Geneva Motor Show: New hybrid system and dual-clutch gearbox cut carbon at Kia

By / 7 years ago / Latest News / No Comments

The seven-speed dual-clutch transmission will replace Kia’s existing six-speed automatic, sold on the majority of its model range, and is claimed to offer a 5% improvement on 0-62mph sprint times while achieving a 7% fuel efficiency uplift.

Launching in 2015, the transmission is designed to offer high refinement and a quicker, sportier gearchange than outgoing units, while the seven gears improve both performance and economy.

A new hybrid system is also due for an imminent launch, boosting power and economy by 15% and allowing all-electric driving using a small electric motor.

Developed in Germany, the system comprises a 48-volt lead-carbon battery and motor-generator, the latter offering regenerative braking while decelerating, functioning as the engine starter and alternator and providing power while cruising or at low speeds.

Kia said lead-carbon batteries are being used as they require no active cooling, function more efficiently in sub-zero temperatures and can be recycled more easily at the end of the vehicle’s life cycle.

In more powerful applications the system can also be equipped with an electric supercharger to increase torque and power at low engine speeds, assisting a larger turbocharger for higher revolutions.  

Kia said the system will be fitted to new diesel and production cars in the near future.
