Ariel Atom 4RR: For a brand that thrives on the extreme, Ariel has taken things to an entirely new level with the launch of the Ariel Atom 4RR. Celebrating 25 years of adrenaline-fueled motoring, the Atom 4RR is not just a tribute—it’s a milestone. With 525bhp under the bonnet, this is officially the most powerful Ariel Atom ever built, making it the new king of minimalistic, high-performance engineering. And yes—it’s road legal, which makes it all the more ridiculous in the best way possible.
Developed as a sharper, faster, and more track-focused version of the already wild Atom 4R, the 4RR features a heavily revised version of the 2.0-litre turbocharged Honda Civic Type R engine, fine-tuned for maximum output. Thanks to upgraded internals, an optimized fuel delivery system, and high-performance oil components, Ariel has managed to squeeze out an eye-watering 525bhp and 406lb-ft of torque from this featherweight machine. Combine that with a kerb weight well under 700kg, and you’ve got an insane power-to-weight ratio that rivals hypercars.
From the aggressive aero upgrades—including an F1-style front splitter, carbon fibre enhancements, and a large rear wing—to its ultra-lightweight tubular chassis and motorsport-grade components, the Ariel Atom 4RR isn’t just a weekend toy. It’s a full-blown track weapon for the most dedicated driving enthusiasts. And with only 25 units being made, it’s also one of the most exclusive cars Ariel has ever produced.
