The JUBU DCT-System (Dual Clutch Gearbox) transforms every Exige/Evora/3-Eleven/Emira into a spectacular daily-driver-tracktool. It combines full and comfortable street capabilities and whithin the blink of an eye (just press one button) you can drive it on track like a race-car with a sequential gearbox. Besides the full daily-driver and track-tool capabilities another advantage is the very low maintainance-cost (sequential gearbox: full revision after 30-50 hours on track; JUBU DCT: no revision needed). So the running costs are very low and concerning the JUBU DCT-System non existant.

 

Automatic mode
In automatic mode, the JUBU-DCT shifts as smooth as butter. This mode is intended for relaxed cruising in everyday driving.

 

Manual mode
The manual mode of the transmission is designed for sporty driving on the road as well as for use on the racetrack and gives the vehicle an enormous performance boost thanks to ultra-fast gear changes. The gears are shifted via paddles on the steering wheel and the gear changes are almost as fast as with a sequential gearbox. The JUBU DCT thus offers the main advantages of a sequential gearbox (ultra-short shift times), but without its disadvantages such as: the higher maintenance costs (sequential gearbox: revision approx. every 30-50 operating hours; JUBU DCT: revision-free) or the often difficult starting or the limited suitability for everyday use.

 

The JUBU DCT therefore combines the best of both worlds: full everyday suitability with the option of comfortable cruising in automatic mode and a manual mode with ultra-fast gear changes. The DCT transmission can certainly be ridden on trackdays, but for pure racing and frequent, tough trackday use, the sequential JUBU transmission naturally remains the measure of all things.

 

Our DCT-System is based on the technology of a huge global player in car manufacturing (more than 10000 units sold per year), this is why we can grant a 2-year-warranty without mileage-limit on our system. 

 

The JUBU DCT is fully and seamless integrated in the OEM-Lotus-Systems of your car.
