I haven't been able to find what the PHEV Clarity will do the quarter mile and 0-60 mph times anywhere on the web but someone here put a link on here last year where that information was. Does anyone have that link now? Thanks, Jim Stover

Thanks Leemell,
This was what I think the numbers were but just wanted to get the official link for it...nobody must really care about the Clarity PHEV performance when almost no one has done recorded tests on it on line.

I saw on a site although I don't remember which one it said nine seconds for 0-60. What I suspect accounts for the difference is if they are testing with a cold engine, i.e. they drove around in EV mode for the first part of their test drive, then they decided okay let's try 0-60, so they stomp the accelerator, the engine comes on but it is cold. I have a theory and also some experiential evidence that when you floor the accelerator pedal with a cold engine, when the engine comes on it only idles for the first few seconds, then after it starts warming up it starts to provide some minimal power to the generator, then eventually after warmup it provides full power. I am pretty sure I am seeing this but it's anecdotal and not based on any formal tests. But it also makes sense that they would not put a full load on a cold engine. This would certainly affect a 0-60 test especially if whoever is testing only does it once and doesn't repeat it. What I have been meaning to do is log 0-60 times with both a cold engine and with a warmed up engine. To be halfway scientific I need to do each test three times, i.e. three with cold and three with warm. Although I don't have any good places to safely to 0-60 so I may have to do just 0-50 but that should be a comparable test. If my theory is correct I will get better 0-50 times on a warm engine than a cold engine.

I did my first 0-50 test today, this was with a cold engine. Although cold being a relative term since it was 90 degrees outside. It took 7.6 seconds. Now that is probably at least 10% plus or minus since it's hard to stop the stopwatch at exactly 50 mph as I was only making brief glances at the speedometer, I think I actually stopped it at around 53 mph. But either way it does lean more towards having a higher number with a cold engine since the magazines are saying they did 0-60 in that same amount of time. Although to my surprise when the engine came on it was pretty loud, certainly not just idling, but no way to tell really how much power it might have been adding.

Any incline would of course affect the time but I think it was fairly flat, but that will wash out anyway as long as I do the hot engine tests at the exact same location. However I already know before I do any more tests I need to rig up a camera pointed at the dash because even though no cars were around I don't want to be driving with just one hand during hard acceleration, and also even though I wasn't looking at the stopwatch it is still distracting to keep glancing down at the speedometer. So I need to somehow get the stopwatch in the same shot as the speedometer, then start the stopwatch and have it already running when I do the 0-50 tests, then I can afterwards look at the video and simply subtract the starting time from the ending time. Not sure how soon I will get to that, so in the meantime I only have the one data point for whatever it is worth.

Anyone know what the 0-60 only on pure electric is like? I wish there was a setting where we can force the engine to not come on as I don't want the engine to come on just for a few seconds of passing power. Had my 2019 for almost a year now. I accidentally turned on the engine less than 5 times.

I saw an article that said 12.8 seconds in EV mode, as compared to 9.5 seconds in HV mode. Note sure what to make of that as the 9.5 seconds seems too high, that's the article that I was referring to that I wondered if they tested with a cold engine. Also I wondered how they came up with a number for EV 0-60 as it's nearly impossible to press the accelerator to maximum EV power without going over. Then I got to thinking about it, if you run the gas tank completely dry, but have a full battery charge, you could do 0-60 tests in EV only. Not that I am going to try it as it's generally not considered a good idea to run a gasoline engine dry, even though people say they have with their Clarity with no problems I'm still not going to do it. Although it would be kind of interesting.

As for avoiding accidentally turning on ICE, about all you can do is drive in Econ mode, that extends the gas pedal mapping so you really have to floor it to turn on ICE, plus in Econ mode the detent click position is where ICE usually comes on, so it's a little easier by feel to know when you are at the maximum for EV, at least if you can feel the detent and stop before you push past it.

Start with a full battery, put it in "sport" and DO NOT floor the pedal - just push it steadily, don't push past the detent and the ICE will not engage.
