    2015 Corvette Stingray To Come Available With A Performance Data Recorder


    • The 2015 Chevrolet Corvette Stingray Wants To Help You Do Better On A Racetrack.


    Chevrolet has announced that the 2015 Corvette Stingray will be available with the Performance Data Recorder. The recorder enables drivers to record their hot laps with telemetry overlays to help analyze an determine where they need to improve.

    The Performance Data Recorder was jointly developed by GM and Corvette Racing partner Cosworth. The system is comprised of three different components:

    • A 720p, high-definition camera to record the driver's point-of-view. A microphone is also included for a driver to narrate their lap.
    • Self-contained telemetry recorder that uses a dedicated GPS receiver to provide precise information of where the vehicle is. The recorder also hard-wired into the Stingray’s Controller Area Network, or CAN to access data such as engine speed, gear selection, braking force, and steering angle.
    • Dedicated SD Card Slot in the glovebox to record and transfer data. Dependent on the size of the SD card, you can record up to more than 13 hours of driving time

    The recorder offers four different modes which vary the amount of overlay on the video. They include:

    • Touring Mode – simply records and displays video and audio of the drive with no data overlay
    • Sport Mode – shows fewer details on the overlay but includes key data including speed and g-force
    • Performance Mode – records performance metrics, such as 0 to 60 mph acceleration, 1/4-mile speed and elapsed time, and 0-100-0 mph runs.
    • Track Mode – shows the maximum level of data on the screen, including speed, rpm, g-force, a location-based map, lap time and more.

    Videos can be watched on the Corvette Stingray’s eight-inch color touchscreen or downloaded to a computer.

    “The Performance Data Recorder combines the ability to record and share drive videos with the power of a professional-level motorsports telemetry system. Drivers can easily record and share their experiences driving down the Tail of the Dragon or lapping Road Atlanta. In addition, with the included telemetry software, users can analyze their laps in incredible detail and find opportunities to improve their driving and lap times,” said Tadge Juechter, Corvette chief engineer.

    Pricing hasn't announced for the Performance Data Recorder, but it will be available starting in the third quarter of this year.

    Fast Feedback: Corvette Performance Data Recorder

    • Industry-first system features integrated video, audio, and motorsport-inspired telemetry recording capability

    • HD-quality videos can be reviewed in-car (when parked), or downloaded to a personal computer for sharing via social media

    • Data can be uploaded to Cosworth Toolbox telemetry software, similar to that used by Corvette Racing, to improve driver's techniques and lap times

    LAS VEGAS – At the Consumer Electronics Show today, Chevrolet announced an all-new, industry-first Performance Data Recorder will be available on the 2015 Corvette Stingray. The fully integrated system enables users to record high-definition video, with telemetry overlays, of their drive experiences on and off the track.

    "The Performance Data Recorder combines the ability to record and share drive videos with the power of a professional-level motorsports telemetry system," said Tadge Juechter, Corvette chief engineer. "Drivers can easily record and share their experiences driving down the Tail of the Dragon or lapping Road Atlanta. In addition, with the included telemetry software users can analyze their laps in incredible detail, and find opportunities to improve their driving and lap times." The Performance Data Recorder (PDR) system was developed with Cosworth, the British motorsports-engineering company that also supplies the Corvette Racing team's data acquisition and telemetry electronics system. It will be available with the start of regular 2015 Corvette production, later in the third quarter of 2014. Pricing will be announced closer to launch.

    The PDR system includes three major components, all seamlessly integrated into the Corvette Stingray's interior. First is the 720p, high-definition camera, mounted within the windshield header trim, which records the driver's point-of-view through the windshield. Audio is recorded via a dedicated microphone in the cabin. Second is a self-contained telemetry recorder. The system uses a dedicated GPS receiver that operates at 5 Hz, five times faster than the in-dash navigation system, for more precise positioning and corner traces. The recorder is also hard-wired into the Stingray's Controller Area Network (CAN) to access vehicle information, ranging from engine speed and transmission-gear selection to braking force and steering-wheel angle.

