usually mid cycle so are we going to see some tweaks for 18?

Anything earlier will be icing

I think they are predicting that GM will hit their 200Kth ev and thus the fed tax credit will taper down.

As for tweaks, if the g1 was any indication, the g2 mid cycle tweak will likely be a slightly bigger battery, maybe some software mods to make it act more like a CT6 PHEV to give you blended ice and EV performance in sport mode, and probably the loss of an existing color and the addition of a new color. I'm sure many are hoping for a homelink option plusman option for power seats, but I just don't think gm will do it. The wet dream prediction would be a volt wagon lifted 4 inches with a wider stance and AWD making it into a Crosstrek competitor... never gonna happen, but we can always hope.

I dont see AWD ever because it cannot be efficient. The wheels/motors will fight against each other creating resistance. If the wheels had individual motors, then we'd have to study it again and see what could and cannot be but until then, not likely.

??????????????????????

If they don't have individual motors, its' just like an ICE with AWD. The motor (EV or ICE/EV, depending on mode) drives the drivetrain, just like the current Volt.

With individual motors and the ability to instantly increase or eliminate drive at a wheel, your could run 2wd until a loss a traction, then kick in the other two wheels instantly. It would be MORE efficient than standard AWD, and off when not needed without any friction losses.
That would be cool actually, as you could run it in RWD for better dynamics and handling, and have instant AWD when needed.

It could be done like Toyota does their 4WD. Engine/motors power the wheels in the front, another motor powers the wheels in the back. Their hybrid 4WD-i system doesn't have much horsepower in the back, but you don't need a lot to get way better traction than FWD.

Unless you put in a clutch on each wheel so the electric motors can be disconnected from the wheel, this is a bad idea as the momentum carried into the electric motors when not powered would clobber your fuel economy. This is like trying to run with your shoes attached to concrete blocks or filling your tires with water instead of air.

e.

A 2017 volt gets 3 credits for GM, a 2018 model gets 2 credits.

A rather large financial incentive for GM (or any other manufacturer) to make 2017's as long as possible.

I don't expect many 2018 EVs to be released much before 2018 because of this law.

Isn't it about when the car is sold rather than what year model they say that the car is?

Tesla's AWD is more efficient than the RWD model with the same battery size...

Nope not at all, that credit is based on the model year being manufactured, don't even need to sell it for the credit.

Indeed. Tesla runs the front and rear motors with different gear ratios, so they can optimize which motor to emphasize. Unlike an ICE vehicle, there is no transfer case or second differential to introduce extra inefficiency.

Look at the Mitsubishi Outlander PHEV, if it ever makes it to the States, for an example of what a Voltec-like AWD vehicle could be.

Well, I learned something new today as I too would have thought just the opposite.
