On this episode of Head 2 Head, Motor Trend senior features editor Jonny Lieberman puts the Audi S8 and BMW 7 Series-based Alpina B7 to the test to find out which German executive rocket sled is best.
Lieberman starts out by comparing the B7 and the S8 on the track. While on paper 4.4-liter twin-turbo V’8′s 540 hp and 538 lb-ft of torque of the B7 far outclasses the 512 hp and 479 lb-ft the all-wheel drive S8′s 4.0-liter twin-turbo V-8 produces, the Audi destroyed the Alpina in a straight line, needing 3.5 second to hit 60 mph from a standstill, as opposed to the B7′s 4.3 second run.
Thinking something fishy was going on, Lieberman takes both flagships on a date to the dyno to see just how much horsepower each car was making, before heading out for a canyon run. The results of the tests were definitely interesting.
