Lotus Evora 414E Hybrid revealed; showcases technology, not production car
3 March 2010

The Lotus Evora 414E Hybrid concept, unveiled today at the Geneva motor show, is a technology showpiece rather than previewing a production car.

Based on the Lotus Evora platform, the 414E's standard drivetrain has been removed and replaced with a plug-in series hybrid drive system.

Power for the Evora 414E is provided by a pair of electric motors – one located at each rear-wheel – with a single-speed reduction transmission allowing torque vectoring between each unit. Each motor produces 204bhp or 207bhp, which explains the 414 name.

The concept’s lithium ion batteries can be charged via a typical household plug or the car’s onboard generator – a 47bhp 1.2-litre three-cylinder Lotus Range Extender petrol engine.

Lotus claims the car hits 0-60mph in less than 4.0sec.

Lotus says the Evora 414E can travel up to 35 miles on all-electric power.

Lotus is hoping to sell this technology, and is using the Geneva motor show to showcase it to clients.

Also aiming to sell the Evora's chassis architecture as did with VX220 so expect to see another sports car with this chassis.

To improve the driving sensation, the concept also includes a sport mode that simulates a seven-speed transmission at work.

This is activated via a flappy paddle system that makes the noise of a gear change, and puts a jolt through the motors if you 'downchange' while decelerating using engine braking.

It also features Lotus’ HALOsonic Internal and External Electronic Sound Synthesis, a system designed to improve pedestrian safety through an external sound system.

In addition to proving an audible warning to those outside the car, the system also simulates four engine sounds for the driver, including a V6, V12 and a futuristic propulsion sound.

A Lotus source also confirmed the company is aiming to sell the Evora's chassis architecture as it did with the VX220, so expect to see another sports car with this chassis.

Our Verdict

Lotus Evora

Lotus moves upmarket with a 2+2 GT, but is the Lotus Evora an everyday car?

Lotus adding needless weight with synthetic sound generators. a sad day.

I hope it will not be standard fitment. For safety purposes a sports tyre that happens to be noisey will suffice.

A hybrid from one of the greatest sports car makers of all time. Is nothing sacred?

Anyway, as I keep on saying, internal combustion-powered hybrids will soon be considered utterly irrelevant. Lighter, smaller, smoother, simpler, much more reliable microturbines will soon supersede them altogether. I don't want a bloody 3-cylinder thrumming away under the wail of a fake V12 in a Lotus, thanks. Even less do I want it in the new Jag XJ. Please, Jag, Lotus, Toyota, everybody, listen to me. Turbines are the way forward.

Well, if that isn't bovine excrement, I don't know what is. Gimmick, gimmick, gimmick, gimmick. Lotus, please scrap this ridiculous idea right now. Pull the concept. Anything to kill the whole thing off. It's not going to be a proper Lotus, it'll be way too heavy.

A nice system, the same as will be in the Proton concepts that were put on the website earlier. It will be interesting to see how heavy it is though given Lotus's position on lightness. But don't put the fake gears in. Linear delivery is an advantage of electric power. And forget the fake noises also. Tyre and wind noise play a large part in hearing a car coming, especially one that is not accelerating. Electric cars will be more consistent in the noise they output, surely that will be safer once people become aware that such cars are on the road, which will be a very quick process once there is a volume model on sale.

I still don't understand why automakers are turning to electric vehicles. As long as the production of electricity accounts for the majority of greenhouse gases, the whole notion of electric vehicles makes zero sense. Hydrogen and other alternative fuels would probably be a better option if the industry really cared about the environment. It certainly leaves me wondering if there is an ulterior motive behind electric propulsion.

Excuse me for my rambing as it really is frustrating to see even Lotus considering electric power - a sad day indeed.

25 February 2010

Like it or not, and I don't, I think that electric motors with a small internal generator charging the batterries will probably be a big part of the future.

25 February 2010

The Evora is not a particularly light car anyway. Lotus seems to be adding weight like other car makers.

This system, if it is not too heavy, seems a great idea. And the small engine to recharge the batteries answers, in part, those concerned about electricity generation.

I hate the idea of the artificial sounds. We need quieter vehicles on the road.

All aftermarket add-ons to make noisy exhausts should be banned, I don't care if it puts Halfords out of business!

Lotus seemed to have designed a near future sports car that will be exciting to own and drive. FAB!

25 February 2010

Interesting concept and exactly the kind of thing Lotus should be doing, but there are a few issues to overcome. The main one, is that such a car (indeed any hybrid), will have two distinct levels of performance available depending on the state of charge of the batteries. Lotus obviously quote data for the fully charged mode, however with only 47 bhp continuously available, a long distance cruising speed of no more than about 80mph can be expected. And the battery will quickly discharge if any of this car's prodigious performance is used. Lotus quote just 17 kWH energy storage capacity, the equivalent energy of about 2 litres of petrol. So don't expect to see this car wizzing around the Nurburgring any time soon, Snetterton might be a more realistic challenge. Yet despite this limitation, this might be a really excellent solution for the UK, where low average speeds are the norm, but where occasional strong bursts of acceleration are needed. I wonder if Lotus is brave enough to let a journalist drive it?

25 February 2010

Forget the arcade game noises, that for kids to play with. New technology should move the game on and deliver new experiences, not force it to replicate old technology.

This car would give the Tesla a real run for its money and should be whole lot cheaper.

My only question is the location of the motors. Autocar quotes this as at each wheel, but if they are within the hubs this will add a lot of sprung weight which will corrupt ride and handling, so Lotus need a clever solution to this as this is their USP.
