While the BMW i3 REx (with a 650cc two-cylinder petrol engine serving as back-up generator) has been the primary choice in UK from the start, the introduction of a longer-range 33.2 kWh (94 Ah li-ion cells) battery version means the advantage of the extended range option on the BMW should decrease (a fact we have already started to see show in the sales splits in Europe for October), as more consumers will feel comfortable within the all-electric car's new range of 114 miles (183 km) EPA.

However, the new 2017 i3 REx has also received the same 33.2 kWh battery bump, which provides 97 all-electric miles of driving with 83 miles of petrol driving, combining together for a total range of 180 miles.

Recently, the 2017 BMW i3 REx model was reviewed by Autocar, which feels that there are still yet more practical choices when it comes to utility, like the Volkswagen e-Golf and Nissan LEAF with more rear space and larger trunk.

However, the i3's premium interior handily beats the more mainstream models when it comes to luxury, infotainment and just general driving equipment.

The problem whether or not to choose i3 or i3 REx mostly comes down to the higher price (£3000), and the higher BIK tax band, as well as slightly lower fuel economy.

On the driving experience:

  • strong performances at motorway speeds
  • eager acceleration
  • Comfort mode brings best feel
  • quiet operation, REx doesn't disturb the calm
  • ride and handling could be better
  • great low-speed agility in town
  • adults will not stand in the rear seats too long and only 260 litres trunk
