The ultimate Camaro?

Chevrolet recently unveiled the Camaro ZL1 at the New York Auto Show but drivers looking for something even more extreme might want to wait for the Camaro Z/28 which was recently spotted undergoing testing on the Nürburgring.

Looking undeniably aggressive, the high-performance model has a ZL1-inspired front fascia with a “flow-tie” grille and large air intakes.  The car has also been equipped with an aerodynamic body kit that includes a front splitter, canards, and an adjustable rear wing.  Other notable highlights include aerodynamic side skirts, lightweight alloy wheels, and a four-tailpipe sports exhaust system.

Spy photographers couldn't get close enough to snap interior photos but the model is expected to have a flat-bottomed steering wheel, Recaro sport seats, and a unique shifter with suede upholstery.  The car could also incorporate a number of weight saving measures including a minimalistic audio system, lightweight rear seats, and an air conditioning system that is optional.

Performance specifications remain unclear but rumors have suggested the Camaro Z/28 will be powered by a new 3.6-liter biturbo V6 engine.  There's no word on specifications but the previous 7.0-liter V8 engine developed 505 horsepower and 481 pound-feet of torque.

Drivers can also expect an assortment of other performance features including a sport-tuned suspension, a limited-slip differential, and Brembo carbon-ceramic brakes - just to name a few.
