Forum 4Tuning - Bmw M3 GTR

Bmw M3 GTR.......un vis frumosssss, hai sa postam in sectiunea asta poze, filme cu bmw m3 gtr! Asta e tot ce am eu despre m3 gtr:

BMW will race with two sturdy, 500-horsepower-strong coupes in the 24 Hour Races at the Nürburgring and at Spa-Francorchamps. BMW Motorsport Director, Mario Theissen, has a high opinion of the car, “The BMW M3 GTR enables
us to compete for the title.”

The impressive race car, which was designed by Albert Biermann and his team, proved to be a winner more than
once in 2001. In that year, the BMW M3 GTR had its debut for Team Schnitzer Motorsport at the American Le Mans
Series (ALMS) and set new standards in the GT series.

The car won ten races and took ten pole positions with its powerful V8 engine. Already in their very first race, the
driver duo JJ Lehto/Jörg Müller came in third in their BMW M3 GTR, which had been built in less than six months in
Sebring, Florida. After this successful debut, a second BMW M3 GTR was released for Fredrik Ekblom and Dirk Müller.
At the end of the season, the BMW M3 GTRs were so advanced that both cars celebrated four one-two victories in
the last four races.

Consequently, the dominating car of the season secured the title: Jörg Müller won the Drivers’ Championship,
Schnitzer Motorsport won the Constructors’ Championship and BMW finished on position one in the Brand
Championship in the most important foreign market for the company, the United States.

If you take a closer look at the construction of the car, it is easy to see why the BMW M3 GTR has been so
successful. The V8 engine, which is 500 bhp strong, does 7,800 revolutions per minute. With its short strokes, high-
performance and compactness the engine is typical for the M series. The individually designed chassis with
components that are highly aerodynamic and the lightweight construction with body parts made of carbon fibre are
the reasons why the BMW M3 GTR is a racing machine with no match.

In the centre of the BMW M3 GTR is a powerful V8 engine with over 400 bhp. The engine is a short stroke, high
reving power unit following in the tradition of the M engines. The engine is compact which makes it suitable for the
GTR and is possible to install the engine in the M3 due to its back angle of 90 degrees and a flat oil pan.

Lengthwise, the 4-litre V8 is more compact than an in-line 6-cylinder engine, making a new cooling concept
possible. The powerful cooling devices are located directly behind the front apron with one unit cooling the radiator
and the other cooling the oil. The outlets for air, collected by the cooling device are visible on the bonnet.

Due to the late decision for the go ahead with the BMW M3 GTR project, the engine construction only began in mid-
February of the year 2001. The first V8 racing engine was run on the test bench on February 20 and was followed
by a functional test on the BMW circuit in Ismaning near Munich on March 3. The engines are highly efficient like all
M engines which make them suitable for long distance racing.

The GTR drives with the power of a V8 instead of a 6-cylinder engine. Since racing regulations do not permit
sequential gearshift, the GTR has a conventional 6-speed transmission. The racing and road versions of the GTR
differ in safety-related mods, including the cleared interior with welded safety cell, the fast filling system and racing
chassis and brakes.

BMW M3 GTR – a success model celebrates its comeback. BMW will race with two sturdy, 470-horsepower-strong
coupes in the 24 hour race at the Nurburgring.
