Most of the buzz around BMW‘s booth at the Frankfurt Messe is concentrated on the production iterations of the all-electric i3 hatchback and the plug-in hybrid i8 sports coupe, but there’s plenty more to see as the Bavarian firm brought along a number of new cars for their world premiere, including the 4-Series Coupe.

This post isn’t about the 4-Series per se, as we’ve extensively covered the regular lineup before, but about the introduction of a range of bespoke BMW M Performance Parts for the coupe model that will become available from early next year.

Beginning with the performance upgrades for the European market models, an engine kit will lift the output of the 420d’s four-cylinder diesel by 16hp and 20Nm (15 lb-ft), the 430d’s inline-six diesel by 27hp and 40Nm (30 lb-ft) and the 435i’s inline-six petrol by 34hp and 50Nm (37 lb-ft). The gasoline-powered 420i, 428i and 435i can be fitted with a sports exhaust system that includes tailpipe embellishers in chrome or carbon and which can also be ordered as an individual option.

The list of available performance upgrades also includes a limited-slip differential, sports suspension, bigger brakes with red, yellow or orange-colored brake calipers and a choice of alloy wheels in sizes up to 20-inches.

On the appearance front, the BMW M Performance catalog for the 4-Series contains black trimmed kidney grilles, a front splitter, exterior mirror caps, as well as a rear spoiler in carbon, a diffuser for the rear apron, side skirt decal strips with M Performance lettering and BMW M Performance side stripes.

For the cabin, there’s a sports steering wheel with red center marker or Race Display in the 12 o’clock position together with a carbon gearshift lever and handbrake lever grip (including Alcantara gaiter), trim strips in carbon and Alcantara, stainless steel pedals and matching driver’s footrest and floor mats.
