ARIEL ATOM 4

Vehicle Description

There aren’t many cars that make 350bhp sound like a frightening amount of power, but when you have virtually nothing surrounding you and very little weight to move, it certainly is! This Atom 4 has all the right upgrades, just 9,000 miles and has been maintained exclusively by Ariel.

Performance & Specification

At the heart of the car is the factory 350bhp power upgrade with three-stage boost control. The ability to change the boost gives the car different personalities, but with everything turned up the performance is simply savage.

Just as importantly, this example has the desirable brake bias adjustment, allowing the braking balance to be tailored to the driver and conditions.

Factory specification and upgrades include:

Factory 350bhp power upgrade
Three-stage boost control
Brake bias adjustment
Full carbon headlights
Ariel upgraded gearbox linkage

The gearbox linkage was upgraded by Ariel in August 2025, further sharpening what is already one of the most involving manual gearboxes around.

History & Maintenance

This 3-owner, 9,000-mile example has a Full Ariel Service History and has only ever been worked on by Ariel.

Its latest comprehensive service was completed on 28th July 2026, when Ariel also installed the latest engine map. The invoice came to nearly £1,000, and Ariel commented on just how well presented and sorted the car was.

All Ariel invoices, paperwork and service history accompany the car, and the MOT runs until June 2027.

Extras

Also included are a pair of nearly-new Avon front tyres, now becoming very difficult to source, a genuine Ariel fitted cover (£450+), MagLock charging phone mount with iPhone 16 charging case and a professionally installed trickle-charger connection accessible from the driver's seat.

The car also comes with the driver-side cushion set, costing approximately £400.

Summary

An Atom is about removing everything between you and the act of driving. With 350bhp, three-stage boost control and adjustable brake bias, this one takes that philosophy even further.

Beautifully maintained, properly upgraded and backed by
