Components
Engine design
The Corvette ZR1 engine is a heavily modified version of the LS3 Corvette engine, designated the supercharged LS9 Corvette engine. Producing 638 hp (476 kW; 647 PS) and 604 lbf·ft (819 N·m) of torque, it is the most powerful production Corvette to date. The LS9 has a sixth-generation Eaton TVS R2300 roots 4-lobe supercharger with intercoolers from Behr, utilizing an air-to-water, dual-brick design. The supercharger's four-lobe design offers improved efficiency over three-lobe models. To avoid changes to the hood appearance, the supercharger's output was split into two halves. Each cylinder bank has an intercooler.
The cylinder walls of the LS3 are thicker than the Z06's LS7 since the LS3 has a smaller bore. Oil squirters under each piston help cool the pistons. Connecting rods and the inlet valve are made of titanium. Heads are made from a special heat resistant aluminum alloy. The camshaft lift was reduced from the LS7's to improve idle quality. With the addition of the supercharger to the 6.2 liter LS9, the higher lift camshaft was no longer necessary to achieve horsepower targets.
Lubrication is provided by an improved version of the LS7's dry sump system. The new system increases oil capacity from 8.0 to 10.5 quarts (9.94 liters). A new dual gerotor oil pump increases scavenge performance and oil pressure, enabling oil to be delivered under the most extreme conditions. The LS7 oilpan is used for the LS9 with the addition of an oil cooler which is mounted on the left side of the pan.
With the 2011 model, GM offers the optional "Corvette Engine Build Experience," where the customer visits the General Motors’ Performance Build Center to help assemble the LS9 for the ZR1 purchased. Factory technicians supervise the process and the normal warranty covers the engine built by the customer's hands.[1]
Transmission
The ZR1 flywheel has been improved over the 2008 Z06. The flywheel was upgraded by going from six to a 9 bolt design and cutting off nearly 9.8 ounces (278 grams) for improved throttle response and acceleration.
The ZR1 has a 6-speed manual Tremec TR-6060 transmission with a MH3 gearset, while the 2008 Z06 featured the MM6 gearset.
Differential/drive
The differential is a limited slip with carbon and steel plates. The differential uses SAE 5W-80 Dexron LS lubricant.
The two half shafts have different diameters (33mm left, 40mm right), designed to prevent resonance during acceleration and reduce the chances of wheel hop.
Production
Production vehicles are hand assembled in Bowling Green, Kentucky.
Ride control
The name of the ride control system is Magnetic Selective Ride Control (MSRC). MSRC is provided by Delphi Automotive Systems from technology invented by the GM Research Laboratories. The system uses two modes of control: Tour and Sport.
The system offers standing start launch modifications. When launching the ZR1 from a standing start, the shocks are completely softened on launch and stiffened on rebound. The softened shocks on launch aid the ZR1 by allowing weight to transfer to the rear, aiding traction. The ride control standing launch modifications are designed to minimize bounce.
Suspension
The ZR1 features a double-wishbone suspension system and Magnetic Selective Ride Control—which adjusts shock-absorber damping in real time to either "Tour" or "Sport" mode.[2]
The MSRC shocks are automatically adjusted based on driving conditions and vehicle dynamics (cornering, braking, etc.) for optimal handling. The system is adjusted every millisecond to provide sharp handling during spirited driving, and a smooth ride while cruising.[3]
Chassis/body
The chassis, similar to the 2008 Z06, is made of aluminum.[5] To cut weight, many panels are made of carbon fiber. Panels made of carbon fiber are the fenders, hood, roof, splitter, and rocker extensions. To prevent the sun from damaging the binder in the exposedcarbon fiber composite body panels, panels are protected with a clear coating.[6]
The rear wheels are the largest ever mounted on a production Corvette with 335/25 Michelin Pilot Sport PS2 tires on 20 in (510 mm) wheels.
The ZR1 has a length of 176.2 inches (4,480 mm), width of 75.9 inches (1,930 mm), and height of 48.7 inches (1,240 mm). The ZR1 has a curb weight of 3,405 lb (1,544 kg).[5]
Clutch
The 260 mm (10 in) ZF-Sachs twin-plate clutch supplants Z06's 290 mm (11 in) single-plate unit to reduce inertia for better shift feel. The lower clamping force reduces clutch-pedal effort. The clutch upgrade is considered a dramatic improvement over the unit employed within the Z06.
Brakes
The front brake rotors are similar to the carbon ceramic design employed in the Ferrari FXX track car, the difference being a diameter reduction from 15.75 in (400 mm) to 15.5 in (390 mm) for added wheel clearance. The front calipers are Brembo 6-piston units.
Rear calipers are Brembo 4-piston units. The rear brakes are 15 in (380 mm) carbon ceramic rotors, originally employed as the Enzo Ferrari's front rotors. Same as those used in the BMW
M3 GTS.
Both front and rear pads have twice the contact area of the Z06's, as well as the addition of brake pad wear sensors. The brake master cylinder, booster, ABS unit and system controller are now obtained from Bosch instead of Delphi.
As a result, the ZR1 will stop from 60 mph (97 km/h) in a current production car record-breaking 96 feet (29.3 m).
Ignition
Coil packs are identical to those used on the LS3. The coil packs are mounted on the valve covers.
Fuel system
A unique fuel pressure regulator varies pressure between 36.3 and 87.0 psi (250 and 600 kPa) depending on rpm.
Identification
A new magnetic suspension system enables the ZR1 to deliver superior handling and grip to achieve 1.10 g of average lateral acceleration.[4]
The ZR1 features blue badges, engine fuel rail covers, and brake calipers. The hood contains a polycarbonate window which allows the chargecooler to be viewable.[6] Doors and rear body are from the 2006 Z06 except the front fenders were changed to have two horizontal vents. A spoiler which is larger than those on the previous models spans the top rear bumper. Functional fender vents provide engine cooling. The lettering "LS9 Supercharged" can be viewed on top of the plastic supercharger cover through the hood window.

