Replying to: backy (Aug 06, 2008 3:30 pm) That said, I definitely will pay attention to fuel consumption increases reported by the trip computer and more likely dismiss the 'calculated' method - if I'm looking to further evaluate how well my car is running at any given time. |

Apparently the Mazda6 manual transmission (in the outgoing model) just about drops the top gear compared to the automatic. I believe that someone had posted that their manual Mazda6 runs at 3400 rpm at 70 mph. Today I noted that at a steady 35 mph, I was at about 1800 rpm in 4th gear, so the auto would be at 3600 rpm in 4th at 70 mph. That is nearly the same rpm as the manual in 5th. Regarding filling gas tanks, I think some cars have better "fillability" than others. This is one of those little things you find out after owning a car for a while. I have to say Mazda seems to have done a great job on this with the 6. Every time the pump clicks off, it is pretty close to as full as you can get it. Most cars I have had would click off, then I set the pump on a lower rate and a fairly significant additional amount of gas goes in before it clicks off again. With my Mazda6 after it clicks off on the high settng, if I try it on a lower setting it clicks off again immediately and not much can be added by manually topping off either.

Replying to: captain2 (Aug 13, 2008 1:19 pm) Ford is going with dual clutch Powershift in their new small cars claiming 10% better economy over a 6 speed auto. Other than Nissan - who is committing to CVTs?

Replying to: akirby (Aug 14, 2008 4:51 am) Maybe Mitsubishi??? Not that they are of much significance in the US. When is Ford planning to go to the DSG style automatics in the US? The interweb tells me it is already availble on European Fords. |

Replying to: akirby (Aug 14, 2008 4:51 am) Nissan certainly with the biggest - using the tranny essentially line wide - Toyota and Honda using them in their economy champions like the Prius/Civic. It's not like the CVT is new by any means, but something that has been improved/perfected primarily by Nissan. Would not expect a financially and developmentally strapped Co. like Ford to pioneer or even lead the way in the development of any new technologies. I think you'll find that Ford could not use the Volvo sourced chain driven CVT in the Taurus because it couldn't handle the HP increase that came with the bigger DT and was further problematical from a reliability perspective - something that hasn't been a problem in the Nissans since the Murano of several years back. Pooh, pooh the CVT if you will - it does present the driver with a different kind of driving experience - but it is a solid choice in all our FE challenged futures given that there are significantly less mechanical losses vs. the traditonal auto.. If Ford is going to claim the efficiencies of an automatically shifted manual tranny - would suggest they look to VW as well as the Italians for advice in how to do it.....
