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.

Derek Shiekhi's father raised him on cars. As a boy, Derek accompanied his dad as he bought classics such as post-WWII GM trucks and early Ford Mustang convertibles.

After loving cars for years and getting a bachelor's degree in Business Management from Texas State University, Derek decided to get an associate degree in journalism from Austin Community College as well. His networking put him in contact with the editor of the Austin-American Statesman newspaper, who hired him to write freelance about automotive culture and events in Austin, Texas in 2013. One particular story led to him getting a certificate for learning the foundations of road racing.

While watching TV with his parents one fateful evening, he saw a commercial that changed his life. In it, Jeep touted the Wrangler as the Texas Auto Writers Association's "SUV of Texas." Derek knew he had to join the organization if he was going to advance as an automotive writer. He joined the Texas Auto Writers Association (TAWA) in 2014 and was fortunate to meet several nice people who connected him to the representatives of several automakers and the people who could give him access to press vehicles (the first one he ever got the keys to was a Lexus LX 570). He's now a regular at TAWA's two main events: the Texas Auto Roundup in the spring and the Texas Truck Rodeo in the fall.

Over the past several years, Derek has learned how to drive off-road in various four-wheel-drive SUVs (he even camped out for two nights in a Land Rover), and driven around various tracks in hot hatches, muscle cars, and exotics. Several of his pieces, including his article about the 2015 Ford F-150 being crowned TAWA's 2014 "Truck of Texas" and his review of the Alfa Romeo 4C Spider, have won awards in TAWA's annual Excellence in Craft Competition. Last year, his profile of Wagonmaster, a business that restores Jeep Wagoneers, won prizes in TAWA’s signature writing contest and its pickup- and SUV-focused Texas Truck Invitational.

In addition to writing for a variety of Internet Brands sites, including and, Derek also contributes to other outlets. He started There Will Be Cars on Instagram and Facebook to get even more automotive content out to fellow enthusiasts.
