Dyno numbers for Hybrid Maverick?

[mamboman777]

Could someone please strap a hybrid Maverick to a Dyno and post results?

I want to know:

It's 191 hp accurate?

Is the torque only 155? Or did the system provide more overall? If so, what's that number?

If you are the one to get this done you're a hero.

Great idea! So I just clicked "Watch this thread".

While peak HP would be interesting to know for passing on 2-lane highways, etc, what I'm really interested in is the TQ curve. From the 0-60MPH times stated by C&D and MotorTrend I imagine the battery side of the drivetrain adds TQ beyond the 155lbs stated.

And since conventional ICE drivetrains suffer some parasitic loss in overall numbers on a dyno, I'd also be interested in if the eCVT reduces the normal loss or ??? But I don't know how that would be calculated.

I'm a Hybrid engine/eCVT neophyte so the above questions are based on my ICE background.

Who can we convince up do this? Who has access to a Dyno and a hybrid Maverick?

Would be interesting to see the real torque figures, 155fp seems rather low given hp of the electric motor.

Exactly.

Exactly.

I was kind of shocked by the low number my 08 Camry Hybrid with a 140HP ICE and 40HP electric drive is rated to 199fp of torque. The only thing I can think of is that Ford kept the torque down to improve city fuel economy by lengthening how long the system can run on the battery.

The 155 ft-lb. is the ICE. The traction motor is more like 175 ft-lb. from 0 RPM (current limited).

However, given the ICE needs to run at high power to generate the current that drives the traction motor to these levels, you need the lower number to achieve the higher. The HVB DC-AC converter in a hybrid doesn't have the capacity to provide more than ~1/3 of it.

And yes, it would be very interesting to see a dyno report, both a fast sweep, a la 0-60, and a slow sweep, to see steady-state output. I expect the two will differ substantially.