    Finally, the system features a dedicated SD-card slot in the glove box for recording and transferring video and vehicle data. Recording time depends on the capacity of the memory card, but an 8GB card can record approximately 200 minutes, while a 32GB card stores up to about 800 minutes – more than 13 hours of driving time.

    The PDR system can record video with three data overlay options, each rendered in real time:

    • Track Mode – shows the maximum level of data on the screen, including speed, rpm, g-force, a location-based map, lap time, and more.

    • Sport Mode – shows fewer details on the overlay, but includes key data including speed and g-force

    • Touring Mode – no data overlay; it simply records and displays video and audio of the drive

    • Performance Mode – records performance metrics, such as 0 to 60 mph acceleraiton, 1/4-mile speed and elapsed time, and 0-100-0 mph runs.

    The video can be viewed on the Corvette Stingray's eight-inch color touchscreen (when the car is parked), or downloaded to a computer for further editing, and sharing video via social media sites.

    For users who want a more in-depth understanding of their performance, the PDR vehicle data can be opened in the included "Cosworth Toolbox" software, which combines Cosworth's professional-level motorsport data analysis with an easy-to-use graphic interface.

    The Cosworth Toolbox application overlays recorded laps on a Bing-enabled satellite map of the track, and features an easy-to-use interface to compare selected laps in detail, for any requested point on the drive. Comparisons include corner traces, vehicle speed, and cornering force to help drivers improve their driving consistency, and ultimately lap times.

    The ability to review laps between track sessions can identify immediate adjustments for quicker laps in the next session," said Juechter. "It's like having a 32-GB crew chief trackside, proving you with real-time feedback to improve your driving skills."

    This sounds very cool. For those of us that have used laptops to do this, it makes it much easier, but I do wonder if big brother will want to access this info if they use it on public roads. Have to be careful of where one uses it so you do not leave behind evidence if you do something not legal.

    I could see this on a future Fast and Furious movie where they show recording their street race and then going back to fine tune the auto. :P

    I assume any videos will also be automatically streamed to the NSA data centers.. :) I could see this being used by the police to auto-generate tickets.

    This is a private device, so I suppose the police would need a court order to use the data... No?

    Unless people are stupid enough to post videos of them doing 200mph, and people aren't that supid....... Errrr..... I mean..... Maybe they are that stupid :smilewide:

    Wouldn't that be easy to fightin court? As in the means of evidence not being legal, therefore presumption of innocente kicks in?

    This is the same general discussion that circled around black boxes, no?

    Seems privacy rights are a quaint notion from a bygone era. Stay off the grid as much as possible.

      Big November Gains at Chevrolet, Buick, GMC and Cadillac Keep GM the Fastest Growing Automaker
      November U.S. retail market share highest since 2009 Year to Date U.S. Retail Share up 0.5 Percentage Points November Commercial sales were highest since 2008 DETROIT — General Motors (NYSE: GM) sold 197,609 vehicles in November to individual or “retail” customers in the U.S., up 8 percent from last year. Based on initial estimates, GM once again outperformed all full-line manufacturers, led by strong retail sales gains at Chevrolet, Buick, GMC and Cadillac. GM’s November retail sales performance drove GM’s U.S. retail share to its highest November level since 2009.
      Based on initial estimates, GM’s retail market share jumped 0.3 percentage points in November to 16.8 percent.  GM has gained retail market share in 17 of the past 20 months.
      GM’s four U.S. brands posted strong retail sales results in November compared to last year.
      Chevrolet — up 5 percent for its best November since 2004 Buick — up 22 percent for its best November since 2003 GMC — up 9 percent for its best November since 2001 Cadillac — up 17 percent for its best November since 2013 GM’s total U.S. sales in November were 252,644 vehicles, up more than 10 percent from last year.   All four brands outperformed the industry in November with Buick, Cadillac and GMC posting double-digit gains.
      “GM’s November performance reflects the continued strength of our U.S. business.  We gained profitable retail share, commercial and small business deliveries were strong and we commanded the industry’s best average transaction prices,” said Kurt McNeil, GM’s vice president of U.S. Sales Operations. “We are ahead of plan selling down our 2016 model year inventory and we expect to close out December with more retail share growth. GM is heading into 2017 in a position of strength with the planned launch of key new products, like the all-new Chevrolet Equinox, into the heart of the market.” 
      GM’s ATPs, which reflect retail transaction prices after sales incentives, were $35,767 in November, more than $4,000 above the industry average and ahead of last November. 

