Cosworth Is Using a Wild Three-Cylinder Test Engine to Engineer Gordon Murray's New V-12

It's a scaled-down version of the V-12 that will power Murray's upcoming T.50 supercar.

Gordon Murray Automotive's upcoming T.50 is one of the most highly anticipated cars of this decade. Founder Gordon Murray—the genius behind the McLaren F1—promises it'll be the "last and the greatest analog supercar ever built." Cosworth has been recruited to develop the naturally aspirated V-12 engine, and it's built a scaled-down three-cylinder mule for some initial testing. It sounds fantastic.

According to the video above, the Cosworth-built V-12 set to power the T.50 will displace 3.9 liters, using a dry sump lubrication system and dual overhead cams. The finished product should be able to rev past 12,000 rpm. This three-cylinder version of the motor was built to ensure the parts could handle the revs, and that the engine would pass emissions testing.

Gordon Murray Automotive promises the engine will make 650 horsepower and 332 lb-ft of torque. Those aren't crazy numbers in today's world of four-digit-horsepower supercars, but it's important to consider another thing: weight. The company says its car will weigh just 2160 pounds—around the same as a first-gen Mazda MX-5 Miata. Pair that insane power-to-weight ratio to a manual transmission and a center seating position, and you've got yourself a recipe for fun. And that's before you factor in the massive downforce-inducing fan mounted out back.
