The Koenigsegg CC850 that debuted throughout August’s 2022 Monterey Automobile Week is a re-imagination of the Swedish agency’s first manufacturing automotive, and one of many highlights is a transmission like no different.
The CC850 makes use of a model of the 9-speed Mild Pace Transmission from the Koenigsegg Jesko, however with a brand new Have interaction Shifter System (ESS) that makes the automated transmission rework right into a 6-speed guide (it nonetheless maintains the total automated mode with 9 gears, although). This Engineering Defined video offers a deep dive into Koenigsegg’s reinvented guide.
First, the mechanical variations. the ESS gearbox has a clutch pedal like a traditional guide, but it surely’s by-wire, and as an alternative of 1 clutch, the ESS has seven. These clutches deal with gear choice, eliminating the necessity for shifter forks and synchros. It additionally lacks a flywheel, so the engine connects on to the transmission.

The clutches are unfold out throughout two shafts. in automated mode, one clutch on every shaft engages to provide the facility a path to the rear wheels, whereas enabling all 9 ahead gears with out the necessity for what would in any other case be a really difficult shift mechanism. As with the clutch, the shifter is a by-wire system.
Within the CC850, the transmission will also be shifted manually by shifting a shift lever via gates, much like typical guide gearboxes, whereas urgent the clutch pedal releases all seven clutches. Engagement nonetheless requires two clutches, however on this case a place sensor on the shifter controls the primary clutch, whereas foot stress on the clutch pedal controls the second clutch.
The ratio that corresponds to every gear quantity can even change relying on the drive mode. For instance, in monitor mode the transmission will begin out with second gear’s ratio as first, however then change to 3rd gear’s ratio when you get going. That successfully tightens up the ratio unfold with out having to bodily swap out gears.Â
As for reverse, it will depend on whether or not the automotive is being pushed in automated or guide mode. The driving force makes use of the clutch pedal for guide mode, and would not for automated mode. And the transmission is aware of when the automotive is in automated mode as a result of reverse is positioned immediately above drive within the shift sample.
And whereas the clutch pedal is by-wire, with no mechanical connection to the numerous bodily clutches, it is designed to simulate the texture of an analog left pedal. That really feel is replicated by software program based mostly on parameters from a standard guide. It can even authentically stall.
Which means you get the comfort of an automated and the texture of a guide in a single transmission—one which’s lighter than a traditional guide, Koenigsegg claims. Going from 9 accessible gears in automated mode to 6 in guide mode may result in some large gaps between ratios, however even that’s handled by the tighter ratio set utilized in monitor mode. Clients do not appear frightened about any potential drawbacks; Koenigsegg has already introduced that it is upping CC850 manufacturing to fulfill sturdy demand.
