I wonder if this will spur mandatory regenerative braking in all cars, eventually, as a means of reducing pollutants?

- thatcat 2y agoYou 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.
- jakelazaroff 2y agoMaybe, but that still isn’t solving the root of the problem. There are a ton of ways in which cars harm us — exhaust, brake dust, tire dust, etc. The only actual solution is to reduce car usage.
- Aachen 2y agoWhy can't we have both? Until we do convince uncle Jack and his friends to stop voting for things against humanity, at least those things could be made less harmful
- jakelazaroff 2y agoWhy do we think we can convince Uncle Jack to vote for mandatory regenerative brakes?
- Aachen 2y agoBecause it's less invasive (from their point of view) than sitting on a train with, eww, other people I'm genuinely thinking of a particular person in my family who was one of the first to have a regenerative brake (for financial reasons, probably a tax reduction by going hybrid idk) but will also be among the last to do anything for the greater good
- kjkjadksj 2y agoYou can do this in an ice with a manual transmission.
