M31
Intense Performance.
Luxury Ride.
The Everyday Exotic.
When performance and luxury collide, the result is the DCB M31 Widebody—a stunning, mid-size exotic supercat that delivers the perfect balance of aggressive speed and everyday drivability. Sharing the same elite DNA as its larger M-Series siblings, the M31 delivers exhilarating performance, precise handling, and the unmistakable refinement that defines every DCB.
Raw Power
Under the hatch, the M31 is powered by your choice of Mercury Racing 565, 600, 700 or the ultimate 1100 twin-engine stern drive packages—each delivering breathtaking performance, torque-rich acceleration, and proven reliability at the highest levels. Whether carving glass or running across open water, the M31 responds with sports car-like precision and high-speed confidence.

Built on a widebody platform for enhanced stability and space, the M31 offers seating for six and a cockpit experience designed around both adrenaline and comfort. With its aggressive lines, sculpted wraparound windshield, and handcrafted interior, every detail of the M31 reflects the flawless design and build quality that sets DCB apart.
