Yesterday, we gave you a sneak peek at GM’s new X-cars – track-prepared Corvettes and Camaros that bridge the gap between street-driven vehicles and purpose-built racecars. Today, we can show you all the details of these two drool-worthy concept vehicles.

The Z06X starts life as a production Z06 with the 1LZ equipment package, the Z07 performance package, and the CFZ carbon fiber package. It’s the lightest production Corvette setup, and has carbon ceramic brakes, magnetic ride control, and aero enhancements including a front splitter. The X concept adds a carbon fiber rear wing, polycarbonate rear window, coil-over struts with camber plates, plus safety items including a cage, racing seat, harnesses, and a fire suppression system. Chevrolet teamed with Pratt and Miller, partners in Corvette Racing in the American LeMans Series, to create this Z06X track car concept.

Power is from the tried and true LS7, but removal of sound deadening material, carpeting, and the stereo offset the weight gain from the added safety equipment, keeping straight-line performance much the same as the road-going Z06.

VEHICLE HIGHLIGHTS

The SSX concept car was constructed with input from Pratt and Miller as well, and Riley Technologies using parts proven in the Grand Am racing series. Emphasis was placed on weight reduction, with carbon fiber body panels and the elimination of the majority of sound deadening materials, removal of the carpet, and a rear seat delete. The SSX gets safety and track-prep enhancements similar to those on the Z06X,  as well as carbon fiber aero parts like the adjustable rear wing and front splitter, a revised lower grille, and unique brake cooling ducts.

Unlike the Z06X, which makes due with “only” the stock LS7, the SSX gets some significant work to the production LS3 powerplant, with a revised cam, upgraded heads, and a dry-sump oiling system.

VEHICLE HIGHLIGHTS

  • Production six-speed manual transmission with Corvette ZR1 twin-disc clutch
  • Low-restriction air induction and exhaust systems
  • Four-wheel disc racing brake system with six-piston front/four-piston rear calipers and drilled and slotted rotors

Both cars are currently just concepts, albeit very complete and well-thought-out ones, rather than something you could go out and buy tomorrow. But who knows? If the reaction is positive enough, perhaps Chevy can be persuaded to add the SSX and Z06X to the GM Performance Parts catalog as turnkey race cars.
