Ok. Yes I wonder if they have to charge them between runs? In this video the Tesla does multiple street races and I am guessing he did not charge between runs.I meant more road course than drag. Drag is where they shine as they're done by the time heat starts building up.
This. You want go fast, or put on a loud show? I always cared more about speed and don't care if anyone sees it, knows about it, or cares. I appreciate the sound of my of my '03 Cobra. But at the same time, all that sound? Is energy not making the wheels go faster. I also hate, from an engineering perspective, how much energy is thrown overboard via the radiator. Gotta have it, won't run for long without it. But it's all energy from your gasoline that is, in the most literal sense, NOT making you go any faster. Airplanes can get around it with careful ducting of the exhaust and radiator cooling exit air to reclaim some forward push from what is otherwise thrown away. But not cars.That makes no sense. Why are you thinking about dildos and gimp masks? Are there things we should know about?
I am just curious if this would be feasible and if it would improve performance. We all know RWD ICE cars suck from a dig unless you are on the right tires and heat them up and you know how to launch. Meanwhile a Tesla beats the crap out of most RWD and even AWD ICE cars from a dig.
So what if the rear wheels are powered by ICE and the front wheels by electric motors. Wouldn't that help as far as performance goes? You still get the engine / exhaust noises of the ICE and another boost from in wheel electric motors at the front? Perhaps there is not benefit and this is not feasible at all? That is what I am curious about.
I want both lol! Go fast and loud! ICE is a lot more inefficient than electric. But it sounds 10x better.This. You want go fast, or put on a loud show?

Wanna go fast? Or put on a show? That's your choice.
For full disclosure: I've always been into electric RC cars. I've never had any trouble outrunning the guys running gas. It's why they have separate classes for gas and electric.
Thanks for the reply. Hopefully something mainstream will appear on the market. These Tesla's are humiliating muscle cars left and right. Dodge, Ford and GM are still stuck with their RWD mindset and it just does not work out well against AWD electric. I would like to see a hybrid gas / electric AWD that can launch better in less than ideal conditions.I contacted those companies almost 2 years ago for exactly the same thing you are thinking.

I also a looked at this chinese stuff, but not sure on reliability for the price and Max RPM
for wheel seemed to low, once you get over 110 MPH (27"ish dia tire). At least it has a disk for brakes though and bolt pattern can be picked to match up with rear already. I'm not sure if max RPM applies to active motor, or just motor bits along for the ride (bearing speeds maybe) .

My idea was a very small batt pack in the spare spot, and only use the motors from a dig through 30,
maybe 40 MPH (I don't have traction issues ever after that). That way I figured the motors could be much smaller.
I was not that concerned with handling, how much worse could it be than 6-800 lb heavier hellcats (even if
extra unsprung weight) and no one seams to be regularly putting them down for a primarily stoplight drag rig.
No one in the US that I could find seems to be working on it.

Dear James,
Thank you for your message and enquiry.
We are still mostly focused on production oriented projects with the industry and that keeps us really busy, but we still planed to supply to individuals later, once we fully commercialize the technology and enter economies of scale. However, if the project is really something special, we are interested to work on such project if the team, the funding scheme and timeline fit to the expectaions on both sides.
If you are interested, please also check out the video of winter testing of two vehicles (SUV and a SEDAN) with our in-wheel motors:
Kind regards,

Electric at front wheels and gasoline for rear wheels. Traction is the issue affecting RWD cars. Good drivers and ideal track prep / tires overcome that but it would be nice to start beating Tesla's on any street. Not sure how easy it would be with a hybrid setup though. Tesla clearly did their homework when it comes to 1/4 mile performance. Really looking forward to see what the Tesla Roadster with the Space X runs.I think a plug in hybrid RWD might be an interesting sports car compromise, as long as it's done with enthusiasts in mind. Take the mustang, keep the 5.0 (or 5.2, 6.8, etc) and stick a 75ft-lb electric motor between the ICE and the 6M. Perhaps incorporate it into the 6M. Throw in enough batteries for ~40 miles of Power Wheels mode.
Stop and go and commute cruising can be done on electric, while plenty of power and range for having fun, all routed through the 6M to give the driving fan a great experience.

Yep I read about that. The other issue is the wheel motors would be exposed to road debris, water, salt etc. Not so much an issue if the car is only driven in nice weather and on good roads.Also: electric motors in the wheels is a terrible idea from an unsprung weight perspective. And it gives the motor a beating it doesn’t need.
Transmissions, differentials and axles have been elevated to high degree of refinement. Use them, and keep the motor in the body of the vehicle, where it belongs. With variable frequency speed controls, you can even toss the transmission, for ordinary passenger cars.

And how many micd-class cars has McClaren been content to race? Not a single one, I'd bet. As for having active torque control? You'd still be better off with four motors, mounted inboard, with direct drive CV axles to each wheel. Now you've got the best of both. There is no way those guys do not know this.Yep I read about that. The other issue is the wheel motors would be exposed to road debris, water, salt etc. Not so much an issue if the car is only driven in nice weather and on good roads.
But if handling is compromised too much it would not be worth it. Time will tell. I have a feeling something will be developed in a few years to give existing ICE FWD / RWD performance cars better launching capabilities to compete with electric cars.
Heresy Unsprung, Lotus Engineering: Unsprung Weight Doesn't Really Matter Much - The Truth About Cars
Here’s what Steve Williams of Lotus Engineering said:
Whilst it is true to say that the vehicle dynamic performance was degraded by the increase in unsprung mass, the degree to which this was noticeable was small and could be said to have moved the overall dynamic performance of the test vehicle from class leading to mid class. Further more, the understanding gained from this study has led Lotus to believe that the small performance deficit could be largely recovered through design changes to suspension compliance bushings, top mounts, PAS characteristics and damping, all part of a typical new vehicle tuning program.
Add the powerful benefits of active torque control and Lotus’s finding make a strong argument for the vehicle dynamics benefits of hub motors as an EV drivetrain.
