atom

When it comes to power and lightweight, enough is never enough. And so, Ariel (finally) gives us the Atom 500 V8, an 1,102-pound roadster boasting the highest power-to-weight ratio (1,000 hp-per-ton) of any production car to date. How does Ariel do it? It starts with the engine and gets more insane from there.

Ariel, our favorite purveyors of minimalist motoring this side of a Se7en, are reportedly working on an all-new vehicle that won't be powered by a standard engine and would "break new ground in the same way that the Atom first did."

We've lost track of how many times we've watched Clarkson's track test of the Ariel Atom. It solidified the Atom's place in the track-day hierarchy, impressing with its insane speed, lateral grip and face warping abilities. But for those of us not content to look like a blowfish in full attack mode, Ariel has begun offering an optional windscreen on the Atom, eliminating the need for a helmet.

The new polycarbonate windscreen is semi-frameless, can be detached via five fittings and even includes wipers and a washer system to clear off the bugs that would have otherwise wound up on you and your passenger's forehead.
