Kia has added the Niro and Optima plug-in hybrids to its UK line-ups.

Kia Niro PHEV

Launched a year after the standard hybrid Niro, the PHEV version of the crossover features the same 1.6-litre direct-injection petrol engine married with a more powerful 44.5kW (60bhp) electric motor. It offers an electric-only range of 36 miles and brings a claimed fuel consumption of 217.3mpg and emissions of 29g/km – putting it in the 9% BiK bracket for 2017/18.

Prices start at £27,995 OTR (including the Plug-in Car Grant).

Kia has also opened order books for the PHEV version of its Optima Sportswagon, which joins the saloon model already on sale. As with the Optima saloon PHEV, the Sportswagon PHEV combines a 154bhp 2.0-litre direct-injection petrol engine with a 50kW (67bhp) electric motor. However, the estate model features increased storage capacity of 11.26kWh in the lithium-ion polymer batteries (compared to 9.8kWh) giving it a longer all-electric range, lower CO2 emissions and better fuel economy, which stand at 38 miles, 33g/km and 201.8mpg compared to 33 miles, 37g/km and 176.6mpg for the saloon.

The Optima Sportswagon is priced at £32,645 (including the Plug-in Car Grant) with the saloon model already on sale at £31,495.
