Interesting, as you say they are in a great position to do this.

One option would be to keep with the 3.5L V6 from Toyota, this is used in the Lexus hybrids. In the Lexus app it only has about 1mile range all electric - the idea is to give the performance of a 4.5L V8 from a 3.5 V6 without adding lots of weight. Having driven a few it works well. This would seem to suit the Evora application if there is space for the battery / motor. Another 100BHP would be nice! This would give more power but not a huge gain in economy.

The other option would be more like the Tesla where the battery is charged via the mains and a decent range on battery (>100miles?). Having a small (1L?) petrol engine to both boost peak power and as a backup to recharge. This would make a lot of sense as a car - Tesla like acceleration (0 to 60 in 4 seconds), Lotus like handling and practical as you dont end up stranded if the batteries go flat.

Yes, excellent points. I didn't realize emissions were also a factor and assumed the Toyota engine won't be a problem. Hmmm. Perhaps the Evora S may be a high performance hybrid. :D

LOL Are Lotus marketing actually looking at this forum !

With the petrol engine, the larger weight of the tesla batteries wouldnt be needed. Perhaps clarksons ctiticisms of the teslas handling would be answered. So what about the screaming 1800cc 4 pot vvt engine from the 111r supported by a motor the size of a tesla and a third of the batteries.

For evora s read evora e

Tesla weight 1235 kg - 111r weight 860kg = 375kg

So 375kb is weight of batteries and motor. Say 50kg for motor. Batteries 325kg

Lotus keeps 125kg of batteries.

Electrics total to go into evora 175kg

cant find the data for the reduction in weight from the V6 vvti to the 1800cc vvti engine

Tesla motor 248 bhp + 1800cc vvt engine 189 bhp

Tesla motor 270 lb ft + 1800cc vvt engine 133 lb ft

(new Toyota 1.33 dual vvti engine will be produced in Deeside, North Wales this year. Say Lotus could tune to 150 bhp then maybe this would be the one)

Help. Can some bright spark further the calcs :-)

As I read the blog, it sounds more like a Volt configuration than a Hybrid. That is to say that the engine is used to charge the batteries alone and is not directly connected to the drive train the way a Hybrid is. All in all, it still sounds like a lighter configuration that strictly batteries for the longer range.

Could you expand on the volt configuration? Lighter than a Tesla? What type/weight of engine, electric motor and batteries would be needed as an example?

I think this is a take on the 'Volt' system.

What if the EV is going to be the new Esprit and not the Evora? What if the 'concept' vehicle is going to be released soon with the real deal going into the Esprit? That opens up some interesting possible configurations. It does sound like it will be happening a lot sooner that that, but just a thought...

More Power equals more speed down the straights. (The 'Lotus' Tesla blew the 'Lotus' Lotus away down the straights. Its only problem was its weight in the corners... TG )

Less weight equals less time round the circuit.

O my god. Could the Evora get the jump on the Cayman.

Lotus could cream off the demand at
