As the world is admiring the new Mercedes SLS GT3, BMW’s GT3 racer the Z4 is preparing for this year’s Nurburgring 24 hours endurance race. Matter of fact you can watch it lapping the track for the first time in the video above! The car’s powered by the M3′s V8 engine tweaked to deliver 480 hp. This might not be as powerful as the SLS GT3, but it’s lighter and more agile. Also at JUST 300,000 Euros, it’s a bargain comparing to the Merc!
