Yeah that...not one !!:wink:Agreed...the transmission is the weakest link in the the current Smart drive-train...can't wait to experience the redesigned 453 model...RIP to the current tranny!
It's funny how many forum members like to defend the driveabilty of the current transmission...the simple fact is...there has never been a single automotive publication that has provided a positive review of the current Smart transmission...not one!
Yes, but as they grow more complex they are also increasingly complicated to repair and rebuild.Auto transmissions are becoming much more sophisticated every day compared to the ones most of us grew up with. Obviously the smart doesn't use one, but some newer cars with current auto transmissions do get better performance, and in some cases, better fuel mileage than their manual counterparts - and more will be coming along, in large part due to computer controls and higher EPA mileage requirements in the US.
Oh, not always. I thought the issue was they weren't as efficient and robbed power from the car.... now we want to talk about more complex and complicated to repair - can't be any worse than our little $15K cars which can cost half that to replace a failed engine.Yes, but as they grow more complex they are also increasingly complicated to repair and rebuild.
And they'll always be larger and heavier than their manual counterparts. So these auto's still have a long way to go if they're going to displace manuals and self-shifting manuals in economy vehicles, and performance cars.
We can also technically improve the mpg's of a manual trans by adding 6 and 7 speeds to them...
But that's in an expensive Corvette, a heavy Corvette, not in an economy car. Notice they also offer a 7-speed manual transmission too. In the current Corvette (not a Z06) it gets up to *29* highway MPG's. *29* in a Corvette!Oh, not always.

Anyway, back to the topic - great article today about the new GM 8 speed auto going in the 2015 Z06 (heresy in itself, putting an auto in a Z06) - developed and produced at GM's transmission plant in Toledo. The engineers were told the new transmission could weigh no more than the six speed auto it replaces; it doesn't - it weighs 8 pounds less, and will handle the ~625 hp from the new Z06 powerplant, which the older GM 6 speed auto would not. Auto engineering is rapidly evolving and a lot of the old "truisms" just don't hold up anymore - 3K mile oil changes, anyone? :wink:
New Corvette first to get new 8-speed GM transmission built in Toledo - Toledo Blade
Whatever the industry decides, based on profits or fuel economy, that's fine. As long as we are willing to still be fair and honest in our assessments of the benefits and drawbacks of both technologies.But you also mentioned performance cars - doesn't the Z06 count...
Let's wait until the EPA numbers are in for the Z06 automatic - I think you'll be surprised. We're comparing apples and oranges here in the Vette and the smart, don't you think?
As far as offering traditional manual transmissions, yes manufacturers (some) continue to do that in their cars (some) but the number that matters is the percentage sold with manual transmissions. Right now, ~7% of sales in the US. Not really worth putting huge amounts of money and engineering resources into the traditional manual transmission for most manufacturers, unless in a halo car like the Corvette. Even Porsche seems to feel the manual is on its way out: http://www.smartcarofamerica.com/forums/f7/swan-song-manual-transmissions-62793/
I certainly enjoy the manual transmissions in our Corvette and Mini - but the next Vette we get will have that new GM 8 speed auto in it.
I can remember the Sony Betamax supporters declaring it was the superior format right up to the point it disappeared. It was, technically, but consumers preferred VHS.
