i would like to see a source on this. i often see DCT or CVT versions of a car that are more efficient, but afaik, traditional fluid coupling automatics still have a hard time beating a manual transmission in the same car.
- NikolaeVarius 8y agoIt's reached the point the inefficiency of humans reduces the overall fuel economy of a manual to equal or below a modern automatic https://www.autoblog.com/2010/08/18/greenlings-why-do-automatic-transmissions-now-get-better-fuel-e/ https://www.autoblog.com/2010/08/18/greenlings-why-do-automa...
- twblalock 8y agoTraditional fluid-coupling automatics are not the only ones on the market. A lot of cars now have dual-clutch automatics, and there are others that combine a fluid coupling with a computer-controlled clutch. Fuel economy tests in many different countries have confirmed that automatic transmission can indeed be more efficient than the manual transmission in the same car.
- rootusrootus 8y agoModern automatics spend very little time with the fluid coupling. They engage a lockup converter as soon as possible. Combine that with more gears and a computer choosing the shift points, and they are now more efficient than a manual transmission. It's been that way for perhaps the last 10 years or so. Want a source? Start perusing the manufacturer specs and fuelly pages for cars that still have both options.
