BMW i3s and MINI PHEV are from two different worlds.
Fully Charged's Jonny Smith recently test drove two plug-ins made by the BMW Group - the sporty version of the i3, the BMW i3s and the MINI with a long name, the MINI Cooper S E Countryman ALL4.
Well, not only is the approach to names is different. The BMW i3s is a ground-up built electric car that looks more futuristic than ordinary cars (especially in late 2013 when it was introduced). On the other hand, the MINI is a plug-in hybrid built on the base of the conventional version and is way more conservative.
Performance of both are similar. i3s does 0-60 mph in 6.8 seconds, while the MINI Cooper S E Countryman ALL4 in 6.7 seconds and offers all-wheel drive, by the way.
Jonny Smith's choice would be the i3s, because it's a proper driving machine. And just recently the i3/i3s received a major upgrade in form of 42.2 kWh battery, available from November/December in first few markets in Europe.
