BMW produces this video showing off both the Z4 and its GT3 racer version.
BMW has just released this video showing a Z4 facing off against another Z4. However, the latter of the two is the GT3 racer version. The Z4 GT3 was launched back in early 2010 and won the Dubai 24 Hours this past January. The standard production Z4 is powered by a 3.0-liter inline-six, the GT3 car has a 4.4-liter eight-cylinder under its hood. And while the road car has a reasonable base price of $54,000, the racer starts off at €315,000, or roughly $453,000 according to current exchange rates.
The video is pretty cool as it goes back and forth between the road going version and the GT3 car. BMW didn't even use any old elevator music. Although it's a bit techno, we can still clearly hear the sound of the engines.
