Uhhh, manual cars have worked like this forever. In first gear especially the braking when you let off the gas is enough to be jarring if you're not gentle

- alistairSH 9y agoYes, but there is no computer turning mechanical engine braking on and off based on some set of non-trivial conditions.
- slackingoff2017 9y agoEhhhh that's not quite true either. Above a certain rpm the engine cuts fuel completely and engine braking is strong. In cars with electronic throttle control the computer might also open the throttle to maximize energy consumed compressing air. As you pass through that cutoff range the engine starts firing again, maybe 700 rpm above idle. Engine braking stops being effective when this happens. Also, newer cars don't do a full fuel cut when engine braking with a cold engine or if the catalyst is getting too cold to work. So sometimes engine braking isn't very strong. Basically you can't rely on engine braking so when you're doing it your foot usually hovers on the brake pedal. This isn't any different than the hybrids
- alistairSH 9y ago#carbureted4life Whatever the case, I've found engine braking to be fairly consistent in manual transmission cars at a given speed/gear. But, I've never thought I could rely on it to bring me to a stop in a parking lot. It blows my mind that an EV driver would think that.
