The 2015 BMW M4 is a two-door, four-passenger high-performance car available in coupe or convertible body styles, based on the company's 4 Series.
The M4 includes 18-inch alloy wheels with summer tires, adaptive xenon headlights, auto-dimming mirrors, leather upholstery, heated 10-way power front seats (with four-way power lumbar), driver memory settings, fold-down rear seats, cruise control and dual-zone automatic climate control. Technology features include Bluetooth phone and audio connectivity, an 8.8-inch display screen, a navigation system, a suite of smartphone and online applications under the BMW ConnectedDrive banner, BMW's iDrive controller interface and a nine-speaker audio system with HD radio, a USB/iPod interface, an auxiliary audio jack and a CD player.
An optional Executive package adds headlight washers, front and rear parking sensors, keyless entry and ignition, a head-up display, a heated steering wheel, a rearview camera and satellite radio. The Lighting package further adds adaptive LED headlights and automatic high-beam control. The Driver Assistance package gets you blind-spot monitoring, lane-departure warning, a side- and top-view camera system, speed limit info, frontal-collision warning and automatic braking for collision mitigation.
Some items within the bundled packages are available as stand-alone options. Other stand-alone options include 19-inch wheels, upgraded carbon-ceramic brakes, adaptive suspension dampers, automated parallel-parking assist, extended- and full-leather treatments, a power rear sunshade, enhanced smartphone connectivity and a 16-speaker Harman Kardon surround-sound audio system.
On the coupe, you get your choice of either a visible carbon-fiber-reinforced-plastic (CFRP) roof or traditional steel roof with sunroof. In place of that roof, the M4 convertible has a power-retractable hardtop with a wind blocker, as well as extended leather upholstery and door trim that incorporates sun-reflective technology. When equipped with the Executive package (see above), it also includes front-seat neck warmers.
