Auto StartStop

[Gregs24]

The Start/Stop has never been triggered in my 2024 GT. Not sure if it could be because of the climate here (but there are cool days in the winter that require heat, not A/C) or a missed recall to erase a "bug" in the programming that stops it from working. Anyway, after reading all the conflicting opinions, I have decided to include setting it to "off" in my custom mode. I wonder if it will start working in "Normal" mode after some future software update.

I drive very infrequently in city stop and go traffic.
My typical trip is 10 to 20 miles round trip (occasionally longer), the shorter ones with surface streets outbound and freeway return, longer ones with freeway both ways and some surface streets at the far end.

My cumulative MPG is 21.2 after 4824 miles.

I think there was a fault in some of the early S650 S/S systems that were subject to recall.

I think job 2 2024's had SS. Mine was built 12/14/23 job one no SS.

I think some early Job2 cars didn't have it either and then there was a break in production for a while with S/S Coyotes the limiting factor (not sure whether the engine or transmission)

Nice MPG !! Mine im lucky to get close to that..

I think your local optician stays open late on Friday night, best you pay a visit

Im so sorry you have to put up with yourself, LOL!

with as well as better cars than ANYTHING to come out of UK from the automotive product perspective.

That is quite a ridiculous statement.

Your '24 has ASS? When was your build date?

Window sticker says Blend date Feb 16 (120240216).

And, on behalf of American ingenuity, you have your little S/S toy to play with as well as better cars than ANYTHING to come out of UK from the automotive product perspective. You're welcome, LOL!

That might be stretching it Mr Dog. They produced the odd nugget from the piles of crap they foisted on the public.
Granted, some had US V8's. AC, Jensen, Bristol, etc. Which is only fair, they gave the Merlin to Packard.

My '24 has ASS. It's quite nice ASS too.

True, since they were desperate to have someone, just anyone save their asses at the time Merlin was given to someone that could produce them in quantity. And true, some had U.S. V8's. Yep, the MG's, Austin Healeys, Triumphs, and other rust bucket, electrical nightmares was the best they could do for the public buyer. What disaster to this day.

I found this in my tune for my 25. Might try to disable it and flash it and see if we have the magic button...

Erm we have made cars since the 1970's you know!

Let's just pop Lotus, McLaren, Jaguar, Land Rover, Bentley, Rolls Royce to name but a few inferior products

Original S/S and full hybrid are worlds apart from an engineering point of view

Is a hybrid simply a longer duration between stop and start?

No, they can drive under electric power alone.

Mild hybrid (MHEV) - ISG 48v system, limited movement under electric power but engine off when slowing / stopped and electric motor provides a torque fill effect. 5 to 10 mpg improvement over standard petrol.

Full hybrid - (FHEV) small HV battery up to around 2kWh which allows low speed running all electric then engines kicks in as required. Regenerative braking tops up the battery and expect fuel consumption of around 50-60mpg (example is the Toyota Prius)

Plug in hybrid - (PHEV) as above but with a much larger battery of around 15 to 20 kWh allows full electric running for 40 or 50 miles then reverts to FHEV above. Can be extremely economical depending on the source of the electricity such as domestic solar panels.

When driving, a FHEV and PHEV will stop the engine whenever not required such as going down a hill or coasting and also regenerative charge when braking. This is even on a motorway and makes a petrol engine at least as economical as a diesel engine.

I have an A10 transmission and a 3:15 rear end but I think people tend to mis-judge that set up.

No, I wouldn't go up against your car unless it's a manual, but the A10 is rather amazing when it downshifts into a low gear and takes off hard and fast shifting super fast until I let off the gas.

I'll tattle on myself in that the car has seen 150 and it got there quick. Around town, it basicly almost idles around in a high gear because it has the torque and power to do that. I can put it in sport mode and it completely changes it's personality and gets very quick driving and handling. I can't beat everybody by far but it isn't a slow set up either. Just sayin'.

I'll find out tomorrow because I'm leaving on a thousand mile round trip with 90% on the highway. I'm predicting at least 24+ mpg driving how I want. The radar detector will be my little buddy.

You will definitely exceed 24 MPG. I have the manual with the 3.73, and when I get on the highway in 6th gear right after a refill, I'm approaching 24 once I'm up to speed.

When you're not hammering the throttle in these cars, they're surprisingly efficient. But, as mentioned, that's not why we bought them.

Im on full e85 and I get about 8-10.

You're right. I'm at my destination and it has averaged over 25 while not trying at all. On the way back, i will keep my foot more disciplined and we'll see what it will do.
