Autotechnik + Tuning Thunderstorm BMW M3 -- Click above for image gallery

Autotechnik + Tuning has done a job on the BMW M3, but if you don't look closely, you might miss it. Echoing a sentiment we love, they declare "At first glance you cannot estimate the scope of retrofitting." However, while we appreciate their tuning philosophy, we're not so sure about their tuning math.

ATT adds a supercharger and remaps the engine software, all of which bumps the M3's horsey count from 414 to a nice, round 500. To get that bad boy in your engine bay will cost you a tear-shedding €11,749 ($17,455 U.S.). But that's not all: a new exhaust, KW coilovers, and ATT-TEC Le Mans wheels on 20-inch rubber will add more than €7,000 ($10,399 U.S.) to the line at the bottom of the invoice. Those are the kind of numbers that'll give you a concussion, especially when we're talking about an 86-horsepower improvement.

Either way, you can read about it in ATT's own words in the presser after the jump, or check it out in the gallery of photos below, and if nothing else, at least that's free.

PRESS RELEASE:

Thunderstorm M3: Up to 500 hp with the compressor

November 2009 -- M3 is used to characterize 3 series top model of German car producer BMW. ATT tuner called its new power car Thunderstorm M3. Rastatt tuning specialists put much effort and creativity not only in design but also in great driving performance. At first glance you cannot estimate the scope of retrofitting, but the design is definitely not too stylish. Moreover, ATT has paid attention to powerful performance tuning.

The inbuilt compressor together with engine software optimization greatly increase engine performance. It is provided for by unique exhaust system with optimized dynamic pressure (available in two sound variations) for 1'355.00 Euro with 4x90 exhaust pipes increasing engine power up to 500 hp. The price for engine retrofitting is 11'749.00 Euros, including installation.

In order to correspond to driving performance, ATT gives its an upgrade in chassis. Now, KW coilover suspension Variant 3 (2'029.00 Euro) guarantees better road-holding, even at high speeds.

Huge ATT-TEC LeMans 20" alloy rims increase body overall width: 8.5x20 and 10x20 alloy rims with Michelin Pilot Sport 2 245/30 ZR 20 and 285/25 ZR 20 tires cost €3,475.00, mounting & balancing included. The set is completed by 20 mm distance washers (for 393,00 Euros) on the front and rear axle.

Optionally you can order an interior packet for the passenger cabin with either carbon parts or Swarovski crystals.

      Nice car but I think you could make more power at less cost with the N54 motor.

      "RAIN" ... what an appropriate word for the E93.. Leaky roofs are a problem BMW is struggling with on the E93 3'er 'verts
