KIA revealed the new Optima mild hybrid show car at the 2014 Paris Motor Show this week.
This is the first demonstration of Kia’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.
Lead-carbon batteries were chosen for the mild hybrid powertrain as, unlike lithium-ion batteries, they require no active cooling and are easier to recycle at the end of the unit’s lifecycle.
