This year’s Green Car Vision finals are going to spice up with the finalists being Tesla’s Model S, BMW i3, Cadillac ELR, Mercedes-Benz B-Class F-Cell and Ford C-MAX. Tesla’s advanced electric power-train delivers exhilarating performance and as a result, Model S acceleration is instantaneous, like flipping a switch. In 5.6 seconds, Model S travels 60 miles per hour, without hesitation and without a drop of gasoline.
The i3 will be powered by a newly developed power-train consisting of a 134 horsepower electric motor running on lithium-ion batteries and driving the rear axle. BMW is aiming to achieve a 100 miles (160 km) range, the same expected for the BMW ActiveE, but in order to reduce weight with a battery capacity of 16 kWh instead of the ActiveE’s 30 kWh.
The Cadillac ELR is a future plug-in hybrid sports car developed by General Motors. Incorporating the propulsion system from the Chevrolet Volt—the battery pack, the 120-kilowatt electric motor, and the four-cylinder engine-generator, collectively dubbed the “Voltec” electric propulsion system—the Converj concept has an all-electric range of 40 miles (64 km) and a top speed of 100 mph (160 km/h).
The Mercedes B Class F-Cell is powered by a 100-kilowatt (136-hp) electric motor that produces about 214 lb-ft of torque pretty much all the time. This latest fuel cell is 40 percent smaller than the version in Mercedes-Benz’s previous test bed, the A-Class F-Cell, yet it produces 30 percent more power while consuming 30 percent less fuel. C-MAX Hybrid is projected to deliver class-leading fuel economy and beat the Toyota Prius v in both city and highway equivalent miles per gallon.
Though the technical know-how isn’t out yet, the Ford C-MAX line hits impressive fuel efficiency and range figures without sacrificing driving performance. Looking at the winners of past years such as Chevy Volt, Nissan Leaf, Ford Focus Electric etc. it is obvious that each year the competition gets bigger and better.
Who is your winner?
