-250 Super Duty to a rigorous frame twist test, in which the truck was driven onto two staggered ramps, where the wheels on one side of the truck hit the ramp before the other, placing a large amount of torque on the frame. Measurements were then taken for the distance of displacement of the cab body and the bed, determining the amount of twist to which the frame is subjected.

AMCI found that during the test, the Silverado HD’s frame allowed 0.26 inches of twist, while the F-250 Super Duty allowed 0.94 inches of twist, 262 percent more than the Silverado. The twist was so great on the Ford that when under stress, the tailgate could not able to be lowered, while the Silverado’s available EZ-Lift and Lower Tailgate operated normally. You can see the test here.

“The use of high-strength steel in the Silverado HD is what allows the Silverado to handle even the toughest of jobs,” said Jeff Luke, General Motors’ executive chief engineer for full-size trucks. “Paired with a fully boxed frame, high-strength steel is what makes the Silverado come from the family of the most dependable, longest-lasting full-size pickups on the road.”

Roll-formed steel in the Silverado HD vs. the stamped steel bed of most competitors involves using a higher-grade steel that’s stronger, lighter and more durable. The fully boxed frame provides a rigid foundation.

The Silverado’s body is also constructed using similar high-strength steel. Approximately 67 percent of the cab is constructed with high-strength and ultra-high-strength steels. They’re used in the A-pillars, B-pillars, rockers and roof rails, as well strategic sections on the interior structure.

Ultra-high-strength steel is used in areas of the rocker panels and underbody to help improve crash performance. The Silverado uses more high-strength and ultrahigh-strength steel than any competitor’s full-size pickup truck, according to market research firm Ducker Worldwide.

America’s Favorite Performance Car Line Expands in 2015

Chevrolet's 14 performance car models ranging from 323 to 625 horsepower.

NEW YORK – With the introduction of the 2015 Corvette Z06 Convertible, Chevrolet offers enthusiasts 14 distinct performance-car models – including nine Camaro models, the SS performance sedan and four Corvette models. Output ranges from 323 to an estimated 625 horsepower.

“Chevrolet has been America’s best-selling performance brand for four consecutive years, due in part to the breadth of our lineup,” said Mark Reuss, executive vice president, Global Product Development. “For 2015, we will have the best range in our history, offering a performance car for virtually every enthusiast, from the 30-mpg Camaro LS and the COPO Camaro drag car to the 625-horsepower Corvette Z06 Convertible supercar.”

The 2015 Chevrolet lineup of performance cars includes:

Corvette

The all-new Corvette Stingray was the most awarded vehicle of 2013. Built on a new aluminum chassis and featuring a new 6.2L V-8 rated at 455 horsepower, it backs its performance capability with the greatest efficiency of any sports car with at least 450 horsepower: an EPA-estimated 17 mpg city driving and 29 mpg on the highway with its seven-speed manual transmission. A new eight-speed paddle-shift automatic transmission will be offered in 2015.

The new Z06 Coupe and Convertible join the lineup for 2015. The new Z06 delivers supercar levels of performance and technology, including at least 625 horsepower and 635 lb-ft of torque from an all-new supercharged engine, and true aerodynamic downforce for high-speed stability. The Z06 Coupe is the most capable Corvette in the brand’s history, recording the fastest lap of any production car ever tested at GM’s Milford Road Course test track. The Z06 Convertible will be one of the most capable convertibles on the market – matching the coupe model – with 0-60 acceleration in less than 3.5 seconds.

Chevrolet SS

Chevrolet’s first V-8-powered, rear-drive performance sedan since 1996 is based on a race-proven, global platform that underpins the Camaro, and, in Australia, the high-performance Holden VF Commodore. Lightweight aluminum hood and deck lid panels contribute to a nearly 50/50 weight balance, while the performance of the SS’s 415-hp / 415-lb-ft 6.2L V-8 enables 0 to 60 mph sprints in 5 seconds flat.

Camaro

The Camaro lineup starts with the 323-horsepower V-6-powered coupe and convertible, which match performance with efficiency – including up to 30 mpg on the highway for the 2LS coupe model – and a suggested starting price of $23,555 not including tax, title and dealership fees.