      Through the first 11 months of the year, GM’s U.S. retail sales were up nearly 2 percent compared to last year. GM gained 0.5 percentage points of U.S. retail market share during that timeframe, the largest retail share gain of any full-line automaker. Year to date, Chevrolet U.S. retail sales are up nearly 3 percent and the brand’s retail share has grown 0.5 percentage points to 11.1 percent. Chevrolet continues to be the U.S. industry’s fastest-growing brand.
      Year to date, Buick retail deliveries have grown more than 5 percent and Buick has gained 0.1 percentage points of retail share.
      GM continues to benefit from a strong U.S. economy and strong retail demand for its products.
      “All economic indicators show significantly improved optimism about the U.S. economy including consumer and business sentiment, which continue to drive a very healthy U.S. auto industry,” said Mustafa Mohatarem, GM’s chief economist. “We believe the U.S. auto industry is well-positioned for sales to continue at or near record levels into 2017.”

      General Motors will begin importing the Colorado and Silverado pickups into China next year, but you'll only be able to buy them in select markets.
      Automotive News explains that many Chinese cities have bans on pickups for the fear of aggravating air pollution and causing more traffic issues. But earlier this year, the Chinese Government lifted the ban in four provinces - Henan, Hebei, Liaoning, and Yunnan - in an effort to jumpstart sales of domestic pickups. GM sees an opportunity with this and wants to explore it. But there is a major downside to this. Since GM will be importing the trucks, they'll be hit with 25 percent tariff by the Chinese Government.

      It was three years ago that Chevrolet showed off the Colorado ZR2 concept at the LA Auto Show. It was a mean looker with an aggressive look, raised suspension, and meaty off-road tires. Imagine our surprise when Chevrolet revealed the production version tonight in Los Angeles.
      The 2017 Colorado ZR2 keeps the mean look of the concept with a new front end treatment, raised hood, skid plates, 31-inch Goodyear Duratrac tires mounted on 17-inch wheels, and an optional spare tire carrier in the bed.
      But under the skin is where the juicy changes are. Chevrolet has widened the track by 3.5-inches, raised the suspension by 2-inches and equipped it with unique spool-valve dampers from Multimatic - yes the same folks who are being tasked with building the upcoming Ford GT. The dampers first used on the Camaro Z/28, come with six different tuning curves up front, and four in the rear to provide better ride and handling characteristics over different terrains. 
      Engine choices include the 3.6L V6 (308 horsepower, 275 pound-feet) and 2.8L Duramax Turbodiesel (181 horsepower, 369 pound-feet). The four-wheel drive system features a set of electronic-locking differentials for the front and rear axles.
      No word on pricing on when the Colorado ZR2 will arrive at dealers.

