The Focus Electric is Ford's first all electric passenger vehicle. From the Focus Electric website:
"Powered exclusively by a lithium-ion battery system, the 2013 Ford Focus Electric has a city fuel efficiency rating of 110 MPGe. That’s the best city rating in its class."
"The Focus Electric gets all of its power from an advanced state-of-the-art 23kWh liquid-cooled, high-voltage lithium-ion battery system. It gives you a best-in-class range of up to 76 miles on each charge."
Ford's biggest competitor for the Focus Electric is the Nissan Leaf.
From Car and Driver's report on the Focus Electric with some nice comparisons to the Nissan Leaf:
"That said, the electric Focus is no stoplight king. A 141-hp AC motor sits between the front wheels and offers 188 pound-feet of torque at all times. The motor works against 3612 pounds of mass through a single-speed transaxle. Acceleration has the slow grace of a Lincoln Town Car. We clocked a 0-to-60-mph time of 10.3 seconds, a few tenths off the less powerful, nearly 235-pound-lighter Leaf. Remember 85-mph speedometers? The electric Focus could barely peg one; top speed is reported to be governed at 84 mph, but we managed 85 with our test vehicle. The Focus Electric covers a quarter-mile in 17.9 seconds, reaching 80 mph at that same time."
"According to EPA tests, the Ford EV has a range of 76 miles on a single charge; on the same test, the Leaf scores 73. The Focus is slightly more efficient than the Leaf and returns a combined mileage number of 105 MPGe (miles per gallon equivalent) compared with the Leaf’s 99. That means the electric Focus can travel 100 miles for about 25 cents less than the Leaf. We saw 94 MPGe in our short test, and managed an 83-mile range on a trip that was roughly half city and half highway driving.
Another advantage for the Ford is that recharging the Focus’s 23-kWh lithium-ion battery from empty takes three to four hours on 240-volt power, or nearly half the time required for the Leaf (although we hear that Nissan will be upgrading the car's onboard charger for quicker refills soon). On 120 volts, a full charge of the Ford takes about 20 hours. Ford credits the battery’s highly effective cooling system for this. Unlike what Nissan offers for the Leaf, Ford isn’t making available a quick-charge 440-volt plug on the Focus, but there is less need for one."