The SS coupe and convertible come with Chevy’s legendary small-block V-8, featuring a 6.2L engine delivering up to 426 horsepower, and 0-60 acceleration in 4.5 seconds.

The Camaro 1LE is the most affordable, track-capable Camaro in the lineup, starting at $37,350. Offered only on SS coupes with a manual transmission and optimized for the track with unique gearing, suspension tuning and tires that make it capable of more than 1 g in cornering grip.

The Camaro ZL1 (coupe and convertible) is equally at home on the race track, the drag strip or daily commuting. It features a supercharged 6.2L V-8 with 580 horsepower and 556 lb-ft of torque – making the ZL1 the most powerful Camaro ever from Chevrolet. It is also the most technologically advanced, with standard Magnetic Ride Control and, on coupe models, Performance Traction Management.

The COPO Camaro, limited to 69 units this year, is a hand-built race car designed exclusively for drag racing – the first purpose-built Camaro race car from Chevy and the quickest Camaro ever from the factory

Finally, the all-new Camaro Z/28 returns the iconic model to its road-racing roots. It features exterior elements designed like a race car to produce downforce that presses the car against the track for greater grip – up to 1.08 g in cornering acceleration – and faster lap times. Camaro Z/28 logged a 7:37 lap on Germany’s legendary Nürburgring track, which was faster than published times for Porsche 911 Carrera S and Lamborghini Murcielago LP640.

Drop-top Supercar: 2015 Corvette Z06 Convertible

2015 Chevrolet Corvette Z06

DETROIT – Chevrolet today introduced one of the most capable drop-tops on the market: the 2015 Corvette Z06 Convertible. With at least 625 horsepower, and 635 pound-feet of torque, the Z06 is also the most powerful convertible ever produced by Chevrolet.

“The Z06 Convertible is a world-class supercar in every sense,” said Mark Reuss, executive vice president, Global Product Development. “Only a handful of convertibles in the world bring more than 600 horsepower and 600 pound-feet of torque. Even fewer can match the advanced technologies, aerodynamic design, and visceral driving experience of the Z06 Convertible.”

This is the first   Z06 Convertible offered from the factory since 1963 when the Z06 option package was introduced for endurance racing. Records show only 199 Corvette orders with a Z06 package that year, including one convertible.

Recent technological advancements enable the building of a modern Z06 Convertible, said Corvette chief engineer Tadge Juechter.

“Until recently it was not possible to create a lightweight, open-roof structure strong enough to cope with the braking, cornering, and acceleration of Corvette’s top performance models,” Juechter said. “The frame for the Z06 convertible leverages advancements in computer-aided engineering, metallurgy, and manufacturing techniques – many of which were not available just five years ago.”

The aluminum structure is 20 percent stiffer than the previous, fixed-roof Z06. As there are no structural reinforcements needed for the Z06 Convertible, its curb weight is nearly identical to the Z06 Coupe. They also share the same chassis tuning, powertrain output, driver technologies and equipment options – including the Z07 Performance Package, which adds Brembo carbon-ceramic matrix brakes, Michelin Pilot Sport Cup tires and adjustable front- and rear-aerodynamic components.

“The most impressive aspect of the Z06 Convertible may be its performance bandwidth,” said Juechter. “Very few cars on the market can match its combination of extreme, supercar levels of performance; the flexibility for daily driving and long-distance commuting; and the 360-degree, open-air driving experience only true convertibles can offer.”

All-aluminum, high-tech foundation

The Corvette Z06 Convertible represents the culmination of more than four years developing an all-new, all-aluminum structure for the seventh generation Corvette. That structure, built at General Motors’ Bowling Green Assembly plant, was designed to the specifications of the Corvette Stingray, Corvette Z06 and the Corvette Racing C7.R.

“We wanted a frame that was lighter than the steel frame of the previous Corvette, yet strong enough for both a 600-horsepower convertible and a 24-hour endurance racer,” said Ed Moss, engineering group manager for Corvette structures. “That would not have been possible without improvements in computer-aided engineering software, which allowed us to model more than 17,000 frame iterations, with each iteration improving strength and stiffness, while reducing mass.”

