A new 30kW battery in the Nissan Leaf will go on sale in December, delivering a claimed range of 155 miles.
It will go on sale alongside the 24kW unit but will only be available in Acenta and Tekna trim, priced from £24,490 to £27,940 including the UK government’s £5000 Plug-in grant, which was recently extended until February 2016.
Nissan is also increasing its warranty for the 30kW unit to an eight-year, 100,000-mile warranty.
The new battery brings an increase in range of around 25% over the alternative 24kW unit, according to Nissan. It has the same dimensions as the lesser-powered unit but is 21kg heavier. The manufacturer says this longer range is the result of the introduction of carbon, nitrogen and magnesium to the electrodes in the new unit.
Nissan expects the real-world range of the new battery to be around 12-15% less than the claimed 155 miles, representing a similar loss to the 24kW unit. This would put the new battery's real-world range at around the 135-mile mark.
In Acenta and Tekna trims, the 30kW Leaf comes with a 7.0in touchscreen and the smartphone-compatible Nissan Connect EV infotainment system, which allows users to check the charge status of the car and remotely control features such as the air-con. The system the previous Car Wings set-up.
The new infotainment package includes a charging map that can show which charging points are available and which are being used. It also delivers maintainance alerts and a car-finder facility.