      New Colorado ZR2 A "Segment of One" Among Off-Road Pickups
      New performance variant of the Chevrolet Colorado excels in tight two-tracks, technical rock-crawling, fast desert running and on pavement LOS ANGELES — Just as introduction of the Chevrolet Colorado reset the bar for mid-size trucks, the new Colorado ZR2 is poised to reset expectations for off-road trucks. Chevy’s new performance halo for the Colorado lineup will feature more off-road technology than any other mid-size pickup when it goes on sale.
      The ZR2 is effectively a segment of one, combining the nimbleness and maneuverability of a mid-size pickup with a host of new off-road features and the most off-road technology of any vehicle in its segment.
      Compared to a standard Colorado, the ZR2 features a much wider track and a lifted suspension. Functional rockers have been added for better performance over rocks and obstacles, and the front and rear bumpers have been modified for better off-road clearance.
      Class-exclusive features include front and rear electronic locking differentials, available diesel engine, and the first off-road application of Multimatic Dynamic Suspensions Spool Valve (DSSVTM) damper technology.
      As a result, the Colorado ZR2 delivers exceptional performance in a variety of scenarios – from technical rock crawling to tight two-track trails to high-speed desert running to daily driving.
      “Our engineers have been incredibly successful developing Corvette and Camaro performance variants with broad performance envelopes,” said Mark Reuss, executive vice president, Global Product Development, Purchasing and Supply Chain. “The ZR2 applies that same philosophy to off-road performance. You can go rock crawling on Saturday, desert running on Sunday, and comfortably drive to work on Monday. This truck can do it all, and do it all well.”
      First off-road application of Multimatic DSSV dampers
      To achieve this unprecedented balance of on- and off-road performance, the Chevy engineering team turned to a surprising partner in creating the ZR2’s dampers, which are the heart of any off-road truck.
      Multimatic Inc., based in Markham, Ontario, is a renowned maker of high-performance Dynamic Suspensions Spool Valve (DSSV) dampers as used in championship-winning motorsport vehicles, including recent Formula One winners.
      The first volume production vehicle to use DSSV dampers was the 2014 Chevrolet Camaro Z/28. The 2017 Chevrolet Colorado ZR2 will be the first application of Multimatic DSSV damper technology to an off-road vehicle.
      “From our experience on Z/28, we knew the performance advantages offered by DSSV dampers, “ said Mark Dickens, executive director, Performance Variants, Performance Parts and Motorsports Engineering, Chevrolet. “We also know that Multimatic’s motorsport development mentality would allow us to bring a uniquely precise and repeatable custom damper to market even more quickly than a traditional damper system.”
      Compared to deflected-disk valving common on most dampers, the ZR2 employs spool valves that offer increased precision and manufacturing repeatability along with enhanced ride and handling performance both on- and off-road.
      The Colorado ZR2’s DSSV dampers are position-sensitive. Their aluminum bodies each house two spool valves providing both compression and rebound damping optimized for everyday driving. During extreme off-road use, a third, piston-mounted spool valve delivers additional, uniquely tuned, compression damping. The front dampers also employ a separate rebound valve, which comes into play when the suspension approaches full extension.
      “A traditional, deflected-disc damper only offers two force-velocity curves for tuning,” Dickens said. “The ZR2 dampers offer six tuning curves for the front, four at the rear. For the driver, this translates to greater confidence and control in a wider range of driving experiences.”
      Design meets mud, sand and rock
      Visually, the production version of the Colorado ZR2 closely resembles the concept shown at the 2014 Los Angeles Auto Show. Consumer response to that concept was so overwhelming, the team knew they needed to carry as much of the original design into production as possible.
      “For both the concept and the production versions of ZR2, the exterior design was shaped by the desire to improve capability driving over mud, sand and rock,” said Rich Scheer, director of design for Chevrolet Truck. “The wider, more aggressive stance, modified front and rear bumpers, and even the bed-mounted, spare-tire carrier all improve performance driving over rough terrain.”