The team used nearly 186,000 computational hours of modeling to develop the frame. It features main rails composed of five customized aluminum segments, including aluminum extrusions at each end, a center main rail section and hollow-cast nodes at the suspension interface points. The gauge of each segment varies in thickness from 2mm to 11mm, tailored – along with the shape – to meet the strength and stiffness requirements for each frame section with minimal weight.

These components are assembled using many advanced manufacturing processes, including:

  • 439 spot-welds using a GM-patented process that uses a unique electrode designed specifically for aluminum
  • 188 Flowdrill-machined fasteners installed by a high-speed drill that extrudes the frame material to create a strong, integral collar tapped for bolt-on fasteners
  • 113 feet of structural adhesives used in conjunction with welding and fasteners to increase overall frame stiffness
  • 37 feet of laser welds, which join frame sections via a precise beam of high energy that minimizes heat beyond the weld area for improved structural accuracy.

The only structural differences between the Z06 Coupe and Convertible are provisions for mounting the power-folding top, and repositioned safety-belt mounts.

High-performance aerodynamics

Like the structure, only minor design changes distinguish the Z06 Coupe from the Convertible. The Z06 convertible features an electronic top that can be lowered remotely using the car’s key fob. The top can also open or close on the go, at speeds of up to 30 mph (50 km/h).

With the top up, the Z06 Convertible is designed for a refined driving experience. A thick fabric top, offered in four colors along with sound-absorbing padding and a glass rear window, contributes to a quiet cabin and premium appearance.

Behind the seat backs, dual accent panels – either Carbon Flash-painted or available with exposed carbon fiber – enhance the character lines of the tonneau cover. Corvette Stingray’s signature “waterfall” design originates in the valley between the nacelles, bringing the exterior color into the interior.

The power-operated tonneau cover necessitated moving the air intakes for the differential and transmission coolers from the rear quarter panels on the Z06 Coupe to the underbody of the Z06 Convertible.

Otherwise, both models share the same, performance-driven aesthetic.

“Practically every exterior panel serves a functional purpose to meet the performance goals of the Z06,” said Tom Peters, Corvette design director, “The flared fenders accommodate larger, wider wheels and tires for more grip. The larger vents provide more cooling air to the engine, brakes, transmission and differential for increased track capability. The more aggressive aerodynamic package generates true downforce for more cornering grip and high-speed stability.”

Both Z06 models are fitted with Michelin tires (Pilot Super Sport tires for the Z06; Sport Cup 2 tires with the Z07 package): P285/30ZR19 front, and 335/25ZR20 rear.

The tires are mounted on lightweight, spin-cast aluminum wheels (19 x 10 inches in front and 20 x 12 inches in the rear). Their open, ultralight design showcases the massive Brembo brakes, which contribute to the design:

  • The Z06 features two-piece steel rotors, measuring 14.6 x 1.3-inch (371 x 33 mm) front and 14.4 x 1-inch (365 x 25 mm) rear, with aluminum six-piston and four-piston fixed calipers, respectively
  • The Z07 package adds larger, 15.5 x 1.4-inch (394 x 36 mm) front and 15.3 x 1.3-inch (388 x 33 mm) carbon ceramic-matrix brake rotors for consistent performance lap after lap. They collectively save 23 pounds over the standard Z06 rotors.

Both Z06 coupe and convertible will be available with one of three, increasing levels of aerodynamic downforce:

  • The standard Z06 features a front splitter, spats around the front wheel openings, a unique carbon-fiber hood with a larger vent, and rear spoiler
  • An available carbon-fiber aero package delivers aerodynamic downforce four times greater than the standard Z06. It adds a carbon fiber front splitter with aviation-style winglets, carbon fiber rocker panels, and a larger rear spoiler with a fixed wickerbill – a small, vertical tab at the edge of the spoiler that significantly increases downforce. The package is available in black or a visible carbon-fiber finish
  • The available Z07 package adds larger winglets to the front splitter, along with an adjustable, see-through center section on the rear spoiler enabling customers to tailor the aerodynamics to their preference.

