If a standard Ariel Atom is a bit, well underwhelming for you, then perhaps a 500bhp light weight, high revving V8 will pique your interest? The 2012 Ariel Atom V8 500 earns a bay in my garage (for those rainy days)
2010 Arial Atom. A bare bones hyper car. Looks like a go- cart, goes like a Saturn V rocket... 0-60 in about 2.4 seconds. And it's the closest thing to a Formula 1 race car in regards to handling. Not street legal in the U.S. of course.
