Kia appeared at the Geneva International Motor Show with two plug-in hybrid versions of already known models: Optima Sportswagon and Niro.
Kia Optima Sportswagon Plug-in Hybrid is equipped with the same efficiency powertrain that's also found in the Optima Plug-in Hybrid sedan, meaning it's powered by a 2.0-litre 'Nu' four-cylinder GDI engine, generating 156 ps and 189 Nm; it's assisted by the transmission-mounted 50 kW electric motor, applying power through a six-speed automatic gearbox.
The powertrain's total power output is 205 ps at 6,000 rpm, with a high torque output of 375 Nm (276 lb ft) from just 2,330 rpm, which is enough to provide acceleration from 0-to-100 kph in 9.7 seconds.
The new model is said to emit just 34 g/km CO2 (combined, NEDC), however final electric range and CO2 emissions figures are expected to be published closer to the car's on-sale date. Powered by a 11.26 kWh lithium-polymer battery pack, Optima Sportswagon provides a provisional pure-electric range of more than 60 km (38 miles) at speeds of up to 120 kph.
An important piece of information is also the fact that the new model offers 440 litres (VDA, with rear seats in upright position) of cargo space, which is 133 litres more than the Optima Plug-in Hybrid sedan. It can be increased to 1,574 litres.
Kia Niro PHEV, which is expected to become available in Europe this fall, features practically the same powertrain as the hybrid Niro, however it includes a more powerful 44.5 kW electric motor (offering almost 40% more power, up from 32 kW). The total power and torque output for the Niro Plug-in Hybrid's powertrain will be 141 ps and 265 Nm, enabling the new model to accelerate from 0-to-100 kph in 10.8 seconds, making it 0.7 seconds quicker than the standard Niro.
Paired with 1.6-litre GDI (gasoline direct injection) engine is a 8.9kWh high-capacity lithium-polymer battery pack (Niro 1,56 kWh) that can store enough energy to allow over 55 kilometres of zero-emissions pure-electric driving rang.
Emissions are also reduced compared to the more conventional Niro hybrid, officially targeting at below 30 g/km (combined, New European Driving Cycle), while Niro pinned 88 g/km.
