I found this race that I thought was very interesting because it has a stock 2007 BMW 325i racing against a stock 2007 Audi A4 2.0T on an airport runway. What I like about this race is that it highlights both cars strengths. The Audi does better on the launch but the BMW catches up when they reach highway speeds.
Here is the video:
