The Audi S5 is no slouch at 354 horsepower, but German tuner MTM isn't satisfied and has given the 4.2-liter V8 a serious kick in the pants with an intercooled supercharger package that boosts horsepower to 505 and torque to 403. That's good enough to hit 60 mph in 4.3 seconds and reach a top speed of 186 mph. MTM is also offering a high-flow exhaust system, coilover suspension system, 15-inch brake system, and unique 21-inch wheels. Hmmm... an MTM supercharged S5 or an R8? Decision, decisions.

Motoren Technik Mayer from Wettstetten, Germany, puts the Audi S5 under pressure. As "MTM GT Supercharged" the sporty coupe's supercharged engine demonstrates impressive performance data. Together with bigger brakes, a coilover suspension and other minor changes, the result is an overall package which can take on the race track.


Watch out, when it gets loose! At the slightest pressure on the accelerator the MTM S5 GT Supercharged rockets forward with brute force. The compressor added to the Audi 4.2 liter V8 by MTM is what makes this possible. An MTM intercooler housing with integrated water cooling ensures that the engine can always generate maximum performance. Overall, instead of the stock 354 hp, there is now all of 505 horsepower at 7190 rpm available. This makes an engine output of 120 hp per liter! The torque boost by 106 to 546 Nm emerges in vehement intermediate bursts, to which the driver can get addicted. The sprint from 0-100 km/h takes 4.3 seconds, turning many super sports cars green with envy. And up to its top speed of 300 km/h it can hold its own with any of them.

The evenly powerful, dynamic power display is underscored by a flow-optimized stainless steel sports exhaust system. The goose pimple-raising sound is released by four tailpipes, each 90 mm in diameter.

Curve-hugging and agile

MTM equipped its GT Supercharged with a perfectly tuned coilover suspension and in addition amended the axle geometry with higher camber angles. After the change, its driving dynamism and curve-hugging characteristics are so pronounced you never want to drive straight-ahead again. The steering characteristics are more precise and the agility enhanced, while road handling remains quite neutral.


Since a performance-enhanced vehicle also has to be reined in quickly, MTM improved the brake performance, too. Consequently MTM always provides the appropriate brake system for cars of all performance classes. In the case of MTM GT Supercharged, the Bavarian specialists upgraded the deceleration with a new brake system on the front axle. This is a brake system with 8-piston fixed calipers and 380x34 mm pitted brake discs. The package includes the flexible steel lines and attachments. With the system the driver can decelerate the MTM GT Supercharged from 100-0 km/h within about 35 m. The "pitted" brake discs incidentally represent a special design, manufactured especially for MTM. Typical of "pitted" brake discs are the holes which do not completely penetrate the disc. They look like and share the characteristics of a perforated disc, but hinder the crack formation which normally occurs after lengthy use.

The small difference

Optically the GT Supercharged does not look very different from the series model. Here MTM has gone in for understatement. Nevertheless – apart from the MTM exhaust system's pipes – the "bimoto" MTM rims take care of a look clearly distinguished from the series. The eye-catching wheels are available in "shiny silver", "titanium" and "diamond cut" finishes. MTM provides the "bimoto" rim for the S5 – as for other A5 models too – in 10.5x21" as a complete rim set together with 295/25/ZR21 tires.

At MTM the general rule is: special wishes are met. Customization is also carried out on an individual basis!

      MTM did a good job. The wheels aren't very impressive. Audi should take a look at the M5/M6's standard wheels and make those available on this car.

      Yet the A5/S5, and the rumored A5 Avant, is nothing special of a car. Walter de'Silva is performing a disservice to himself if he seriously argues that this car is the most beautiful he's ever designed. It's far too plain, characterless, and generally lacking of any desirability over its immediate competitors.

      Purchase a 2008 Honda Accord Coupe if you A) wish to save twenty to thirty-thousand dollars and B) if you like the design of the A5/S5. The new Accord coupe strongly approaches the A5/S5's overall profile, and in its best color (black), challenges the Audi for the better stance.
        • 7 Years Ago
        The Accord coupe looks like an A5 in the same way that Steve Buscemi often gets mistaken for Matthew McConaughey.
        • 7 Years Ago
        What you're saying about the Accord makes perfect sense, since they look similar. Go for it if that's all you use to determine which car to buy. By any other measure, of course they don't compare. My personal preference is I can't stand to drive a car that I see 20 of on the way to work.
        • 7 Years Ago
        The Accord isn't really that bad of a car. And against the A5, it's got more power for considerably less money. It gives up a lot in terms of refinement and handling, but you'd expect that with the price difference. It's not the boring-mobile that people here make it out to be.

        Case in point: I'd take an Accord Coupe V6 over the new TSX. (not because of the Acura's looks, but because of its steering)

        So Carletti makes a good point, but I'd pay the extra for the A5. While I agree that the Accord Coupe is great in black (because it slims the car down), it's no A5/S5.
        • 7 Years Ago
        Wow, can you pass some of that stuff you're smoking!

        The A5/S5 are some of the most disctinctive cars on the road today in the sports coupe sector. Neither the 3 series coupe, nor the CLK Mercedes come close to the wide stance and low roofline of the Audi. To compare it to an Accord is just... well dumb.
        • 7 Years Ago
        don't purchase the accord if you've a) ever driven both cars or b) ever driven both cars.
      • 7 Years Ago
      so sick...
      • 7 Years Ago
      Man, I wish BMW gave superchargers as an option.

      Having seen in person both cars, I must say that the S5 is even more exotic and beautiful looking than the R8. However, given your choice, I would choose the R8, if only because I'd know I'd be covered by warranty (or at least be replacing more readily available parts) when Murphy's Law inevitably strikes.
      • 7 Years Ago
      Chipped 335i Coupe for me, please..
      • 7 Years Ago
      What a stunner. Me thinks black is the new black!
      • 7 Years Ago
      to answer the question posed in the article above, I'll go MTM S5 over an R8. it's equally if not more exclusive, just as quick more seating, a trunk, less ostentatious, and very cool in black. just no lower decal please.

      neat car.
        • 7 Years Ago
        How about an MTM R8, no decal, black all around, blacked chome grille, matching wheels, with 5% tint...and just for good measure, a pair of mini-guns located just to the inside of the lheadlamp fixture. I'd take one of those, or just the Tumbler from Batman Begins/Dark Knight..let's take a vote!
      • 7 Years Ago
      An "intercooler" in a supercharged vehicle is actually called an "aftercooler" Just thought I'd let people know that.
        • 7 Years Ago
        I think you mean "inner-cooler"
      • 7 Years Ago
      I've always liked most of MTM's creations, and this one is no different. I've always liked the A5 anyway, but I think this one is hot. The wheels are too big for my tastes... I'd stick with 19 inches or less... but I love the rest of it. Oh, and the 505hp is pretty cool too.
        • 7 Years Ago
        Definitely, and some of the 19s that come from audi are insane, no point in changing them for some aftermatket gaudy abomination (not that these are ugly, they are just not that nice)...
