BMW was the top selling luxury brand in the U.S. last year, and it’s now stepping up its efforts to indulge affluent buyers by showing off a prototype of a new BMW 4-Series that is longer, lower, leaner, and more elegant than the company’s ever popular 3-Series Coupe. The styling gives the car a very dramatic presence and features a new interpretation of the iconic BMW grille. The 4-Series concept’s interior features tanned leather and wood trim made of Chestnut, which enhances the cars contemporary aesthetic appeal. BMW was quick to note that the driving dynamics and powertrain in any production version would exceed anything offered by the competition in the premium price range. Estimated price is $50,000 to $55,000.
