Nothing is more pure in the world of motorsports than a race car in action. It’s better than any static image could ever be but more importantly, it gives us a glimpse of the beast at work, man and machine doing their thing, speaking volumes about their purpose for being there. Racing!

Super Bild, for those just joining us, means great picture in German or more loosely translated “Super pic”. Today’s image of the 2013 BMW Z4 GTE is just that, a Super Picture. No, this picture isn’t of the BMW Motorsport campaigned Team RLL Z4 GTE racing because it hasn’t made its racing debut here in the US. It will do so on March 13 through the 16th at the famed Sebring International Raceway in Florida.

But the BMW Motorsports Z4 GTE racing success around the world is well documented so far. BMW Z4 in 24 hours of Dubai

The official driving pairs for the coming season are as follows: Car number 55 will be driven by Bill Auberlen (US) and ALMS rookie Maxime Martin (BE). Dirk Müller (DE) will contest all the races in the number 56 car. Joey Hand (US) and John Edwards (US) will alternate as the two-time ALMS GT champion’s driving partner. Edwards will stand in for Hand when he is unavailable due to his parallel commitment in the DTM. Jörg Müller (DE, #55) and Uwe Alzen (DE, #56) will bolster the squad at the endurance races at Sebring (US) and Road Atlanta (US)
