The Kia Niro Plug-in Hybrid is a petrol-electric plug-in hybrid (PHEV) with a six-speed dual-clutch automatic gearbox (rather than the more common Continuously Variable Transmission (CVT)). The combustion engine, based on a 1.6-litre Kappa direct-injection (GDi) unit and developing 104bhp, uses the efficient Atkinson cycle combustion process. There’s also a 44.5kW (60bhp) electric motor with 170Nm of torque, powered by an 8.9kWh lithium-ion polymer battery. It offers an official 36 mile all-electric range and has official CO2 emissions of just 29g/km CO2. With its ‘crossover’ body style, it’s also a practical size.
