Chevrolet Camaro ZL1 revealed

Chevrolet has revealed the Camaro ZL1 at the 2011 Chicago Auto Show. As the most powerful factory Camaro to see the light of day, the American muscle car borrows the Eaton-supercharged 6.2-litre V8 from the Cadillac CTS-V.

With 550bhp on tap, the steroidal Camaro features heat resistant aluminium-alloy cylinder heads, and high strength pistons. Handling the extra power is a beefed up six-speed manual ‘box with a higher torque capacity, whilst a twin-disc clutch and dual-mass flywheel have been developed to make the shift action manageable.

Brakes are suitably uprated to cope with the power increase, 370mm front discs gripped by Brembo six-pot calipers, and 365mm discs with four-pot calipers at the rear.
