The 2014 Chevrolet Spark EV (earlier post) now carries a combined city/highway EPA-estimated range of 82 miles when fully charged and an EPA-estimated combined city/highway 119 MPGe fuel economy equivalent (28 kWh/100 miles), making it one of the most fuel-efficient EVs assessed by the EPA.
By comparison, the 2013 Scion iQ EV is EPA-rated at 121 MPGe; the Honda Fit EV at 118 MPGe; the Fiat 500e at 116 MPGe; the i-MiEV at 112 MPGe; the Ford Focus Electric at 105 MPGe; and the smart fortwo electric at 107 MPGe. Other EVs on the market have combined fuel economy ratings below 100 MPGe.
The Spark EV’s 21 kWh lithium-ion battery pack carries a limited warranty of eight years or 100,000 miles, whichever comes first.
Spark EV will be the first vehicle on the market to offer as an available option the recently approved SAE combo charger for DC Fast Charging. The capability, available shortly after launch, will enable the Spark EV to recharge up to 80% of its capacity in approximately 20 minutes. The battery system is capable of handling multiple DC Fast Charges daily. Charging can also be completed in less than seven hours using a dedicated 240V charge. A 120V charge cord set comes standard. Charging can be managed and monitored remotely using the Spark EV’s smart phone application, provided by OnStar, which is standard for three years.
The GM designed oil-cooled, permanent magnet motor is the heart of the Spark EV’s propulsion system. Putting more than half a million road miles on development versions of the Spark EV enabled engineers to make the performance of the electric motor the best it could be by using a bar wound copper stator and unique rotor configuration.