Compared to the Corvette Stingray, the Corvette Z06 fenders are 2.2 inches (56 mm) wider at the front, and 3.15 inches (80 mm) at the rear. Those extensions give the Corvette Z06 a wider, lower appearance further emphasized by a unique rear fascia. It incorporates the same taillamp assemblies as the Stingray, but on the Z06 the taillamps are pushed approximately three inches farther apart, toward to edges of the body.

The exterior design also reflects the increased cooling required for the new Corvette Z06. For example, the mesh pattern on the front fascia was designed to deliver the most possible airflow to the supercharger’s intercooler heat exchanger, so much that the mesh grill directs more air into the engine bay than if the grille was removed.

The unique grille also features dedicated brake-cooling intakes and wider grille outlets on the bottom serve as air diffusers. A larger hood vent allows air driven through the grille to exit through the hood rather than being forced under the car, which could create lift.

Standard front and rear brake-cooling ducts, including Z06-signature rear ducts integrated in front of the rear fender openings, are also part of the functional design changes.

The Z06 benefits from interior details designed for high-performance driving, first introduced on the Stingray, including a steel-reinforced grab bar on the center console for the passenger and soft-touch materials on the edge of the console, where the driver naturally braces during high-load cornering.

Like the Stingray, the Z06 comes with two seating choices: a GT seat, for all-around comfort, and a Competition Sport seat with more aggressive side bolstering, which provides greater support on the track. A magnesium frame structure for both seats provides greater rigidity and strength compared with steel frames.

Unprecedented attention to detail and build quality complements the Corvette Z06’s performance. All models feature a fully wrapped interior, with every surface covered by premium, soft-touch materials. Available materials, depending on the trim level, include Napa leather, aluminum, carbon fiber and micro-suede.

The interior also features a flat-bottom steering wheel with a carbon fiber center spoke. The Z06 comes in five interior colors, including two that are unique to Z06 – blue and dark gray.

Supercharged, efficient performance
The heart of the 2015 Corvette Z06 is the all-new LT4 6.2L supercharged V-8 engine, expected to deliver at least 625 horsepower (466 kW) and 635 lb-ft of torque (861 Nm). To balance performance and efficiency, the LT4 leverages the same trio of advanced technologies introduced on the Corvette Stingray: Direct injection, Active Fuel Management, or cylinder deactivation, and continuously variable valve timing.

These technologies – combined with the fuel-efficient multi-speed transmissions, aerodynamic design and lightweight construction – help make the new Z06 surprisingly fuel efficient.

“The supercharged LT4 engine delivers the greatest balance of performance and efficiency ever in the Corvette,” said John Rydzewski, assistant chief engineer for Small-Block engines. “It is one of the world’s only supercharged engines to incorporate cylinder deactivation technology, enabling it to cruise efficiently on the highway with reduced fuel consumption, but offer more than 600 horsepower whenever the driver calls up its tremendous power reserve.”

The supercharged LT4 comes with a standard seven-speed manual transmission with Active Rev Match, or an all-new 8L90 eight-speed paddle-shift automatic transmission designed to enhance performance and efficiency. The seven-speed manual incorporates rev-matching technology for upshifts and downshifts. A new dual-mass flywheel and dual-disc clutch deliver greater shift quality and feel through lower inertia.

The eight-speed automatic is tuned for world-class shift-response times. Smaller steps between gears keep the LT4 within the sweet spot of the rpm band, making the most of the output of the supercharged engine for exhilarating performance and greater efficiency.

“There’s no trade-off in drivability with the new 8L90 eight-speed automatic transmission – it was designed to deliver performance on par with dual-clutch designs, but without sacrificing refinement,” said Bill Goodrich, assistant chief engineer for eight-speed automatic transmissions. “It is also the highest-capacity automatic transmission ever offered in a Chevrolet car.”

Featuring four gearsets and five clutches, creative packaging enables the GM-developed eight-speed automatic to fit the same space as the six-speed automatic used in the Corvette Stingray. Extensive use of aluminum and magnesium make it more than eight pounds (4 kg) lighter than the six-speed. Along with design features that reduce friction, the 8L90 is expected to contribute up to 5-percent greater efficiency, when compared with a six-speed automatic.

