Be thankful for the Mav Hybrid Power

[710-oil-614]

I would have to disagree. You are saying the Mav Hybrid would be just as fast and climb hills just as easily if it had a 1 liter ICE?

I have explained in detail a few comments above how the two systems are fundamentally different and cannot be simply compared.

Putting a 2.5L Atkinson engine in the series hybrid system Honda uses with a fixed overdrive gear ratio for their ICE engine would not solve the problem with the CRV.

Reducing the power or size of the Atkinson engine in the parallel hybrid system FORD uses would have a significant impact on combined available power for the Maverick.

I never said it would totally solve the problem of the CRV, but you said ICE size "has nothing to do with it". Ford has put 2.0 L engines in their eCVT hybrids before. But there is a reason they went with a 2.5 L in the Mav. Better performance.

My wife had to get a new car recently, and wound up picking out a 2024 Honda Hybrid CRV, which up until this point I have been happy with. This past weekend we made a trip from PA through MD and WV on our way to KY. This drive features several climbs to 3000 ft above sea level with a speed limit of 70.

Let's just say I wish I had taken the Maverick as this little 4 cylinder, 149 HP engine in the CRV just handle the load. It was as if I was pulling a small trailer. Climbs at 70 was causing rages of 5000 to 7500 rpm. Ultimately, we decided to back off the speed to 60 to 65 on those hills.
Oh, and this wound up getting us only 34-35 MPG.

I've driven the Maverick on this same path, with a loaded bed and had none of these issues.

Should have bought her a Maverick, but she doesn't like it.

I just drove from Ohio to South Carolina in my XLT hybrid through OH, WV, VA, NC, and SC. Drove interstates the entire trip and got 36 mpg. Couldn't be happier.

I said the size has nothing to do with it in comparing the performance of the Maverick to the CRV because the systems are fundamentally different.

Until you understand and recognize the differences between a series hybrid system and a parallel hybrid system you won't get it.

Drive the Maverick next time and leave the wife home.

Not for performance. It's a variant of the Toyota 2.5 hybrid.

No, the engine in Ford Hybrids (not the eCVT) was jointly developed with Mazda when Ford owned a portion of them.

The CRV is also only rated for 1000 lbs towing. An indiction of how much excess power it has.

You don't understand much about it if you think tow rating is in anyway directly linked to power.

Right, the fact that an F-150 Lightning can tow 10,000 lbs. and a Cypertruck can tow 11,000 lbs. and a Silverado 1500 can tow 13,300 lbs., has nothing to do with how powerful their motors are. Give me a break.

I realize power is not the only factor in tow rating but usually it is one of the most significant ones.

There is no sense arguing with people that don't use logic.

I appreciate your insight (Honda joke) since you seem to understand this better than most; is the Ford hybrid system similar to the Toyota? I seem to recall (Ford joke) that the two systems share many ECTV characteristics if not some of the exact same parts. Before I ordered and waited 18 months (no joke) for my hybrid Maverick I studied up a bit in my low tech way on the undesirable, to me, cvt and was "sold" on the ECVT as reliable. Secondly why does my Maverick rev to the moon going down hill? In my low tech way I assume this is the recharge system "managing" overcharging by spinning the gas engine with electricity? Thanks again for the cogent thoughts.

Your original post made it seem that you believed power was all that mattered. Be clear next time.

HEY! We finally agree on something!!!

Ford and Toyota did develop some of their hybrid technologies together and have cross licensing agreements on that tech. The are both parallel hybrid systems that combine the power of the ICE engine and electric motor generator through the use of a second electric motor generator known as the eCVT.

Their systems are not identical and have many differences but at their core share the parallel set up and eCVT functionality that at least in the early stages (2010s) was jointly developed.

In regards to your engine revving going down hill. All modern vehicles don't use fuel when going down a steep enough grade which is why throwing it in neutral does not save any additional fuel and can only make it dangerous to stop or slow your vehicle.

As you suspect, because no fuel is being used the Maverick is revving the engine to recharge your HV battery. In your Maverick - it may still be diverting some power to your driveshaft via MG1 - it isn't using any fuel - and will largely be spinning MG1 to recharge the battery.

I've done my best to summarize the difference between Honda and Ford's (and Toyota) very different hybrid systems.

If you're a nerd and you like super dry content that is very well explained - this guy at Weber Auto (John Kelly) is pretty much the man for you.

Actually isn't that the Engine Brake mode where the battery is NOT desired to be recharged more on long downhills?
And so the tires spin the power motor to spin the Generator motor that spins the engine to bleed off the power not to be sent to the battery.

Wheels spinning in coast already recharge the battery normally, no need for engine to be spinning to accomplish that.
