Resistance and restricted roll down hill

[Cmcbee]

Has anyone noticed a restricted roll when going down a steep grade? Similar to if you had shifted to “low”. I’m guessing that it’s the difference between a regular automatic trans and the CVT?

It's probably your regenerative braking. I'll bet there's a difference between normal and economy mode.

If OP tries the different modes they should see the difference. Also, hit the L button on the shifter dial for more regen. Really saves on brake pad wear going down hills or approaching a red light, while it increases battery charging.

And it's an eCVT, not a CVT. Huge difference.

When I first heard about the Maverick I liked everything about it except the CVT, didn't want that. Then, I read up a bit and found it was an eCVT. Very different. Clever and efficient.
I then ordered a Maverick pronto.

Same here. Mav is basically a taller Prius with bigger motor and a bed.

My experience is Fords are generally tighter on the downhill than other brands. The Saturn and my prior Dodge's were far looser going downhill.

That "restricted roll when going down a steep grade" is a positive for the hybrid as instead of wasting energy (and life of the brake pads) by using the brakes the energy is put back into the High Voltage battery.

I like that I can go down a steep grade without having the speed increase such that I have to apply the brakes.

Seeing other vehicles in front of me having to use their brakes which wastes both gas, as their ICE continue to run, while the brake pads heat up and wear down I am happy that my hybrid is keeping speed while putting energy back into the HV battery while the ICE engine is off saving gas and no wear on the brake pads.

This is just one of the many benefits of owning a hybrid.

That's the Grade Assist feature in action. See your manual and a video from Ford...

Also, it's an eCVT, not a CVT. It's mechanically nothing like a conventional CVT inside.

WHAT IS GRADE ASSIST

Provides additional grade braking with a combination of engine motoring and high-voltage battery charging to help maintain vehicle speed when descending a grade.

Worked in Fords research and development in Indianapolis for 28 years, I retired in 2008 so I got a heads up on anything that was coming in the future. Ford and Toyota co-developed the hybrid platform that they both use and that includes the ECVT. The transmission is basically bullet proof.

Doesn't it have something like 2/3 less moving parts than and old-school automatic transmission?

Slippery mode has the least resistance going down hill, ECO mode the most, at least on the Hybrid. Depending upon conditions, this might be a huge positive for the Hybrid, and the resistance decreases with any throttle input, even if the ICE hasn't kick on.

When I leave work, I hang the left at the light and immediately start a downward grade, and usually leave mine in Normal until I approach the next light at the bottom of the hill, and then switch to ECO allowing it to regen to the light, and leave it there for the balance of the drive home. - Also allows me to light accelerate up to the 45 mph speed limits, and keep in electric mode, since I'm going down hill. (ECO kicks on the ICE with less throttle input than Normal or Slippery modes do).

The eCVT, as most CVTs, have fewer moving parts than a conventional 6/8/10 speed automatic, but no band/chain as found in a typical CVT, making a more robust design. The eCVT uses a planetary gear set, as opposed to expanding cones.

Exactly. I love the feature since it keeps the Mav hybrid from rolling unnecessarily on our steep TN hills, the opposite of our F-150. And also love seeing the power gauge down in the green during those times.
