Lotus are currently showing their range-extender hybrid version of the Evora, the 414e, at the SAE World Congress show in Detroit and have picked the AEI SAE 2013 Tech Award.
Although not currently destined for production the Evora 414E Hybrid concept is used as a test bed and showcase for a wide range of Lotus Engineering developed technologies.
The Lotus Evora 414E Range Extender Hybrid was chosen by the Editors of the SAE’s Automotive Engineering International Magazine, for its design and engineering innovation, uniqueness, potential for “real-world” production application, and potential benefit for industry customers and end user.
Kevin Jost, Editorial Director of Automotive Engineering International Magazine said, “The Lotus Evora 414E was chosen for the AEI Tech Award for its unique combination of a multimode virtual seven-speed shift schemel, torque-vectoring stability control, and energy and power management optimization schemes.”
Aslam Farikullah, Chief Operating Officer for Lotus said, “In one high tech vehicle, the Lotus Evora 414E encompasses all the key areas of Lotus Engineering’s expertise, and doesn’t just demonstrate the high level of technological advancements in our products, but is also relevant to the motor industry and applicable to the long term future of the car. We are delighted that the SAE have recognised this with such an important and prestigious award.”
Every year, the editors of Automotive Engineering International select, from among SAE World Congress exhibitors, the technologies they judge worthy of an AEI SAE 2013 Tech Award. Judging is based on level of design and engineering innovation, uniqueness, potential for “real world” production application, and potential benefit for industry customers and end user. The SAE 2013 World Congress will be held this year from April 16 to 18 in Detroit; and other highlights of the event are viewable online at www.sae.org/mags/aei/saewc.
The Lotus Evora 414E Hybrid concept showcases new developments in plug-in, range-extended electric propulsion, new electronic technologies to enhance driver involvement and the adaptability of the Lotus Versatile Vehicle Architecture (VVA).
The range extended electric drive of the Evora 414E Hybrid consists of two electric motors driving each of the rear wheels independently via single speed geartrain, integrated into one common transmission housing, thus enabling torque vectoring for stability control of the vehicle. Electrical power is stored in a lithium polymer battery pack which is optimised for energy density, efficiency and high power demand and mounted in the centre of the vehicle for stability and safety. Additional range is provided by the Lotus Range Extender engine, an optimised 1.2 litre, three- cylinder engine, designed specifically for series hybrid vehicles. The drivetrain is designed to combine astonishing performance with efficient, low emissions driving.
Driver involvement is enhanced by the incorporation of HALOsonic Internal and External Electronic Sound Synthesis technologies from Lotus and HARMAN, which provide sound contouring within the cabin and improve pedestrian safety outside the vehicle. Integrated with the HALOsonic technology, the Evora 414E Hybrid also showcases a brand new technology from Lotus Engineering, a sports mode that simulates a 7-speed, paddle shift transmission that combines exceptional driver involvement for a hybrid sports car and optimised energy recuperation.
The Evora 414E Hybrid has been designed to highlight Lotus’ innovative electric and hybrid vehicle technology without distracting from the pure sportscar character of the Evora.