Track-proven technologies

The 2015 Corvette Z06 Coupe and Convertible leverage the technologies introduced on the Corvette Stingray, with unique features and calibrations tailored for its capabilities.

“Our mission with the seventh-generation Corvette was to make the performance levels more accessible, enabling drivers to exploit every pound-foot of torque, every ‘g’ of grip and every pound of downforce,” said Juechter. “It’s a philosophy we introduced with the 460-horsepower Corvette Stingray – and one that’s even more relevant with an estimated 625 horsepower at your beck and call.”

The new Z06 retains the SLA-type front and rear suspension design of the Corvette Stingray but uniquely calibrated for the higher performance threshold. The third-generation Magnetic Selective Ride Control dampers, adjustable for touring comfort or maximum track performance via the standard Driver Mode Selector, are standard on Z06.

Like the Stingray, the Driver Mode Selector tailors up to a dozen features of the Z06 to suit the driver’s environment, including:

  • Launch control: Available in Track mode for manual and automatic transmissions, providing maximum off-the-line acceleration
  • Traction control: Weather mode tailors traction control and engine torque for driving in inclement conditions
  • Performance Traction Management: Available in Track mode and offers five settings of torque reduction and brake intervention for track driving
  • Electronic Limited Slip Differential: Adjusts the rate at which the limited slip engages, balancing steering response and stability in different driving conditions with more aggressive performance in Sport and Track modes.

The smart electronic limited-slip differential, or eLSD, is standard. It features a hydraulically actuated clutch capable of infinitely varying clutch engagement. The system enhances all aspects of performance by constantly tailoring the clutch-pack engagement based on a unique algorithm that factors in vehicle speed, steering input and throttle position to improve steering feel, handling balance and traction.

Stingray Named One of Ward’s 10 Best Interiors

2014 Chevrolet Corvette Stingray

DETROIT – The inside of the 2014 Chevrolet Stingray is one of Ward’s 10 Best Interiors.

The yearly award considers all cars that are either all-new, or have had considerable interior refreshment for that model year. For 2014, the field was comprised of 41 vehicles, and were judged against ergonomics, driver information, fit-and-finish, materials, value, safety, comfort, and design harmony.

“We went to great lengths to insure that this vehicle was worthy of the iconic Stingray name on the inside and out,” said Ken Parkinson, executive director of Global Chevrolet Design. “We selected authentic, premium materials, integrated connected and intuitive technologies, all while balancing craftsmanship and precision execution.”    

Ward’s called out the Stingray’s carbon-fiber trim, microfiber headliner and contrast stitching on the bucket seats, saying the features were highly competitive with more-expensive competitors in the segment.

Drew Winter, editor-in-chief of WardsAuto World magazine, also cited the Stingray’s track-focus as a main reason the car was honored. He pointed to the high-visibility reconfigurable digital graphics in the instrument cluster and central display communicate mission-critical information to the driver on and off the track.

Stingray engineers developed a steel-reinforced grab bar on the center console for the passenger and soft-touch materials on the edge of the console, where the driver naturally braces during high-load cornering, a direct result of engineers taking the car to the Milford Proving Ground during development.

Ward’s continued: A blend of hand craftsmanship and machined precision is intended to ensure the fit, finish and ambience of the cabin is first-rate. The leather-wrapped instrument panel, for example, features hand-selected and hand-stretched materials for better grain matching with stitching performed by robots that deliver perfect seams.

The award follows last year’s win by the Chevrolet Spark.

  • Standard remote keyless entry and available remote start.

Trax will be offered in LS, LT and LTZ trims. Pricing will be announced closer to the start of production.

A Chevy inside and out

With its signature dual-port grille, prominent bowtie emblem and swept headlamps, the Trax is immediately identifiable as a contemporary Chevrolet. Its grille design – with chrome accents – emulates other Chevrolets and provides a more cohesive appearance across the brand’s lineup of crossovers and small cars.

