engine speeds

motorcycles and past formula 1 engines achieved 14000 up to almost 20000 rpm. then why is the game locked to 12000 and even then the engines usually break?

This is a production car based tycoon game. One of the highest revving production cars I can spontaneously think of was the Honda Integra Mk3 with an 8,400 rpm redline. So 12,000 is sufficient. Measured in production car dimensions and the typical lifetime and running distance of an F1 engine these indeed break "immediately".

One engine revving higher is the Audi R8, 8700 rpm. Both v-8 and v-10 models.
Porsche GT3 RS 4.0 revs 9000 rpm.

Both well short of 12000 rpm.
Some road engines have been tuned/modified to rev up to 11000 rpm.

Only the T50 of Gordon Murray revs over 12000 rpm, 12100 is its redline.

And those basically are custom engines expected to go a few thousand miles between engine rebuilds, a life expectancy barely longer than a modern F1 or Le Mans Prototype engine.

And those old F1 engines that did the crazy high rpms? Scrap within 300 miles. Or less. And they were reliable when you remember that the old 80's turbos in qualifying tune could go bang within 4 laps. Modern F1 where they have to go 3k miles before they are scrap while still kicking out more power than the 80's turbos while using a quarter to a third of the fuel to go race distance are frankly astounding pieces of engineering.

Motorcycle engines end up needing more servicing and much more frequent engine rebuilds; even more so if you put them in a car because the demand on the engine to move a car is much greater than the demand needed to move a bike. And yeah, while 20k rpm motorcycle engines did exist in road legal trim, they only existed because of the highly graduated Japanese licensing restrictions that made the tech going into the 250s/400s that went that high as baby-superbikes to chase domestic market share; almost everything bigger stops at 16-18k rpm.

Fundamentally, Automation is about designing normal production cars, supercars and touring/GT cars at the peak. And 12k rpm is essentially 2-3k rpm more than these usage cases reasonably justify, and a 12k rpm is one of those nice extras like nitromethane or racing parts.

I have a car that revs 11500, 2.7 Liter V8 TT
