Because the automaker’s first four-seater, the Koenigsegg Gemera proved to be an engineering problem not solely when it comes to efficiency, however packaging, as CEO Christian von Koenigsegg explains in a video in regards to the Gemera’s drivetrain.
The Gemera makes use of a variation of the Mild Pace Transmission from the Koenigsegg Jesko. This 9-speed gearbox does away with synchros and a flywheel, permitting it to shift from any gear to a different even when they’re numerically out of sequence, whereas permitting the engine to rev as shortly as potential.
Known as the Mild Pace Tourbillon, the Gemera’s transmission was developed with classes realized from the Jesko, and carries over lots of the identical internals. But it surely needed to be repackaged to suit into the again of the four-seat Gemera with out compromising passenger or cargo area.

Koenigsegg’s answer was to primarily wrap the transmission across the engine. It sits between two outriggers that von Koenigsegg calls “cassettes,” which redirect energy sideways to the wheels by way of a collection of clutches, which additionally offered torque vectoring and eradicate the necessity for a differential. This association permits retains the crankshaft top beneath the wheel centerlines, decreasing the automobile’s heart of gravity.
The Mild Pace Tourbillon nonetheless has 9 ahead gears just like the Jesko’s Mild Pace Transmission, however as a result of it was designed to be used with a hybrid powertrain, there is not any reverse gear. That is dealt with by the electrical motor on the entrance axle. That single motor can even energy the rear wheels as properly for all-electric driving.
A carbon fiber prop shaft sends energy from the engine to the entrance axle, the place it is distributed to every wheel by a pair of clutches (which additionally allow torque vectoring) housed with the entrance electrical motor and its inverter in an meeting Koenigsegg calls the Bulldog due to the quantity of energy it harnesses relative to its dimension.
This drivetrain was initially meant to be used with a 2.0-liter turbo-3, which was to work with three electrical motors (together with two on the rear axle) to provide a mixed 1,700 hp. However simply forward of the beginning of manufacturing final yr, Koenigsegg introduced an out there twin-turbo 5.0-liter V-8 that boosts output to 2,300 hp. It then dropped the 3-cylinder engine, a transfer von Koenigsegg mentioned was pushed by buyer demand.
