ummm, you raise f1, you said no race cars lose traction as a result of excess power - clearly you havnt read the f1 rules that clearly ban awd, clearly you havn't watched an f1 race in the last two years and seen the hybrid cars loosing traction (you mention you have tracked all races and never seen a 2wd lose traction at speeds in excess of 200kmh due to two much power (in some cases spectacularly), and clearly you havn't driven a tesla D car alongside a non D.
Also, one doesn't coast around a corner in any tesla, you drive around, in gear, on throttle, the entire way. You slow any tesla with regen, not brakes. Hence your neutral analogy is not relevant. Also you might care to note that the 85D has a smaller motor at the rear, making it and the 70D the only tesla that has the much covetted perfect weight balance. The 85 has a heavier rear motor, and the p85d heavier again. You are a mug if you think you coast around a corner off throttle in a tesla. Its not how they work, any of them.
Further, I can assure you that too much throttle around a corner in an 85 will cause you to lose the rear. Hence you drive the corner slower. The D car on the other hand, feel free to give it heaps with the right foot. The added traction allows far quicker cornering. The difference is very noticable. Take a test drive!
Again Paulp, you failed to read my comment properly.
I said I tracked cars and didn't lose traction as a result of excess power as is the correct method of driving cars around a dry tarmac track as quickly as possible. You feed the power on at the apex as the car stabilises out of the corner.
I did not say that F1 cars race cars don't lose traction. Nor did I say I have "tracked all races" (whatever that means), nor did I say I have never seen a 2WD lose traction. I've no idea where you came up with the figure of 200km\h.
I don't watch F1 but I do understand the physics and mechanics involved. They rely on special aerodynamic downforce onto the huge rear racing tyres for grip. Lightweight for speed and agility. AWD would not be practical as the weight disadvantage would not be made up for in traction. The same applies, to a lesser extent, to touring car racing.
Let me try and explain again:
A car is only two wheel drive or four wheel drive when drive power is actually going to those given wheels. When there is no power going to the wheels such as under braking, it is essentially zero wheel drive. The car is just rolling on four wheels.
Regardless of whether you are slowing down with regen, ICE overrun or disc brakes, when you are braking the car it is zero wheel drive. ICE overun or regen can play a part in the braking effort however it cannot shorten the best stopping distance as that is determined by the traction available (except during brake fade). So the fitement of AWD/4WD does cannot improve the shorted possible braking distances as AWD/4WDt is not in use under braking. The extra weight actually of AWD/4WD will actually increase braking distances.
Now, onto the corners. I'm completely perplexed at your driving method of going "
around, in gear, on throttle, the entire way.". You do not slow down for corners? At all? You go into corners with the throttle on the entire way around? (????)
OK THEN......
Moving onto a real situation, normal people will lift off the throttle on approach to a corner, apply brake, lift off the brake, turn into the corner (last two steps often blended together). Then AFTER having turned into the corner, feed the power on at about the apex point. Up until you feed the power on, which is about half way through the corner you do not press the throttle. Thus up until that point the car is again, essentially a zero wheel drive so AWD/4WD is not assisting in anyway except to add weight which again makes it harder for the car to turn the corner (simple physics).
You can coast around a corner in any car as long as you aren't going too fast. I've no idea why you think that is not possible.
Too much throttle on the
EXIT of a corner will often cause the rear the step out on a RWD car, so you are half correct there however the correct method is to feed the power on as the car stabilises from the corner. so when driving properly, even when going as fast as possible, the rear will not step out. This is where AWD usually has a advantage as you can typically feed the power on earlier and harder. But two wheel drive as I've already pointed out several times, has the advantage on the
braking,
entry and
apex of a corner. In those sections, as I've said over and over, AWD/4wd has absolutely no advantage at all and is actually at a disadvantage due to the extra weight.
You are obviously either a total idiot or an anti Tesla troll - please climb back into your cave.
Ray?
Honestly, all of thise is 100%:
- Tesla motors are mounted on the axle not underneath! I provided a image showing this. If you do not understand this, perhaps you should open the frunk of a D and compare the space to a non D. That loss of space above the axle in the D is due to?
- ICE 4WD systems are normally "balanced" by a centre diff which is mechanically locked with a 50% (or similar) split front/rear. No brakes are used (how could 4WDs get up sand dunes or cross rivers with the brakes coming on?)!
- I searched but cannot find any literature stating that dual motor Tesla's get upgraded brakes over single motor models. I asked politely for you to reference this claim.
I am not a anti Tesla troll. I have not said a single word against Tesla. I am a supporter. All I've done is point out incorrect information. I never thought I'd come on here and actually be dispelling myths about ICE cars (brakes for 4WD systems!) Very disappointing.
