@jtsanders - you really would knock a car off the list because it downshifts going up a long steep hill? We have a hill with about a 6-7% grade approaching our house for the last 3/4 mile up that road. Our 1998 Camry doesn’t downshift on the hill. Our 2010 Mazda6 does. Which would I rather have on the hill? The Mazda any day. Why? Well, the Mazda is downshifting because the speed limit on the hill would require the car to be lugging in 4th gear, where it normally cruises on the street, but in 3rd it runs fine. The Camry’s gearing, being different, lets it run along in 3rd the whole time.
What’s the difference in feel, though? The Camry has VERY little responsiveness going up the hill. It struggles to accelerate, and has for many years. The Mazda, on the other hand, is seemingly eager and ready to go. Nudge the gas a bit and the car starts accelerating very nicely.
