New for 2013
- 60th Anniversary Design Package
- Available black-painted aluminum wheels
- Exterior colors: the return of Black and new Night Race Blue Metallic
The ZR1 is the ultimate expression of Corvette’s technology-driven performance legacy, which stretches six decades. That milestone is commemorated in 2013 with an available 60th Anniversary Design Package. It is also the final year for the current “C6” generation of the Corvette.
Corvette ZR1 is the fastest production model ever offered by General Motors, with a top speed of 205 mph. A supercharged, hand-assembled 6.2L LS9 engine and suite of advanced performance technologies, including Performance Traction Management and Magnetic Selective Ride Control, are the elements behind the highest-performing Corvette in history.
Capability of the ZR1 is maximised with the available PDE performance package, which is highlighted by Michelin® Pilot® Sport Cup Zero Pressure tires. When combined with Performance Traction Management (PTM) technology – which manages torque delivery for maximum performance – the tires offer up to an 8-percent gain in maximum lateral acceleration, to 1.13g, and improved braking distance.
The PDE package’s effectiveness was demonstrated in 2012 with a new lap time of 7:19.63 around Germany’s legendary Nurburgring, which improved on the ZR1’s previous benchmark there by more than six seconds.
The new 60th Anniversary Design Package is available with the 3ZR trim and the content includes:
- Arctic White exterior
- Twilight Blue custom leather-wrapped interior with blue accent stitching
- Embossed and embroidered 60th Anniversary logos and a special steering wheel badge
- Suede accents on the steering wheel, shifter, parking brake handle, armrests and door panels
- Special wheel centre caps with the 60th Anniversary logo
- Gray-painted brake calipers
- Available Silver Blue Pearl stripe graphics.
Also new for 2013 are optional black-painted aluminium wheels and a pair of new exterior colours: Black – returning to the lineup – and Night Race Blue Metallic. And all 2013 Corvettes feature 60th Anniversary badges on the fascias, as well as 60th logos in the instrument panel gauge cluster and on the sill plates.
Customers who opt for the Corvette Engine Build Experience (option code PBC) can participate in the assembly of their engine at the General Motors Performance Build centre, in Wixom, Mich.
Corvette ZR1 design and exterior features
The Corvette ZR1’s fixed-roof body style optimises body rigidity and mass. Low weight is also the benefit of the wide, carbon-fibre front fenders – with ZR1-specific dual ports – carbon-fibre hood with a raised, polycarbonate window (offering a view of the intercooler below it), carbon-fibre roof panel, roof bow, front fascia splitter and rocker mouldings. The ZR1’s curb weight is 3,353 pounds / 1,521 kg (dry weight of 3,183 pounds / 1,444 kg).
The roof panel, roof bow, splitter and rocker mouldings feature a visible carbon-fibre weave that’s covered with a UV-resistant clear coat. The exterior also is distinguished with a full-width rear spoiler with raised outboard sections and four large, stainless steel exhaust outlets.
Additional features include:
- High-intensity discharge headlamps
- Contrasting headlamp housing colours are available in Blade Silver Metallic, Cyber Gray Metallic and Black
- Customer-selectable brake caliper colours offered in red, yellow, silver and gray (blue calipers are standard)
- Exterior colours: Arctic White, Blade Silver Metallic, Inferno Orange Metallic, Velocity Yellow Tintcoat, Torch Red,Supersonic Blue Metallic, Cyber Gray, Crystal Red Tintcoat, Black and Night Race Blue Metallic.
Twenty-spoke painted aluminium wheels – 19 x 10-inch in the front and 20 x 12-inch in the rear – are standard, with chrome-aluminium versions available. Also available are new black-painted aluminium wheels and the lightweight cup-style wheels that are part of the PDE ZR1 High Performance Package. Machined Cup wheels with gray pockets are available on any ZR1.
Corvette ZR1 interior
Corvette’s interior is inspired by the car’s dual-cockpit heritage. Seats that were introduced in 2012 deliver improved appearance, and larger bolsters on the seat back and cushion areas provide better driver support, especially in high-performance driving. Microfibre seat inserts are optional.

- An onboard navigation system with voice recognition is included with 3ZR. It features a 6.5-inch (165 mm) colour touch-screen display
- Head-up display is standard and includes Track Mode with g-meter
- Specific gauge cluster with boost gauge (also displayed on the head-up display) and 220-mph (370 km/h) speedometer readout.
A custom leather-wrapped interior package is standard on the 3ZR trim, featuring a leather-wrapped upper and lower instrument panel, door pads and seats; choice of exclusive colours: Dark Titanium, Ebony or Cashmere, with unique colour breakup; padded door panel armrests; “Corvette” embroidered on passenger-side dash pad and a unique centre trim plate with a gunmetal pattern.
Corvette ZR1 powertrain and drivetrain
The supercharged LS9 6.2L small-block engine is the power behind the ZR1’s performance. A sixth-generation Eaton supercharger helps the LS9 make big power and torque at lower rpm and carries it in a wide arc to 6,600 rpm, as it pushes enough air to help the engine maintain power through the upper levels of the rpm band – the area where supercharged performance tends to diminish. Heavy-duty and lightweight reciprocating components – including titanium connecting rods – enable the engine’s confident high-rpm performance.
