Replying to: flatpick (Nov 07, 2005 6:42 pm) Paddling vs Full Auto on the fun level depends. Having to watch the RPMs to shift can get tiresome in stop and go traffic, but if the road is clear, Paddle shifting is the only way to drive.

Replying to: trispec (Nov 17, 2005 3:07 am) Shifting with a clutch is the only way to drive  Plus you get the added HP and higher revs in the 8 - and with a VooDoo shift knob the shortest, tightest manual tranny I have ever used - and that includes both of my S2000s. Now if I had to crawl in traffic, I might feel different.... Still getting 13-15mpg commuting about 25 miles round trip each day, but driving the car in the manner for which it was designed  Dennis

Replying to: dwynne (Nov 17, 2005 6:21 am) Paddle shifting is quite fun though. You know that's how real racers shift, Indy and Le mans types at least. It's just the NASCAR folk who force the manual standard stick and clutch to remain in use. Professional drag racers went fully automatic years ago. Stick and clutch vs Paddles shifters is like carburetor vs fuel injection I think. At first everyone complains about loss of power and added complexity, but eventually the efficiency of the later over the former wins out. OTOH, when I want to just cruise around as easy as possible, full automatic is real nice too. |

Replying to: trispec (Nov 17, 2005 9:41 am) The new 6 speed auto would be more attractive, but I still can't get around the lack of revs and ponies with the 8's version of the auto-box. Would I really miss it, don't know - but I would KNOW I was missing it  The 8 (and the S2000) is a true joy to drive with a stick - just a great transmission and 8k-9k redline. I wish you lived where you could have one too. The good news is having an auto does not seem to cost anything at the pump - either way we get dismal numbers. Dennis

Replying to: trispec (Nov 17, 2005 9:41 am) It's only a small step now (06 auto cars) to get a 9000 RPM torque converter. When that happens, the auto will be faster than the manual! It might be a tad heavier, but there is no letup of accelleration when it shifts. I'm not sure I like that, though my first auto equipped car (2001 Pathfinder) is winning me over! I wanted leather and it was only available with the auto. Of course it is a SUV, not a sports sedan.

Replying to: pathstar1 (Nov 17, 2005 2:24 pm) NASCAR by his estimation controls the entire US manufacturing industry because Stock car racing is the ONLY thing that's holding off the imports from completely taking over the US market. Ultimately, stick and clutch is the cheapest way to offer the maximum power, but shifting gears via a clutch is not necessarily the best way nor the most efficient. |

Filled up yesterday and got my best mileage so far. Around 1,800 miles on the car now (6mt) and got about 16.25 mpg. This is the best I have gotten for just commuting. Could be the cold weather, could be the mileage is getting better with more miles on the car. Could also be the pump shut off too soon - but I filled up at the same station and the same pump (the one I know has the working lock) as I always do. in the event this was the case, then next time I should see worse than normal mileage.

Replying to: dwynne (Nov 18, 2005 10:19 pm) After 3500 miles with my RX-8 AT using full auto, no paddle shifting, no fast take offs, and staying under the speed limit, I pulled 17mpg. Full auto constantly shifts to the minimum speeds for 2nd, 3rd and 4th and drops rpm to 1500 or less for maximizing coasting. You end up riding the brake a lot more since there is little engine breaking available in 2nd, 3rd and 4th at low rpm levels. But driving like that all the time would be a horrible waste of the RX-8 resources and probably would cause carbon build up in the engine systems along with extra brake wear. Driving with paddle shifting between 2500 and 4000 rpm strictly, I get 15mpg. This is the best balance of enjoying the RX-8 resources and traffic reality during the day. Driving with paddle shifting between 4000 and 6000 rpm strictly I get 11 mpg.  This is hard to do on a practical level in the city. Late nights is the only possible time and even then traffic can get in the way.
