Infiniti EMERGE-E demo car emerges at Goodwood

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.

    Front spindle design again? Have the Japs really run out of design ideas?

      It’s no secret that this is Evora-based, and shares alot of things with the Evora 414E. Our last paragraph has this phrase “the range extender Lotus three-cylinder petrol engine”.

      Here are extracts from Infiniti’s press release:

      The desire to stretch Infiniti’s knowledge of electric vehicles lead to the idea of a range-extender electric vehicle, and just such a machine began to be developed in Japan. An unexpected opportunity to advance the project through Britain’s Technology Strategy Board (TSB) – whose mission is to speed the passage of low carbon vehicles to UK roads – provided the chance to access new technologies and work with a variety of organizations. These included universities, suppliers and OEMs, this facet of the development broadening the scope and ambition of INFINITI EMERG-E. The opportunity to work in a consortium revealed that fellow member Lotus Engineering was also developing a range-extender electric sports car, the two companies deciding that it made sense to collaborate. That decision, explained Bancon, was eased by the fact that “Nissan (and Infiniti) have had a relationship with Lotus for 10 years, mostly about methodology. We have never agreed a contract to do a car with Lotus, but we have done many studies together, utilizing their additional resource when ours was taken,” he said. Further benefits included co-funding of the INFINITI EMERG-E project from the TSB, and access to a range of highly innovative suppliers.

      “Silence is the new vroom,” said Bancon of INFINITI EMERG-E’s potent and technologically advanced drivetrain. “It is elegantly silent, and responsible.” INFINITI EMERG-E is a range-extender electric vehicle, and it is propelled at all times by a pair of 201bhp (150kW) EVO ELECTRIC motors driving the rear wheels. These advanced motors direct their power via a single speed (XTRAC) transmission to create what is effectively an open differential, this arrangement significantly reducing driveline friction losses. A quartet of inverters controls the motors and their energy regeneration role under braking, the recovered power 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-liter35kW engine has been purpose-designed for its range-extending role. It operates between crank speeds of 1500-4000 rpm, producing peak power at only 3500 rpm.

    Why does this look like a Lexus LF-A knockoff? You know like how the Chinese can copy a Cayenne or BMW X-5 shamelessly. This one might as well be called the Lexus LF-XX

    So Lotus uses their engine, in turn they borrow design cues from Evora. I thought the Lexus design studio is bigger than the Lotus factory…

    Lexus’ spindle grill front marrried to Lotus Evora lines. Oh wait!! It is Lotus Evora!

    It’s no secret that it is a Lotus Evora underneath. Nissan has gone to lotus for a few times previously, most famously to sort out the GT-R R35 handling during its development stages…
