What has Nissan done now?
As part of its 2016 model year update, Nissan has given potential buyers of the Leaf electric car the option of a better battery that will enable a longer driving range compared with the current (no pun intended) model.
How has it managed that?
Here comes the science part. In order to create this new 30kWh battery, Nissan's engineers have rearranged the cell layout but have also added carbon, nitrogen and magnesium to the electrodes inside, all of which creates improved performance.
What's the result?
Even though much of the new battery's construction has changed, the overall size hasn't so there's no impact on interior space. What has increased is the weight of the battery, by 21kg, but in spite of that the driving range now stands at (up to) 155 miles.
Any other changes for 2016?
Yes, Nissan has updated its Carwings smartphone app that lets owners check the status of their car as well as perform tasks remotely such as turning on the car's climate control prior to setting off in the morning.
There is also a new user interface via a seven-inch touchscreen along with a new digital radio receiver. A new exterior colour, Bronze, has also been added to the existing palette.
Will this replace the old battery?
No, Nissan is going to continue selling the existing 24kWh battery on Visia, Acenta and Tekna grade Leafs, with prices starting at £20,790. The 30kWh battery will be available on Acenta and Tekna grade Leafs where pricing will start at £24,490.
