This is What Singer’s New 500 HP air-cooled Engine Sounds Like

The latest 991.2 GT3 produces 500 horsepower. Indeed, so did the 911R. Those cars have more than two decades worth of development on the base engine used for Singer’s latest creation, yet their latest air-cooled flat-six matches that output. Of course, the Singer powerplant was developed by some of the most important names in the automotive world. No less than Williams Advanced Engineering and Hans Mezger himself were involved in making this 9,000RPM, 24-valve engine happen.

While we toss around Mr. Mezger’s name here quite often, Williams is less involved in the Porsche world. Here’s a gentle reminder of their CV before we give the new engine a listen.

• 9 Time Formula 1 Constructor’s Championship Winners (Winning percentage since 1978 – 23.1%)
• 7 Time Formula 1 Driver’s Championship Winners (Winning Percentage since 1977 – 17.9%)
• 114 total Formula 1 Victories
• Developed the MG Metro 6R4 Group B car, as well as the Renault Clio Williams hot hatch
• Developed the hybrid power system for the Porsche 911 GT3 R Hybrid

With that in mind, listen to the new engine:

What an absolute screamer. This car had better be eligible for an appearance at Soundnacht in coming years, because it is an absolute treat to listen to.

What we can see of the new car also looks promising. The new engine inhales through ram-air intakes which take the place of the rear quarter windows. Those intakes feed into a carbon fiber airbox, which is itself connected to carbon fiber intake trumpets. The wide body package is also interesting, and combines a bit of 934 with a lot of not-yet-backdated 964. While the finished car will surely have a more vintage look, even in its incomplete state this is still a very visually appealing car, and an incredible achievement for Williams and Singer.

Now, how much for a 300 horsepower, 2.9L, short stroke 944 16v engine, Williams?
