German tuner G-Power is known for building programs that turn sporty vehicles into performance savants on four wheels. It’s worked its magic on a handful of BMWs over the years, but now, it’s turning its attention to Mercedes-AMG, specifically the German automaker’s powerhouse wagon, the E 63 S Wagon. At the core of G-Power’s new tuning program for the E 63 S is an engine upgrade that’s sure to rock the socks of owners who are crazy enough to get the kit. The program is definitely not for everyone, least of all those who are more than happy with having over 600 horsepower to play with. But, for the rare few who think that 600 ponies isn’t good enough, this new kit from G-Power should be right up your wheelhouse.
