The exhaust sound is good on the Porsche Macan GTS with pops and crackles, and better than the BMW, but the AMG is the worst. From the standing quarter-mile, the BMW wins the race with the best launch, and the Mercedes-AMG, who had a bad start, comes in second. In the final race, the BMW X3 M50 won. The BMW X3 M50 took the quarter-mile in 12.7 seconds, the Porsche in 12.8 seconds, and the Mercedes-AMG in 12.9 seconds. In the 50 mph rolling race, the Porsche went ahead with more power, the driver of the BWM thought that his car had more power, and one tester was impressed with the stop from the Mercedes in the 100 mph brake test. The BMW had poor brakes overall.
