The project was managed by Bentley's head of design, Luc Donckerwolke.

The Speed 6 retains Bentley's signature dual round full-LED headlamps, but the main headlamp is almost an oval-shape, but when seen from head-on it appears to be perfectly round.

The Speed Six was Bentley's first two-seater, and it featured an aerodynamic design with many different creases and lines in its body, and Bentley's signature "Flying B" design element has been the inspiration for the b-shaped crease on the Speed Six's side panels and doors.

For a car of its class, it features an unprecedented amount of leather, wood veneers, bespoke options, and interior appointments compared to its potential rivals including the Lamborghini Huracán, Jaguar F-Type, Porsche 911, Ferrari California, and others.

The Speed Six would eventually inspire the design language of the most recent Bentley products, most notably the 2018 Continental.