      Compared to a Colorado Z71, the ZR2 has a more aggressive side profile, with the suspension lifted two inches for greater ground clearance. The steel-tube, functional rocker protectors will be standard equipment on the ZR2, and are strong enough to protect the body side while dragging the truck against a rock face.
      The ZR2 also features 17 x 8 inch aluminum wheels, in a pattern exclusive to the ZR2, wrapped in 31-inch Goodyear Duratrac off-road tires for exceptional traction. 
      The front and rear track has been widened by three-and-a-half inches, with new cast-iron control arms for greater durability in off-road situations. As a result, the ZR2 offers greater wheel travel and stability while traversing steep grades.
      The front bumper of the ZR2 has tapered ends, to increase the tire clearance when approaching obstacles. The bumper also integrates a thick, aluminum skid plate protecting the radiator and engine oil pan, while the transfer case is protected by an additional shield. Above the bumper, the ZR2 features a more aggressive grille and hood – with black insert – to complement the other exterior changes.
      A bed-mounted spare tire carrier, seen on reveal vehicles at the Los Angeles Auto Show, will be available as an accessory. “The bed-mounted spare tire adds a rugged look to ZR2, and serves a functional purpose. By relocating the spare to the bed, ZR2’s departure is improved and prevents any damage to the spare when you’re crawling over obstacles,” said Scheer.
      Class-exclusive electronic lockers, available diesel engine
      The ZR2 also features the most sophisticated four-wheel drive system in the segment. With class-exclusive, electronic-locking differentials front and rear and Chevrolet’s AutoTrac transfer case, the ZR2 offers nine drive configurations:
      2WD 2WD, locked rear differential Auto 4WD Auto 4WD, locked rear differential 4WD Hi, locked transfer case 4WD Hi, locked transfer case and locked rear differential 4WD Lo, locked transfer case 4WD Lo, locked transfer case and locked rear differential 4WD Lo, locked transfer case, locked front and rear differentials Extensive work was done to integrate the electronic lockers and allow them to seamlessly interact with the traction control, stability control, and hill-descent control. In addition, a new “Off-Road Mode” button, in combination with the traction control switch, allows the anti-lock brakes, traction control, and stability control calibrations to be tailored to different driving conditions. Off-road Mode also alters the throttle progression and shifts calibrations to give the driver better control and responsiveness.
      The ZR2 shares its powertrains with the 2017 Colorado, and it will be the only extreme production off-road truck to offer the choice of gas or diesel engines.
      The all-new 3.6L V-6, mated to a class-exclusive Hydra-Matic 8L45 8-speed automatic transmission, yields 308 horsepower and 275 lb-ft of torque, while the class-exclusive Duramax diesel engine produces 181 horsepower and 369 lb-ft of torque and will provide excellent range to overland drivers.
      Even with all of the off-roading upgrades over the base truck, the ZR2 can still tow up to 5,000 lbs. – enough to pull a camper, trailer dirt bikes, jet skis, snow mobiles and other toys – or carry 1,100 lbs. of payload.
      As such, the Colorado ZR2 offers a distinct position in the market: Compared to other midsize trucks, the Colorado offers an unrivaled suite of powertrain technologies; compared to full-size off-road trucks, the ZR2 is about a foot narrower and 500 pounds lighter, enabling greater agility over obstacles and better trail access.
      “It’s amazing what a difference a foot of width makes off road,” said Dickens. “The smaller size of the Colorado is a huge enabler for taking the ZR2 more places, and getting it through tighter spots than you could access with a full-size truck.”
      New, off-road development track at GM’s Yuma Proving Ground
      For the development of the Colorado ZR2, Chevrolet developed new off-road test areas at General Motors’ Yuma, Arizona Proving Ground.
      The Yuma Proving Ground is located on 2,400 acres of land in southeastern Arizona. Opened in 2009, Yuma features a range of tracks, laboratories and courses. 
      The new off-road facility features a multitude of off-road simulations, including high-speed desert sand trails; low-speed, loose river rock crossings; and steep, technical hill climbs and descents.
      Yuma Proving Ground’s new off-road course allowed the team to test multiple iterations of components on the ZR2 is a single day. These components were then tested a real-world facilities like Moab, Johnson Valley, and Rubicon to ensure the ZR2 is trail-ready right from the factory.

