All emphasis for 2009 Corvette went into developing the ZR1 Corvette. Listed below is what distinguish's the ZR1 from the other models. • All-new LS9 supercharged 6.2L V-8 638 horsepower, 604 lb.-ft. of torque Dry-sump engine lubrication system same as Z06. • Titanium connecting rods. • Main bearing caps made of forged steel. • Supercharger Eaton R2300, four-lobe "Roots" type (2.3L) Maximum boost pressure 10.5 psi. • Crankshaft material is forged steel. • Piston oil-spray cooling; direct-mount ignition coils; 11-rib accessory drive. • Forged aluminum 9.1:1 pistons. • Upgraded Six-speed, close-ratio, race-hardened manual transmission. • New, high-capacity dual-disc clutch with 260mm plates compared to Z06 290mm. This reduced inertia and allows faster engine response and less drivetrain loss. • Unique ZR1 vehicle identification number sequence, the last 4 digits designate the build sequence for that year. • Higher-capacity and specific-diameter axle half-shafts; asymmetrical axle-shaft diameters – 33 mm on the right side and 40 mm on the left, enhanced torque tube construction. • Specific suspension tuning provides more than 1g cornering grip. • Twenty-spoke 19-inch front and 20-inch rear wheels. • Michelin Pilot Sport 2 tires – P285/30ZR19 in front and P335/25ZR20 in the rear – developed specifically for the ZR1. • Standard Brembo carbon-ceramic, drilled disc brake rotors –15.5-inch-diameter (394-mm) in the front and 15-inch-diameter (380-mm) in the rear. • Larger blue-painted brake calipers with substantially increased pad area. • Aluminum body structure with one-piece hydroformed perimeter rails frame and magnesium engine cradle same as Z06. • Standard Magnetic Selective Ride Control with track-level suspension. • Wider, carbon-fiber front fenders with ZR1-specific dual vents. • Carbon-fiber hood with a raised, polycarbonate window – offering a view of the intercooler below it. • Carbon-fiber roof panel, roof bow, front fascia splitter and rocker moldings with clear-coated, exposed carbon-fiber weave. • ZR1-specific full-width rear spoiler with raised outboard sections. • 220-mph Specific gauge cluster with boost gauge (also displayed on the head-up display) and (370 km/h) speedometer readout. • Curb weight of 3,324 pounds. • Top speed of 205 mph (330 km/h). • Seats, sill plates and gauge cluster with the ZR1 logo. |
