There are a few aftermarket specialists out there that pump out builds with a steady regularity, much like AC Schnitzer.

After teasing the new kit for the BMW 4 Series Coupe, the tuner finally decided to share with us some details on what they have been cooking up.

While the world debut will be at the 2013 Essen Auto Show, we already know what they are planning. First off, pretty much every engine that will be used in the 4 Series has seen some tinkering for that extra oomph. Thus, we can get the 420i from 184 HP to 245 HP, the 428i from 245 HP to 295 HP, the 435i from 306 HP to 360 HP, the 420d from 184 HP to 218 HP, the 430d from 258 HP to 309 HP and finally, the 435d from 313 HP to 360 HP.

This build also includes some body work, mainly for the front and rear, while also sporting custom wheels from AC Schnitzer. Various trims for the interior can also be expected, and when it’s all done, the now dubbed ACS4 Coupe is another great product from AC Schnitzer.
