The Lotus Evora 414E Range-Extender Hybrid Electric Vehicle (REEV) has started its dynamic and durability testing at the Lotus HQ in Hethel, Norfolk.
The Evora 414E has 1000 Nm (738 lbft) of torque, 414 PS (408 hp) , a 0-60 mph time of around 4 seconds , a t op speed 130 mph , and t arget emissions of just 55 g/km CO 2 (NEDC).
The Lotus Evora 414E is a series hybrid technology demonstrator which shows some of the headline technologies that Lotus Engineering, one of the world’s leading automotive engineering consultancies, has within its portfolio.
The Evora 414E is powered by two electric motor packs driving the rear wheels through its Xtrac transmission with a battery pack that can be charged by the Lotus range-extender engine or directly from mains electricity.
The Lotus 3-cylinder range-extender engine has been design protected to run on either gasoline or renewable bio alcohol fuels (methanol and ethanol). It drives an EVO electric generator which produces electrical energy to either charge the battery pack or power the EVO traction motors directly. In normal driving, the Evora 414E will run purely on electricity stored in the battery pack for up to 30 miles (48 km). With the Lotus range-extender and the electric traction motors powering the vehicle through an Xtrac 1092 transmission, the Evora 414E is targeted to produce just 55g/km CO 2 emissions on the NEDC test.
Should the driver require more performance, under hard acceleration, for example, the electricity will come from both the battery storage and the small range-extender engine.
Simon Corbett, Principal Vehicle Dynamics Test and Development Engineer at Lotus Engineering, has been doing the majority of the development testing, over the last few weeks. He says that “The Evora S has 400 Nm of torque which, in such a lightweight car, is already a healthy figure. But the Evora 414E has two and a half times that amount! The acceleration sensation is almost indescribable, the surge of torque is like an ocean wave!”
As part of the REEVolution consortium, funded by the government’s innovation agency, the Technology Strategy Board, Lotus showed a cutaway version of the Evora 414E, with regenerative braking, HALOsonic and realistic 7-speed paddle shift technologies at the Goodwood Festival of Speed .
Evolution of REEV Technologies Building a UK Supply Base is a collaborative R&D project funded by the Technology Strategy Board that is creating new high performance Range Extended Electric Vehicles (REEV) and Plug-in Hybrid Electric Vehicles (PHEV). Three new demonstrator vehicles will showcase innovative new technologies. The cars combine and build on the skills of all of the businesses involved. The driving force behind this is to build a UK supply chain for new ultra low carbon vehicle technologies and position suppliers so that they can exploit the global market. The REEVolution consortium, led by Jaguar Land Rover, consists of: Axeon Technologies Ltd, EVO Electric Ltd and Xtrac Limited; and three vehicle manufacturers: Jaguar Land Rover, Lotus and Nissan Motor Company Ltd. for INFINITI brand .
