Mercedes has released the first details about the 2012 B-Class, ahead of its debut at the Frankfurt Motor Show.

Dubbed a "quantum leap in the compact class," the redesigned model measures 4359mm long, 1786mm wide and 1557mm tall. It has an impressive 0.26 drag coefficient thanks to "numerous optimization measures" that are a result of 1,100 hours of wind tunnel testing. Additionally, there will be an ECO Technology package - with a reduce ride height, underbody cladding and improved window seals - that lowers the drag coefficient to 0.24. If that hasn't sparked your interest, there will also be a sports package which has modified dampers, a 'Direct-Steer' system and a 20mm reduced ride height.

In the tech department, the 2012 B-Class offers Adaptive Headlamp Assist, Blind Spot Assist / Lane Keeping Assist, Attention Assist, Speed Limit Assist, Active Parking Assist, Linguatronic, DISTRONIC PLUS, PRE-SAFE and COLLISION PREVENTION ASSIST with adaptive Brake Assist.

Under the hood, a variety of turbocharged four-cylinder engines will be available. The 1.6-liter petrol produces 90 kW (122 PS / 121 hp) and 200 Nm (147 lb-ft) of torque as well as 115 kW (156 PS / 154 hp) and 250 Nm (184 lb-ft) of torque. On the diesel side, there's a 1.8-liter that develops 80 kW (109 PS / 107 hp) and 250 Nm (184 lb-ft) of torque as well as 100 kW (136 PS / 134 hp) and 300 Nm (221 lb-ft) of torque. Eventually, a 2.0-liter petrol will join the lineup but specifications haven't been released.

All the aforementioned engines will feature a start/stop system and can be paired to a six-speed manual or a new 7G-DCT dual-clutch transmission. Mercedes also hinted the B-Class has been designed to accommodate alternative powertrains so expect hybrid, EV and fuel-cell variants.
