Having said that, who better than Lotus to create a viable driver's machine with such an apparent disadvantage? For thoroughness, attention to detail and engineering alchemy, there's surely few better. With such an increase in mass, it was vitally important for Lotus to keep as much of it between the axles as possible. To that end, the battery pack sits where the rear seats would in an Evora 2+2 and the 1.2-litre engine sits comfortably ahead of the rear wheels. This has resulted in a weight distribution of 37:63 front to rear, which compares favourably to the 38:62 of an Evora S.
How does this translate out on the track? Impressively, in a word. As the 414E is currently a one-off prototype and we were only given four laps of a track there wasn't quite the opportunity to go in hard like Mr Harris did with the Exige S earlier in the year. Lack of familiarity with 'new' Hethel's layout didn't help either.
Down the straights though... In EV mode, which gives a range of 30 miles, the performance is not as strangled as you might expect. Crucially also, the accelerator pedal is fantastically weighted, meaning you can add more electric performance easily without causing the range extender and generator to chime in.
When you do ask the 414E for everything though, it responds instantly and ferociously. There is seemingly no delay between applying full throttle and deploying 414hp and 738lb ft to the tarmac, despite the fact that the range extender must start up and power the generator before the power is there. The surge, as you would expect, is hugely linear and apparently limitless, the Evora rushing though 100mph almost disdainfully.
But, because of this seamless nature, the performance isn't that engaging. The three-cylinder engine is a bespoke range-extender, so it spins only between 1,500 and 3,500rpm. Whilst this is the optimum engine speed to power the generator, it means there is nothing by way of crescendo as you accelerate, as there would be in a conventional car. Moreover, the noise emitted isn't particularly emotive currently, a rather industrial drone overlaid with a little three-cylinder hum.
The rest of the driving experience feels as well calibrated as we expect of any Lotus, with plenty of poise and feedback through the wheel. Moreover, whilst the suspension is stiffened to cope with the extra weight, it is still tolerable around the track's bumpy entry roads. And whether you are lifting off at 100mph or 30, the regenerative braking gives the same response, noticeably aiding the braking process but with such nuanced precision to be easily adapted to after just a few minutes.
The 414E shows that a range-extender hybrid drivetrain is a viable option for performance cars. With the REEVolution (get it?) still nascent, Lotus is promising (and will surely deliver) further advances in terms of noise with its HALOsonic technology and a simulated paddleshift also. PH will be outlining this and all the other tech that comprises the 414E package soon, so watch this space.
Finally, it is worth noting the Evora 414E is not intended as production concept; the car is a showcase for the technology developed as part of the tie-up, to display to the world that Lotus can develop hybrid powertrains. Now it hopes to outsource these skills, to profit from what they've learnt by installing the tech into the products of other manufacturers.
The 414E is far more than the sum of its statistics then. It shows Lotus is again at the vanguard of automotive innovation, delivering tangible advances before the competition. Interest in this project will only increase as it develops, which can only benefit Lotus further. No doubt it needs some good fortune right now, and the Evora Range Extender Electric Vehicle deserves to return Lotus to prominence.
