Isringhausen Imports has received what is said to be BMW’s fastest production car to date: a 2017 M4 GTS. This track-ready but street-legal car recently completed a trip around Germany’s famous Nürburgring in 7 minutes and 28 seconds – that’s nearly 30 seconds faster than a standard M4.

The car’s twin turbocharged six-cylinder engine receives an added boost of power from an innovative water injection system, taken from the BMW M4 MotoGP Safety Car. According to carscoops.com:

“What this system does is inject a fine spray of water into the intake manifold plenum chamber (where it evaporates), significantly lowering the temperature of the intake air, which in turn, reduces the final compression temperature in the combustion chamber thus allowing for an even higher boost pressure for increased power.”

The injection system raises engine output to 493 hp, a 75-hp increase over the base model, allowing for a 0-60 mph sprint in a blistering 3.6 seconds. Top speed is 189.5 mph.

BMW’s M division also equipped the M4 GTS with a three-way adjustable M coilover suspension, an adjustable carbon fiber front splitter and rear spoiler, M Sports seats with cut-outs, and an Acid Orange roll bar mounted behind the front seats.

This special edition M4 is limited to around 700 units worldwide, with around 300 units for the US market.
