Those with a passion for torque were disappointed when it became clear that Audi was unlikely to ever build a production version of the R8 V12 TDI that was shown at the 2008 Detroit Auto Show. Now the automaker has come back with a new R8-based concept that puts the diesel to shame. The new e-tron packs four electric motors and a lithium-ion battery pack with a fairly tame-sounding 313 hp but an insane 3,319 lb-ft of torque. The run to 62 mph takes 4.8 seconds, but rolling acceleration from 37-75 mph takes just 4.1 seconds thanks to the e-tron's massive amount of twist.
While acknowledging that electric vehicles are still far from economically viable volume production vehicles, Audi is nonetheless working on electric technology, both for hybrids and pure EVs. The pack sports a 53kWh capacity of which 42.4 kWh is usable. The pack weighs in at 1,036 pounds out of a total vehicle weight of 3,527 pounds and is mounted ahead of the rear axle and liquid cooled. Each of the axles sports two electric motors allowing the e-tron to retain Audi's signature quattro all-wheel drive. The e-tron has an estimated range of 154 miles on the EU combined driving cycle and you can read more about it in Audi's official press release after the jump.
