Its design integrates numerous components from the SLS AMG Coupé Electric Drive.
Wearing AMG logos on the side, the powerboat uses two drive units, each featuring six independent electric motors. At the rear of the boat, each drive unit has its own transmission, one on the left and one on the right.
The twelve compact, liquid-cooled permanent-magnet synchronous electric motors which are the signature piece of the SLS AMG Coupé Electric Drive: each electric motor delivers 138 kW and 250 Newton meters.
The maximum output of 1656 Kilowatts and maximum torque of 3000 Newton meters combine to reach a staggering top speed of over 160 km/h making this locally emission-free “Cigarette AMG Electric Drive Concept” the world’s fastest electrically driven powerboat.
The low centre of gravity and optimum weight distribution ensure high-level handling characteristics during more dynamic changes of direction.
The 38 foot (11.6 metre) long “Cigarette AMG Electric Drive Concept” powerboat is finished in “AMG Electricbeam magno” – the same matt chrome paintwork exclusively reserved for the SLS AMG Coupé Electric Drive.
The lithium-ion high-voltage battery
The high-voltage battery in the SLS AMG Coupé Electric Drive boasts an energy content of 60 Kilowatt hours, an electric load potential of 600 Kilowatts and a weight of 548 kg.
The liquid-cooled lithium-ion high-voltage battery features a modular design with 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 – benchmark figures that earn respect even in the boat building industry.
The battery is the result of the cooperation between Mercedes-AMG GmbH in Affalterbach and Mercedes AMG High Performance Powertrains Ltd.
The “Cigarette AMG Electric Drive Concept” is fitted with two 22-Kilowatt on-board chargers from the SLS AMG Coupé 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.
Interior Design
The signature Cigarette Racing sports seats are matched with various carbon elements in the cockpit.
The display concept of the SLS AMG Coupé 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.
