Ariel Atom 4

This 2021 Ariel Atom 4 has covered just 4,965 miles across two owners, and arrives with the factory 350 bhp upgrade over the standard 316 bhp output — pushing the turbocharged 2.0-litre Honda-derived four-cylinder to its full rated potential. The headline numbers speak plainly: 2.8 seconds to 62 mph and 162 mph flat out, all from a car that weighs next to nothing thanks to its exposed titanium powder-coat tubular chassis.

The options list is extensive and well-chosen. Öhlins TTX 3-way adjustable inline remote-reservoir dampers replace the standard suspension, and AP Racing 4-pot calipers appear at both ends with cockpit-adjustable remote brake bias for track use. A 3-stage variable turbo boost controller, limited-slip differential, and uprated gearshift cable bushings round out the mechanical package. Green panels over black wheels is a purposeful visual combination, and the inclusion of a standalone fire extinguisher, front and rear towing eyes, and an outdoor cover signals an owner who thought carefully about how the car would be used.

At under 5,000 miles, this Atom 4 has barely been run in. The 350 bhp upgrade and Öhlins dampers make it one of the more serious configurations available in the used market — a car that functions equally well as a road weapon or a track-day tool.
