The Infiniti EMERG-E concept that broke cover in Geneva is now a reality. The fully functional car made its debut at last weekend’s Goodwood Festival of Speed.

It is not a full production car as yet, and no word on when or if it will ever be made. What we see here is the demonstrator car, but it remains close to the concept in terms of power and performance. The twin electric motors generates 402 hp, achieves 0-60 mph (97 km/h) in just four seconds, and 0-130mph (209 km/h) in 30 seconds.

The motors empower the wheels via a single-speed (XTRAC) transmission. A quartet of inverters controls the motors and energy regeneration under braking. The recuperated energy will be stored in lithium-ion battery, which are mounted behind the seats. The battery is also rechargeable from a mains power supply and it is enough for 30 urban miles.

The EMERG-E can operate solely on electricity over a 30 mile (48 km) range. If needed, the range extender Lotus three-cylinder petrol engine will be called upon. It operates between crank speeds of 1,500 – 4,000 rpm; peak power is achieved at only 3,500 rpm. The tiny engine emits only 55 g/km of CO2 over a 300 mile (482 km) range.
