Not really. Manual transmissions have an exemption to the braking rate requirements for lighting the brake lights. All other vehicles must light them up whenever slowing faster than a certain rate. There's also a deceleration range where they're optional.The NTSB considers the low gear regeneration braking (sans paddles) with no active brake light to be no different than braking using down shift in a car with a manual transmission.
Surely it would do the same in D?One thing that I did find out that's pretty cool with a gen 1 volt that has forwarded collusion alert. If you have it in L with cruise on if you get close enough to turn on a warning it will automatically kick it to high regen just like automatic braking.
I have a GEN two 2019, as I always have my bike rack on my car I can easily see when it gets a little darker how it operates and yes, if you take your foot off the gas, the brake light will illuminate, as well as with the paddleThat's odd, because if I'm in L and I completely lift the "Torque Request Pedal" HAHA, my brake lights illuminate. 2016 Gen2.
I too use L exclusively. In light traffic, with plenty of notification prior to an impending stop, no brake pedal is required until the stop. In denser traffic some brake pedal may be required to increase the regenerative braking thereby illuminating the brake lights. Even with partial brake pedal, regenerative braking releases at 5 mph. The release can be felt and additional pressure is required to apply the friction brakes.Hello, all, new Volt owner here. (Edit to mention it's a 2011)
When driving in L, and letting off the acceleration to slow the car down- do the brake lights activate?
Having been rear ended in a bad accident in the past, I'm a bit more hypersensitive to the possibility.
Slowing down as much as the Volt can without using the brake pedal has me worried about catching other drivers off guard if there's no indication.
See regs and how the Volt compares here: Brake Light Actuation also compares amount of Volt L deceleration to that of manual downshifting in other cars.
Summary: The Volt's L deceleration is below the limit (JUST below) requiring the brake lights to come on, while a Mustang 3-2 downshifting is 2X greater than the Volts, Accelerating a Mustang in 2nd and then taking your foot off the pedal (no downshifting) also decelerates faster of the Volt in L. All this is to say, the Volt in L meets the existing safety regulations for brake lights and is certainly less of a hazard than at least some cars with a manual transmission that are downshifting or simply not accelerating.
The "I Feel" comment almost always comes up when the poster desires the brake lights to come on while in L, regardless of the law or facts. But it's a feeling rather than a fact. and there is a simple solution, don't use L or tap your brake pedal if you "feel" unsafe.
Keep in mind it is a fact that brake lights do not prevent being rear-ended. An inattentive driver will rear-end a parked car, a car with brake lights on, a police car stopped with all it's lights going. Happens all the time. But if it makes you "feel" safer to have brake lights on, then tap your brakes or drive in D.
I suspect it was a not-expensive part to throw in for a little fun, and in the same vein as "Sport" mode. And also similarly, neither has an particular impact on the performance of the car overall. You're never going to see huge changes to how the car behaves. Sport Mode won't make your car zippier than stomping on the long pedal all the way already would, and the regen paddle won't stop the car any faster or more efficiently than the wide pedal can.Tapping brakes in L means hitting the full decel speed as you fully take your foot off the go pedal. I'm not about to bring the left foot into the equation lol.
Must've been a big enough issue to have introduced the paddle in later years.
And that's the sole set of conditions that the regen actually DOES work to increase range. Whether brake pedal, or paddle, or L, with or without "paeddle", the lowering of road speed also reduces air drag. You can continue to 'coast' at an increasing speed and let the kinetic energy be squandered to create a bigger breeze, or you can slow down, have an easier time pushing air aside and 'bank' that air drag reduction as more regenerated electrons."L" may be beyond useless... I would contend that it actually reduces your range/efficiency since it is needlessly regenerates on slight downhills i.e. your car starts picking up speed on a slight downhill, so you lift off the accelerator. The car will regen in L wasting your momentum. In D, the would regen far less and maybe allow your speed to increase slightly, but it would maintain most of the potential energy without needlessly (and wastefully) converting it to electrical energy to be stored in the battery only to be transformed once again when the road inevitably flattens out or starts up the next hill...
I agree. I verified using the same method on my 2017.I've confirmed my 2017 Volt lights the brake lights in L. Confirmation done at night and watching the reflection off signs behind me when I let off the throttle. It also triggers the brake lights when using the regen paddle. Same confirmation method.
Note that post #23 was speaking about the Forward Collision Alert (FCA) system, not to be confused with the Ultrasonic Front and Rear Parking Assist (UFRPA) or the Ultrasonic Rear Parking Assist (URPA) systems, all of which are "if equipped" features (i.e., extra cost, not all cars are so equipped). Information on the FCA was first included in the 2013 owner manual, so it’s doubtful your 2011 Volt is so equipped.Either I ran out of nerve or the car didn't do what another poster had claimed, saying the volt will automatically apply braking when on cruise and approaching a car in front using proximity sensor info.
I got uncomfortably close to the car ahead on cruise/L before I manually eased off, I'd say 10 feet at 65mph (less than a car length). 🤷♂️
