New Michelin Cup ZP tires for 2012 Corvette Z06/ZR1

Corvette’s greater performance for 2012 begins with the new, optional Michelin® Pilot® Sport Cup Zero Pressure tires, which are available on the two highest-performing models, the lightweight, 505-hp (377 kW) Z06 and the maximum-performance, 638-hp (476 kW) supercharged ZR1. They are competition-oriented tires, optimized for warm, dry conditions to increase cornering and handling capability. When combined with the Corvette’s exclusive Performance Traction Management (PTM) technology – which manages torque delivery for maximum performance – the tires are expected to help set new benchmarks for Corvette performance. Engineers estimate an 8-percent gain in maximum lateral acceleration, to more than 1.1g, and improved braking distance. Testing at Virginia International Raceway has demonstrated improvement of approximately three seconds per lap.

The Cup ZP tires were developed by the same Michelin engineers who develop tires for Corvette Racing in the American Le Mans Series and are essentially street-legal versions of a racing tire. They are included in the optional Z07 performance package on the Corvette Z06 and a new PDE performance package on the ZR1. The 285/30-19 (front) and 335/25-20 (rear) tires are matched with all-new aluminum Cup-style wheels in satin black or machined finishes. They are about five pounds lighter (2.2 kg) and stronger than the 20-spoke wheel offered in 2011. Performance Traction Management (offered on the Z06 for the first time in 2012) is an advanced system that optimizes traction for greater and more consistent on-track performance. The system also integrates traction control, active handling and selective ride control systems to enhance race track driving consistency and overall performance. When full throttle is applied upon exiting a corner, it automatically manages acceleration dynamics.

A full-width racing-style spoiler for improved aerodynamics is also included in both the ’12 Z07 and PDE packages. The Z06 model will now offer Magnetic Selective Ride Control, the world’s fastest-reacting suspension technology – an innovation Corvette pioneered several years ago. And as before, Brembo carbon ceramic brakes will be a part of the Z07 chassis package (they are standard on ZR1). Michelin Pilot Sport 2 tires remain standard on the ZR1. A carbon fiber hood will be an available option on 2012 Z06 models, while the standard manual transmission for ZR1 will include taller gearing in fifth and sixth gears, for a 2-mpg improvement in highway fuel economy.
