Dubbed the Cigarette AMG Electric Drive, this speed racer was developed by Mercedes-AMG in collaboration with Cigarette Racing and recently unveiled at the Miami International Boat Show
Numerous components from the SLS AMG Coupè Electric Drive have been integrated in the design of the Cigarette, the high-performance drive fitted in the electric super sports car makes the off-shore powerboat the world’s most powerful and fastest electrically driven motor boat. With an output of 1656 Kilowatts (2,220hp) and a maximum torque of 3000 Newton metres (2,213 ft-lb,)
The 38 foot (11.6 metre) long powerboat is finished in AMG Electricbeam magno – the matt chrome paintwork exclusively reserved for the SLS AMG Coupe Electric Drive The design features also exemplify the transfer of technology from the gullwing to the powerboat. Mercedes-AMG uses two drive units, each featuring six independent electric motors. At the rear of the boat, each drive unit has its own transmission, the boat is fitted with the twelve compact, liquid-cooled permanent-magnet synchronous electric motors.
Each electric motor delivers 138 kW and 250 Newton metres. The maximum output of 1656 Kilowatts and maximum torque of 3000 Newton metres combine to reach a staggering top speed of over 160 km/h making this the world’s fastest electrically driven powerboat.
The liquid-cooled lithium-ion battery has a maximum voltage of 400 V. It consists of 12 modules each comprising 72 lithium-ion cells. Cigarette integrates four high-tech batteries with a total of 48 modules and 3456 cells which generate a total capacity of 240 Kilowatt hours and an electric output of 2400 Kilowatts.
The boat is fitted with two 22-Kilowatt on-board chargers from the SLS AMG Coupe Electric Drive as standard. Adapted to fit the infrastructure standard of many American marinas, the boat has a charging capacity of 44 Kilowatts. The battery is fully charged in approximately seven hours. To reduce the charging time to less than three hours, the powerboat can be fitted with four on-board chargers as an option.
Onboard the racing sports seats are matched with various carbon fibre composite elements in the cockpit. The display concept of the SLS AMG Coupe Electric Drive can also be found behind the steering wheel: fitted with dials in the exclusive “AMG Electricbeam magno” paint finish and sporting AMG logos, the displays provide information about the current motor output, the speed, battery voltage and of course the battery’s state of charge.
