All Prii use the 2-motor TRW power split system. Can't same about Avalon hybrid, but I'd expect it's the same. Excellent videos here. This makes sense, and for EcoBoost as well. Both engine designs modify the intake charge volume, so they can compensate for reduced ambient air pressure.

This is also a strength of the HF45 drivetrain, so expect the hybrid 50-70 to be no more than a small fraction of a second behind the turbo (if that).

To those adding weight to the bed, I suggest looking into the vehicle's weight balance first, so you know where you are starting. You may find that a substantial front weight bias (common in unloaded pick-ups) that would benefit from a different placement. Remember that you have 1-wheel drive...

Just a thought... put some winter tires on the 17's and get new wheels/tires as a matched pair, so you maximize the larger tires' capability. You do live in Colorado, and AT tires are not the same as snow tires.

My wife did the same 10 years ago, our first FWD in 30 years. First car that never saw snow tires, too, but we always had a car with snows, if needed. And that may be the best reason to get snows on steelies for one of the vehicles, just in case. I like to look at whatever reviews I can find...

I use Dick Turner's suggestion to pretend there's an egg on top of each pedal. See if she can stop making scrambled eggs. Absolutely true. I see RR as the "distance penalty" and drag as the "time penalty." https://www.fueleconomy.gov/feg/fe_test_schedules.shtml City Highway High Speed A/C...

OP asked aout hybrid modifications. Only half jokingly, @MysticRob suggested gutting the vehicle for weight savings because it helped an early-model Insight. I responded why weight savings no longer matter (bigger motors allow functional regen braking) You read things between the lines that...

If you stomp on the HF45... - the HVB output jumps to 35-40kW as the ICE starts and speeds up. (0- a couple mph) - HVB output drops to 0 as the ICE is generating current for the traction motor. (up to ~40 mph) - HVB output rises again as ICE switches to direct drive with battery-based EV assist...

I tried to find a description of the hybrid technology in the 2019 Accord, to avail. I know the new CR-V has a unique hybrid drivetrain layout, but my understanding is it's new. Do you have anything? I've tracked the "dash" mileage against what the gas pump says. I see the dash reading 5% high...

You missed one... the Accord is 20% smaller in cross-sectional area than the Maverick, so Accord is inherently 20% lower drag. That's the one Ford can't overcome with a larger, more capable vehicle. I'll argue that the engine size matters less than engine efficiency, a smaller, liquid-cooled...

Have you tried "L?" You're assuming the user empties the HVB every day. In actual use, you only need charging capacity to replace what you use. That should make the charging discussion more palatable. (Charging and range are why I'm in a hybrid.) If the recent model, you were looking at a...

Expect your owners' manual to say the same thing. I would suggest a maintenance charger for the 12v, too.

No engine braking in my Escape. The C-Max Hill Assist defaulted to engine braking after it filled the HVB. Very loud... The Escape Hybrid switches to a lower-power regen mode, perhaps using a resistive load, and remains silent. In terms of off-throttle behavior, regen braking is calibrated to...

Seriously?? This is your authority? " I have a background in math, but I'm no expert in engineering or physics. ..." Algebra errors in the first equation, and the second reduces to accel = torque / mass (F=ma). He's at least honest enough to admit there are limits to his understanding...

For the record: C-Max was introduced in the US in late 2012 as a 2013 model. I had an October 2012 build. All Ford Escape hybrids (introduced in 2005) use Atkinson-cycle engines. This is not a bad video (no sound, right?) but as with nearly all YouTube videos, there's a kicker; he's...

You said it, I didn't. Please take your own advice.

I see off-throttle regen braking of about 0.2x my speed, doubling to 0.4x in ECO mode.

Two can play this game, something I'll do once. You should have listened at min. 4:05: "So, for maximum acceleration of the car at any snapshot in time, we need to maximize the torque at the driving wheels." As someone said, F=ma, all day, every day. He starts into the weeds at min. 8:18...

Please consult an actual authority, like Sears & Zemansky. F=ma all day, every day.

True, but I have seen cars roll on the highway when they did a quick maneuver and the tire came off the bead. Thankfully, it was in my rearview mirror. I remember diagrams like this from my youth, when bias-ply tires were the standard, and this kind of thing was critical to making 20K miles on...
