Previewing a production model that will "add a new dimension to the qualities of the BMW 3 Series Coupe in terms of aesthetics, dynamics and elegance," the BMW Concept 4 Series Coupe is set to make its formal public debut at the upcoming Detroit Auto Show in January. The volume-build version of this rakish 2-door -- which is expected to be a near clone of the Concept 4 Series Coupe -- goes on sale here in mid-2013 as the replacement for the current 3 Series Coupe in the automaker's lineup. While we're still left to speculate on the powertrain specifics of even the Concept, the automaker has provided a comprehensive download on its exterior and interior styling elements.
The longer/lower/wider philosophy is clearly in evidence here, giving the Concept 4 Series Coupe a considerably more dramatic presence than its existing 3 Series counterpart. While retaining the traditional long-nose/short-tail proportions and trim front/rear overhangs, the Concept 4 is 0.8-inch longer and 0.6 inch lower but boasts nearly two inches of additional wheelbase coupled with wider front/rear track dimensions, all stats that should enhance the dynamic character and passenger-pleasing potential of production 4 Series models.
Painted Liquid Metal Silver, the Concept 4 Series Coupe's even-more-dramatically contoured sheetmetal is set off with a bevy of equally profile-popping details. A bolder front fascia treatment complements the BMW signature twin-kidney grille with larger air intakes, hexagonal full LED headlamps and aero-abetting Air Curtain channels in the front apron while the car's side view matches a flowing roofline and sporty C-pillar treatment with 3 Series-style double swage lines and pronounced fender flares that house exclusive 3D-look 20-inch alloy wheels wrapped in high-performance rubber. As a final functional flourish, the Concept 4 introduces a new touch, the "Air Breather." Situated on the front flanks this operational exit port works in concert with the Air Curtain to effectively reduce drag around the wheels. The rear quarters on the Concept 4 Series make a similarly strong visual statement, combining L-shaped LED-infused taillamps and an aggressive fascia form, complete with lower diffuser that integrates prominent dual exhaust outlets.
Inside, the Concept 4 Series Coupe displays a parallel kind of focused overall enhancement, highlighted by various custom touches from the BMW Individual division. Enriched with Natural Chestnut wood trim, the car's driver-centric cabin combines user-friendly instrumentation and control layouts with a "layered" motif aimed at maintaining an elegant sense of proportion. Supportive front buckets are matched with well-contoured rear perches that have the look of twinned individual seats while premium Black and Schiaparelli Brown leather with hand-braided leather accenting appears throughout the passenger compartment. Although some of the Concept's more esoteric trappings are destined to go the way of all one-off exercises, many of the basics are expected to carry over to the production 4 Series, both in the Coupe and in a BMW 4 Series Convertible variant that will follow in fall 2013.
