Tesla PV batteries have heaters, so I would assume their cars also have heaters.

Good point Doc, I’d missed that one. 
do these cars have like a dynamo within that charges as it drives? 
I noticed the recent advert for the Lexus says it charges as it goes now. Surly this would have been a first thought :C  

cant get more energy out than you put in... to connect a dynamo and get energy from it will require more battery power to drive the car forwards to start with...

yes I follow the logic, just curious as to how Lexus claim to do it?

regenerative braking. THe wheels are driven by electric motors, and as we all know a motor can also be used to generate, so when driving downhill or slowing down, they can be used to boost the battery, same as F1 cars.

Regeneration, a technology from the glorious days of trams. A tram going down hill feeds in to the system, a tram going up hill draws that power off the system.

I altered two DC traction drives, I got shouted at because I’d reduced the deceleration rate and the feed back rate. The amount of power returned to the system was the same but slower. It saved a fortune in mechanical repairs to the drive train.

I had wondered if the F1 technologies were filtering through.

I don’t think so .... F1 engines are far more efficient than people realise, but so complicated extremely few people could fix them

F1 tech does filter through, but obviously in a more basic form. Hybrid cars use regenrative braking, not sure if F1 did it first or not.
