Mercedes-AMG and Cigarette Racing launch electric powerboat

Article by Anita Panait, on March 9, 2013

Mercedes-AMG and Cigarette Racing are unveiling the "Cigarette AMG Electric Drive Concept," the latest development of their collaboration at the recently concluded Miami International Boat Show. Cigarette AMG Electric Drive Concept integrates several components from the SLS AMG Coupé Electric Drive, which is considered as the most powerful and fastest electric production vehicle in the world.

By fitting high-performance drive technology from the SLS AMG electric super sports car in a Cigarette Racing off-shore powerboat, the joint project was able to create the most powerful and fastest electric motor boat in the world -- the Cigarette AMG Electric Drive Concept powerboat.

The concept powerboat boasts of up to 1656 Kilo watts (2,200 hp) in output and up to 3000 Newton meters (2,213 ft-lb) of torque. The Cigarette AMG Electric Drive Concept powerboat measures 38 feet (11.6 meters) in length and features an "AMG Electricbeam magno" finish, the matt chrome paintwork exclusively reserved for the SLS AMG Coupé Electric Drive.

The concept powerboat bears AMG logos on the side, expressly showing the partnership between the American boat manufacturer Cigarette Racing and German performance brand Mercedes-AMG GmbH.

The engine design embodies the transfer of technology from the SLS AMG Coupé Electric Drive sports car to the Cigarette AMG Electric Drive Concept powerboat. The concept powerboat features 12 compact, liquid-cooled permanent-magnet synchronous electric motors.

Mercedes-AMG installed two drive units in the powerboat, each featuring six independent electric motors. Fitted at the rear of the powerboat, each drive unit has its own transmission, one on the left and one on the right.

Each electric motor provides 138 kW of output and 250 Newton-meters of torque. Combined, the electric motors could propel the powerboat to a top speed of over 160 km/h, thus the Cigarette AMG Electric Drive Concept the world's fastest electric powerboat. The motors and the battery are ideally placed in the "Cigarette AMG Electric Drive Concept," just like in the SLS AMG Coupé Electric Drive. The low center of gravity and optimum weight distribution assures excellent handling when changing direction.

While the design of the SLS AMG is a multi-award-winning one, this is combined with certain features that have long been exclusive to the Electric Drive version. Thus, while the front apron comes with that prominent CFRP carbon-look front splitter, this feature also helps the front axle get that needed downforce. Other features on the front section include the radiator grille while certain special areas, which are in the same color as the body, have been decorated with air intakes.

There are also the bionic openings shaped like honeycombs. While they are indeed a visual highlight, they come with function as well. Their design has been optimized to improve aerodynamics and thus enhance the air flow that goes above the cooling modules, which have been mounted behind them. With the darkened headlights, it gives the front section that sense of independence. When looked at on its side, one can clearly see the “Electric Drive” lettering.

The light-alloy 5-twin-spoke AMG wheels, which have their own exclusive design, can be seen from this angle as well. Helping the SLS AMG Coupé Electric Drive slow down are the high-performance AMG brakes made of ceramic composites. What makes the brakes excellent is that even when under extreme operating situations, the brake offers direct response, exceptional fade resistance, and even precise actuation point.

The discs are clearly over-sized with the front discs measuring 402 x 39 mm while the ones in the rear measure 360 x 32 mm. In addition to being composed of ceramic, strengthened with carbon-fiber, it has an all-around integral design. The discs are then linked to an aluminum bowl through a radially floating arrangement. Being made of ceramic, the brake discs are lighter by 40% when compared to the standard ones made of grey cast iron. Further, by reducing the unsprung masses the agility and handling dynamics are enhanced.

This also improves the tire grip and the ride comfort. In addition, the rotating masses on the front axle have been lowered allowing for a steering response that is more direct. Drivers can easily notice this when running at high speeds on motorway bends.
