smaller than a V12 and more port area than a V8

Default Related: Why did all the F1 manufacturers go to a V10 (before it was mandated)?

I assume it has to do with packaging. Most of the power of a V12 but in a smaller size.

Default Had to do with the rules, actually. (more inside)

A couple teams and firms (Cosworth and Ferrari most notably) worked on changing their flat-twelve designs into flat-tens, but while the flat-tens didn't have the vibration problems of some V12's, they couldn't be tuned to run the same numbers due to the intake restrictions and the strange geometry of the furthest two cylinders in the flat-ten. Hence, the V10 became one of the alternatives, partly due to its design offering equal-length intake (though the Ferrari supposedly benefits from its unequal-length intake runs) possibilities alongside good vibration characteristics leading to better reliability. I think only Cosworth publicly admitted prototyping flat tens, though it's generally accepted in the motorsports community that Ferrari's experiment with the 180-degree architecture probably reached the prototype stage. A V10 offers the best power-to-weight ratio in some cases, but that really wasn't a strong enough argument for any of the teams since so much testing was needed for the change to ten cylinders... also, it's now pretty heavily disputed whether tens are really the best because of their other properties (vibration issues, balancing issues, etc.)

It's just a lot easier, for some obvious and some subtle reasons, to get a V12 to behave nicely than a V10... you can make a V10 seem quieter than it is with monster mufflers and the "cross kink" exhaust design (with nearly 90 degree bends toward the end of the exhaust system)... but that's a lot of plumbing to run under any car.

Ferrari has tried a lot of things, including the 408AWD being rumored to have been considered for production with a V10... but they're hard to make work.

The Audi/Lambo V10 gets around a lot of these problems in pretty interesting ways...

No more inside ;-) But if you are going to say that the rules require a V10, that is true but the V10 was used by most teams a couple of years before the rule mandated it.

Default Exactly - and some other things too...

Following the turbos, which were phased out, you could either go with an 8, 10, or 12. You had to consider fuel placement, plus another change that year was that the pedal box needed to be behind the front axle- so that shifted the driver back, making it already cramped.

Since Ferrari had never went smaller and turbo, and was still running a 12, most teams thought an 8 couldn't compete in horsepower. 12 was getting tight having to move the driver and fit in fuel, so 10 was the best packaging compromise.

IIRC only 2 or so teams went with an 8, most with a 10, and Ferrari and Lambo (which was powering a Lola) stuck with 12.

Even before that they found weight, fuel, and size benefits w/o giving up power

Default IIRC, it is not mandated by a rule, just happens to be the best package....

a 12 is too large and heavier, an 8 is smaller and produces less power. there are other factors in the rules as well that make the v-10 the best setup, but i dont think they ever made it a requirement.
