What production car is the fastest 0-60mph?

Ariel Atom V8.. 2.3 Seconds $225,000 only 25 made and 500hp 3.0 v8 I think the engine is a highly modified Suzuki hyabusa engine, basically just the heads. so its super light(less than 200lbs) and its one of the highest redline of production engines at 10,600
