The base price for a 2015 Audi R8 4.2 is $119,150. The model used in this drag race was using a 6-speed manual transmission.
After four years in development, the new M3 and M4 graduated with BMW’s latest turbocharged engine, a 3.0 liter six-cylinder unit that has replaced the fans’ darling, V8 naturally aspirated powerplant.
Even though it offers less cylinders and a smaller displacement, 4.0L V8 vs 3.0L straight-six, the new engine and its two turbochargers give it even more oomph than before, while reducing emissions and increasing fuel economy. The torque also sees a significant hike, 110lb ft to 405lb ft between 1850rpm and 5500rpm.
For this test, the M3 owner brought to the fight the 7-speed DCT.
Both cars weigh around 3,300 lbs.
