The BMW 3-Series (known in-house as the F30) has finally made its official debut today. Revealed online, the 3-Series sedan features some new styling tweaks and looks as good as ever. Some notable differences in the styling include a new, longer front-end. It is taller and wider than previous generations while the trademark split grille makes its way up to the headlights. The interior also makes its presence felt, with more legroom and space to chill out in luxury.

This is in addition to four unique trim levels that should help segregate this sedan from many challengers, such as Sport Line, Modern Line, M Sport and Luxury Line. Under the hood, the 3-Series features a range of engines including the debut of BMW's new turbocharged 2.0-liter 4-cylinder engine. The motor puts out a steady 240hp and 260lb-ft of torque, both of which are a nice upgrade to the previous 328i's 3.0-liter inline 6-cylinder powerplant. Performance for the new sedan is said to measure 0-60mph in 5.7 seconds and hit a limited top speed of 130mph.

The 335i model will maintain its standard turbocharged 3.0-liter inline 6-cylinder engine that produces the same 300hp and 300lb-ft of torque. The engine has gained some serious fuel-efficiency bonuses, however, with new features like Brake Energy Regeneration, ECO PRO mode and the now commonplace Auto Start-Stop. An eight-speed transmission will help transmit power to the wheels, which in turn should help the sedan reach an estimated 32.6mpg. The 2012 BMW 328i and 335i will come to the U.S. market in February 2012.

A hybrid variant of the 3-Series is also expected to arrive relatively soon after the first models make their way to showrooms. Scheduled for late 2012, the hybrid variant will pack the ActiveHybrid3 powerplant that can put out a combined 335hp and 330lb-ft of torque. No pricing information has been released yet for any of the trim levels, though the German automaker is expected to release them as the 3-Series gets closer to distribution.
