I have compiled a list of the cars that I believe look the most menacing, glaring, pissed off, angry or downright sexy in this post. Intimidating front fascias and headlights usually reinforce this visual appeal, so I will start off with a car with a sweet front end, the Alfa Romeo Brera:
TVR Sagaris - Gills/fins everywhere!
Porsche GT3 RSR - The ultimate Porsche, ready for the track from the factory
Peugot 908 RC - Incredible concept car with a Twin turbo diesel V12 (700HP)
Mercedes roadster - Streamlining at it's finest
APR GTI-R - 375 HP GTI concept car
Tumbler - Featured in the latest Batman installments
