It's not often that an updated Ariel Atom
comes out, so the occasion is certainly one to relish. Particularly considering that it's one of the most extreme performance machines on the road. And today is one of those days as the small British track-happy carmaker has revealed the first details of its new Atom 3.5. The base naturally-aspirated 2.0-liter Honda
iVTEC engine from the Atom 3 remains untouched at 245 horsepower, but the supercharged version has been fitted with a new ECU, fuel system and intake to boost power from 300 hp to 310.
