The mad scientists at G-Power have reworked the company's sinister M5 Hurricane into something even more impressive.
Meet the M5 Hurricane RR – an 800 horsepower beast that G-Power claims is the fastest sedan in the world. The company started by plopping a new set of superchargers onto the M5 sedan's already potent BMW V10.
With a theoretical capacity of 900 horsepower, each belt-driven supercharger delivers air to a single bank of the engine. According to the tuner, this configuration allows for 25 percent more air to enter the combustion chamber. The engine's internals have been completely reworked and balanced to handle all of that extra boost as well.
All of that mojo is good for a top speed of 231 mph on track, which the company says makes their matte monster the fastest four-door extant. If lofty top-speed numbers aren't your bag of tricks, maybe acceleration figures are. G-Power says that 0-60 mph takes around 4.35 seconds and 0-120 mph clicks by in 9.5 seconds.
Yep, that's pretty darn quick for a two-ton sedan. Even better, G-Power will be more than happy to convert any old BMW M5 into the beast you see above, all for the low, low price of $71,780 – plus donor M5. Hit the jump for the full press release.
