Auto StartStop

True. We built the Merlin for them to help save their asses.

You have already had posts removed by the mods. The next step is more drastic. Calm down.

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.

Even in your description you indicate the combustion engine is stopped when predetermined criteria is satisfied and restarted when needed, in effect a longer duration between stop and start cycles. But, it seems, automatic stop and start may have fallen out of favor in the auto start stop thread?

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.

No argument here. And I still think the P51D was the most beautiful, looking and sounding of all WW2 aircraft.

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

Lots Of Trouble Usually Serious?
McLaren, nothing without Bruce, a Kiwi.
The others, Indian and German owners.

McLaren cars nothing to do with the old race team

Non-UK owners now but still made and designed in the UK

Not sure what your point is?

Seems we stopped talking about the automated feature and started talking about another.

we discussed the ‘wear and tear’ when misusing the standard always stay started function and then you indicated that hybrids are light years ahead of the old method, which i in turn rebutted with simply a different duration.

My point was hybrids turn on and off the engine far more than S/S systems such as on the Mustang. S/S obviously only happens when stopped moving but hybrids do it all the time. In a 50 mile journey a hybrid may turn the engine on and off 50 times or more. If the engine wear was an issue on standard older S/S systems like the Mustang then hybrid would be much worse, and it isn't.

It's the McLaren name that has significence. Especially in the US, remember the Canam series whitewash?
Made and designed? Where are those turbo V8's from again?

Did the Ford part number for the starter change when they began equipping the cars with SS?
Also, Wifey's 24 VW Atlas has it and we both hate it. VW does disable it if you are running climate control which is good.

Ricardo congratulates McLaren on the reveal of the new W1 supercar

McLaren road cars are not the same as the F1 team. Engines are made in the UK by Ricardo.

I made that very clear.

Yes. 2023 cars and before used GR3Z11002A, post 2024 cars use PR3Z11002A (or B) depending on engine. Coincided with the Gen 4 Coyote which was designed for S/S from the outset (but not fitted on Job 1 cars in the US)

Don’t get me wrong, i’m not saying hybrids aren’t any good i’m just saying because you call it something different doesn’t automatically mean the ‘problem’ is resolved. For the most part the majority of hybrids aren’t true ‘hybrids’ but rather ‘dual powered’.

I've been riding round in my daughter's Sienna hybrid for about a week now and my SIL is not thrilled with it. No way the engine constantly on/off, on/off starting and stopping is good for it. Check out what Eric has to say about late model Prius problems on his YouTube: "I Do Cars". He has a very good channel, knows what he's doing, and is in a position to know.
