Sequential 7-Speed-Gearbox

KT-7 Speed Sequential Manual Transmission (7-speed)

Lotus uses either a manual 6-speed manual transmission, or a torque converter automation in the IPS-Spec of the Lotus Exige.

In the case of ambitious driving, a major disadvantage of a classic gearbox is the shifting process per se, the needed shift-time, including missing torque and in addition, the resulting possibility of faulty operation.

The torque converter has the disadvantage of less efficiency and thus friction losses, slow shifting times and it is very heavy-weight.

The Komo-Tec 7-speed sequential gearbox is what will separate your Lotus from the rest of the pack! The gearbox was developed following a strong demand from Lotus-drivers needing to gain the additional performance that factory part cannot deliver. The non-synchronized, straight gearing is for a gearbox of this design surprisingly low noise while normal driving.

The main advantages are obvious:

faster acceleration,
higher strength (rated up to 900 Nm)
lightweight (only 58.5 kg)
quicker shifts (flatshifting of gears as little as 40 milliseconds)
a range of optional ratios (5 different options are available for Max-Speed: 274, 212, 252, 231, 297 km/h)
Another advantage is:

The transmission is specially designed for the Lotus Exige V6 and Evora and therefore has the advantage that the original driveshafts, couplings and brackets can be adopted without any modifications (on the engine side). The installation is therefore faster and cheaper

than with other sequential gearboxes that has been developed as universal transmissions. Universal oil coolers and / or an oil temperature sensor can also be added as an option (surcharge).

Unique to this type of transmission is an externally adjustable differential nut. The maximum adjustment is 13kg and it is possible to customize the ramp angle of the differential lock to customer requirements. The standard ramp angles are 53/0 and 40/0.

Depending on customer requirements, we can provide a very short close ratio gearbox for you or you are chasing the 300 km/h. So there is an option for everyone that is right.

It is very helpful to use the sequential Gearbox in conjunction with our Alloy Flywheel and Sinter-Metall Clutch:
