Just as we hear reports of Audi planning a race-ready but street-legal R8 GT3, MTM comes out with this – a massively fast, supercharged, lightweight, Rear-Wheel-Drive version of the V8-powered supercar called the R8 GT3-2. The “2″ at the end represents its drive wheels, differentiating it from the standard AWD cars.

While the performance enhancements are significant (and we will go over those in the following paragraphs,) what we really need to focus on here is that this is an Audi R8 without its quattro AWD system; it’s only driven by the rear wheels. While that may seem like a disadvantage to some, others (especially racers,) will consider this a godsend and buy one based solely on that fact. Not only does getting rid of quattro lighten up the car, but gives it an entirely new driving dynamic. RWD cars are more fun to drive, for one, but can also be driven more aggressively and can be taken around turns sideways (powersliding, drifting,) whereas AWD cars have trouble doing that.

So, what else has been changed? MTM supercharged the R8, effectively giving the 4.2-liter V8 engine 560 HP – 35 more than the V10 version with significantly less weight. It’s only boosted to 8 psi, so crank up that boost and you’ll get even more power. Zero to 62 mph comes in only 3.9 seconds, up to a top speed of 197 mph. MTM also tacked on a special exhaust to increase performance and make the modified R8 sound unmistakable. A special adjustable suspension is added to the car, along with 20-inch lightweight forged wheels wrapped in high-performance Dunlop tires.

Outside, MTM kept it mostly stock, save for replacing the front spoiler, side skirt and rear wing with their own lightweight (and more aerodynamic) carbon fiber pieces. Inside, MTM gets you some Recaro carbon racing seats.

If you’re interested in an MTM Audi R8 GT3-2 – and who would blame you – you can order one from MTM directly or give them your existing R8 for a conversion.

MTM TT-RS

A few months ago we got a look at the Sportec TT-RS, a tuned version of Audi’s high performance sports coupe tuned to 400 horsepower by only modifying the car’s ECU.

This time, German tuners MTM get their hands on a TT-RS and make it even better. By taking the 2.5-liter turbocharged five-cylinder engine and tweaking the ECU and adding their own high performance exhaust, MTM was able to squeeze out 424 hp – 84 more horsepower than the stock TT-RS. The power enhancements allow the MTM TT-RS to travel from 0 to 62 mph in only 4.2 seconds and reach a top speed of 181 mph.

The MTM TT-RS package comes in three varieties, the above-mentioned 424 hp version being the most powerful – and most expensive – running you about $12,900. If you don’t have that kind of cash lying around, you have the option of the 404 or 408 hp versions as well, which will cost about $2,800 and $7,000, respectively. Optional 19- or 20-inch BIMOTO wheels are also available.

MTM Supercharged Audi S4

German tuners MTM have given the Audi S4 and S5 Cabrio enough power to compete with their up-trimmed siblings. Through the use of their M-Cantronic ECU system, MTM has given the two cars – both powered by the 3.0 TFSI V6 engine – 430 horsepower, which is only 10 hp less than the stock Audi RS4’s V8 engine.

Along with the M-Cantronic system, MTM uses new exhaust components to help with power delivery. The MTM S4 is also equipped with bigger brakes and 8-piston calipers, a lowered suspension, and 19-inch Bimoto wheels.

430 horsepower get the MTM S4 from zero to 62 mph in 4.6 seconds with the 6-speed manual transmission, and can reach a top speed of 177 mph with the optional V-Cantronic system which removes the top speed limiter from the stock ECU.

The kit is not cheap, either. For both the M-Cantronic and V-Cantronic system producing 430 hp, the system costs $4,600 USD, another $6,183 for the exhaust system, and $6,046 for the wheels. The suspension tuning is $1,048, and the big brakes are $6,654, coming to a total of $24,531 for the MTM S4, plus the price of the car, if you don’t add any other options.

MTM Audi R8

German tuner MTM has taken Audi’s R8 to the next level. Not only have they added the eye-catching (or eye-bleeding) Kermit-the-Frog-green from the Porsche GT3 RS, they’ve increased engine output to an incredible 560 horsepower – higher than the 520hp 5.2-liter V10 promised in the R8 5.2 FSI Quattro coming soon.

They’ve achieved this 120hp boost by adding a supercharger, a reprogrammed ECU, and a quad-exhaust for free-flowing air out of the more powerful engine. Not wanting the R8 V10 customers to feel left out, MTM has developed an ECU program to allow to achieve the same 560 horsepower from their machines.

In addition to the increase in power and wild color scheme, MTM also includes a full aerodynamic body kit made completely from carbon fiber, revised carbon fiber side blades, and 20-inch forged Bimoto alloy wheels. Suspension upgrades include lowering springs with an optional lift-kit for burbs and speed bumps (Lamborghini-style.)

As you can sort of see from the interior picture below, you can opt for matching green stitching and carbon fiber appointments inside the R8, which may or may not look very good.

As cool as the paint job looks, I could do without the resemblance to Porsche, and stick with the excellent performance upgrade. No pricing is announced at this point, but expect to shell out a pretty penny for these pricey upgrades.
