Nurburgring continues to be the popular choice for testing new vehicles. Spied this week banging out a few laps in Germany, the 2013 BMW 3-Series looks pretty good decked out in just a bit of camouflage. It still contains some of the current E-90 3-Series look, however, the four door sedan can be seen sporting an aggressive dual-exhaust and square shaped 'angel eye' front lights. The new 3-Series will most likely be rear-wheel-drive and have a forced-induction inline six-cylinder.

Standard models 3-Series could have a forced-induction four-cylinder instead. It is also expected to use BMW's EfficientDynamics technology. Low drag aerodynamics and high-tech electronics should make the next 3-Series a class above the current car. One of the coolest features on the new 3-Series is the 'air curtain.' The car uses a special series of ducts and vents that allows air to slip over the wheels, greatly reducing drag. To even further increase efficiency (and keep a BMW driving experience), plans to deliver hybrid technology to the line will come eventually.

The X6 ActiveHybrid and ActiveHybrid 7 will make its debut on the 3-Series and will be marketed mainly to U.S. buyers. Photos courtesy of F30Post.com