      It was three years ago that Chevrolet showed off the Colorado ZR2 concept at the LA Auto Show. It was a mean looker with an aggressive look, raised suspension, and meaty off-road tires. Imagine our surprise when Chevrolet revealed the production version tonight in Los Angeles.
      The 2017 Colorado ZR2 keeps the mean look of the concept with a new front end treatment, raised hood, skid plates, 31-inch Goodyear Duratrac tires mounted on 17-inch wheels, and an optional spare tire carrier in the bed.
      But under the skin is where the juicy changes are. Chevrolet has widened the track by 3.5-inches, raised the suspension by 2-inches and equipped it with unique spool-valve dampers from Multimatic - yes the same folks who are being tasked with building the upcoming Ford GT. The dampers first used on the Camaro Z/28, come with six different tuning curves up front, and four in the rear to provide better ride and handling characteristics over different terrains. 
      Engine choices include the 3.6L V6 (308 horsepower, 275 pound-feet) and 2.8L Duramax Turbodiesel (181 horsepower, 369 pound-feet). The four-wheel drive system features a set of electronic-locking differentials for the front and rear axles.
      No word on pricing on when the Colorado ZR2 will arrive at dealers.

      New Colorado ZR2 A "Segment of One" Among Off-Road Pickups
      New performance variant of the Chevrolet Colorado excels in tight two-tracks, technical rock-crawling, fast desert running and on pavement LOS ANGELES — Just as introduction of the Chevrolet Colorado reset the bar for mid-size trucks, the new Colorado ZR2 is poised to reset expectations for off-road trucks. Chevy’s new performance halo for the Colorado lineup will feature more off-road technology than any other mid-size pickup when it goes on sale.
      The ZR2 is effectively a segment of one, combining the nimbleness and maneuverability of a mid-size pickup with a host of new off-road features and the most off-road technology of any vehicle in its segment.
      Compared to a standard Colorado, the ZR2 features a much wider track and a lifted suspension. Functional rockers have been added for better performance over rocks and obstacles, and the front and rear bumpers have been modified for better off-road clearance.
      Class-exclusive features include front and rear electronic locking differentials, available diesel engine, and the first off-road application of Multimatic Dynamic Suspensions Spool Valve (DSSVTM) damper technology.
      As a result, the Colorado ZR2 delivers exceptional performance in a variety of scenarios – from technical rock crawling to tight two-track trails to high-speed desert running to daily driving.
      “Our engineers have been incredibly successful developing Corvette and Camaro performance variants with broad performance envelopes,” said Mark Reuss, executive vice president, Global Product Development, Purchasing and Supply Chain. “The ZR2 applies that same philosophy to off-road performance. You can go rock crawling on Saturday, desert running on Sunday, and comfortably drive to work on Monday. This truck can do it all, and do it all well.”
      First off-road application of Multimatic DSSV dampers
      To achieve this unprecedented balance of on- and off-road performance, the Chevy engineering team turned to a surprising partner in creating the ZR2’s dampers, which are the heart of any off-road truck.
      Multimatic Inc., based in Markham, Ontario, is a renowned maker of high-performance Dynamic Suspensions Spool Valve (DSSV) dampers as used in championship-winning motorsport vehicles, including recent Formula One winners.
      The first volume production vehicle to use DSSV dampers was the 2014 Chevrolet Camaro Z/28. The 2017 Chevrolet Colorado ZR2 will be the first application of Multimatic DSSV damper technology to an off-road vehicle.
      “From our experience on Z/28, we knew the performance advantages offered by DSSV dampers, “ said Mark Dickens, executive director, Performance Variants, Performance Parts and Motorsports Engineering, Chevrolet. “We also know that Multimatic’s motorsport development mentality would allow us to bring a uniquely precise and repeatable custom damper to market even more quickly than a traditional damper system.”
      Compared to deflected-disk valving common on most dampers, the ZR2 employs spool valves that offer increased precision and manufacturing repeatability along with enhanced ride and handling performance both on- and off-road.
      The Colorado ZR2’s DSSV dampers are position-sensitive. Their aluminum bodies each house two spool valves providing both compression and rebound damping optimized for everyday driving. During extreme off-road use, a third, piston-mounted spool valve delivers additional, uniquely tuned, compression damping. The front dampers also employ a separate rebound valve, which comes into play when the suspension approaches full extension.