Chevrolet is bringing its EN-V 2.0 to the Sino-Singapore Tianjin Eco-City in China to show off the "Electric Networked-Vehicle" and demonstrate sustainable urban mobility. The small, two-seat EV concept is an updated version of the original EN-V, a vision of getting around in a future world where space is at a premium and clean air is a priority. So what better place to showcase the evolved EN-V than at the Tianjin Eco-City? The Eco-City is being developed as a planned urban space with eco-consciousness built in. The joint venture between China and Singapore offers an alternative to country living and smog-filled cities. Tianjin Eco-City, slated to be completed by 2020, will be able to offer 350,000 inhabitants clean air and water, renewable energy, green transportation and living spaces and, if all goes as planned, jobs for 50 percent of the residents. Currently, only about three square kilometers of the planned 30 square kilometers have been built, with only about 6,000 permanent residents, but there's still time. The EN-V 2.0, as the "Networked" part of its name suggests, not only features mobile internet, but can communicate with other cars around it. Along with GPS and built-in sensors, this connection between vehicles allows the car to drive autonomously (at least in theory - again, there's still time). This is ideal in an urban environment where congestion can be a major issue. The EN-V 2.0 improves upon the original concept with climate control, storage space and all-weather capability, which also make life more bearable and daily commuting possible. We first saw renderings of the updated vehicle in 2012. The Chevrolet EN-V 2.0 will be used in the Eco-City's National Animation Industry Park and Eco-Business Park of the course of the two-week demonstration. Read on below for more in the press release from GM. GM to Demonstrate Chevrolet EN-V 2.0 in Tianjin Eco-City SHANGHAI – General Motors today announced that it will begin demonstrating the Chevrolet EN-V 2.0 (Electric Networked-Vehicle) in the Sino-Singapore Tianjin Eco-City this week, signaling the company's learning and progress in sustainable urban mobility. The demonstration will help GM further understand consumers' usage of low-speed transportation tools for their daily commute. During the two-week demonstration period, the EN-V 2.0s will be used in the National Animation Industry Park and Eco-Business Park inside the Sino-Singapore Tianjin Eco-City.

FLINT, Mich. — General Motors said Tuesday it will add 1,000 workers to build new heavy-duty pickup trucks at its plant in Flint, Michigan, and will give priority to GM workers who were laid off elsewhere. The announcement comes the day after GM said it was starting to hand pink slips to about 4,000 salaried workers in the latest round of a restructuring announced in late November that will ultimately shrink its white-collar workforce in North America by 15 percent out of 54,000. GM has come under fire from U.S. President Donald Trump and Midwestern lawmakers for its plans to stop production at five North American factories and cut up to 15,000 jobs in all. The automaker has said it is trying to find new jobs for 1,500 U.S. hourly workers at the affected plants. Flint's truck plant could be a haven for many of these employees. Sales of heavy-duty pickups in the United States have grown to more than 600,000 vehicles a year, up more than 20 percent since 2013, according to industry data. Prices for luxury models can easily top $70,000. GM on Tuesday will celebrate the launch of a new generation of heavy-duty GMC and Chevrolet pickups at the assembly plant in Flint, Michigan, that is now building all such trucks for the company. Elsewhere in the company on Monday, two people briefed on the cuts in the white-collar salaried workforce said GM is cutting hundreds of jobs at its information technology centers in Texas, Georgia, Arizona and Michigan and more than 1,000 jobs at its Warren, Michigan Tech Center. GM is filing new required mass layoff notices with state agencies and disclosed the cuts to lawmakers. The largest U.S. automaker announced in November it would cut a total of about 15,000 jobs and end production at five North American plants. The cuts include eliminating about 8,000 salaried workers, or about 15 percent. GM cut about 1,500 contract workers in December and said 2,300 salaried workers accepted buyouts, officials said. "These actions are necessary to secure the future of the company, including preserving thousands of jobs in the U.S. and globally. We are taking action now while the overall economy and job market are strong, increasing the ability of impacted employees to continue to advance in their careers, should they choose to do so," GM spokesman Pat Morrissey said, adding the bulk of the cuts should be completed in the next two weeks. Morrissey said GM would provide salaried workers with severance packages and job placement services.

Transport Canada, the auto safety regulator, has opened a probe into braking issues in nearly 250,000 General Motors full-size pickups and SUVs after U.S. officials launched a similar probe last year, the agency said on its website. The U.S. National Highway Traffic Safety Administration (NHTSA) in November into 2.73 million U.S. 2014-2016 model year SUVs and pickups after receiving 487 reports of hard brake pedal effort accompanied by extended stopping distance that were attributed to deterioration of the engine-driven brake assist vacuum pump. Transport Canada's probe covers 249,700 2015 through 2017 model year vehicles including the Cadillac Escalade, Chevrolet Suburban, Chevrolet Tahoe and GMC Yukon as well as 2014-2017 Chevrolet Silverado LD and GMC Sierra LD vehicles. The U.S. agency said it had reports of nine incidents of vehicles incurring damage as a result of colliding with another vehicle or fixed object at low speeds and reports of two injuries. NHTSA said if the pump fails to operate, the amount of brake power assist can be significantly reduced, extending vehicle stopping distance. The NHTSA sent GM an information request in a Feb. 7 letter. A GM spokesman said he had no update on the investigation. Reporting by David Shepardson; editing by Jonathan Oatis
