AC Schnitzer has expanded its upgrade kit for the BMW 4-Series Coupe just in time for this year's Essen Motor Show which kicks off on Saturday.

Announced at the end of September, AC Schnitzer's customization program for the 4-Series has been revealed in full and it contains a little bit of everything. It begins with a power hike for the 420i from 184 HP (135 kW) to 245 HP (180 kW) while for the 430d output has jumped to 309 HP (227 kW). The tuner massaged the straight-six diesel inside the 435d and squeezed 360 HP (265 kW), up from the standard 313 HP.

AC Schnitzer is already offering power hikes for the 428i from 245 HP (180 kW) to 290 HP (213 kW) and for the 435i from 306 HP (225 kW) to 355 HP (261 kW). They also have a package for the 420d which lifts power from 184 HP (135 kW) to 218 HP (160 kW).

Aside from power upgrades, the German tuner has developed a -25mm suspension lowering kit and various exterior goodies such as a chromed front grille, front and rear spoilers, rear skit protection foil and a different diffuser. On the inside there's an illuminated leather-wrapped gear knob featuring a digital gear display, an aluminum handbrake handle and velour floor mats.
