If you still haven't seen it yet, here's an HD version of the STI Impreza WRX's lap in the hands of four times WRC champion Tommy Mäkinen. The more conventional four door version tuned by STi managed to lap the Nürburgring Nordschleife in 7min 55 seconds. Impressive for a 305 Hp machine. But again, power isn't anything in the Green Hell, the better balanced sedan body as well as some slight enhancements made for the occasion (and also a four times world champion) sure helped to achieve this good performance.
You can watch Tommy Mäkinen handle the six speed manual gear box and hear the 2.5 L boxer screaming right below. (If you want more Nordschleife action go here)
