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.

      As a kid in the 70s, we owned a Mazda RX-2 - sadly, as thirsty as a sailor after 6 months at see, as unreliable as a Fiat in a rainstorm, but what sound, what power! Amazing car. Wish the Wankel programme all the best

      I'd have to agree, those 4 rotor engines are some of the best sounding in the world. Absolutely magnificent.

      While the gearhead in me totally respects the engineering, the car audio geek in me chuckles at their awe of this 'loud' vehicle.. I'd have said a Top Fuel car was indeed louder, but neither have anything on a top level purpose built car audio SPL vehicle. The world record stands at over 180 dB. So loud that a conventional microphone could no longer handle the vibration and pressure these systems produce - the reference measurement system actually uses a premium MAP sensor and a high-end DAC to take highly accurate measurements. So accurate in fact that NASA bought one of these systems to record how loud the space shuttle is at launch. Still, cool car and credit to the Forza team for their efforts!!!!

      Not to jinx it, but I'm grateful for a lack of Forza Haters in the comments. This is just a gorgeous sound.

      Forza 4.. Best game ever. You guys talking **** about the car sounds, at least they don't sound like vaccum's in Gran Turismo.. Drive a fully built subaru or honda tell me it doesn't sound real

      It would have been nice to see more of the actual process but a great peek into some interesting technology. That being said if you ever heard the Downing GTP lights car (yes, I am old enough to have seen them run in their day) the sound is mind numbing when the car is at speed. They actually don't sound terribly sophisticated in spite of the incredible engineering.

      right... so they are talking a lot about how load this car is... but is there a dB rating for the "loudest car ever"?

      This game is best experienced with surround sound, the sounds in FM4 are insanely realistic, dunno what these guys are bitching about. Unless they are hearing it in mono. Lol

      I like the sound of the old Ferrari from last month's DLC... the 312 Racecar? I love the V8's and big displacement engines overall, but there are some exceptions soundwise in Forza4. I look forward to driving the 787.

      I love Forza 4 but I CANNOT STAND the way the Ferrari 458 is shamelessly plugged in the game, much as I actually love the 458. "9.7" speed?! Really?! C'mon Turn10, fix it!
