A 668 kg Ariel Atom just battered a Porsche 911 GT2 RS's lap record on road tyres

The 525 hp Atom 4RR lapped Anglesey nearly 2 seconds quicker than the mighty Manthey 911 GT2 RS, proving once again that lightness beats brute force.

Proof, again, that weight is the enemy and lightness is king

Here is your reminder that in the battle between power and weight, weight usually wins. The featherweight Ariel Atom 4RR has smashed the Porsche 911 GT2 RS's lap record at Anglesey, and it did so on road-legal tyres, in full road trim, for a fraction of what a fettled Porsche costs. It is the kind of giant-killing result that makes us grin from ear to ear.

The record run

At Anglesey Circuit in Wales, Ariel test driver Phil Keen lapped the Atom 4RR in 1:27.77. The previous benchmark, held by a Porsche 911 GT2 RS fitted with the fearsome Manthey performance kit, stood at 1:29.35, so the little Ariel was nearly two full seconds quicker. The really telling part is that the Atom was in full road trim on road-legal Yokohama A052 tyres, not a stripped-out, slick-shod special.

Tiny weight, huge power

The Atom 4RR's secret is the oldest one in the book: mass, or the lack of it. It tips the scales at just 668 kg, yet packs a 2.0-litre turbocharged Honda Civic Type R four-cylinder tuned to a savage 525 hp, well up on the road car's 315 hp. That gives it a power-to-weight ratio most hypercars can only dream of, and on a tight, technical circuit like Anglesey that combination is simply devastating. It is the same lightweight-is-everything philosophy that makes the fan-powered McMurtry Speirling such a track weapon.

Cheaper than the car it beat

Then there is the price. The Atom 4RR starts at around 208,000 pounds, which is a lot for an Ariel given a standard Atom 4 costs from 48,000 pounds, but it is still well below what a Manthey-fettled 911 GT2 RS commands, hence the many-headlines about it doing the job for a fraction of the money. It shames far pricier and more powerful machinery, including Porsche's own hardcore track cars like the 911 GT4 R customer racer. The 4RR will be built in very limited numbers and is set to appear at the Goodwood Festival of Speed later this year.

AutoNext Take

We love this so much. In an age of two-tonne, thousand-horsepower everything, a skeletal British machine humbling a Manthey Porsche on ordinary road tyres is a glorious reality check. The Atom 4RR is not cheap in absolute terms, but as a distilled, no-nonsense driving tool it is worth every penny, and it proves the lightweight gospel that Colin Chapman preached decades ago still holds true. Records set on slicks are impressive; a record set in road trim, on road tyres, is something else entirely. More lightness, less bloat, please. This is our kind of car.

Wanting a manual gearbox does not make you a dinosaur, it makes you honest about why you drive

The manual gearbox is worth keeping, and not out of nostalgia. It remains the one mechanical link between a driver's intent and the car's behaviour that neither automation nor electrification has replaced, and that is reason enough to defend it. Automatics have already won on speed, efficiency and safety, but none of that was ever the whole argument for driving in the first place.

Ford's new Le Mans hypercar just fired up its V8, and it sounds glorious

Ford has fired up the engine of its new top-class Le Mans Hypercar for the first time, choosing 4 July, America's 250th Independence Day, to do it. The car uses a naturally aspirated 5.4-litre V8 derived from the Mustang Dark Horse R, GT4 and GT3 programmes, paired with a hybrid system. On-track testing starts in August 2026, ahead of a full FIA WEC campaign and a 2027 24 Hours of Le Mans debut, where Ford joins Ferrari, Toyota, BMW, Cadillac and more.
