Korea's Kia showcases a new diesel-electric powertrain on the Optima T-Hybrid Concept at the 2014 Paris Motor Show. It pairs a 1.7 liter CRDi diesel featuring a regular turbocharger and an electric supercharger with a small electric motor powered by a 48V lead carbon battery.

The car can be driven in electric-only mode at low speeds and when cruising. Deceleration will charge the battery.

"Demonstrated for the first time in the Optima T-Hybrid, the technology will lower the total cost of ownership of our cars, yet still keep them affordable as an outright purchase for customers," said Michael Cole, Chief Operating Officer of Kia Europe.

"The new mild hybrid system is our flagship technology for improving the efficiency of our internal combustion-powered models. In future, technology such as this will help Kia further reduce fleet emissions in Europe," added Cole.
