Interesting read, but how do you run a comparison test with so many vehicles, with the goal of finding the most efficient car, and not include the largest selling, and possibly most efficient electric cars out there?
It's not like it's hard to find someone with a Tesla.
But it sounds like this is automaker supplied vehicles, and as Tesla doesn't have a public facing marketing department, they wouldn't have sent a car.

Assuming the test exceeded the range of a typical PHEV battery, PHEV ratings if charged would be entirely dependent on the distance of the test. The longer the test, the closer the measure would be to their gas efficiency. The shorter, the closer it would be to their EV efficiency. You'd have "mpge = PercentICE*ICEEffiency + (1-PercentICE)*EVEfficiency and be trying to cram PercentICE, ICEEfficiency, and EVEfficiency into a single output number.Count this as another vote for "not charging the PHEVs is a bad decision."
Also, were there requirements that legs must be completed within a certain timeframe? If everyone is cruising along below the speed limit (for best efficiency), it tells us nothing about real world stats.
Since I'm not the only reader who wanted a comparison table ... I've slapped together this first-cut. It's based purely on the information in the article, so there are empty cells where the individual vehicle wasn't full described nor the body type apparent from the photo. (Body type may not be a useful attribute: it's intended as a proxy for weight class, and might correlate with MPG, but can't be fully analyzed without engine type and battery size.) The table is in the article's order; I have not sorted by make or MPG.

Makes zero sense. Why would anyone pay extra for a PHEV if they didn't intend to plug it in?PHEVs started each day with no battery charge.
Much like a pig, science is still incapable of preventing a Wrangler from rolling over.Getting a Jeep Wrangler above 25 mpg is a breathtaking technical achievement, proof that, with enough engineering and R&D budget, it is actually possible to affix lipstick to a pig.
Careful, too much horn-blowing will deplete the battery and cut into your driving range.This year, I took home the green jersey, becoming the event's first repeat winner and letting me blow my own horn just a bit.
ICE engines also lose efficiency under those conditions.Now repeat the test in the middle of winter to see how much efficiency the pure EV's lose.

I get your point about trying to measure something, and picking the ICE efficiency at the one you're more interested in.Why? Assuming the test exceeded the range of a typical PHEV battery, PHEV ratings if charged would be entirely dependent on the distance of the test. The longer the test, the closer the measure would be to their gas efficiency. The shorter, the closer it would be to their EV efficiency. You'd have "mpge = PercentICE*ICEEffiency + (1-PercentICE)*EVEfficiency) and be trying to cram PercentICE, ICEEfficiency, and EVEfficiency into a single output number.
Starting uncharged, at least the measured result would tell you something fairly accurate about the gas efficiency rather than "the gas efficiency is lower than this number and EV efficiency is higher than this number".
I got my EV in February, and summer driving is MAYBE a couple extra tenths of a mile per kilowatt better than winter levels. From watching the battery stats, in the cold the mileage starts noticeably low, but within ten minutes goes up to normal levels. In other words, the same thing as gas cars, so it's completely irrelevant.Now repeat the test in the middle of winter to see how much efficiency the pure EV's lose.
They wouldn't have sent a car anyway. They're in the middle of a lawsuit over having misrepresented the range of their vehicles. The last thing they want is more evidence against them.Interesting read, but how do you run a comparison test with so many vehicles, with the goal of finding the most efficient car, and not include the largest selling, and possibly most efficient electric cars out there?

For next year: Have all the BEVs start with an empty battery. They can't start until they charge. Score on both efficiency and charging time.I read the whole article but spent most of it hung up on the comment that none of the PHEVs were charged as a matter of fairness and to simulate long road trips.
I guess I can understand the long road trip part - if I’m in the middle of a long drive, I’d just gas and go. But, I’d also make sure that at the start of my trip (and at the start of each morning) I was fully charged and gassed - I’m not sure how forgoing that boosts fairness. On the surface, it seems to be the exact opposite.
The relative absence of US car makers is glaring.
Or try it in Nevada in August.Now repeat the test in the middle of winter to see how much efficiency the pure EV's lose.
I think that’s what surprises me most about the results. The numbers don’t feel impressive or substantial. They are especially worrisome for the SUV type vehicles.I have to say, this really highlighted how bad the SUV craze has been for wallets and the environment. I was not expecting so many hybrids to have worse mileage or barely beat the car we bought 20 years ago. It's better than an ICE drivetrain, of course, but that's like 4 decades of efficiency improvements cancelled out for aesthetic reasons.
Also most miles are commute, not roadtrip,I read the whole article but spent most of it hung up on the comment that none of the PHEVs were charged as a matter of fairness and to simulate long road trips.

Shouldn’t that be ”increased” not “dropped”?Tucson faired worst in the uphill climb sections where fuel economy dipped to 24 mpg (9.7 L/100 km), a figure more in line with the bigger SUVs. On flat ground, it dropped to around 47 mpg (5 L/100 km).
