TopSpeed.com brings to you an in depth review of a 2011 BMW M3 supercharged by VF Engineering. Read the rest of the article to find out what exactly VF did to create this beast of a machine.

The M3 is no doubt one of the most impressive BMWmodels ever. It’s V8 engine with 420 HP kept the front lines for quite some times. But even the best car sometimes need some updates. VF Engineering if offering a pretty impressive tuning package for the M3 model that updates both the car’s look but also the engine’s output.

The car started its life as a Vorsteiner carbon fiber GTRS3 widebody kit. Next to this kit, the tuner adds a new set of 20" wheels, huge Brembo brakes and a custom intake manifold craved from a solid block of aluminum.

But this changes aren’t by far as impressive as the one made under the hood. For the V8 engine VF Engineering added a Vortech supercharger that comes with a 6psi, a custom aluminum air intake and an ECU remap. The result is a total increase of 200 HP to an amazing 620 HP.

The styling and aerodynamic package of the M3 GT3RS isn’t exactly a new item in the VF Engineering inventory; we’ve seen it before from the company’s carbon fiber widebody kit.

Having said that, it’s still awesome enough to beat a second mention. The GTRS3 Aero Package gives the M3 a significant body upgrade, one that includes a completely new carbon fiber front bumper with a modular replacement splitter. On top of that, the package also includes extended front fenders, extended side skirts, rear quarter panel fender arch extensions, a wide-stance rear bumper with integrated carbon diffuser, a vented carbon hood, a stainless steel quad exhaust system, a TRS lightweight boot lid that’s available upon request, Brembo brakes, and a set of twin 20" 7-spoke forged wheels.

That’s not even mentioning the car’s army-like dress up, complete with a Military Green paint scheme, which is nicely complimented by military-themed decals plastered all over the car.

The M3 GTR3RS also comes with a stone cold performance upgrade that should make fans of the car stand up and take notice. Already boasting of a 4.0-liter V8 engine that produces an impressive 420 horsepower, VF Engineering took it upon themselves to add a Vortech supercharger, a custom aluminum air intake, and an ECU remap to bump up the car’s output by a staggering 200 horsepower. The final number of ponies sitting under the vented carbon hood? A whopping 620 horsepower.

No word yet on the pricing of the car, but a standard M3 Coupe retails for $58,400 these days. Use that as a peg and estimate how much VF Engineering is charging for the comprehensive tuning program and you’re looking at somewhere in the neighborhood of around $80,000. Maybe even more

To offer a nice comp for this ridiculously awesome BMW M3 GT3RS, we ought to take a look at another project VF Engineering has made in the past, one that involves the mightyAudi R8.

On its own, there’s no denying that an R8 is a lot more exotic than an M3 GT3RS based on merit alone. But this M3 GT3RS is one special cat. For starters, the whole styling and aerodynamic set-up is absolutely fantastic; it’s something that we’d love to have in our garage in a moment’s notice. Contrast that to the minimal work done on the R8 and you have a pretty clear winner in that regard.

As far as the performance upgrades go, the R8 comes with plenty of punch, thanks to a supercharged V8 engine that bumps up the Audisupercar’s output to 550 horsepower. On the other hand, the M3 GT3RS comes with a more extensive tune-up, as evidenced by the staggering bump in output from 420 horsepower all the way up to 620 horsepower.

We love the work done by VF Engineering on the Audi R8, but let’s face it; it can’t hold a carburetor to what the M3 GT3RS is offering. It’s not even close.
