Named and styled after the infamous shark species, the BMW Bullshark from Bulgarian design studio Vilner represents as a complete overhaul of the 645 Ci.

The eye-catching exterior includes a sharper looking front end with a pencil-mustache style kidney grille and the Infiniti FX-sourced headlamps, the heavily creased front and rear fender extensions and the side gill design. Only the roof and original doors have remained unchanged.  The tail-lamps were taken from the facelifted 6-Series E63, while the coupe rolls on 19-inch wheels with a staggered setup.

As for performance, AC Schnitzer provided a software kit to lift the 4.4-liter V8 mill's output from 329HP (333PS) to 365HP (370PS) and peak torque to 522Nm (385 lb-ft), which helps improve the 0-100km/h (62mph) sprint time to 5.4 seconds and increase top speed to 278km/h (173mph).  Vilner will also be designing an individual traveling bag for the lucky new owner of the car.
