Vauxhall has extended the range of the Corsa-e and all-new Mokka-e after finding greater efficiencies in heating, transmission and tyres.
The manufacturer says that on a single charge of its battery, the Corsa-e can now cover up to 222 miles (WLTP), up from 209 miles previously, an increase of around 6%.
The range of the Mokka-e, meanwhile, has increased to 209 miles (WLTP), up from 201 miles previously, an increase of around 4%.
Vauxhall says that the range increases have been achieved through the optimisation of the HVAC (Heating, Ventilation, Air Conditioning) and propulsion systems of the Corsa-e and Mokka-e.
The efficiency of the heat pump, which warms and cools the interior and is standard equipment on both models, has been improved.
Heat pumps are more efficient than conventional HVAC systems, as they require less energy from the battery, to the benefit of driving range.
Customers will notice the improvements particularly when driving in the winter months, it says.
A new transmission reducer that converts the motor revs into wheel speed will also help optimise the range and in terms of tyres, an A+ rated 16-inch (Corsa-e) and 17-inch (Mokka-e) low rolling resistance tyres provide greater efficiency.
Vauxhall will offer an electrified variant across its entire model line-up by 2024 and will have a fully electric vehicle range by 2028.
Across cars and LCVs, Vauxhall already offers five fully-electric models and, following the launch of all-new Astra, two plug-in hybrid models.
