Hybrid engine performance question

[fbov]

Here's something I hadn't thought about. ICEs get their peak torque and horsepower at a particular RPM. The peaks can be broad, and with lots of gears and smooth shifts, you can stay near there. But can the hybrid, with the eCVT, theoretically, be at peak torque or horsepower any time you want?

It can run at peak output, or at peak efficiency. This links to a good link.

Two things that may be relevant ...

For example, an electric motor can supply smooth torque at zero RPM. An ICE can only do that by slipping the clutch.

If someone knows, please jump in.

It you floor my Escape hybrid, you get moving with a burst of EV from the battery (EV mode), switching over to a far more powerful current, from the ICE driving the generator, to power to the traction motor (series mode) followed by a switch to ICE providing propulsion with an EV assist (parallel mode).

For normal driving I don't see power being a big issue for the Maverick Hybrid, but you won't win off the line if you want to drag race from stop light to stop light most likely. Just not the right vehicle for that kind of driving. It does seem odd to me that Ford doesn't give combination power data, Toyota doesn't seem to have any issue doing it with their vehicles. My 2008 Camry Hybrid get 140HP from the 2.5L 4 banger, and another 40HP from the hybrid system, and is rated to have combined power of 180HP and 199 foot pounds of torque. The hybrid system gives you plenty of get up and go for overtaking tucks on hills or level surfaces. Mind you the GVW is lower, and it has less drag being a car. You do notice a drop in power going up hills if you run the battery down though.

Ford does combine Hp ... the engine puts out 162 hp and motor of 29 hp for a combined of 191 hp.

Since the hybrid has max torque at 0 rpm, you should have pretty good acceleration when using the electric motor when merging or coming from a stop.

I can't speak for Fords 2.5 hybrid but our 2.0 hybrid Accord has plenty of get up and go when I hit the gas pedal.

The Accord has a different drive system where the electric motor drives the wheels and the engine locks in when more power is needed, so the Accord technically has no transmission.

IMO, its all relative. I rode motorcycles for years before I bought my first car, unless you give me a Ford GT, cars are slow.

I went to Brandon Ford yesterday; they had a silver XL [already sold], and it was the first Maverick I have seen. Locked up, though. I drove an Escape hybrid as I believe it has essentially the same power system as the Maverick hybrid; although 200 to 400 lbs lighter. That is a peppy little car... Not like my daily driver, which is a 2014 Focus ST turbo and six speed tranny; but good enough for passing and leaving stop lights at a decent speed. Do you guys expect about the same [or almost] pep from the Maverick as the Escape??? Thanks...

BTW, I went ahead and put an order in; Steve B told me it would probably be 6 to 12 months for delivery...

Very similar powertrains (Maverick upgraded), and weighs overlap...
Escape Hybrid: 3,554 lbs./3,706 lbs. (FWD/AWD)
Maverick Hybrid: 3674 lb.

However, I expect twice the load rating in the Maverick.

Some reviewers got 7.5 seconds 0-60 in the hybrid Maverick. That is as quick as most v6 SUVs.

For some reason I thought I saw somewhere the the gas motor was 155HP, but my memory could easily be playing tricks on me. If so, that's kind of a weak electric motor for the size of the vehicle, we shall see. I don't expect it to be as fast as a car, with more powerful electric motors. At the end of the day I went for a Maverick for the fuel economy, not for speed.

The electric motor is much more powerful than 29hp (IIRC it's like 120hp), the peak output combined is 191hp.

This is where I got my specs, says 162 for engine and 191 total so I assume the difference is the motor but could be figuring it wrong. 155 is the torque...​

 

[icegradner]

That's where I went wrong, I remembered the torque figures (its 155).

FWIW, MotorTrend was only .5 or .6 seconds slower 0-60 with the Hybrid, than with the EB2.0 in testing. Many mid-size SUVs of comparable size don't accelerate much quicker than the Maverick's tested 0-60 of 7.6 seconds. My current Outback (3.6 w/5EAT) tested at 7.1-7.5 seconds, depending upon the source, so its ball-park, probably with more torque off the line, verses needing the engine to get to 2k rpms before taking off.

Gut feeling, is off the line might be quicker, and then a bit slower during the last 5-10 mph on a 0-60 dash, assuming traction isn't a problem. (There's no spinning tires in an Outback on dry or damp pavement, driving all 4, all the time, the one thing I'll really miss).

Scroll down to the electric motor specs... 173 lb.-ft. from the traction motor moves you from a stop.

TFL just put a Maverick Hybrid against an original generation (4.0) Mazda/Ranger. In performing 0-60 runs, they clocked the Maverick Hybrid at 7.41......at a mile above sea-level. That was with both Nathan & Andre onboard, neither of which is a light weight.

There's a video on Youtube of the test, and they also pulled a near 2000 lb trailer, going from 30 up to the 60/65 speed limit, and were very impressed at how well the hybrid coped with the trailer.