      “A traditional, deflected-disc damper only offers two force-velocity curves for tuning,” Dickens said. “The ZR2 dampers offer six tuning curves for the front, four at the rear. For the driver, this translates to greater confidence and control in a wider range of driving experiences.”
      Design meets mud, sand and rock
      Visually, the production version of the Colorado ZR2 closely resembles the concept shown at the 2014 Los Angeles Auto Show. Consumer response to that concept was so overwhelming, the team knew they needed to carry as much of the original design into production as possible.
      “For both the concept and the production versions of ZR2, the exterior design was shaped by the desire to improve capability driving over mud, sand and rock,” said Rich Scheer, director of design for Chevrolet Truck. “The wider, more aggressive stance, modified front and rear bumpers, and even the bed-mounted, spare-tire carrier all improve performance driving over rough terrain.”
      Compared to a Colorado Z71, the ZR2 has a more aggressive side profile, with the suspension lifted two inches for greater ground clearance. The steel-tube, functional rocker protectors will be standard equipment on the ZR2, and are strong enough to protect the body side while dragging the truck against a rock face.
      The ZR2 also features 17 x 8 inch aluminum wheels, in a pattern exclusive to the ZR2, wrapped in 31-inch Goodyear Duratrac off-road tires for exceptional traction. 
      The front and rear track has been widened by three-and-a-half inches, with new cast-iron control arms for greater durability in off-road situations. As a result, the ZR2 offers greater wheel travel and stability while traversing steep grades.
      The front bumper of the ZR2 has tapered ends, to increase the tire clearance when approaching obstacles. The bumper also integrates a thick, aluminum skid plate protecting the radiator and engine oil pan, while the transfer case is protected by an additional shield. Above the bumper, the ZR2 features a more aggressive grille and hood – with black insert – to complement the other exterior changes.
      A bed-mounted spare tire carrier, seen on reveal vehicles at the Los Angeles Auto Show, will be available as an accessory. “The bed-mounted spare tire adds a rugged look to ZR2, and serves a functional purpose. By relocating the spare to the bed, ZR2’s departure is improved and prevents any damage to the spare when you’re crawling over obstacles,” said Scheer.
      Class-exclusive electronic lockers, available diesel engine
      The ZR2 also features the most sophisticated four-wheel drive system in the segment. With class-exclusive, electronic-locking differentials front and rear and Chevrolet’s AutoTrac transfer case, the ZR2 offers nine drive configurations:
      2WD 2WD, locked rear differential Auto 4WD Auto 4WD, locked rear differential 4WD Hi, locked transfer case 4WD Hi, locked transfer case and locked rear differential 4WD Lo, locked transfer case 4WD Lo, locked transfer case and locked rear differential 4WD Lo, locked transfer case, locked front and rear differentials Extensive work was done to integrate the electronic lockers and allow them to seamlessly interact with the traction control, stability control, and hill-descent control. In addition, a new “Off-Road Mode” button, in combination with the traction control switch, allows the anti-lock brakes, traction control, and stability control calibrations to be tailored to different driving conditions. Off-road Mode also alters the throttle progression and shifts calibrations to give the driver better control and responsiveness.
      The ZR2 shares its powertrains with the 2017 Colorado, and it will be the only extreme production off-road truck to offer the choice of gas or diesel engines.
      The all-new 3.6L V-6, mated to a class-exclusive Hydra-Matic 8L45 8-speed automatic transmission, yields 308 horsepower and 275 lb-ft of torque, while the class-exclusive Duramax diesel engine produces 181 horsepower and 369 lb-ft of torque and will provide excellent range to overland drivers.
      Even with all of the off-roading upgrades over the base truck, the ZR2 can still tow up to 5,000 lbs. – enough to pull a camper, trailer dirt bikes, jet skis, snow mobiles and other toys – or carry 1,100 lbs. of payload.
      As such, the Colorado ZR2 offers a distinct position in the market: Compared to other midsize trucks, the Colorado offers an unrivaled suite of powertrain technologies; compared to full-size off-road trucks, the ZR2 is about a foot narrower and 500 pounds lighter, enabling greater agility over obstacles and better trail access.
      “It’s amazing what a difference a foot of width makes off road,” said Dickens. “The smaller size of the Colorado is a huge enabler for taking the ZR2 more places, and getting it through tighter spots than you could access with a full-size truck.”
