Acura has published the first picture of a NSX prototype undergoing testing. The sports car debuted at the North American International Auto Show earlier this year. While the picture isn't of the highest quality, it suggests the production model will have new headlights, larger mirrors and restyled air intakes.

The pre-production prototype will be shown at the Mid-Ohio Indy 200 on August 4th. Acura is seeking to get maximum publicity out of the event, so the car will lap the circuit live on NBC.

The NSX will be produced at Acura's Performance Manufacturing Center in Ohio. It will be powered by a mid-mounted V6 engine and a Sport Hybrid Super Handling All Wheel Drive (SH-AWD) system that has 2 electric motors that power the front wheels as well as another motor that is integrated into the dual-clutch transmission.
