im sure many people think of it but i found russians just testing them allready for cheap, just DIY frame and put some ecsiting e engine on it ... boom its E off roader



just charge it on garage or other place and then drive it . no petrol needed.


i guess you still need to pay for that E bill in the end there.... but what if you put more solar panels there ...
 
I'm eagerly awaiting Protean/NAVS hub drive. They were going to be largely aftermarket. But now they're largely getting used in the EV SAAB's. They can make any car into an AWD car by adding 2 to the non-drive wheels. Or you can make them run all 4 wheels. If it were available now, I'd throw it on my Foz, and I'd love a RWD pickup truck with low range and throw the hub motor on the front. The amazing thing is that it actually reduces unsprung weight as the system is lighter than present brake systems.
*As of now, solar is pretty worthless to charge a car. Solar on the roof of your house, to charge when your car is plugged in is fine. But the roof of your car is far too small for useful charge. You'll be lucky to get 20km a day in the summer to charge a battery for a car.
 
@Kevin There's another hub drive that's actually available now for some cars. But you have to use their wheels for that hub. Useless if you want lots of rubber. But it would be fun for some cars

That's a game changer.
 
Yes those are interesting ideas why have there just brake pads if you could have some e motor there to help you drive and brake and it woulf generate you electricity.
But even better hybrid subaru would be good if they could make it mote powerfull wirh larger battery. More like range rovers have with small 2.0 engine and rest is on E . Save fuel a lot and saves those brake pads as now car brakes almost on e motors.
 
@scalman
I'd love a full electric powered hybrid. With the engine only being used for charging. We could finally jam +31" tires on our cars😂. No real worry about gearing
 
For a DIY electric off reader, what about the bloke from piranha off road" who crossed the simpson desert in a Suzuki sierra powered by an electric motor & using solar panels to keep it going.
Greensuby.
 
sure engine could be used for charging and when needed some extra power maybe even. but then depends how powerfull e motors would be that petrol engine could be very small and all system would be very eficient on petrol usage that way. you just need to have that extra petrol for when going remote off road and then in city just cruising around in silence.
but then totaly new software must be made for proper off road control of those motors, well tesla showed that it can do pretty good in those harder situations just it need more ground clearance. and then those new Jeep compass and renegade models PHEV as they call them 4xE with 1.3 engine in front for front drive and E motor in rear for rear driving, i wonder how well they combined those 2 for off road there.
 
It would simplify the drivetrain a lot more to not have the engine driving the wheels. It could also be built to charge and run at a specific RPM then shut off. Basically built with cams to run only at peak torque. Ideally keeping the batteries between 25-75% charge for longevity. The motor could be quite small if it's only designed to charge batteries and not drive the car.
This is likely Mazda's plan with the future rx9. The rotary may even be less than 0.6L
Possibly even using capacitors to hold excess charge that makes up for the battery's internal resistance. Then have the capacitors trickle the charge into the batteries while the motor waits for its next start
 
but for me at least more interesting as more and more they starting to converting existing cars to EV ones, some companies even seel like kits to make it yourself, other people buying some old cars and convert themselfs. i mean its ineteresting project , it must be , if you have your own land and maybe even forest near your house, you dont need to drive it to main roads even , just make yourself some electric off roader for weekend, doesnt even need to be legal to drive on roads.
 
Definitely, and I think that's really the future for people without a ton of money for getting EVs. It's also pretty simple to adapt them. I don't know about where you are, but in the US, most states are pretty hands off with allowing EV conversions.
*My 300zx was destined to become an EV but I got rid of it due to covid. I'm hoping to get another one in the future
 
@scalman ideally it would be a plug in. Where you only need gas for actual journeys. Having enough battery for all your day to day needs. Its all about battery management and picking the right capacity. With the new sodium batteries coming, it'll be easy to get away with a smaller bank because their capacity and resistance is so low. But even having the ability the new Toyota Sienna and Rav4 has would be outstanding. But I'd like to have a smaller engine and more battery capacity than what they're running.
