On this very PH forum we've talked about an American V8 engine for which, if it loses coolant, the ECU switches off the hottest cylinder in turn and can run for a long time with no coolant whatsoever

Why don't they fit this technology to F1 cars?

Becuase that would mean a loss in power whilst the engine temp drops again, it would never work in F1 as when you drop a cylinder you'll just have people flying past you down the straights.
The engine temps tend not be be much of a problem, it's just that its the first thing the commentaters seem to blame.....

There's probably a big difference in the tolerance for overheating between an ultralight highly stressed F1 engine with minimal coolant, and a slab of iron production engine putting out a couple of bhp per liter.

F1 cars are on the edge in terms of cooling capacity, designed to operate an ultra fine tolerances with the minimum of cooling capacity and designed into both the engine itself and the cooling system. You can quite often see that the cars aerodyamnic surfaces vary race to race around the rad exit chimneys and vents in order to keep the car at the point of greatest aerodynamic efficiency for a given cooling need.

Probably better to drop some power and lost a few places than to brop out with a blown engine though...

Somewhere like Monaco it wouldn't be a huge issue as power is less important than track position.

I'd expect a technical reg to prevent that kind of tinkering through the ECU though...

Such a feature might be very useful in the circumstance that Raikkonen found himself in last weekend: behind a safety car, travelling too slowly to cool the engine. In that situation a loss of power wouldn't have mattered.

Cooling, and to some extent heating (brakes/tyres), has always been an issues and congurations would often change race to race (or practice to practice) in the old days. Front radiators, side radiators, bigger/smaller, with or without ducts or blanking tape.

Even gearboxes can be prone to temperature variations.

Odd though that the Williams suffered when it did if it was simply overheating and likewise Kimi - why is it always him? Montoya was even further back in the queue so 3 cars with heat coming off them ahead. Or does the movement at any speed move so much aor that the temperature reduces and only the second car is likely to suffer poor cooling in a safety car situation?

Perhaps the Renaults have a 'Toast your tailgater' aero aid!

Yes, this is what I meant it for, for when the safety car is out, it seems ludicrous to break down at that time.
