Thanks! I was not aware of it. It appears pervasive and ubiquitous, but completely slipped my radar. I'm barely a "hobbyist occasional track day racer" but it at least partially explains why I or anybody I know cannot come close to replicating the numbers I see (besides "they have much better drivers", of course:). First foot is HUGE, especially amongst different drivetrains (FWD/RWS/AWD, manual/DCT/AT/CVT), which handle the launch completely differently!

Without a rollout most 0-60 times would be useless. You make things like the surface the car is on matter way more than they should.

What's more of a problem is the opposite: if you increase the rollout so that the car's ECUs think it's being driven normally, and then mash the pedal to see how fast it goes, you get dramatically slower numbers: https://www.roadandtrack.com/car-culture/buying-maintenance/...

That reflects how fast a car will feel in daily driving as opposed to a drag strip

Thx; hilariously, I own both the Honda Odyssey and the Subaru WRX example cars from the article :)

>>"It’s that 5-to-60—the first number you should look at, and when the light turns green, the only one that matters. "

I think 0-60 from stop, 0-60 with foot rollout, and rolling start 5-60 are all valid and useful metrics, when explicitly indicated as such. While I've never participated in a public-street red-light drag race, I don't think 5-60 is a valid metric for it, precisely for the reasons it mentions - the 5-60 eliminates a lot of drivetrain and surface components which would impact the launch; and more directly compares just the pure power. My Subaru WRX has less power, but has AWD and grippy tires, will leave my 1-wheel-drive heavily-traction-controlled, all-season tires Minivan in the dust at launch (but things may become more equal from the rolling start or even on highway overtakes).

> more directly compares just the pure power

That's closer to what most people racing in a straight line want to measure as opposed to who can hook faster: hence drag racing using a two stage starting position

No metric will every reflect racing from a dig on a public street between the random surfaces, heat soak (it takes one or two pulls for most cars to start pulling timing stock), tires, etc... and I don't think any publication is really interested in satisfying that comparison.

[NikolaNovak]

I don't disagree. To your and authors point I have no interest in wrecking my daily driver transmission. I was just amused at the author spending 3 paragraphs explaining confounding factors that affect from-0 performance, and then offered the canonical from-0 situation, a red light, as suitable for 5-60 metric :-).

Anyhoo. Good read nonetheless :-)

No, that's a good thing, maybe that would force them to not fuck up their throttle response!

I think that particular quirk is just car companies trying to make slow speed driving easier by filtering inputs more.
