Has Koenigsegg Made The World's Fastest Shifting Transmission?


How The Koenigsegg Jesko's Light Speed Transmission Works

How Koenigsegg's 7-Clutch LST Work - Sponsored By AutoTempest
The Koenigsegg Jesko is a marvel of modern engineering. With a 5.0L twin-turbo V8 engine, it produces 1600 horsepower on E85 fuel. That's just the start. Power is sent through a 9-speed, 7 clutch transmission. Why on earth would a transmission need 7 clutches? For insanely fast shifts, from any gear to any other gear, that is. According to Koenigsegg, the clutches can open and close in as little as just 2 milliseconds! The setup uses three shafts and compound gearing to make it all work, resulting in less gear pairs overall. With a clutch for each gear pair, shifts are not only insanely fast, but there's never a loss of torque during upshifts either, as the clutches overlap while closing and opening, meaning you'll retain positive torque during the shift. Check out the video to learn all about how it works!

    Most of the ware is taken by the clutch plate, so common sense says that the more clutches the more ware. Although they are in an oiled state all the time, the temperature of that oil is going to rise quite fast so the clutch plates too are going to heat up, this maybe O.K. for racing cars but for road use there are a heap more parts to wear out a lot quicker. Therefore the original auto gearbox is much prefered out of all the systems, C.V.T.has already proven to be prone to breakage of the drive belt which on breaking releases a load of metal sections loss in the gearbox as both Ford and Honda have found out, There is an auto transmission that has proven to be good and long lasting that is the pre select gearbox used in buses and in some of the more costly cars of the past, i.e. the Daimler1937 had pre select and proved its durability by still being compleately reliable still in the seventies. Taking into consideration that machining has become greatly improved then making this form of transmission would surely be a worthwhile idea to put into modern cars???

    What's the difference between this and the kick-down (6th gear to 3rd gear under acceleration) experienced by automatics (Audi, Merc, BMW)? How did they do this kick-down without having 7 clutches like the Jesko? Genuinely interested, not a troll...

  • Kyriaeus

    All modern planetary automatics use multiple clutch packs in combination to engage each gear, and all of them are able to do any single or double shift with a single swap (1 clutch pack engages while another disengages). Most of them also have large direct jumps like how the ZF8 can skip 8-2, or how the Honda 10AT can skip 10-6 and 7-3. If they need to do an even bigger jump that just means doing multiple swaps (e.g. 2 clutch packs engage while 2 disengage).

  • KK Playz

    but some inspiration from koenigseggs lst. THe thing is you can switch from gear one to any gear you want but if you want to go straight from gear one to the highest one, why not just make a special transmission in which it works similarly to koenigseggs lst but you don't need to go to all the gears
