In contrast to modern electric supercars like the Lotus Evija and Rimac Nevara, the Gordon Murray T.50 is gloriously old-school in all the right ways. Built by the man who designed the legendary McLaren F1, the T.50 is the ultimate analog supercar. At its heart is a 3.9-liter naturally-aspirated V12 that produces 650 horsepower and revs all the way up to 12,000 rpm - even higher than the Aston Martin Valkyrie. Since the T.50 was announced, Gordon Murray has been chronicling the car's development in a series of interesting behind-the-scenes videos.

Last week, three-time Indy 500 champion Dario Franchitti, who is helping develop the T.50, had a blast behind the wheel of a T.50 test mule known as "George."

In the above video, we get to see Franchitti thrash a T.50 XP prototype around the UK's Millbrook Proving Ground. While we got to hear the V12 in all its 12,000 rpm glory in George, it's limited to 6,000 rpm in the XP, though it still sounds glorious. Since the T.50 XP is more representative of the production model, Franchitti jokes that it's "a bit more sophisticated" than the George test mule.

Like the McLaren Speedtail, the T.50 has a central driving position mimicking that of the McLaren F1. This layout gets Franchitti's seal of approval. "It just feels right", he said while sat inside the cockpit.

"You just think, 'Why did nobody do this?' Everything else feels like a compromise. You jump in any other car, and it's a compromise." Franchitti is clearly smitten, but he's still "thinking about bits and pieces and how to make it better." After the test drive, Franchitti was shaking with adrenaline after experiencing the T.50's V12, even at 6,000 rpm.

With more supercar manufacturers switching to electrification, the T.50 could be among the last of its kind. "If that's the full stop of the internal combustion engine, it's a pretty good full stop." To remind us how great it sounds, we get to hear Franchitti fire it up one last time before a trio of T.50 prototypes attack the proving ground in the final shot.

This weekend, the Gordon Murray Automotive T.50 will make its public debut at the 78th Goodwood Members Meeting. Production of the T.50 is limited to just 100 examples, while the track-only T.50s Niki Lauda is restricted to 25 units.
