GM ditches ALMS GT1 and moves to GT2 with latest ZR1-based racer.
The new racer features bodywork that closely resembles the ZR1 road car, including identical wheel arch dimensions, headlamps and the ZR1’s aluminium chassis – and even the road car’s tilt and slide steering column is carried over.
The new GT2 cars will run for the rest of the 2009 ALMS season with a 6.0 version of the GT1 racer’s 7.0 V8, but next year they’ll get an all-new 5.5 litre V8 based on the next generation of the Chevy/GM small block. The 2009 engines will be built alongside the production LSD engines used currently in the ZR1.
