Infiniti's Emerg-E range-extended supercar has been seen at so many events now it's hard to believe that it's only now making its first appearance in North America.

On display at the 62nd annual Pebble Beach Concours d'Elegance, a celebration of all things automotive, Infiniti will be hoping the car makes as big a splash as it did on launch at the Geneva show, and at the Goodwood Festival of Speed.

Though they might also be hoping it doesn't break down, as it did at the Festival...

Infiniti describes it as the first mid-ship electric motor powered sports car, and under the skin sits a plug-in, range-extended electric drivetrain developed by British sports car makers Lotus, from the Evora 414E platform.

That means twin electric motors developing a combined 402 horsepower, and a 0-60mph time of only 4 seconds.

It could do up to 30 miles on electric power alone, before a specially-developed 1.2-liter, 3-cylinder engine kicks in to add another 270 miles to the car's range.

While the concept is being endlessly toured, we're rather hoping Infiniti is working away behind the scenes to put the car into production--or will the Emerg-E be a car over which we're soon shouting, "just build it already!", like so many others?...
