Feature Flick: How To Build A BMW Z4 GT3 Racer

#BMW, #Z4

Today's video find centers on the hand assembly of a BMW Z4 GT3-spec racecar. Starting in basic shell form, mechanics are shown assembling the car from the ground up in a neat time-lapse YouTube clip.

Although based on a BMW Z4, the GT3-spec racecar has few components found in a stock model. Starting with a body-in-white and several boxes of parts, Team West Coast Racing recorded every stem in the hand assembly of the car. The team notes it took some 600 hours of labor to finish, but thanks to the help of time-lapse video, we can observe the process in just 3 minutes and 40 seconds.

Throughout the clip, mechanics meticulously fit and refit parts to ensure the proper fitment. Much of the video involves running the spider web of wiring required in a modern racer, while carbon fiber body panels are seen coming and going throughout. One of the more fascinating aspects are the tight clearances found under its hood, due to cramming a V-8 powerplant and enormous air ducts into the relatively small engine compartment.

BMW recently revealed a revised version of the Z4 GT3, which includes a long list of upgrades for the new year. For 2011, the GT3 's V-8 receives a 10-percent increase in displacement, bringing it to a 4.4-liter unit. Although output is undisclosed at this time, we're confident it's improved over the 2010 model's 480-horsepower figure, could easily crest the 500-horsepower mark. New multi-spoke deep dish wheels measure 18 inches in diameter, but front and rear rims now have a staggered width of 12 and 13 inches, respectively.

The Z4 GT3's success story began earlier this year, when Team Schubert clinched the top podium spot at the Dubai 24 Hours race in January. Last year, the Z4 secured a pair of wins in the FIA GT3 European Championship series.

Those interested in the latest GT3-spec Z4 will have to shell out a hefty sum for one. Pricing starts at $457,000, roughly $57,000 more than the 2010 model.
