Characteristic design elements leave no doubt that this car is the work of BMW M.

Just in time for the summer, BMW unveiled the all-new M4 Convertible, powered by the same BMW M TwinPower Turbo 3.0-liter inline-six as its siblings, the M3 Sedan and M4 Coupe. That engine produces 425 horsepower and 406 lb-ft of torque and can be mated to either a 6-speed manual or 7-speed M-DCT transmission. The new BMW M4 Convertible makes its world debut at the 2014 New York International Auto Show.

BMW M4 Convertible's Exterior Lines

Viewed from the front, the BMW M4 Convertible stands out most prominently with its powerful contours and a strongly defined three-dimensionality, which lends it a powerfully expressive face. Characteristic design elements leave no doubt that this car is the work of BMW M. There is the modern take on the twin headlight arrangement (with optional LED technology), for example, not to mention the distinctive twin-bar kidney grille with black painted grille bars - which reflect the design of the characteristic BMW M double-spoke wheels and bear the M logo - and the powerfully designed front apron with its trio of large intakes supplying cooling air to the high-performance engine and brakes.

Among the other hallmark BMW M design features on display is the characteristic power dome on the hood, which hints at the potential of the brawny M TwinPower Turbo engine and creates space for the intercooler. And the striking exterior mirrors, with their suggested twin-stalk mounts, optimize the aerodynamics of the new BMW M4 Convertible.

Flawless Ergonomics Inside

Climbing into the BMW M4 Convertible, drivers will be greeted by an interior architecture complete with unimpeachable ergonomics and clear driver focus. In keeping with its character, however, the interior fulfils an even more sharply defined sporting brief. To this end, the host of traditional BMW M equipment details includes M door sill finishers, an M driver's footrest, M gearshift lever, M-design circular instruments with white graphics, M leather steering wheel with chrome trim, color contrast stitching and electroplated-look shift paddles (if the M-DCT gearbox is specified).

The front seats also represent an evocative expression of BMW M's motor sport genes. Taking visual inspiration from the bucket seats fitted in racing cars, the seats feature a full-size single-piece back panel. This means the construction of the seats is very flat, while the high, width-adjustable side bolsters and low-set seat surface allow an ideal seating position and provide excellent support.

The BMW M4 Convertible stands out with an interior that is exclusive and functional in equal measure. For example, the M Sport leather multifunction steering wheel is standard, as are bucket-style M sports seats. New to this generation of Convertible are the available three-temperature neck warmers that allow for comfortable open-air driving at high speeds and low temperatures.

Drivers of the BMW M4 Convertible can look forward to piloting their car from behind a double-spoke M leather steering wheel. The M logo, chrome trim and color contrast stitching are central elements of the cabin's racing ambience. The M4 Convertible comes standard with a 6-speed manual gearbox, while the 7-speed M Double Clutch Transmission is available as an option. M-DCT allows the driver to change gears using either the selector lever on the center console or the shift paddles mounted on the steering wheel.
