LX570 is a hit up here with friends and family, several people have ended up driving it around. They like the power, haha. They all drive 4 cylinder cars with start/stop. I've been riding in the back a time or two, cushy. I also have noticed---yayyyy---there is a tad of exhaust V8 rumble back there!! I thought it was literally silent.

Yes. If I were an EV driver I'd just keep a nice ICE car/cars because I love them too and for trips. Problem solved. No big deal at all, lol.

 

Start stop is the worst invention in automotive history IMO

 

it's a nice idea in theory, me liking it or not mostly just relies on how it's implemented... like it can often be tricky to drive in a smooth "normal" way depending on how the system is calibrated

on the GLE450 for instance it's actually an incredibly seamless transition, like how a prius engine just buzzes into life, but on that car at least it'll cut the engine before you even come to a full stop! it makes things like stop signs or very slow traffic potentially irritating since there's sometimes a delay between taking your foot off the brake and when the engine is running again

 

Years ago I met a client. He was driving his TDI Q5 and I remember stalling at the traffic lights. Recently I drove a Chevy Equinox and t was super annoying. Just not something that ruins the experience. Just adds to the cost as well

 

It's bad.

I can't even imagine how bad it would be on a rough, small engine.

It's a nightmare on a 6.2L Yukon with 24k miles on it, and that's quite a smooth V8.

It's just stupid. It shuts off and then restarts 10 seconds later bc of the damn HVAC half the time, not because you take your foot off the brake.

Thank GOD there's a physical button you hit every time not hidden in menus to shut it off.

 

That could also mean the battery is low, or the alternator is weak.

Agreed.....but GM won't program their buttons to shut it off and KEEP it off every time you restart the engine. I've heard it may be an EPA requirement to deter drivers from using the feature.

 

like it shut off as intended but never turned back on? that's a major yikes

on the GLE at least if you come to a full stop it works great, with the 48V system and ISG it can power electrical accessories (including the electric A/C compressor) for a long time, and the startup is near instantaneous and perfectly smooth... the software just lags sometimes with rolling stops and very slow moving traffic

 

it's really just because the car gets hot again right away, and the A/C compressor in a yukon still requires it to be spun by the accessory belt... some cars have an 'eco' setting on the climate control to prolong the engine turning back on

 

The shut-off system is designed to detect when the vehicle is not charging properly (low battery, low voltage, low alternator, or other electrical issue) and cut the engine back on more quickly...or not shut it off at all.

 

It also comes back for AC since GM doesn't use electric compressors.


It's a very dumb "feature" and every time it activates it depressurizes the oil system. Extremely stupid. My 4.0 has it but on that car it remembers if you ever turned it off and leaves it off, I actually have no idea what it even feels like in that car since I disabled it on the test drive.

 

Some GM cars you can’t turn it off. I remember reading about someone with a GM who would not come to full stops at stop signs so that their stop start wouldn’t stop.

add complexity and you add problems. What happens if the start stop completely fails, does the car then fail emissions?

We were driving around. Stop and go and stop and go and then we were coming to a light to turn and we stopped and the car just stopped/stalled, and just wouldn’t start back up. So he had to restart the car and off we went. Then we had to find diesel which was a pain in the rear.

 

Good ole reliable Toyota 5.7 V8. Mpg??? Not important🤣. Due to bigger tires, waze indicated speed was 96mph.

 

GM started adding a turn-off switch around 2019 0r 2020 because of customer complaints (my complaint, on my 2018 Lacrosse, was one of them)

Yes...I used that trick a few times on the Lacrosse (which did not have a shut-off button). But you had to stop back far enough, and have it clear enough around you, so that you could very gently feather the brake pedal to cause a very slow 1-2 MPH creep. I have always have had a good feel for auto controls, so for me, it was simple and came naturally. Still didn't like the fact that I had to do it so often, though, and I let Buick know.

 

Forget ALL THAT crap. Keep your ICE-only Mercedes while you can.

In theory all that sounds great even if someone isn't a fan of it personally, but no. This thing will burp and sputter all the time. Mercedes is having issues with these 48V systems. At least according to my guy at the dealer. The Indys know about it but they don't see it to work on yet because they're still so new. I do not want a system that designs the engine to turn off the most efficient way possible as I'm rolling as I take my foot off the gas, just what a disaster. It's not there for fun, it's there to save fuel. Always remember that.

How bout, just leave the V8 alone in the S-class and let it get the excellent 30MPG HWY it was gewtting? WTF is the problem here. (rhetorical). I know someone who keeps saying they're gonna trade an absolutely stunning W222 S560 for a new W223 S580. I keep warning them. It hasn't happened yet. Bit's 471hp 7300RPM V8 also gets 30MPG highway.

Right, it's just a huge truck with a huge engine etc.... HVAC doesn't even have to be blasting for it to start it up after shutting off for a whopping 8 seconds. It's a huge, hulking vehicle. It needs power, gee whiz. It really is pathetic what automakers have been forced to do here because of all of this emissions garbage. And I don't care what the automakers say, I don't think start/stop is great for the engine either.

 

Love this. 130k on my 5.7 and she's singin' like a lock!!! Planning to take her as far as she'll go. I also couldn't care less about gas mileage.
