    2013 SEMA Show: Chevrolet Reveals The Silverado Cheyenne Concept



    William Maley

    Staff Writer - CheersandGears.com

    November 3, 2013

    Years ago, automakers and enthusiasts were enthralled with the likes of high-performance pickup trucks. Models such as the Chevrolet 454SS, GMC Syclone, Ford Lightning, and Dodge Ram SRT-10. But as time went on, the trucks and the interest drifted away. However, the idea of high-performance pickups could be coming back. Just before the opening of the SEMA show, Chevrolet unveiled the Silverado Cheyenne concept.

    The Silverado Cheyenne concept takes a standard regular-cab Silverado and drops in a 6.2L EcoTec V8 with 420 horsepower and 460 pound-feet of torque. Chevrolet also dropped 200 pounds out of the Cheyenne concept by replacing the standard bumpers, tailgate, and cargo box with carbon fiber parts.

    Other changes to the Silverado Cheyenne include lowered ride height, a rear stabilizer bar, and a Borla exhaust. A set of Brembo carbon ceramic brakes and nineteen-inch wheels come from the Camaro Z/28.

    "The Cheyenne concept explores the performance possibilities of the all-new Silverado, which is already built on a mass-efficient layout and delivers a greater balance of performance and efficiency than any other full-size truck in Chevrolet's history," said Chris Perry, vice president of Chevrolet marketing.

    Now, the Silverado Cheyenne is just a concept for now. But Perry did say "but we are continually exploring new ways to give Silverado customers more." Let's hope the Cheyenne is one of those ways.

    Silverado Cheyenne Concept: Mini Mass, Max Performance

    2013-11-03

    LAS VEGAS – The Chevrolet Silverado Cheyenne concept vehicle to be unveiled at the SEMA Show on Monday, Nov. 4, embraces the adage that less is more. The performance-oriented version of the all-new 2014 Silverado regular cab combines a reduced curb weight with the performance of the new 420-horsepower 6.2L V-8 for a strong power-to-weight ratio and exhilarating performance.

    A lowered ride height, a rear stabilizer bar and Brembo carbon ceramic brakes complement the Cheyenne concept's high-performance character with enhanced handling and braking capability.

    "The Cheyenne concept explores the performance possibilities of the all-new Silverado, which is already built on a mass-efficient layout and delivers a greater balance of performance and efficiency than any other full-size truck in Chevrolet's history," said Chris Perry, vice president of Chevrolet marketing.

    The unique lightweight features built into the concept vehicle include carbon fiber replacements for the bumpers, tailgate and inner cargo box, shaving approximately 200 pounds from the 4,503 pounds base curb weight of a 5.3L-equipped Silverado regular cab with a 6'6" box.

    Cheyenne designers matched the form of the lightweight components with their low-mass function. The carbon fiber front bumper includes racing-inspired ground effects styling complemented by carbon body-side ground effects while the carbon fiber tailgate incorporates a spoiler. The hood features a Camaro Z/28-inspired extractor vent.

    The Camaro Z/28 Brembo carbon ceramic brakes save more weight because the carbon ceramic-matrix rotors are significantly lighter than conventional steel rotors. On the Camaro Z/28, for example, they save more than 20 pounds – and it saves un-sprung weight, too, which enhances driving performance with more immediate and direct handling. The truck rolls on charcoal-painted 19-inch Camaro Z/28 aluminum wheels and high-performance tires.

    The Cheyenne diet removes the trailer hitch, spare tire, interior center console and some of the sound-deadening material. The truck also has a lightweight aluminum driveshaft and composite rear leaf springs.

    "Lightweighting is a time-honored method of making the most of a vehicle's performance which Chevrolet has demonstrated time and again with vehicles like the original 2001 Corvette Z06 and the 2014 Camaro Z/28," said Perry. "And like those vehicles, the Cheyenne complements its lower weight with more horsepower."

    The all-new EcoTec3 6.2L V-8 that powers the concept truck is rated at 420 horsepower and 460 lb-ft of torque – the most power in the light-duty truck segment. It's unavailable in regular-production Silverado regular cab models, giving the Cheyenne a 65-horsepower and 77 lb-ft boost over the production 5.3L V-8. A Borla performance exhaust system adds an authoritative note to the 6.2L's output.

    What remains is the Silverado's production six-speed automatic transmission, which features hill descent control, as well as fuel-saving electric power steering and StabiliTrak electronic stability control with hill start assist.

    Inside, the Cheyenne's performance theme is conveyed with Recaro sport seats and a flat-bottom steering wheel, similar to the steering wheel offered in the Camaro ZL1. Available safety features, including lane departure warning, front and rear park assist and a rear-vision camera, enhance safety without detracting from the truck's performance.

    All Silverado models feature a fully boxed frame that serves as the foundation for their strength and capability. The main rails and major cross members are formed from high-strength steel, providing a rigid base for maximum hauling capability.

