The BMW 4-Series comes in Coupe or Convertible body styles, with rear- or all-wheel drive, and with a choice of four- or six-cylinder engines and six-speed manual or eight-speed automatic transmissions. As of the 2014 model year, prices ranged from about $42,000 for the base 428i Coupe to just less than $50,000 for the all-wheel-drive 435xi. Convertibles were priced from just below $50,000, and can be configured beyond $60,000.
The optional navigation system has the latest version of BMW's iDrive, the roller-controller system that's now flanked by a host of buttons, augmented by voice controls, and layered with a touch-sensitive surface on the controller letting drivers write out text such as addresses with fingertips. It comes with real-time traffic data, and can be teamed with a data subscription adding Google search capability. It's a system that's grown many layers to the original, austere version that relied only on a rotary knob--and lots of spinning and clicking--but it remains a maze of functionality that takes a few weeks to truly understand and customize.
Just as it does on the 3-Series sedans and wagons and hatchbacks, BMW groups the 4-Series into trim lines also, giving buyers a choice of M Sport, Sport, and Luxury themes. All come with the usual Bluetooth connectivity, power windows/locks/mirrors, and automatic climate control.
The Luxury package adds upgraded leather in the cabin, a choice of three interior wood trims, unique color combinations, and exterior high-gloss chrome accents. The Sport line replaces the chrome with high-gloss black exterior cues, red-stitched leather in the interior, and red highlights in the instrument cluster, among other upgrades. The M Sport line gets a unique M aerodynamic kit, an optional exclusive Estoril blue exterior color, Shadowline exterior accents, an anthracite headliner, sport seats, and an M-themed appearance.
Other major options on the 4-Series include a color head-up display; active cruise control; a collision warning system; and a sport suspension and sport brakes with blue calipers, the latter as upgrades to the M Sport package.
For 2015, Bluetooth audio streaming is now standard, and the so-called Enhanced Bluetooth (with a USB port) is now a standalone $500 option, Fineline Anthracite wood trim is now widely available, and Oyster Dakota leather is offered outside of the Sport line and included in Premium Package models.There are a number of other packaging changes for technology options.
