Although it looks rather similar to the previous version, Ariel claims the Atom 4 really is all-new. In fact, the British automaker claims that only the clutch pedal, brake pedal and fuel cap on the latest version of its track-focused sportscar, which will be officially launched at the Goodwood Festival of Speed, have been carried over to the new car.

More importantly, though, is the fact that the Ariel Atom 4 is now powered by Honda's turbocharged 2,0-litre four-cylinder engine (yes, the K20C from the Civic Type R), which has been placed on the rear axle. In the Atom, this unit (mated to a six-speed manual) has been tuned to deliver 239 kW and 420 N.m of torque which, together with its overall mass of 595 kg, facilitates a claimed 0-100 km/h time of just 2,8 seconds (and a 0-160 km/h dash of 6,8 seconds), with a top speed of 261 km/h.

The new hand-welded tubular chassis surrounds the driver and passenger, who are each snug in a special composite seat. Double wishbone front and rear suspension with adjustable rod ends, toe angles, pushrods and fixed Bilstein dampers is also included. Braking is taken care of by a set of 278 mm front ventilated and 253 mm rear solid discs.

Of course, there’s not much going on in the cabin other than a TFT dash cluster that provides all of the necessary readings, and a four-point harness.

The new Atom will be produced at the brand's factory near Crewkerne in England. Expect to see around 100 units produced every year alongside the Nomad and Ace. To assist with production, the Ariel Atom 4 will also be produced under license by Ariel North America in Boston.
