The Goodwood Festival of Speed was spectacular this year. There are far too many incredible runs up the famous driveway to mention, but one stood out above the rest. We're talking about the McMurtry Speirling's crazy record-breaking 39.08-second run.

It must have been McMurtry's plan all along as, shortly after the record-breaking run, McMurtry's managing director, Thomas Yates, confirmed to Autocar that a road-legal version would go on sale. "Production will be limited to only a handful of units, and these will cost at least £1 million," said Yates. "We want to provide something that you can drive through the center of London, and then take onto a track," he said.

At the current exchange rate, that works out to $1.22 million. That's a large chunk of change, but consider that this single-seater will humiliate a Ferrari Monza SP1.

The good news is that the road-legal version will get the same powertrain as the track car. That means a claimed power-to-weight ratio of 1,000 bhp per tonne. To put that in context, the Speirling (thunderstorm in old Irish) weighs less than a Miata - its exact weight is unconfirmed, but is expected to be less than 2,204 lbs - but it has nearly 1,000 horses delivered nearly instantaneously courtesy of two electric motors powering the rear axle.

The big question is whether the famous Gordon Murray T.50-like downforce fans will be part of the road-legal package? We're happy to report the answer is yes, but owners will only be able to activate it in track mode. That's probably a good idea given how potent this car is.

Making it road-legal will take some time, however. McMurtry has to tone down the aerodynamics and add basic everyday things like headlights, wipers, and a rearview camera. If it will be sold in the USA, it will likely require a lot more.

Yates also confirmed that it's working on its next car, which will be even smaller. "So the future is smaller. For this car, the objective was to deliver something that was in no way wasteful, had no redundant space, and nothing was wasted, just a phenomenal, compact, lightweight driving experience," said Yates.

"Everyone always asks if we will be building a two-seater, but there are so many two-seaters to choose from, but for now, we are making amazing cars without that redundant space."

We expect to see great things from McMurtry because its heart is in the right place. It's following the Colin Chapman recipe of making a car as light as possible with no unnecessary flamboyance.

One also can't help but love an underdog. The previous Goodwood record was held by the famous VW ID. R. Volkswagen poured millions into designing the ID. R was designed specifically to break records and build the ID brand reputation.

And along comes a small, mostly unheard of McMurtry, named after its Irish founder, and it takes on and wins the giant conglomerate.
