Is it safe to drive a chevy volt(2018) on L-gear all the time?

    I drive a 2018 chevy volt on L-gear since a few weeks. Wondering if it would cause any long time problem if I keep driving it in Low gear

    Not a problem. I have been driving in L for over a year with no issue. It just changes the regenerative braking to be more aggressive, giving you something closer to one pedal driving. Do not confuse it with the L functionality of an ICE vehicle.

    Thank you for the clarification.

    Greetings:. So is it the same for all Volt production? Namely my 2014. Why do we have both L & D then? Sorry, I know nothing.

    General motors found it a bit costly to redesign a selected lever for their EV's so they stayed using the same one they use in ice cars. With more electrification of their fleet we may see a change in future models. This was GM's way of keeping cost down.

    I would say yes, it’s the same. We mostly use L mode in our 2017 Volt but I will sometimes use D mode on the freeway with light traffic since it gives you a little more of the coasting feel ICE cars give you. In addition to what Timothy said above, I would also add that GM wanted the Volt to be familiar to drivers who might be new to a plug-in. I remember some of the confusion around the joystick shifter in the Prius back in the mid 00’s when they redesigned it. Personally, I like the traditional shifter a little more but could go either way.

    I drive my 2011 Volt on L all the time. While I haven't heard of or had any mechanical or electrical issue, the habit leads to expect strong engine braking on other cars or even in the Volt when I select it in D by accident. I tend to use less braking and when I drive without L the car fells runaway and brakeless when coasting. Tailgaters also get surprises since the L does not turn on the brake light when engine braking (the BMW i3, for example, does).

    GM changed that with the Gen 2. My 2017 Volt does activate the brake lights when in L gear and I take my foot off the “gas” pedal (and when I use the regen paddle). I have visually confirmed this myself.

    I noticed that with cruise control on and in L, the car won't go beyond what it is set at going downhill. Does this use up or prevent it from better mileage. In L, is it using more energy starting from stop? Just wondering. Gracias,, Bueno Bye..

    There should be a some improvement since the car in L would try to recharge the battery while going downhill while if going on D it would not so the extra energy that could have been harvested would be lost to the drag while going in a higher speed downhill.

    Besides that, the Volt has almost no engine braking when driving on D, so the car would pickup a lot of speed when going downhill which could be dangerous, so driving in L should be safer when driving downhill. I've already been stopped by the police for speeding while going downhill without noticing the speed increasing (it was a Dodge Charger, though).

    It is perfectly safe to drive in L mode. I've driven in that mode since I've bought the car. I've had no issues with it. The cruise control works just fine in L mode. the only thing that does is increase the amount of regenerative braking

    The "D" position might as well not even exist in my application. I've used "L" exclusively since about day 3 of owning my 2014 Volt. My brakes will probably never need to be replaced! I live in an area where straight roads don't exist more than about 300' in a stretch and regen does 95% of my braking. Every car or truck I've owned has been hard on brakes and brake jobs are expensive. I love regen braking!

    The only thing "L" does is engage the electric drive motor as a generator whenever the accelerator is not employed, whether by removing your foot from the pedal or downhill speed exceeds cruise the cruise setting. It's a gain, not a loss. Using "L" from a stop doesn't affect the energy necessary to accelerate from a dead stop or any other speed for that matter. In "D" and with cruise control set while going downhill, the only "advantage" you will see, is you may get to the bottom of the hill faster than your control is set to...but your battery will not receive any of the charge it would have if you had been driving in "L" under the same condition.

    I assume, because the car is basically drive-by-wire where the computer controls everything, there should't be any difference going downhill whether driving in "L" or having your foot lightly on the brake. Although "L" guarantees not to use the physical brakes, I would hope the car is smart enough not to do that as well when braking lightly. I understand that braking "hard" will engage the brakes but, a light touch should be the same driving in "L". I'd like to hear some confirmation from GM that this is indeed the case.
