Ariel Atom 4RR marks its 25-year anniversary by unleashing a powered-up version, boasting an impressive 525 horsepower.
The Ariel Atom 4RR, a limited-edition, track-focused model, marks the most powerful variant yet of the lightweight two-seater sports car. As Ariel Atom marks its 25th anniversary, the Atom 4RR showcases a significant leap in power and technology.
The Atom 4RR's engine is a heavily reworked, turbocharged 2.0-litre four-cylinder Honda engine, boasting an impressive 525 hp (392 kW) and 407 lb-ft (550 Nm) of torque. This makes it more powerful than the previous Atom V8 from 2010 and about 125 hp more than the Atom 4R it’s based on.
Weighing in at approximately 1,543 pounds (700 kg), the Atom 4RR's power-to-weight ratio is estimated to be roughly 0.75 hp per pound (1,100 hp/tonne), placing it firmly in the hypercar territory in terms of performance. This lightweight vehicle is expected to deliver hypercar-level straight-line speed and track performance.
The Atom 4RR remains true to Ariel's minimalist and lightweight ethos, featuring the radical open chassis design that provides an unfiltered and raw driving experience tailored for dedicated circuit drivers.
Comparatively, the Bugatti Chiron, a hypercar known for its 1,479 hp quad-turbo W16 engine and weight of around 1,996 kg (4400 lbs), offers a vastly different driving experience despite some comparable performance metrics. While the Chiron is a technological and luxury benchmark with insane speed, the Ariel Atom 4RR delivers a raw, lightweight, track-focused driving experience with a similar or better power-to-weight ratio but without luxury creature comforts.
The Atom 4RR's production will be capped at 25 examples, each built to order. A finalised technical specification for the Atom 4RR will be confirmed by Ariel later this year. Prices for the Atom 4RR have not been confirmed yet.
Since its inception in 2000 with a 120hp Rover-supplied engine and a simple tubular chassis, the Ariel Atom has undergone four generations of evolution, with the Atom 4RR now in its fourth generation. The Atom 4RR is primarily designed for track use, and production will be limited to 25 examples.
Expected features for the Atom 4RR include a Quaife-supplied six-speed sequential transmission, adjustable suspension, and switchable ABS brakes. With impressive performance estimates suggesting it can accelerate from 0-60mph in less than 2.7 seconds and reach 100mph in less time than the 6.5 seconds needed by the 4R model, the Atom 4RR is shaping up to be a fierce competitor in the world of high-performance sports cars.
