Kia will reveal the new Kia Optima mild hybrid show car at the 2014 Paris Motor Show on 2 October, the first application and demonstration of the brand's innovative new mild hybrid powertrain.

The Kia Optima T-Hybrid (turbo hybrid) concept is powered by the model's existing 1.7-litre CRDi turbo-diesel engine, paired with a small electric motor, powered by a 48V lead-carbon battery. The diesel-electric powertrain concept, which was previewed at the 2014 Geneva Motor Show, enables the Optima T-Hybrid show car to be driven in electric-only mode at low speeds and when cruising, with deceleration serving to recharge the battery pack.
