Lotus Engineering receives the Award for the Evora 414E Range Extender Hybrid 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. 0-60 mph / 97 km/h in around 4 seconds Total hybrid range of over 300 miles / 483 kilometres Eco mode or Sports mode featuring realistic 7 speed paddle shift with energy recuperation Next generation of Lotus and HARMAN intelligent pedestrian warning system, integrating the advanced HALOsonic sound synthesis system with video technology. Torque vectoring for improved dynamic stability 152 kW (207 PS/204 hp) of power and 400 Nm (295 lbft) of torque

Ahead of schedule, Lotus' new Evora 414E Range Extender Hybrid Electric Vehicle (REEV) has started its dynamic and durability testing at the Lotus HQ in Hethel, Norfolk. Ÿ 1000 Nm (738 lbft) of Torque Ÿ 414 PS (408 hp) Ÿ 0-60 mph / 97 km/h in around 4 seconds Ÿ Top speed 130 mph (209 km/h) Ÿ Target emissions of just 55 g CO2 / km (NEDC) Brimming with innovation, technology, performance and power, 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 55 g of CO2 / km emissions on the Northern European Driving Cycle (NEDC). 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. It's all Torque Now that the car is undergoing testing, what does 1000 Nm in an Evora feel like? 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, "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!"
