German tuner Kelleners decided to improve the looks of the 4 Series Coupe even more. Starting with the factory available Sport Package, the German engineers and designers at Kelleners added a matching front apron for all the BMW 4 Series variants. The aggressive front lip offers very little ground clearance in exchange for a dynamic look and increased downforce on the front axle.
The redesigned front end resembles the BMW 4 Series Coupe Concept revealed at Detroit Auto Show in 2013.
In addition to the front apron approach which is made of fiberglass and costs 559 euros, Kelleners also offers a number of other tuning components for the BMW 4 Series models, starting with exterior mirror caps in carbon fiber through enhanced performance and various leather interior trim.
The two 184-hp four-cylinder models 420i and 420d now deliver 215 hp while the more powerful petrol engine in the 428i outputs 287 h, up from 240 hp in standard form.
In the 430 model, the Kelleners KS Diesel Power 30 package provides 302 hp. The top dog, the 435i Coupe delivers 358 hp from the factory 300 hp.
The offer is completed by Kelleners with various light-alloy wheels in 19 and 20 inches.
