I'm not sure it really was such a big technical achievement.
2006 BMW M6 ($100k)
500 hp V10, 7-speed SMG, front engine, RWD
3900 lb, 191.8" length, 109.5" wheelbase
2012 Lexus LFA ($376k)
552 hp V10, 6-speed SMG, front engine, RWD
3570 lb, 177.0" length, 102.6" wheelbase
Seems like a lot of money and effort to build what's essentially an M6+.
