2021 Ariel Atom 4

An Ariel Atom 4 with the desirable 350 bhp upgrade, Öhlins TTX remote-reservoir dampers, and a titanium-finished chassis — this is about as far from a base-spec Atom as you can get without commissioning a one-off. Finished in green panels over the titanium powder-coated frame, it pairs the Honda-derived turbocharged 2.0-litre four with a six-speed manual gearbox and limited-slip differential, making it one of the more involving configurations available.

With just 4,965 miles covered across two owners from new, the car has barely been used relative to its five years on the road. The specification sheet reads like a track-day wish list: AP Racing four-pot calipers front and rear, cockpit-adjustable brake bias, quick-release steering wheel, uprated gear shift cable bushings, and both front and rear towing eyes for circuit use. The high-performance cooling package and baffled oil sump suggest it was ordered with sustained hard driving in mind. Stainless steel brake and clutch lines, a stand-alone fire extinguisher, and a three-stage variable boost controller round out a comprehensively optioned example.

Registered on a 71 plate, this 2021 car represents the current-generation Atom 4 platform with its fully redesigned chassis and improved aerodynamics over earlier models. At under 5,000 miles with this level of specification, well-optioned Atom 4s in this condition rarely come to market.
