You need to read up on Hybrid "cruise/coast" when you apply brakes (not BREAKS) the hybrid engine turns off fuel/engine and your wheel turn the ICE engine and uses engine compression as part of regenerative braking & braking to recharge the battery...I live on a steep hill and purposefully take my foot off the "brake" and the regenerative braking slows the Hybrid down recharging the Hybrid battery. The display shows the regenerative braking come on. When you slow to a stop the ICE restarts. Even Ford suggest brake disk will have a 3 to 4 times life due to Hybrid degenerative braking not using your disk brakes, unless you are pressing the brake peddle.I agree with most of what you say, except about stopping power-
(If you are at 80 miles an hour in a Maverick and press the brakes hard, you will find the automatic greatly contributing engine braking/ stopping power., that is not there in a manual transmission.).
I would say that anyone that has experience driving a manual would be able to utilize downshifting, breaking, and adjusting engine speeds to control vehicle speed and control that would rival just about any automatic, in fact, unless the vehicle has regenerative breaking, I would argue that an standard automatic applies almost zero breaking, as they are usually programmed to allow the vehicle to cruise/coast for the greatest fuel economy and reduced transmission wear.
Some diesel trucks (F250 ^, 2500 ^ series GM and Dodge Ram) may have tow assistance not found in common passenger vehicles. Some track racers would also disagree with your stance on the speed and accuracy of up/down shifting as desired, especially during a competitive driving situation.
Anyhow, Edge Haley, thanks for the dialogue! Have a good day.
I'll have to try 80-0, but the Hybrid transmission is so quite doubt you will be able to feel the gear changes. But rest assured you speed control the Hybrid automatic transmission. But positively the Hybrid contributes to braking...as the engine compression occurs, though you can not hear/nor feel the Hybrid automatic transmission I'm confident it is down shifting.
In the Porsche PDK, from 120 mph, full brake, it shifts from 7th, to 6th, to 5th, to 4th, to 3rd to 2nd gear in no less than 3 or 4 seconds...and you can see the gear changes display, having a monumental effect on stopping power with use of the engine compression...can't do it that fast in any manual transmission. It is different in a Hybrid but the principle is the same, engine compression contributes to braking. You only see this in a Hybrid, not an EcoBoost, and again the display shows you the compression braking.
Regarding auto racing, I've been through all 3 of the Porsche Advance Driving Schools, and Sprint racing series....Probably 4 years ago manual transmissions pretty much disappeared in the Sprint racing series all over the country, NO ONE drives manual transmissions in competition (maybe exception of NASCAR, which I don't follow) mainly because the automatics are so much quicker at down and up shifting....for safety purposes and efficiency Porsche took all manual transmission cars off all their Race Training tracks, all cars are now the Automatic PDK's (Carson, Calif, Atlanta, etc.)
I would have been in your school of thought until driving a very high performance car for 3 hours. I too like shifting gears. But the current day performance transmissions shift to the appropriate gear quicker than you can possibly think.
