2011 BMW Z4 GT3 – Click above for high-res image gallery

The 2011 BMW Z4 GT3 proved it can win races back in January when it took the overall victory at the Dubai 24 Hours. Never one to rest on its laurels, BMW took the car from the winners circle in Dubai and put it right back on a test track. After a good beating throughout March, BMW made aerodynamic and electronic tweaks to get the racer into absolute state-of-the-art shape for customer entries in 2011 GT3 competition.

The BMW Z4 GT3 resembles its production cousin in name and basic shape only. Most of its body panels have been significantly altered to keep the car slipping through the air and bolted to the road.

Under the hood, the production Z's six-cylinder heart has been ripped out and replaced with the same 4.4-liter V8 that sees duty in the M3. The V8 feeds power to the ground through a six-speed paddle-shifted sequential manual. Stuffing all that engineering know-how into the Z4 GT3 isn't cheap, either; the car retails at just north of $450,000. Full press release after the jump.

Modified BMW Z4 GT3 Completes Successful Test Programme

Munich, 8th April 2011. The modified BMW Z4 GT3 has survived its baptism of fire: the GT customer sports car proved itself in a series of intensive tests in recent weeks. The goal of the latest modifications was primarily to improve aerodynamic efficiency in order to ensure the car's competitiveness in the many, hard-fought GT3 classes.

The BMW Z4 GT3, which was launched in March 2010, achieved its greatest success to date in January 2011. Claudia Hürtgen (DE), BMW works driver Augusto Farfus (BR), Tommy Milner (US) and Edward Sandström (SE) won the Dubai 24 Hours for Team Schubert. This was the first outright victory for the BMW Z4 GT3 at a marathon race of this scale, having already proven its potential with wins in its debut season in the FIA GT3 European Championship.

With its elongated bonnet, the driver's compartment towards the rear of the car, long wheel base and narrow wheel arches, the series version of the BMW Z4 boasts an unmistakable appearance. The two-seater provided BMW Motorsport engineers with a good basis for developing a competitive GT3 racing car.

A difference between the production and racing car can be found under the bonnet: while the production version of the BMW Z4 is driven by a six-cylinder engine, the GT3 car is powered by a 4.4-litre eight-cylinder engine.

BMW Motorsport engineers have also fine-tuned the aerodynamics of the BMW Z4 GT3 for the new season, improving the car's performance in this area. When it comes to electronics, the private teams can look forward to innovative BMW solutions: The modern ECU408 takes over the engine management, while the Power400 electronic control unit is responsible for controlling all the actuators. The power is transmitted through a six-speed, sequential gearbox. Gearshifts are now initiated using two paddles.

The steel body of the car comes from BMW Plant Regensburg. A safety cell made of extremely rigid, precision steel tubing is then welded into the body. The engine block of the V8 engine is produced in the BMW foundry in Landshut. BMW Plant Dingolfing contributes the rear axle differential, among other things. Front and rear wings, bonnet, roof, fenders and many other components are made of carbon fibre reinforced plastics (CFRP).

The car is available now at a price of 315,000 Euros (plus VAT) from BMW Motorsport Distribution, email address Z4GT3@bmw-motorsport.com.

      Wow...not even much of a fan of recent Bimmers, but that car is HOT.
      • 3 Years Ago
      When did the M3 get a 4.4? I thought it was a 4.0?
        • 3 Years Ago
        You're right, the regular M3 has a 4.0. I think the M3 GTS uses the 4.4.
        • 3 Years Ago
        The M3 GT2 has the 4.4L.
      • 3 Years Ago
      Man, that is one badass looking MOchine!
      • 3 Years Ago
      $450,000! And worth every penny.
      • 3 Years Ago
      damn that is a good looking car

      ... Time to find between $450,000 to $500,000 in my couch cushions...

      (Finds $5!..)

        Now you just need to find 100,000 couches to look in and you'll be there :D

      so beautiful....

      Does anyone know if it uses a reinforced Z4 chassis or is it just a tube frame with body panels attached?
        • 3 Years Ago
        GT cars are always production based with the exception of Super GT.
        So yes, reinforced Z4 chassis in this case
      • 3 Years Ago
      That looks truly sinister. Nice.
      • 3 Years Ago
      I wish they would create a hardcore version of the Z4 with a v8 in it. I loved my Z4M but I really wished it had a V8 and made that V8 sound. I was always disappointed with how it sounded lol
        • 3 Years Ago
        I'm actually surprised they didn't (or at least haven't yet). BMW engineers admitted the S65 engine would fit in the Z4's engine bay, so I always figured a Z4 M with that engine was a foregone conclusion. Maybe it'd perform too closely to the M3 and they're waiting for the next-gen M3 to come out to do that. Then again, given that the next M3 is going turbo partially for emissions reasons, the longer they wait the less likely it gets.
        • 3 Years Ago
        why not fit the F10 twin-turbo V8 engine??? yes, please! 0_0
        • 3 Years Ago
        My thoughts exactly, but the hardtop in the Z4 is pretty heavy, so a removable top or a canvas one should work. The Z4 houses a inline-6, which is pretty long, so a V12 would fit in no problem. I believe a tuner once put in M's own V10 in there.

        At any rate, the 6-cylinder still sounds fine.
        • 3 Years Ago
        Since, historically, the Z4M and Z3M shared the same engines as the M3, I'm really hoping the V8 from the M3 comes to the Z4.

        Pleeeease BMW!

        And as a Z4M driver, I have to disagree. Great engine sound.

      Dear BMW,

      If you read this, please send one or two of those down under for next Year's Bathurst 12 hour enduro. The two leading Audi R8 LMSs could use some competition...
