About the Ariel Atom 3.5 R
The Ariel Atom 3.5 R is a hardcore, limited-production evolution of the standard 3.5, designed to bridge the gap between the base models and the V8. It utilizes a Honda-sourced K20Z4 engine equipped with a high-boost supercharger and a side-mounted intercooler system housed in distinctive pods. The most significant mechanical upgrade is the Sadev six-speed sequential transmission, which allows for lightning-fast, full-throttle upshifts. With revised dampers and increased chassis rigidity, it offers one of the most visceral and direct driving experiences of any road-legal vehicle.
