You can gear down in a manual transmission ICE to achieve similar reduction effects, but I doubt they will bring back manuals.

- kevin_thibedeau 2y agoI have a newer automatic ICE and they use cylinder deactivation for engine braking on low speed coasting.
- oynqr 2y agoIsn't cylinder deactivation for when you are at constant speed at low throttle?
- landgenoot 2y agoThey open the exhaust valves of every cylinder while coasting. Therefore, the engine keeps running, but there is no combustion. You can see your live fuel consumption go to 0 when you lift the gas pedal on a modern ICE car.
- kjkjadksj 2y agoThat is whats always happened when you lift your pedal on a manual car at least.
- garaetjjte 2y agoCylinder deactivation is for reducing losses when coasting, not braking. You want more losses if you actually intent to slow down. Some trucks have retarder that open valves at TDC, so it dumps energy from compression instead of pushing piston back down.
- masklinn 2y agoThat is significantly more involved (and for most people less comfortable) than regen braking, which just... happens. Many (most?) EVs will also do blended braking when using the braking pedal, so even when you brake "manually" you're still not using physical brakes unless you really step on it.
- redwall_hp 2y agoThis is available on CVT vehicles too. My Civic Sport Touring has paddle shifters that you can use to simulate gear changes, which is also convenient for winter driving. On the latest model year, which is a hybrid, the paddles control regenerative braking instead.
