Big Turbo BMW M4 is So Fast It’s “Ridiculous”

European Auto Source Tunes BMW M4 to 600 Rear-Wheel Horsepower

The BMW M4 is already a powerful car. In standard tune, its twin-turbo, 3.0-liter I6 pumps out 425 horsepower. The Competition Package raises that output figure to a round 444 (and drops the 0-60 mph time to 3.8 seconds).

Depending on which vehicles you’re used to driving, you could say the M4 is a fast machine. However, like any car, it can be faster. That’s where companies like European Auto Source (EAS) come in. In fact, a representative of the California-based firm makes an appearance in the following The Smoking Tire video.

EAS turned its wrenches on the M4 and gave it a suite of cosmetic add-ons, including a new front lip, canards, and rear diffuser and wing. They swapped out the shocks for upgraded adjustable Moton coilovers and installed an aftermarket big brake kit.

EAS kept those wrenches turning under the M4, too. They gave the M4 a full Akrapovič exhaust system (sans the headers). Most importantly, EAS’s techs threw a pair of larger turbos under the hood. Thanks to those, the M4 now makes 600 horsepower and 600 lb-ft of torque – at the rear Pirellis.

Just looking at those figures on paper, you could call EAS’s shop car impressive. Matt Farah uses other words, such as “mental” and “ridiculous”, to describe how quick EAS made the M4. In fact, he jokes that EAS should make people sign a waiver before they experience that kind of speed for themselves.

That’s not the worst idea in the world. Even though you’re able to hear the turbos under the hood and a GTS-like burble from the exhaust, Farah says the EAS-tweaked M4 masks speed. It’s even able to break its rear tires loose going into third gear, something Farah hasn’t experienced a dual-clutch car do before.

Showing Farah something new? That takes power. The EAS BMW M4 has it.