    "Elements such as high-strength steel in the frame and body structure are found on all production models, while some also feature aluminum suspension components, contributing to the Silverado's everyday performance. With the Cheyenne concept, we've taken the low-mass concept to a new level – with exciting results," Perry said.

    "It is only a concept right now, but we are continually exploring new ways to give Silverado customers more."

    Naw, Blue is Chevy Color where if this was a GMC, then I would agree with Red trim.

    I think they should have went with yellow - throw back to the old late '70s C-series trucks (and would have looked better with the gold bowtie):

    Interesting... in a way GM is proving that there is a replacement for displacement. 420HP and 460 lb-ft of torque is just above the 420hp / 430 lb-ft that the Cadillac 3.6 TT produces....

    I haven't seen the 6.2 liter power curves to compare, but I bet with the way the 3.6TT produces its torque, that it produces more torque at a low RPM than the 6.2 does.

    It would make for an interesting "What if?!" scenario.

    Ocnblu you do not think that a 6.2L TT V8 would beat the Supercharged V8? Chevy can have a mean Full Size SS truck and GMC can have their midsize/small Canyon GMC Syclone with the 3.6L V6 TT AWD. This would give each a special performance truck for the enthusiast.

    Scroll down to the end of this post to see dyno results for a C7 with the new LT1, the torque curve looks pretty good to me.

    I'm not saying it was bad... just that the 3.6TT's torque curve is nearly flat and it hits max torque at a fairly low RPM (around 1700 if I recall)

      Most of us knew this was going happen, but there were some that hoping that somehow the Chevrolet SS would continue on after production of the Holden VF Commodore ended. To those who fall into this camp, it is time to move on as the SS will be no more after 2017.
      Alan Batey, head of GM North America confirmed this yesterday at the Detroit Auto Show. Batey also said there would not be a replacement for the rear-drive sedan.
      “Obviously it’s unlikely there is anything to follow because of what is going on in Australia. It was an optimistic play from our perspective and it’s played out well and been a nice addition to the range. It’s not mainstream. It’s small volume,” said Batey
      In 2016, Chevrolet moved 3,013 SS sedans.

      The current Chevrolet Traverse has been with us for nine years and it was time for a replacement. This morning at the Detroit Auto Show, Chevrolet introduced the 2018 Traverse.
      The new Traverse's shape carries the spirit of the last-generation GMC Acadia. The shape is boxier with both the front and rear being squared-off. Chevrolet's new dual grille design and narrow headlights are present. In terms of size, the Traverse has grown with overall length measuring 204.3 inches long, riding on a 120.9-inch wheelbase. This makes it slightly bigger than a Chevrolet Tahoe (203.9 inches long, 116-inch overall wheelbase). Despite the increase in size, Chevrolet was able to slice off 351 pounds from the new Traverse (note: comparing front-wheel drive models).
      Inside, Chevrolet promises best in class head and legroom for those sitting in the second and third-row seats. This does come at a price as cargo space does decrease. Behind the third-row, the Traverse will offer 23 cubic feet, which beats the likes the Ford Explorer (21 cubic feet). Fold both rows and space increases to 99 cubic feet. Other interior details include either seven or eight-inch infotainment touchscreen, Apple CarPlay and Android Auto compatibility; OnStar 4G LTE with Wi-Fi, and USB ports for all three-rows.
      Most Traverse models will come with the existing 3.6L V6 producing 305 horsepower and 260 pound-feet of torque. This has us scratching our heads since this engine was one our biggest issues with the current Chevrolet Traverse (and Buick Enclave). The new Traverse RS will use a new 2.0L turbo-four making 255 horsepower and 295 pound-feet of torque. Again, this is slightly odd as the RS is being positioned as the sporty-looking model with blacked-out elements. Both engines will come paired with a nine-speed automatic and front-wheel drive. The V6 will only have the option of all-wheel drive. Speaking of all-wheel drive, the top-line High Country will come with the twin-clutch all-wheel drive system found in the Cadillac XT5. This system can decouple the rear-axle to help with fuel economy.

