Luckily i wasn't the one who originally stated it... Jeremy Clarkson did. Sure there are more powerful engines out there, race and street alike, however not many small (very small) naturally aspirated engines can produce 420 HP with full California emissions, have a 8000 rpm redline, a throttle response normally saved for F1 cars, manage 20 miles a gallon on the highway. Oh yeah and the engine is about 3 times lighter than anything that slightly resembles it thanks to an array of carbon bits.
