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.

In a crash test of 11 of the smallest cars on the market, only one vehicle received an acceptable rating. The rest received marginal or poor ratings in the study, providing evidence that supports a widely held notion that smaller cars are among the least safe on the road. No other vehicle group has performed as poorly on a new crash test than these mini cars, says the Insurance Institute for Highway Safety, the nonprofit group that conducted the testing. The latest results of which were released Wednesday. The Chevrolet Spark was the only car earning an overall "acceptable" rating on the small-front overlap test, and even that vehicle had its shortcomings, IIHS said. "Small lightweight vehicles have an inherent safety disadvantage," said Joe Nolan, the senior vice president for vehicle research at IIHS. "That's why it's even more important to choose one with the best occupant protection. Unfortunately, as a group, minicars aren't performing as well as other vehicle categories." The Mazda2, Kia Rio, Toyota Yaris and certain Ford Fiesta models all received "marginal" overall grades on the test, while the Mitsubishi Mirage, Nissan Versa, Toyota Prius C, Hyundai Accent, Fiat 500 and Honda Fit all earned "poor" ratings. Results from these sub-compact cars fare much worse than vehicles sized just a little bit bigger, IIHS said. Among 17 cars evaluated in the small category, five earned "good" ratings and five more earned "acceptable." Only introduced a year ago, the small-front overlap test has quickly become a key indicator of differences in automotive safety. IIHS introduced it as a way to replicate what happens when the front corner of a vehicle collides with a tree or utility pole at 40 miles per hour. In the real world, these sorts of accidents are more dangerous than others, in part because they bypass the front-end crush zones on most cars.

Without a grade of acceptable or better, they cannot qualify for the IIHS' overall Top Safety Pick+ honor, given annually to the safest models on the market.

Some police in Los Angeles will be riding Zero MMX electric motorcycles on duty. The LAPD is adding the fully electric police/military all-terrain bikes to its patrol fleet. According to Officer Steve Carbajal of the department's off-road unit, "It costs less than 50 cents to charge compared to using gallons of gas, maintenance is simple, and the community appreciates how quiet they are." The electric bikes, with their lack of noise and a headlight the rider can turn off, also have the benefit of stealth, giving the officers what Carbajal calls "an added tactical advantage." The MMX also has swappable batteries, is designed for quick ignition and has power reserve capabilities so the rider won't be caught with a dead battery while chasing down a perp. Read more at Ride Apart. Remember when it seemed like we'd never run out of oil, and giving your buddy five bucks for gas was actually a worthwhile gesture? Drivers of classic cars in Detroit were able to fill up their tanks at gas prices corresponding to their model year, thanks to a promotion by Hagerty Insurance for National Collector Car Appreciation Day on July 11. That meant prices from 21 to 90 cents a gallon, as the cars that showed up ranged from the years 1929 to 1989. That's about as affordable as charging your EV. Head over to Autoweek for more details and some photos from the event. The next-generation Chevrolet Volt will likely benefit from a new inverter being developed by General Motors. GM is about two-thirds of the way through the development of the new inverter, which should be ready in January 2016. The inverter, which has a peak output of 55 kilowatts a continuous output of 33 kilowatts, will be adaptable for use in other GM vehicles. Chevrolet is working to reduce the Volt's production costs by $10,000 per vehicle, which should make it more affordable, and the new inverter could help reach that goal should it make its way into the car. Read more at Green Car Reports. Hyundai is likely planning some interesting powertrain changes for the 2016 Tucson, says Green Car Reports. Plug-in hybrid? Maybe. Diesel? Probably not. "We are covering the waterfront on all alternative fuel strategies, from standard hybrid, to plug-in, battery-electric, and fuel cell," says Hyundai's US Chief Dave Zuchowski.
