Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Leading evidence: 'last car i had' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'last car i had' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Run so much better' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Suggestion
For example, ever noticed how the car always seems to run so much better when it's freshly washed and waxed?
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

No such thing exists for these cars. Also, none of the CVTs that have been built by other manufacturers are yet able to handle the torque/power these cars make. So far, the maximum power that production CVTs have been able to handle is around 250hp before they implode.
Audi made the B6 A4 with an optional CVT for two years or so then abandoned them because they were crapping out left and right.
The reason I asked was that I thought F1 banned CVT in '93 because of its advantage over semi-auto transmissions. It's been 20 years, I would have thought that CVT would have made its way to today's sports cars.

Figures a Japanese manufacturer would finally get it right. Besides Mercedes, none of the German manufacturers can build an automatic transmission to save their lives.
I'm old school and prefer more driver input, but, that doesn't mean that CVT couldn't be made to be superior in performance. For enjoyment, I prefer my 6spd but if I were racing I'd want a CVT as it appears to manage traction and torque better.
What are your reasons for not wanting a CVT?
Well, my personal reason is I prefer a manual trans.
But CVT's have not really progressed in the performace arena, I think you are better off with a PDK type system.
Are you saying that Formula 1 is not the pinnacle of performance? If CVT wasn't banned because of it's performance advantage, it would be in every F1 race car.
I bet F1 banned it do to the enormous cost of developing one. The KERS systems are pushing new ground.
CVTs are yesterdays news no good PR for them.
Plus all of the cars would sound like angry bees on crack running at 15000 rpm everywhere while melting CVTs.
Me too!
The experience was like driving with a constantly slipping clutch. Would have preferred a straight auto to that sentra thing.
Although... it was the last car I had to drive before my 996. So as far as pallet cleansers go, perfect.
CVT does have some advantages in some cases. For F1 it could be made to work, might be worth the development costs, because the CVT can better accommodate the very narrow power band F1 engines have. 6 and now 7 speed manual transmissions are an attempt to provide enough gears to keep the F1 engine spinning in its power band under a wide variety of conditions (vehicle speeds).
In street cars the engines of cars that have a CVT are designed/tuned to reach an optimum rpm range and stay there as this is where they are most efficient. These engines need a CVT to deliver their best.
Just fitting a CVT into a car equipped and designed/intended to work with a non-CVT transmission would result in something less than the sum of its parts.

Macster.
I felt a little snarky yesterday and I didn't have any meetings or anything going on at work to properly vent.
Not to start another oil discussion, but same here. I switched to Rotella from Mobile1 in my old Audi S4 and several small oil leaks that had been annoying me for as long as I'd owned the car magically went away. The 911 seems to really "like" it as well. Maybe it's all mental, but that good enough for me, since 90% of the "problems" with most people's cars come from their head anyway...

As I'd guess do 90% of the cures.
Sincerely,
Macster.
The only place a CVT has found an accepting audiance is 'snomobiles'. Last I looked, the p-car has tires on 4 corners, not ski's in the front or a track in the back.
Yah the PDK is a real flop.
There you go being observant again.
Since this thread is about pouring out a thousand words with no avail. May I suggest posting pictures so that we can partake in a picture is worth a thousand words?
