The 13 images that will go into the 2011 Miss Tuning Calendar have been released. They are showing this year's winner Kristin Zipper in some hot poses next to various sports and tuned cars. The calendar features the photography of Max Steam and the shoot took place in the US this summer.

The 27 year old Kristin Zipper is from Mering in the German state of Bavaria and was crowned champion of the competition held in May at Tuning World Bodensee, becoming the official ambassador of the tuning world for a full year.

Aside from the calendar photo shoot, Kristin has also received the keys to her own Nissan sports car.

The German model has gray-green eyes and a 75B cup.