      The 2018 Chevrolet Traverse will arrive at dealers this fall.
      Chevrolet Introduces the 2018 Traverse
      Bold, refined new look with expected segment-best cargo space, third-row legroom DETROIT — Chevrolet today introduced the all-new 2018 Traverse. Wrapped in bold and refined styling, the completely redesigned Traverse offers technologies to help keep passengers of all ages and lifestyles comfortable and connected.
      Traverse will deliver what is expected to be best-in-class third-row legroom, maximum cargo room and passenger volume with an enhanced roster of available active safety features. 
      “The all-new Traverse offers the ultimate in style and convenience for the segment, with the versatility customers need and a thoughtful, spacious design they’ll love,” said Alan Batey, president of GM North America and brand chief, Global Chevrolet. “It’s the midsize SUV designed to help keep you safe, comfortable and connected.”
      When it goes on sale this fall, the 2018 Traverse will be the fourth updated crossover or SUV from Chevrolet within a year, joining the Trax, Bolt EV and 2018 Equinox, further strengthening the brand’s crossover and SUV lineup.
      “Nobody in the industry offers a broader, fresher lineup of SUVs and crossovers than Chevrolet,” said Batey. “From the all-electric Bolt EV to America’s longest-running nameplate, Suburban, we’ve got something for every customer and lifestyle.”
      Bold and refined 
      The 2018 Traverse has a new look inspired by Chevrolet’s full-size SUVs, with purposeful proportions complemented by premium cues such as chrome accents, LED signature lighting and available D-Optic LED headlamps.
      Chevrolet is adding two new trim levels for the 2018 Traverse — the sporty RS and luxurious High Country — to offer customers more choices for a personalized appearance.
      The new RS package includes unique, blacked-out exterior cues with a black chrome grille, black bowtie, 20-inch wheels and more.
      The High Country trim features premium content and technology, including a unique interior trim featuring Loft Brown leather appointments with suede accents, 20-inch polished wheels, High Country badging, D-Optic headlamps, standard twin-clutch AWD and power-fold third row seats.
      “The all-new Traverse blends Chevrolet’s characteristic SUV cues with capability and refinement,” said John Cafaro, executive director, Global Chevrolet Design. “Inside and out, it offers style with a purpose.”
      With available seating for up to eight and a longer wheelbase than the current model, the Traverse has few peers when it comes to capacity and roominess. In fact, the new Traverse is expected to offer best-in-class passenger volume as well as max cargo room at 98.5 cubic feet (2,789 liters), while greater storage options and larger bins throughout the ergonomically optimized cabin are designed to enhance convenience and versatility.
      Loading the Traverse is a breeze with a new Chevrolet bowtie logo lamp feature illuminating the ground to show where drivers need to place a foot to activate the available hands-free power liftgate.
      A new split-folding second-row seat improves on the Traverse’s original Smart Slide® feature. The curbside seat is capable of tipping up and sliding forward, even with a forward-facing child seat in place, to provide open and easy access to the third row.  Third-row legroom is expected to be the most spacious in the segment at 33.7 inches (856 mm).
      Connected and protected
      The 2018 Traverse offers purposeful technology designed to help keep passengers safe, comfortable and connected.
      Chevrolet’s latest connectivity technologies include available 7- and 8-inch-diagonal MyLink infotainment systems designed to support Apple CarPlay and Android Auto, as well as an available OnStar 4G LTE Wi-Fi hotspot. (Apple CarPlay and Android Auto are products of Apple and Google and their terms and privacy statements apply.  Requires compatible smartphone and data plan rates apply.)
      Passengers will have access to USB charging ports in all three seating rows, available wireless charging and steering wheel-mounted phone and audio controls. Chevrolet’s Rear Seat Reminder feature is standard on all trim levels.
      When it comes to helping to protect passengers, a comprehensive suite of available safety technologies and adaptive crash-avoidance features offers ease of use and added peace of mind, with new available features including:
      Surround Vision D-Optic LED headlamps (standard on High Country and Premier) Lane Keep Assist with Lane Departure Warning Front Pedestrian Braking Forward Collision Alert Low and High-Speed Forward Automatic Braking. Teen Driver is standard, allowing parents to set certain controls and review performance in order to help encourage better driving habits, even when parents are not in the vehicle. 
      Performance and efficiency
      A new 3.6L V-6 and nine-speed automatic transmission form the standard propulsion system, expected to offer nearly 10 percent more horsepower than the current model and a GM-estimated 25 mpg highway (FWD). The combination also supports an estimated 5,000-pound (2,268 kg) trailering capacity when properly equipped.
      Sporting the new RS trim, the Traverse will exclusively feature a 2.0L turbocharged engine that provides a unique driving experience, with more maximum torque than the V-6. It is also paired with the nine-speed automatic transmission.
      Both engines feature new intelligent stop/start technology that determines the best times for fuel-saving engine-stop events, based on a variety of driving factors.
      New Traction Mode Select is standard on all models and allows the driver to make real-time adjustments to the vehicle’s driving mode to account for varying road conditions. On available AWD models, it also allows the system to be completely disconnected from the rear axle, which helps save fuel and enhances refinement.
      High Country’s exclusive Advanced AWD system employs twin-clutch technology that optimizes traction for every condition it encounters. It is engineered for optimal performance in wet, snowy and icy conditions, while also providing enhanced stability in dry conditions.

      It seems dual overhead cams are making a return to the Corvette in one application. A set of GM service documents made their way on to Reddit sometime this morning. In the documents, there is a 6.2L DOHC V8 with LT5 code. Furthermore, the engine application corresponds to the 2018 Corvette. There isn't any indication of forced-induction being used for this engine.
      LT5 holds a special place in Corvette history. This was the code used for the only Corvette to ever feature a DOHC V8, the C4 ZR-1. 
      What could this engine be used for? The Drive believes this engine could be used for the mid-engine Corvette since it is a break from the traditional. We're wondering if there could be track-special Corvette that could use this engine.
