BMW

BMW initially revealed the i8 back in 2009 with the original Vision EfficientDynamics Concept, a design whose lines have stayed consistent over time and are plainly seen in this upgraded version.

German tuner Manhart isn't particularly renowned for its modest automotive modifications instead, it favours use of carbon fibre as its hallmark style.

The sparkling new BMW M3 Touring features a suite of upgrades from German tuner AC Schnitzer, which transforms the already extremely quick estate into something that would feel right at home on a racetrack.

With a small batch of 250 high-performance GTs, Alpina adds its own touch to BMW's M5.

It's a remarkably uncommon BMW M1 "AHG Studie," and you may not be familiar with these.

The 3.0-liter twin-turbo straight-six in the CSL has been upgraded from the conventional 542 horsepower to a far more adequate 692 horsepower.

Unfortunately, you won't be seeing the modified BMW i4 by AC Schnitzer stealthily tracking down criminals anytime soon.

The factory-modified M2 will debut at the Essen Motor Show.

Aerodynamic Development Race Optimization (ADRO) claims to be the first business to commercialise an alternative front bumper for the bmw m4.

This BMW was modified by a German tuning company, and it isn't any more ugly than when it was first built.

BMW describes its carbon components for the powerful M3, but those tailpipes are too much for us to handle.

It was created by Polish tuner Carlex Design, and the finished product barely qualifies as subtle.

This M3 Touring is the new MotoGP safety vehicle, as you may have guessed from the stickers, lights, and unique "50 years of M" livery.

The BMW M4 Competition, with its 3.0-litre twin-turbo straight-six engine producing 503bhp and 479lb ft of torque, is fairly powerful by most people's standards.

Last week, the world saw the concept version of BMW's entry for the 2012 Deutsche Tourenwagen Meisterschaft (DTM) series, which is based partly on the existing E92 M3.

Just when you thought 'BMW' and 'looks terrible' were no longer trending on Twitter, along comes Zacoe with a modification of the M8 Gran Coupe that will, shall we say, 'question' conventional knowledge.

Are you dissatisfied with your new BMW M5 CS, which is the most powerful M vehicle ever produced?
Think 626 horsepower, 553 pound-feet of torque, and a 0-62mph time of 2.9 seconds is a tad slow?
You'll need to visit German tuner G-Power...

If someone ever tells you that the 616bhp BMW M8 Competition convertible isn't powerful enough, point them to the MH8 700 Cabrio from German tuner Manhart.
