I think this is Tesla's "secret weapon", but is it enough to make up for M5s much higher power/weight? What do you think? Will be very interesting to see how they compare.

I started a thread on another forum about battery replacement. I will not get into all the details here (boring) but my theory is that the per cell cost will stay stable while manufactures back fill with capacity. I concluded the cost of the battery will not fall. Another poster pointed out that fewer cells will provide the same capacity so price can fall. Made sense to me.
The point of the above is that Tesla has created a product where performance can INCREASE with age. Spit ball an 8% increase in capacity per year over four years. I'll use 35% as the four year componded number. Cells make up a good bit of the pack weight so let's use round numbers and say the pack drops by a little less than a third or 300lbs. Stomp on the gas when you have two 150 lb guests then punt them and do it again. There is a big difference. Dropping 300lbs of battery will increase straight line and cornering performance. I can not think of another car that has the potential to improve with age. NEAT.
Trends and potential are interesting, but the hear and now (in stock form) is most interesting, no?
To me, the M5 and S6 both felt like they had faster peak accleration. Frankly, the MSP's peak acceleration is underwhelming to me. I know I've seen the video clip where the M5 loses 2 out of 3 to the MSP. Did anyone else notice that the M5 was losing grip while the MSP was sticking? To my eyes, the M5 lost because it had too much power at low speed. None of the cars that I drove recently have slipped when I floored it going straight, so I'm not sure why the M5 did in that video.
When I first drove MSP, I couldn't believe how good its traction control was. It works well to accelerate about as quickly as it can given the conditions. Then I drove the M5 and S6, and I swear their traction control is better. I guess Audi has Quattro, but somehow the M5 can compete despite being RWD and having a gasoline engine. Even in the video where the M5 tires are slipping for the first couple seconds, it does a reasonable job keeping pace with the MSP whose tires are sticking.
As far as body roll goes on the cars, I didn't really feel it on any of the cars (I drove a Hyundai Genesis in my shopping, and this did have noticeable roll). MSP, M5, and S6 are all using air suspensions, right?
As far as shifting goes, I can't believe how fast M5 and S6 can shift. It's a fraction of a second, and it's got to be some 5 times faster than the Infiniti M56. And yet even at a few hundred milliseconds, the delay is there and it annoys me. When you stomp the "gas" pedal on the MSP, it just goes. I imagine that was a big part of why for me, the MSP was simply more fun to drive.
Because of that, I bought the MSP [or more specifically, agreed to buy one].
But if I wanted a car that would get me the best track times, I would think the M5 would be a better choice over the MSP.
I doubt chrisn is going to have to pay out on his dinner bet.
Incidentally, I occasionally continued to post on the AudiWorld forums after telling them that I chose the Tesla. Most were quite gracious. A few are mad at USA policy that has provided Tesla some advantages. On the whole, while I was choosing between cars, I would say TMC and AudiWorld treated me about equally. Each had a couple of vocal members that thought I was a complete idiot for considering something else, and a bunch of people that wanted to provide some equanimous input.

disclaimer...M5's and S6's are pretty sweet and if I wanted to buy gas (or if it was 10 years ago) I would definitely want one

The key metric is average torque delivered to the pavement across a range of speeds and times. MSP does very well despite having a much lower torque rating. The reason is, that the M5 spends relatively little time at its maximum torque value, while MSP is almost always at or near its maximum. If MSP is going to beat an M5 anywhere, it's going to be on a tight road course with multiple turns and short straightaways, because under those conditions an ICE vehicle will really struggle with keeping itself in the fat part of its powerband, while incurring a ton of mechanical delays that MSP just doesn't have.