The LS9 is hand-assembled at GM’s Performance Build centre in Wixom, Mich., and incorporates special processes typically seen in racing engines to produce a highly refined and precise product. For example, cast iron cylinder liners are inserted in the aluminium block and are finish-bored and honed with a deck plate installed. The deck plate simulates the pressure and minute dimensional variances applied to the block when the cylinder heads are installed. This ensures a higher degree of accuracy that promotes maximum cylinder head sealing, piston ring fit and overall engine performance.
Backing the LS9 is a six-speed manual transmission and a twin-disc clutch that provides exceptional clamping power, while maintaining an easy clutch pedal effort. ZR1-specific gearing in the transmission provides a steep first-gear ratio that helps launch the car, and top speed is achieved in sixth gear. The twin-disc clutch system employs a pair of discs, which spread out the engine’s torque load over a wider area. This enables tremendous clamping power when the clutch is engaged, while also helping to dissipate heat better and extend the life of the clutch.
The rear axle also is also unique to the ZR1 and features asymmetrical axle-shaft diameters – 33 mm on the right side and 40 mm on the left – that were developed after careful testing to provide optimal torque management. The axles are mounted on a more horizontal plane that correlates with the wider width of the rear wheels and tires.
Corvette ZR1 chassis and suspension
The ZR1 is built on an aluminium-intensive chassis and features an independent SLA front and rear suspensions, with aluminium upper and lower control arms. A magnesium cradle serves as the attachment point for the engine and some front suspension components. It is lighter than aluminium, yet incredibly strong, and helps improve the front-to-rear weight distribution, as do carbon-fibre front fenders and wheelhouses.
Magnetic Selective Ride Control is standard and tuned specifically for the ZR1. The system’s ability to deliver a compliant ride with nearly instantaneous damping adjustments enabled engineers to develop a surprisingly supple ride quality in a supercar that still delivers cornering grip of more than 1g.
From a high-performance perspective, Magnetic Selective Ride Control helps the rear axle remain planted during launch for smooth, hop-free acceleration. It also helps suppress axle movement when cornering on broken or uneven pavement.
Launch Control with Performance Traction Management (PTM) technology optimises traction for greater and more consistent on-track performance. PTM system holds a predetermined engine speed while the driver pushes the throttle to the floor. That allows the driver to quickly release the clutch and the system modulates engine torque 100 times per second to maximise the available traction. The system is capable of approaching a skilled driver’s best effort and repeats it consistently. PTM also integrates the ZR1’s traction control, active handling and selective ride control systems to enhance track driving consistency and overall performance. When full throttle is applied upon exiting a corner, it automatically manages acceleration dynamics.
Commensurate with the ZR1’s engine output is the braking system, headlined by Brembo carbon-ceramic brake rotors. Found on only a few exotics and more expensive supercars, carbon-ceramic brake rotors are made of a carbon-fibre-reinforced ceramic silicon carbide material. The advantages of these rotors are low mass and resistance to wear and heat. In fact, the rotors should never show corrosion or require replacement for the life of the vehicle, when used in normal driving.
The vented and cross-drilled rotors on the ZR1 measure 15.5 inches (394 mm) in diameter in the front and 15 inches (380 mm) in diameter in the rear – making them among the largest carbon-ceramic rotors available on any production vehicle.
Clamping down on the high-tech rotors are six-piston front calipers and four-piston rear calipers, each painted a ZR1-exclusive blue. The brakes are visible through the ZR1’s exclusive wheels: 20-spoke alloy rims that measure 19 x 10 inches in diameter in the front and 20 x 12 inches in the rear. A Sterling Silver paint finish is standard; chrome and black versions are optional. Machined Cup wheels with gray pockets are also available. The wheels are wrapped in Michelin Pilot Sport 2 tires developed specifically for the ZR1, measuring P285/30ZR19 in front and P335/25ZR20 in the rear.
The PDE High Performance Package features Michelin® Pilot® Sport Cup Zero Pressure tires, developed by the same Michelin engineers who developed tires for Corvette Racing in the American Le Mans Series and are essentially street-legal versions of a racing tire. The 285/30-19 (front) and 335/25-20 (rear) tires are matched with aluminium cup-style wheels. They are about five pounds lighter (2.2 kg) and stronger than the standard 20-spoke wheel.
Corvette ZR1 by the numbers
ZR1 models are distinguished from other Corvette models by their vehicle identification number, or VIN. Each carries a unique, identifying VIN digit, as well as a sequential build number. These identifiers make it easy to determine the build number of a specific car – information treasured by enthusiasts and collectors. For example, a ZR1 with a VIN ending in “0150” would indicate it is the 150th ZR1 built for the model year.
Corvette ZR1 safety and crash-avoidance features
Corvette ZR1 is designed to help drivers avoid crashes, while protecting the occupants in the event a crash occurs. A strong body structure is designed to absorb crash energy and provide a protective “safety cage” around occupants.
Additional safety features include:
- Four standard air bags include side-impact air bags, which provide head protection for outboard passengers in the event of a side-impact or rollover crash
- Active Handling electronic stability control system helps reduce the risk of rollover crashes by keeping the vehicle in the driver’s intended path by applying throttle, braking or a combination of both
- Standard four-wheel-disc brake system with anti-lock
- Pretensioners are standard. They minimise forward movement during a collision, while load-limiting retractors cinch the belt more tightly
- Tyre pressure monitoring system and run-flat tires are standard
- Standard remote keyless entry with push-button starting.
