In a Maverick, that's the sound of your foot lifting. If so, you have descended a very long hill, filled the HVB, and moved to engine braking, Hill Assist's last resort for staying off the friction brakes driving down hill. Very loud, and only heard after descending a very long hill using Hill...

Yes, all the way to the bottom of the hill. At least 5 miles, maybe 10 or more, and that starting with ~50% charge. It's really hard to crest a hill with a full HVB. You typically bleed off the HVB climbing the hill. A hybrid's battery is an energy buffer, not a source. This question is moot.

Based on C-Max and Escape Hybrids... - top speed is limited by the redline of the traction motor. I've seen 110 mph for Maverick, 125 mph for Escape. Could be a gearing difference (redline limited) or just reflect a difference in aero drag. - top speed for EV is 85 mph, due to lubrication. The...

I've found the ICE runs about 10% of the time to keep up with air conditioning, which is 100% HVB-powered. Heat is 100% ICE, so you might find a higher duty cycle is required to keep you warm. Sleeping in a running vehicle has it's own issues.

You know the Maverick's 2.5L Atkinson will only use 90% of that 13:1 compression ratio? 13:1 is a geometric calculation that ignores Atkinson's reduced intake volume. I agree you'd need premium, in a motorcycle because it's a conventional engine. Not so much at the Atkinson's actual ratio of...

Glad you're enjoying the car! Cars with motors are more like computers; they have an on/off switch, but you don't get to use it. You tell the car to shutdown, and then sit back and allow it to shut down. That can take a long time. I think Ford designs for a degree of anticipation ("on" before...

If that's all it was, I'd agree. In this case, there is a new standard as of May 2020, ILSAC GF-6B, that applies only to 0W16 oil. Our cars are designed to work with GF-6A oil. I'm no oil formulation expert, but I do know standards don't change without a reason.

Most points already covered (starting, emissions, gelling, DPF). This is not a new question. Here's the usual application that favors diesel-electric hybrids. Nice steady loads, no start-stop, no gelling concerns... emissions are another story.

The C-Max did that, when Hill Assist was enabled. Quite loud. The Escape switches to a resistive load (drops to 20kW once HVB is full). I expect the HF45+ will follow the Escape design. Liquid cooling makes a difference.

No. In my Escape Hybrid, MTE is very dependent on the last few miles driven. I've had tanks claim they'd last 750+ miles, because I filled them after a 30-mile, down hill trip. That overly optimistic forecast is quickly corrected....

Cold start behavior of my HF45 Escape (and the HF35 C-Max) depends on several things. - Very low HVB charge level will bring the ICE on right away. - Low ambient temperature will bring ICE on right away, espeically if you have the heat turned on. - Once moving, high HVB charge will let you EV a...

That they are!

My AWD Escape came with Bridgestone Ecopias. They proved far better in snow than expected. Glad to see other Ford OEM tires work well in the white stuff.

Yep. The car has the same 12v features as any car, so it has to sense a fob approaching if it's going to respond to you grabbing the door handle. The clicking you hear when you pull on the door handle is the HVB contacts charging up and closing. There's a lot going on for a moment, then the...

PowerBoost is a "torque converter replacement" hybrid. An electric motor is placed between the engine and transmission, where you'd normally find a lock-up TC. It's a conventional drivetrain with a novel advancement to the lock-up torque converter. Conventional engine, conventional transmission...

I think you've got the right idea. This hybrid high-voltage battery is an energy buffer, not an energy source. The HVB allows the control system to add load to the ICE when it runs a part throttle, so it's both more efficient when it does run, and stores energy for the low throttle load...

You can get good snows that won't hurt mileage. I used Michelin X-Ice 3 on the C-Max, and all I saw was an extension of the prior Summer's trend.

Exactly, they change color when you change the light source. Under one light source, two samples are the same color. Under a different light source, the two sample are different colors. Spectral characteristics of light source, sample and detector are all equally significant to perception.

Let's be fair. Benson tests tires, so he pitted one of the best snow tires from his snow tire test, against one of the best all-weather, snow-rated tires from his "all-season/all-weather" test. He's done lots of combinations of tires, snow and FWD/AWD/RWD.

Yep, but the motor redline is good for about 120 mph in the Escape Hybrid, which has the same gearing and tires.
