Because the automaker’s first four-seater, the Koenigsegg Gemera proved to be an engineering problem not solely by way of efficiency, however packaging, as CEO Christian von Koenigsegg explains in a video concerning the Gemera’s drivetrain.
The Gemera makes use of a variation of the Gentle 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 rapidly as attainable.
Referred to as the Gentle Pace Tourbillon, the Gemera’s transmission was developed with classes discovered from the Jesko, and carries over lots of the identical internals. However it needed to be repackaged to suit into the again of the four-seat Gemera with out compromising passenger or cargo house.

Koenigsegg’s resolution was to basically 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 sequence of clutches, which additionally offered torque vectoring and remove the necessity for a differential. This association permits retains the crankshaft peak under the wheel centerlines, decreasing the automotive’s heart of gravity.
The Gentle Pace Tourbillon nonetheless has 9 ahead gears just like the Jesko’s Gentle Pace Transmission, however as a result of it was designed to be used with a hybrid powertrain, there isn’t any reverse gear. That is dealt with by the electrical motor on the entrance axle. That single motor may also energy the rear wheels as effectively 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 supposed 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.
