Lotus Engineering will exhibit a hybrid concept model at the
Geneva Motor Show next week. The Evora 414E Hybrid is touted as a high-performance technology demonstrator with a plug-in hybrid series drive hybrid system and new technologies for driver involvement.
It's named 414E as it produces 414PS (408bhp) by using two electric motors driving the rear wheels. Reaching 60mph in less than four seconds the 414E has a claimed range of 300 miles thanks to the inclusion of a 1.2-litre three-cylinder range-extender engine. On a single charge (via a mains socket) the 414E can travel 35 miles on battery power before the range-extender engine is required to generate electricity.
To ensure Lotus's typically high levels of driver appeal the company has included a number of technologies in the 414E. Torque vectoring, which provides different torque levels to the individual driving wheels, aids agility, while a simulated seven-speed paddle-shift transmission also features. The virtual gearshift is used in conjunction with a simulated engine sound, while the drive torque is also modulated to give the feel of a gearshift jolt.
The replicated engine sound is played though the car's audio system and externally to warn pedestrians, with the driver able to select from a choice of four sounds including V6 and V12 powerplants. It's not just the sound that enhances the driving experience, as the simulated transmission allows the driver to enjoy engine braking - effectively giving the driver the choice of the level of regeneration from the drivetrain.
This Evora Hybrid is unlikely to make production as it is, but the concept demonstrates technologies which may feature on Lotus's models in the near future. Here's hoping.
