World Auto Evolution released an interesting statistics-only comparison of three electric cars, the Renault ZOE, BMW i3 and Chevrolet Bolt EV - each pitted against the other.
The first comparison is for the European market specifially: the Renault ZOE vs BMW i3. Both models were deemed winners (ZOE for the mass market, i3 for the premium market).
The Renault ZOE turns to be much cheaper, with a larger trunk and longer range (41 kWh version), while the i3 is found to be a more premium offering, with better finishes, and better performance.
The second duel is the Chevrolet Bolt EV against BMW i3.
This time the Chevrolet Bolt EV was called the winner, because of not only having a lot more range (with up to 238 miles) but because it has more power, and slightly more usable capacity.
On the plus side for the BMW i3, the plug-in still beats the Bolt EV in 'premium' aspects, and quality of materials in use.
The last comparison is for a couple all-electric cars that basically will never meet - the Chevrolet Bolt EV and Renault ZOE. Although the comparison is still valid, as in the Europe the Bolt EV will be sold as the Opel Ampera-e in the second half of the year, while in North America Renault doesn't sell cars at all.
On the specific Bolt EV to Opel Ampera-e comparison, World Auto Evolution noted much more power, battery capacity and longer range for the Bolt EV than the ZOE. However, the ZOE is considered as being much cheaper.
