It's official. Manual transmissions are making a comeback.
There are lots of great statistics at the Government CAFE web site. Lots of compiled data on cars going back to 1977 (and some even older.) One interesting trend tracked is the percentage of automobiles with automatic transmissions. In 1977, 84.1% of all new cars had AT. Under pressure of demands for improved fuel economy and increasing consumer preference for import cars, that number dropped to 75.0% in 1987. Then imports went upscale, ATs became more sophisticated and fuel got cheap. By 2002, 88.5% of new cars had only two pedals and the imminent demise of the manual transmission was widely predicted. Then something funny happened. There were rumors of rebellion in the ranks and increased reports of drivers demanding control of the gear ratios. In 2003, the percentage of cars sold with automatics dropped precipitously to 82.4%. The CAFE site is now reporting a further drop in 2004 with the lowest percentage of AT's since 1991, 79.6%. That means that the number of cars sold with manual transmissions increased 77% in only two years and a clutch is now found in one of every five new cars. In terms of sales, this trend actually surpasses the much touted return of rear wheel drive and the movement is broad based. While keeping in mind that the politics of fuel economy can skew the definitions pretty badly, the trend is apparent in domestics, Asian and European imports. All are selling manual transmissions at levels that haven't been seen in a decade. Almost half of all European cars are now shifters, the highest rate since 1988. Will this be a long lasting trend or a brief flash? It is still too early to tell but it certainly shows that the old MT is going to be harder to kill than it once appeared. The auto companies have now learned that there is a solid base of buyers who prefer to shift for themselves and the increased availability of this option is sure to follow. http://www.nhtsa.dot.gov/cars/rules/...erCarFleet.htm |

It's kind of a bummer because I like responsiveness of manuals but the milage*power level is falling behind some automatics. Regenerative braking, continuous gear ratios, ultra-lean burn, and cylinder bypassing need to be coordinated with an AT. The decision was much more clear-cut a few years ago when you chose between a peppy 5-speed manual or a sluggish 3-speed automatic. Now cars like the Accord Hybrid make the decision tough. If we get fuel cells in marketable condition there may not be multiple gears anymore. You'll just have a knob to select how much regenerative braking you want when you take your foot off the throttle. Crank up regenerative braking and you'd have lightning fast response to throttle changes. |

Yes, I wonder how they (NHTSA) are defining "manual". Some of the ones you listed are typical torque converter ("slushboxes") where they just add a manual shifting mode. Others have actual manual trannies, just with an electronic clutch, ex: BMW's SMG. I believe your "Easytronic" is the latter? I wonder how many folk who buy the tiptronic type actually manually shift. When I've driven those, I get tired of the novelty in the first drive and just end out driving them like every other automatic. |

I have a Honda Civic Hybrid with CVT, and I understand how it works. The IMA is fixed to the crankshaft, so they are both turning at the same speed. The CVT is a steel belt on movable "pinch" pulleys to provide the variable ratio. I don't understand the mix of two electric motors and the CVT in the Escape. Short of buying the service manual, can you point to a decent reference for how it really works? I've seen some misguided crud, but no real explanation. I assume that it is the same as the Prius, so reference to that would be good, unless I can spot a discrepancy. -- --- Clarence A Dold - Hidden Valley (Lake County) CA USA 38.8,-122.5 |

Try this treatise: http://home.earthlink. net/~graham1/MyToyotaPrius/Understanding/PowerSplitDevice.htm I can't vouch for it being 100% correct, but it is similar to what I've read before about the Toyota hybrid drive. Basically, by varying the motor/generator1 speed, one can control the ICE rpm. It's pretty neat, but also complex. 2 high-power motor/generators.

I wonder what kind of mileage the civic would get if it just had the 1300cc engine, and no IMA. It is very simple to understand, and rather obvious in operation. I don't understand the Escape very well yet. Definitely a different animal, and a precursor for the heavy hybrid (no pun towards the weight of the SUV). The electric-only mode could be extended with a heavier battery set and different logic so that it could operate completely electric and be charged at night, and yet have the gas engine for long distance usage. I have seen 99mpg on my average mileage display over a 10 mile stretch of commute traffic. Then the engine starts, and the mpg plummets ;-) I picture today's Escape as a Gas-Electric Hybrid, where the next generation might be an Electric-Gas Hybrid. -- --- Clarence A Dold - Hidden Valley (Lake County) CA USA 38.8,-122.5 |

By that way of looking at it, SHS has two transmissions, like pretty much all cars. The planetary "power split device" is a skewed differential and could have been made like a typical differential if ruggedness weren't important. No gears ever shift, there are no clutches or belts or hydraulics or solenoids or forks. It is all fixed gearing, which makes it different from automatic transmissions. The device should be bulletproof as long as the lubricant is kept up, without the weaknesses of manual trannies (no synchros, no clutch, no gear crunches possible). The way I describe the system is to visualize an engine connected straight through to a differential. Instead of wheels, there is a motor/generator on each side of that differential. Connect another conventional differential and wheel setup to one side, and there you have it. Mike |
