# Gordon Murray’s New V12 Now Makes 672 Horsepower

Cosworth already began testing [Gordon Murray Automotive's brand new 3.9-liter V12](<https://www.thedrive.com/news/34968/gordon-murrays-new-v12-is-real-and-heres-what-it-sounds-like>), a mechanical marvel that astoundingly weighs under 400 pounds. We heard it fire up for the first time Monday, and soon, it'll be [screeching to 12,100 rpm](<https://www.thedrive.com/accelerator/32719/listen-to-gordon-murrays-t-50-prototype-engine-sing-its-12k-rpm-song>) with no turbos or superchargers holding it back. In short, it's exactly what you'd expect from the genius behind McLaren's almighty F1.

Powering the limited edition [GMA T.50 supercar](<https://www.thedrive.com/news/31421/gordon-murrays-mclaren-f1-successor-launches-in-may-with-aero-work-by-f1-team>), this twelve-cylinder features aluminum pistons, titanium valves and conrods, an ultra-short crankshaft, gear-driven cam drive and a crank-driven 48-volt generator starter mounted at the rear of the engine, so the car doesn't need a regular alternator. One less horsepower-sucking belt to worry about while GMA saves 46 pounds.

The engine was built specifically for the T.50 and was initially rated at around 650 horsepower. However, [*Autocar* reports](<https://www.autocar.co.uk/car-news/new-cars/murray-t50-hypercar-reaches-v12-production-milestone>) that the latest tests revealed not only that the GMA engine will pass all emission regulations without much fiddling, but also that it will produce at least 672 horsepower at a spine-tingling 11,500 rpm.

**GMA**

While the whole dry-sump V12 is just 16.1-inches tall, its shortened crankshaft sits only 3.34-inches above the bottom. With such lightweight internals, Gordon Murray says the naturally aspirated Cosworth-GMA 3.9 will have a throttle response almost three-times as quick as BMW Motorsport's S70/2, the 6.1-liter V12 powering the McLaren F1.

Send those 672 horses and 332 pound-feet of torque through Xtrac's new six-speed manual also built specifically for Gordon Murray's project, and you're in for a ride you won't get from any other carmaker.

Personally, my car could benefit from [their three-cylinder version](<https://www.youtube.com/watch?v=Zt8EX1VOmSc>) used for testing prior to the real deal being ready. Cosworth, my contact details are on this website.
