According to Forbes in no particular order;
BMW i3
The EPA’s fuel economy champ for 2015, the compact i3 comes
wrapped in oddly polarizing styling
and is so much more, and in many ways less,
than an electric 3 Series. It puts the equivalent of 170
horsepower to the
pavement, with (as is the case with all EVs) 100 percent of the electric
motor’s
torque available immediately, which makes it feel peppier than
expected. Its expected range is 80-100
miles on a charge, which can be
accomplished in as little as six hours depending on the type of
charger and
electrical supply. An optional DC Combo Fast Charger is capable of restoring
the
battery to 80 percent capacity in about 30 minutes when connected to a
Level 2 public charging
station. This is also the only EV to offer an optional
extended range gasoline engine to run the
electric motor once the car’s
lithium-ion battery is depleted, though a tiny gas tank means frequent
full-ups
to keep going indefinitely.
