In the Forza Motorsport 4 vs. Gran Turismo 5 debate, no one questions Forza's commitment to genuine engine noise. Normally, the Turn 10 sound engineers use Dyno Authority in a business and residential area of Seattle to record their cars' sounds, but when it came to the 1991 Mazda 787B that was unleashed in February's ALMS DLC, the Le Mans-winning racer was just too loud.

In fact, the 700-horsepower 2.7-liter Wankel-engined legend with four rotors and its continuously variable intake was the loudest car that Forza engineers have ever caught on mic. Look below to watch a video on how they did it.
