This Speedy New BMW is a Street Legal Track Weapon

When BMW designed the new M4 GTS, they clearly had one thing in mind: speed. So what’ve they added?

For starters, how about the twin-turbo 3.0-liter inline-six, which has a 16% output increase over the standard M4. That boost pushes the sports car to 493 horsepower, hitting 60mph from standstill in 3.7 seconds, and a top speed of 189.5mph. Impressed yet?

If that’s not cool enough, this BMW is the first production road car to be fitted with a water injection system. This is how it works: taking into account that water absorbs heat from the surrounding air when it changes phases, water is injected as a fine spray into the intake manifold chamber where it evaporates, thus lowering the intake air temperature. This creates a reduced final compression temperature in the combustion chamber, allowing the turbo engine to go to work with higher boost pressure.

Long story short, that’s where all the car’s extra juice comes from.

Aside from being a street legal track weapon, BMW keeps the aesthetics sharp, adding an aggressive aerodynamic body kit featuring an adjustable front splitter and a new hood. And of course, that massive new carbon-fiber rear wing just screams ‘speed’.

Oh and the rear seat? Gone. A glass-fiber-reinforced plastic shelf and rear panel, both covered in Alcantara, take its place.
