Set to debut at the 80th International Geneva Motor Show, the Lotus Evora 414E concept is a hybrid plug-in technology demonstrator that uses a 1.2 liter, three-cylinder engine and independent electric motors for each of the rear wheels. The result is 0-60 mph (97 kph) in under 4 seconds and power output of 414 PS (306 kW). The claimed range of over 300 miles (483 km) and glass engine cover are also impressive, but one of the most interesting aspects of the car is its sound system. To address concerns about pedestrian safety raised by the arrival of near silent EVs and hybrids, Lotus has worked with Harman International to develop "HALOsonic", a "noise solution" that works externally to alert pedestrians and internally to give you the fun of real engine sounds.
The other half of the hybrid system is made up of the Lotus Range Extender engine - a 1.2 liter, three-cylinder engine designed specifically for series hybrid vehicles which will also feature in Proton's hybrid offering at Geneva.
Producing 35 kW (48 PS/47 hp) of power at 3,500 rpm, the engine can be operated on alcohol-based fuels and/or gasoline and delivers power to the battery pack via an integrated electrical generator.
A battery-only range of 35 miles can be achieved for everyday commuting and plug-in charging from mains supply is through a socket concealed by the rear number plate.
On the emissions front, Lotus has this to say: "With regard to the total lifetime CO2 emissions of the vehicle, including the energy required to manufacture and run it, the range extender solution has a lower overall CO2 footprint than a fully electric car of comparable performance and operating range running with a larger battery".
The body itself is based on the conventional Lotus Evora and features the same versatile low volume architecture that enables variation of width, length, height and strength.
