Two years after the Infiniti Emerg-E debuted at the 2012 Geneva Auto Show, parent company Nissan's vice president finally confirmed that early production promises were premature. Instead of producing this plug-in prototype, the automaker will double down on its pursuit of all-electric technology. From telltale ambient lights that pulsate and snake through the cabin, to a silent hybrid drive system full of power, this prototype is a preview of Infiniti's electric possibilities.

Channeling its sporty predecessors

The Infiniti Emerg-E is the brainchild of designer Randy Rodriguez, who first burst onto the automotive scene as the creator of the Nissan 370Z. Rodriguez employed some of the same design elements in this new model — namely a sculpted silhouette, low center of gravity, and carbon fiber body. However, Nissan isn't the only automaker that's recognizable in this electric prototype. As soon as the Emerg-E concept car debuted, critics were quick to compare it to the Lotus Evora and its electric offshoot, the 414E.

The British automaker's powerful, luxurious Evora isn't quite as lightweight or eco-friendly as the Emerg-E, but the cars' common features include two electric motors, vented brakes, forged aluminum suspension control arms, and a chassis made up of bonded aluminum sections. Even the torque is comparable; Infiniti claims the Emerg-E will go from zero to 60 miles per hour in just 4.1 seconds, even better than the Lotus Evora's 4.9 seconds.

Introducing a greener engine

Of course, the prototype’s most notable advantage over its upscale inspiration is the battery. Instead of equipping its engine with a lithium-polymer battery like the Lotus 414E concept, Infiniti gave the Emerg-E a lithium-ion battery with phosphate chemistry. This particular breed of battery can withstand frequent charging better than some alternatives (including the Nissan Leaf's manganese-based option), and Infiniti claims it will fully charge in six hours at a 240-volt power source.

The plug-in electric engine is also equipped with a range extender, which makes life easier for drivers who want to drive more than 30 miles on a single charge. After the battery dies, the extender kicks in to power a small generator that can yield up to 35 kW, achieving highway speeds of up to 90 MPH. However, this extender adds another 190 pounds to the Emerg-E's 450-pound core, weakening some of its aerodynamic capabilities ever so slightly.

You probably won't see the Infiniti Emerg-E in dealerships any time soon, but if you're curious about the future of all-electric sports cars, this award-winning prototype is full of new technologies worth watching. In fact, Infiniti is likely to follow the Emerg-E with a luxury sports car that charges wirelessly and achieves even better range.
