Infiniti Emerg-E

Infiniti Emerg-E Concept

 
The Infiniti Emerg-E is a two-place hybrid gasoline-electric concept that made its world debut at the 2012 Geneva Motor Show. While its sleek shape and stunning styling dropped jaws, those on the green side of things immediately recognized it as a reskinned and updated Lotus 414E – itself a concept based on the Evora that debuted at the same show only two years earlier. Yet there is little wrong with a reworked, Infiniti-badged Lotus boasting 402 horsepower and 738 pound-feet of torque, especially when it features a lightweight, all-aluminum bonded chassis beneath an attractive carbon fiber skin penned by the automaker's Southern California design team.

The hybrid powertrain is all contained aft of the cockpit. Primary propulsion is accomplished with two electric motors, one on each rear wheel, both featuring its own single-speed transmission (this design eliminates the need for a differential and provides electronic torque vectoring control). Energy for the electric motors is stored in a 15-kWh lithium-ion battery placed behind the seats, which is chemically different from the lithium-polymer pack Lotus used in its 414E. Auxiliary propulsion comes from a Lotus-designed, all-aluminum, 1.2-liter three-cylinder gasoline engine, rated at 50 horsepower, that serves as a range-extender after the 30-mile life of the battery pack is extinguished. Teamed with an 8.1-gallon fuel tank, the combo allows the Emerg-E to cruise about 300 miles without stopping. Offered the chance to take the Emerg-E for a quick loop around an autocross course in Southern California, I jumped at the opportunity.