Available cues such as front fog lamps and simulated front and rear skid plates lend a sportier presence, while vertical tail lamps flank the tailgate, accenting taught body lines and pronounced wheel arches that give the Trax a confident stance.

The 10 exterior are: Brilliant Blue Metallic, Orange Rock Metallic, Satin Steel Metallic, White Pearl Tricoat, Black Granite Metallic, Summit White, Silver Ice Metallic, Ruby Red Metallic, Deep Espresso Metallic and Blaze Red.

Inside, Trax’s distinctive styling carries over to a dual-cockpit instrument panel.

With Chevrolet’s connected by OnStar 4G LTE connection, Trax provides an available Wi-Fi hotspot that allows passengers to connect multiple personal devices such as smartphones, laptops and tablets, to high-speed wireless Internet.

Turbocharged performance

Trax is powered by a power-dense Ecotec 1.4L turbocharged four-cylinder engine backed by an efficiency-enhancing six-speed automatic transmission. The engine is expected to be rated at an SAE-certified 138 horsepower (102 kW) and 148 lb-ft of torque (200 Nm) between 1,850 and 4,900 rpm.

The wide rpm range for the maximum torque – a specific trait of turbocharged engines – helps it deliver a more confident driving experience, with a strong feeling of power across the rpm band. The turbocharger’s on-demand performance also contributes to efficiency because it enables greater power when needed with the lower fuel consumption of a small-displacement engine when it’s not.

The turbocharger is integrated within the exhaust manifold, for reduced weight and greater packaging flexibility. A solid cast crankshaft and forged connecting rods deliver additional durability to support the engine’s pressurized power and torque.

A Hydra-Matic 6T40 six-speed automatic transmission with TAPShift control is matched with the 1.4L turbo engine. It has a unique design, with the planetary gearsets positioned on the same axis as the engine crankshaft centerline, making the entire powertrain unit shorter fore-to-aft. This design enables a shorter overall vehicle length, increased interior space, enhanced safety crush zones and lower weight.

A “steep” first gear and a “tall” overdrive top gear to achieve a wide ratio spread of 6.14:1. This allows Trax to achieve robust acceleration, as well as fuel efficiency and lower engine noise at highway cruising speeds.

Refined ride and handling

Trax is built on a robust global platform and engineered with precise suspension tuning to deliver one of the segment’s quietest and most refined driving experiences. Available all-wheel drive seamlessly shifts power to the rear wheels when required for better traction and handling.

A 100.6-inch (2,555 mm) wheelbase and wide stance – 60.6-inch (1,539 mm) front and rear tracks – contribute to a confident driving experience, while a strong structure enables greater suspension precision and a quiet ride.

A MacPherson strut front suspension is used with coil springs, a large stabilizer bar and side-load-compensated front strut modules.

The rear suspension incorporates a compound crank (torsion beam) design, with a double-wall, tubular V-shape beam profile with gas-charged twin-tube shocks. It combines all the advantages of a conventional torsion beam axle, including minimal space requirements, with low weight and consistent camber control. Noise-damping urethane spring isolators improve ride isolation and dampen noise.

Trax also features a column-mounted, variable-effort electric power steering system that saves fuel compared to a conventional engine-driven power steering pump.

Sixteen-inch wheels are standard on LS and LT (aluminum wheels on LT). LTZ has standard 18-inch aluminum wheels.

Built to protect

Trax incorporates technologies that help avoid crashes and protect occupants in case one occurs. Crash-avoidance technologies include:

  • Standard rearview camera
  • Standard StabiliTrak electronic stability control, incorporating traction control and rollover mitigation features
  • ABS and electronic brake force distribution
  • Cornering brake control and brake assist

The body structure forms a protective cage around the passenger compartment, with 66 percent of the structure composed of high-strength steels, including ultra-high-strength steel. That structural protection is complemented with 10 standard air bags:

  • Driver and front passenger frontal air bags
  • Driver and front passenger knee air bags
  • Front and rear thorax air bags for all outboard positions – including the segment’s only rear-seat-mounted thorax air bags
  • Side curtain air bags for front and rear outboard passengers.

Trax’s safety and security features also include exclusive OnStar technology with Advanced Crash Response System, emergency assistance and more.

