The state of California has the highest number of green cars to be found in North America. That is exactly why Fiat and GM chose to unveil their first entirely electric production models, the Fiat 500E and the Chevrolet Spark EV, at the most recent Los Angeles Auto Show. There is no doubt that this type of vehicle is on a major rise in popularity everywhere, but the main marketing thrust for Chrysler (with Fiat as intermediary) and GM is to sell a car that will help Californians respect future state standards for zero emission vehicles. By 2025, 15.4 percent of vehicles sold in standards. If its spec sheet is to be believed, the Spark EV seems to be the most proficient of the two models. The electric motor developed by GM produces 130 horsepower (110 kW) and 400 pound-feet of torque. The 20 kWh lithium-ion battery can quickly recharge itself, thanks to the SAE combo DC fast-charging capability that enables the battery to reach 80 percent of its charge in 20 minutes. It is also possible to plug the vehicle into 240-volt and 120-volt conventional plugs. By using a 240-volt recharge post, a fully charged battery can last 7 hours. GM has confirmed that this car will have the longest autonomy of all electric city cars. For the Fiat 500E, Fiat has announced a battery autonomy distance of 80 miles. Recharge time is estimated at 4 hours on a 240-volt outlet. The electric motor can produce 111 horsepower. The transformation of the 500E required engineers to improve the aerodynamics of the body as well as interior soundproofing.
