GRILLED Lotus Track Tests Evora 414ELotus Cars – that other Brit sports car maker – has announced the commencement of track testing on it’s Evora 414E Range Extended Hybrid Electric Concept. Testing is taking place at the company’s RAF Hethel track in Norfolk.

Lotus says it’s devoloping the 414E Hybrid to showcase the company’s new developments in plug-in, range-extended electric propulsion, new electronic technologies to enhance driver involvement. We reckon just wow would have been a sufficient reason. Anyone who’s driven the Karts that Lotus turns out will recognise the potential for superfast, extra-sporty electric hybrid racing.

From the outside it looks like Lotus has been evolving, lightening and tightening vehicles since the Elise specifically for this latest batch of low to the ground, corner loving karts. In 414E, Lotus Engineering has developed a highly efficient, high performance drivetrain system consisting of twin motors each limited providing 155 kW of power and 500 Nm of torque to each wheel ::::

Gone is the supercharged 3.5Lt Toyota V6 of Project Eagle – Evora – Replaced by a range-extender 1.2 litre, in-line 3 cylinder petrol motor and a couple of wizbang electric units. The range-extender drives an electric generator to keep charge up, it’s also capable of driving the traction/electric units directly.

When more power is asked for, the range-extender and battery storage combine for the best possible performance, acceleration.

Lotus is collaborating on the 414E project with the UK’s Vehicle Intergrated Delivery Program – VIDP –  REEVolution, a Government funded R&D group that includes Jaguar Land Rover, Lotus, Nissan and three UK technology firms.

Their eventual aim is to build a supply base in the UK for plug-in and electric hybrid vehicles. The funding for REEVolution was awarded as part of Stage 4 of the Technology Strategy Boards Low Carbon Vehicle program.

Lotus Track Tests Evora 414E Cut-out414E also made an appearance over the weekend at the Goodwood Festival of Speed, in the form of a cut-out as well as the running prototype. Lotus says its car will reach 100 kmh/60 mph in about four seconds before reaching a 210 kmh/130 mph top speed. “The acceleration sensation is almost indescribable, the surge of torque is like an ocean wave,” Lotus Engineering principal development engineer Simon Corbett said in a statement.

Kitted with an Xtrac independent – single speed – reduction transmissions, integrated into a single housing. The Xtrac system enables torque vectoring dynamic control of the vehicle  – capacity to generate different torques at each of the driving wheels – this is particularly suited to electric vehicles and significantly reduces the conflict between stability and response.

414E is due for production in late 2013, the exact specs for the production vehicle are still unknown. We could speculate – like every other motoring journo – or just put up the Lotus supplied pix and let you imagination stretch out over this low slung beauty…

SIMULATED PADDLE SHIFT

The Evora 414E Hybrid provides less of a psychological step change for people familiar with high performance cars compared to other electric and hybrid sports cars. The car has a simulated paddle shift gear change offering ultra quick gear changes reminiscent of a dual clutch transmission.

LOTUS DESIGN

The distinctive colour scheme and ‘floating’ roof have been carefully designed to accentuate the cars electric vehicle technology whilst complementing the iconic lines of the Evora. Copper, a colour often associated with electrical systems, has been chosen for the car’s exterior and interior. A contemporary satin finish paint is complemented by electrical circuit inspired graphics that highlight the car’s key feature lines and the unique glazed roof panel. Read more at Lotuscars.com

ENERGY STORAGE SYSTEM


The vehicle energy storage system is made up of the latest Lithium Polymer battery chemistry providing 17 kWH energy storage capacity. The battery pack is optimised for energy density, efficiency and high power demand, with over 300 kW discharge capability. For everyday commuting journeys, up to 35 miles can be travelled using battery power. The battery can be charged overnight using a conventional domestic mains supply through a socket concealed by the rear number plate. This permits the vehicle to operate with zero tailpipe emissions. For longer journeys, exceeding the battery capacity, the highly efficient Lotus Range Extender engine is used as a generator to supply the motor with electrical power and top up the battery.
