Audi R18 Tdi

Audi's digital rearview mirror is officially going from the Le Mans clobbering, race-only Audi R18 to the road-going R8 e-tron (click the image above to enlarge). Lacking a rear window put the R8 e-tron in the same rear-view challenged category as its racing brethren, and so has been provided the same solution.

Every year at every auto show we see concept cars that envision replacing the rearview mirrors with digital cameras. They're usually the exterior mirrors and not the central one above the windshield, but whatever the case, and however much sense they seem to make, government regulations prevent them from being put into production. But Audi has found another use for the idea: its racing cars.

The diesel era at Le Mans may not be over yet, but already we're seeing the emergence of a new propulsion trend: hybrids. Toyota recently announced the TS030 Hybrid LMP1, Peugeot was working on a hybrid version of its 908 prototype before it killed the race program, and now Audi has confirmed a hybrid version of the R18 TDI.

After dominating Le Mans-class endurance sportscar racing for years now, Audi is left with little to prove. Plus, with sister-company Porsche returning with an LMP1 program of its own, and Bentley reportedly considering the same, rumors have been circulating that the four-ringed automaker could quit while it's ahead. It's something that rivals old (like Peugeot) and new (like Toyota) were undoubtedly rooting for, but no such luck: Audi isn't going anywhere but the finish line.