Global Trax

Chevrolet Trax was launched in late 2012 in Mexico and Canada as a 2013 model; about 90,000 have been sold in more than 60 global markets. In addition to the United States, the 2015 Trax will also go on sale in China, adding the small SUV to Chevy’s two largest markets. Trax is named after a 2007 concept vehicle.

Founded in 1911 in Detroit, Chevrolet is now one of the world’s largest car brands, doing business in more than 140 countries and selling more than 4.9 million cars and trucks a year.

Chevrolet and GMC Announce CNG Pricing Options

2015 Silverado 2500HD Bi-Fuel

DETROIT  Bi-fuel options, allowing either compressed natural gas or gasoline to power the 2015Chevrolet Silverado and GMC Sierra 2500HD and 3500HD pickups, will start at $9,500. A dedicated CNG option on the 2015 Chevrolet Express and GMC Savana cargo and passenger short-wheelbase vans starts $10,825 for the three-tank system and $12,090 for the four-tank system.

“Based on current average fuel prices, CNG is more than a dollar cheaper than an equivalent gallon of gasoline, giving drivers and businesses an incentive to use CNG to power their vehicles,” said Ed Peper, U.S. vice president, General Motors Fleet and Commercial. “Given the consistent cost savings and expanding infrastructure, both commercial and individual interest in CNG vehicles continues to grow.”

The bi-fuel CNG option will be available on all 2015 Silverado and Sierra 2500HD and 3500HD single-rear-wheel models. The Express and Savana vans have fully dedicated CNG fuel systems – available in three- or four-tank models on cargo vans and exclusively with the three-tank design on passenger vans. 

GM warrants and validates the fuel systems on all of its CNG trucks, vans and the upcoming bi-fuel Chevrolet Impala sedan through its five-year/100,000-mile – whichever comes first – powertrain limited warranty. All major components associated with the CNG system also carry GM service part numbers for availability throughout the largest dealer network in the United States.

CNG versions of the Silverado and Sierra 2500HD double cab and crew cab and the full-size Express and Savana vans are on sale now. The Silverado and Sierra 2500HD regular cab and all 3500HD pickups go on sale in July.

Two GM SUVs score ‘good’ ratings in new crash testing

Image

DETROIT — Only the Chevrolet Equinox and GMC Terrain survived the challenging new small-overlap crash test for mid-sized SUVs from the Insurance Institute for Highway Safety with a “good” rating.

The Equinox, Terrain and Toyota Highlander earned a top safety pick+ award in the test. But the Highlander received an “average” rating from the group.

Introduced in 2012, the small-overlap test re-creates conditions in which the front corner of a vehicle strikes another vehicle or object. During the test, the front quarter of the driver side of the vehicle collides with a barrier at 40 mph.

The test differs from a head-on collision because the front-end crush zone is bypassed, which can result in the passenger compartment collapsing.

“When it comes to mid-sized SUVs, General Motors is showing the way forward,” David Zuby, IIHS vice president, said in a statement. “The Equinox and Terrain score well in all components of the small overlap test — structure, restraints and kinematics, and injury measures for four body regions.”

The IIHS said that the Equinox and Terrain were able to outperform the other SUVs tested because of modifications on 2014 models to the front structure and door-hinge pillars. In the Equinox, the crash test dummy’s movement was controlled and the airbags worked as expected.

The worst-performing mid-sized SUV was the Honda Pilot, in which the driver’s space was “seriously compromised by intruding structure” during the crash. In the worst impact, the parking brake moved 16.5 inches inward, the steering column shifted 5.2 inches to the right and the dummy suffered injuries to the left hip, knee and lower leg.

Also receiving a poor rating was the Mazda CX-9, which had its hinge pillar intrude 17 inches, bringing the left driver-side wheel even with the dummy’s knee. The door frame was so damaged in the crash that the dummy’s head struck it after impacting the front airbag.

The Ford Explorer had its door hinge pillar nearly severed from the door sill in the impact, which led to a moderate overall rating from the group, but a poor structure rating. The Kia Sorento earned a poor overall rating due to poor structure and lower leg and foot scores.
