The Lotus Evora 414E Range Extender Hybrid was chosen for an AEI SAE 2013 Tech Award by the editors of the SAE’s Automotive Engineering International magazine.
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.
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. The SAE 2013 World Congress is currently being held in Detroit. Highlights of the event are viewable online.
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 a 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 optimized for energy density, efficiency and high-power demand and mounted in the center of the vehicle for stability and safety. Additional range is provided by the Lotus Range Extender engine, an optimized 1.2L, three-cylinder engine, designed specifically for series hybrid vehicles. The drivetrain is designed to combine performance with low-emissions driving.
HALOsonic Internal and External Electronic Sound Synthesis technologies from Lotus and HARMAN are designed to 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 seven-speed, paddle-shift transmission that combines driver involvement for a hybrid sports car and energy recuperation.
- 0–60 mph 4.4 seconds.
- Total hybrid range of more than 300 miles.
- Eco mode or Sports mode featuring realistic seven-speed paddle shift with energy recuperation.
- Next generation of Lotus and HARMAN intelligent pedestrian warning system, integrating the HALOsonic sound synthesis system with video technology.
- Torque vectoring for improved dynamic stability.
- 408 hp of power and 590 lb.-ft. of torque.
