AC Schnitzer has announced the introduction of their very first tuning program for the new BMW 4 Series.

The only visual upgrades will be 18 to 20-inch wheels, and a lowered ride height due to adjustable sports suspension. Under the hood the three engines will get upgrades that will deliver more power.

The base 420d will get a 34 HP boost to develop 218 HP, the 428i will increase from 245 HP to 295 HP, and the 435i will get up to 360 HP.

The interior will be enhanced by a "Black Line" aluminum handbrake handle, gear knob with digital shifting display, an aluminum pedal set and foot rest, new floor mats, and an aluminum cover for the i-Drive system controller.

This is great news for people who will be buying the 428i, it will be one of the higher production 4 series models and being able to have power increase from 245 HP to 295 HP will have a lot of people pulling out their wallets.

I'm more interested in how much torque you can get out of the 420d because the 335d could be tuned to a beast.

Yeah any information on torque? the increase in horsepower on all three engines is great but knowing torque will help, especially on that diesel.
how much more of an increase can we expect though
