It’s not often that a concept car gets transformed into a working demonstrator, but that’s exactly what Infiniti has done. The EMERG-E highly advanced mid-ship sports car that provides an exciting glimpse into Infiniti’s future is now even more exhilarating.
The demonstrator cars remain true to the spirit and inspiration of the original concept car with twin electric motors which generate 402bhp (300kW), making it capable of accelerating from 0-60 mph in just four seconds – and from zero to 130 mph in a 30 second burst. Crucially, it also operates as a zero emission urban transport over a 30-mile range and when the range-extender petrol engine functions in concert with its twin electric motors, it produces a CO2 output of only 55g/km (NEDC cycle) over a 300-mile range. These advanced motors direct their power via a single speed (XTRAC) transmission to create what is effectively an open differential, this arrangement significantly reduces driveline friction losses. The recovered power is directed to a lithium-ion battery mounted behind the seats. The battery can be recharged from a mains power supply (domestic and fast-charge) and stores sufficient energy to propel the INFINITI EMERG-E for 30 urban miles, at which point the on-board petrol engine starts up to act as a generator. This light, ultra-compact, Lotus Engineered three-cylinder 1.2-liter 35kW engine has been purpose-designed for its range-extending role. It operates between crank speeds of 1500-4000rpm, producing peak power at only 3500rpm.
See you in Goodwood.
