This is a very cool video from Audi that has engineer Moritz Reiff talking about the intricacies of the e-tron's e-quattro system.

This is great and all but I would love to see the potential for an S version of the e-Tron SUV or some other e-Tron model in a high performance trim.

I'd love to see that as well. I'm really curious about how companies like Audi will made sportier versions of the EVs without going straight to building a supercar.

Here's another video from Audi that gives a detailed overview of the e-tron.

The winter driving bits of that video are interesting to me. In a few months i'll have to prepare for winter and the e-Tron's improved control could better complement the tires I get.

Same here, I'm going to have to go on a test drive in the winter to see how it performs.

I had a Toyota Prado Kakadu with electronic traction control. At it's most simplistic it operated as follows: When a braked wheel was about to stop rotating, the brake was released. When a driven wheel was about to lose traction and spin, the brake was applied. And the three differentials allowed for full slip so that all torque could theoretically be directed to a single wheel with traction if that's all you had. This system worked brilliantly except in one condition: where ALL wheels were slipping/locking, you got a much worse outcome than you could have achieved without the system. Good tests for the ALB were on wet long-blade grass - the system could not find a braking pattern that resulted in any speed retardation. And in soft sand the system would end up braking all four wheels to ensure you could not go anywhere! They later developed manual override to avoid the bad outcomes but you had to tell the system that you were in that context - it could not self-detect the conditions as I believe the Audi e-Quattro system can. The e-Quattro system has the advantage of not needing a centre differential so it can be even more mechanically efficient compared to the complex Prado transmission including low range.
