I’ve said it before, and I’ll say it again: the Ariel Atom looks like some freakishly fast UTV. And with the new Atom 4RR, I’m not backing down. Sure, it’s technically a road-legal, track-focused supercar-killer, but come on, no roof, no doors, exposed tubular frame? That’s UTV behavior. It just forgot to bring the mud tires and the camo wrap.
Built to celebrate 25 years of jaw-dropping lunacy, the 4RR is Ariel’s most hardcore Atom ever. It takes the already-insane 4R and dials it up to Final Boss mode. Power comes from a specially developed version of Honda’s K20C1 turbocharged 2.0-liter four-cylinder, lifted from the Civic Type R. But Ariel didn’t just plop it in and call it a day. They added new fuel and oil systems, better cooling, and some serious engine magic to push 525 horsepower and 406 pound-feet of torque. That’s over 100 ponies more than the 4R, and over way more than any UTV has any right to dream of.
This featherweight rocket ship tips the scales at just under 650kg. That’s about the same weight as a big-bore side-by-side—except this thing can likely hit 60 miles per hour in around 2.5 seconds. Put another way: it’ll out-accelerate most supercars and literally everything at your local trailhead, including your buddy’s turbo RZR on paddle tires.
