The Ariel Atom 4 test car has an adjustable Ohlins suspension that was initially set fairly permissively for compression and rebound damping. However, with some experimentation, it is evident that this car remains dynamic and characterful even when the dials are cranked up. It has a tendency to move around on its suspension springs, requiring the driver to manipulate its weight similar to a sports bike or an old Porsche 911.

This process of understanding the Atom’s rearward weight bias and its lively behavior over bumps can be developed on the road. However, the real thrill comes when driving it on the track, where it becomes incredibly absorbing and vivid.

The firmer and more focused the Atom is, the less noticeable this characteristic becomes. A 4R with a road/track spring setup or even the full track springs offers tight control with minimal roll. Although the steering still provides weight and feedback, the driver has less concern about body movements when sliding. Overall, it is a well-balanced track car.

COMFORT AND ISOLATION

Despite the Atom’s hardcore ethos, even with the Ohlins dampers set to a more track-biased configuration, it displays a surprising level of compliance in its primary ride. It handles undulating surfaces smoothly and effectively absorbs sharp compressions without compromising its excellent body control.

However, the Atom is not a relaxing car to drive, especially during touring. Due to its size and liveliness, the driver remains highly aware of imperfections in the road surface that can be felt through the open wheels. Fortunately, these issues are most noticeable at low speeds and over severe bumps. In general, the car tracks straight and does not feel overly sensitive compared to its peers.

The Atom’s open design leaves the driver quite exposed to the elements, making it physically demanding. There is no heater, so warmth depends solely on the weather and the driver’s clothing. At motorway speeds, effort is required to keep one’s head steady in the wind, contributing to fatigue.

Moreover, the noise inside the Atom is quite high. At idle, it measures at 74dB, which increases to 92dB at a 70mph cruise. This level of noise requires earplugs or a helmet for better refinement.

The seats are initially comfortable, although they can become unforgiving over long distances. Most testers agree that the seats do a good job of holding the driver in place, but some noted a lack of lower back support. Generally, spending more than an hour in an Atom without a break might not be ideal, but most owners do not plan for extended drives anyway. Treating it like a superbike would be a suitable approach.
