My old 2004 Opel 1.6, 105hp could deliver almost full load (car fully packed with passengers and baggage, with roof trunk also packed, going 140km/h uphill with fully open throttle, fuel usage was reported as 16L/100km, typical road usage was 8L/100km) for about half an hour without any problems.
Smaller engines are designed to operate at higher percentage of maximum capacity at lower speeds. Roll back to the days of 40hp engines and they max out highway speeds and can sustain that for hours. As you keep adding HP the maximum sustained load at a given speed doesn’t increase. So, 1000+ HP super cars can make use of that power at 200+ mph, but they don’t waste weight having radiators large enough to dissipate that heat continuously at 85mph because there’s no way the car is staying that slow while applying that much power.
External temperature also plays a role, cars need to be able to handle highway speeds at 45C adding headroom at lower temperatures. Trucks also need to be able to do that while towing a large load.
Also catalytic converters provide more complete combustion and thus generate even more heat.
In addition, I don't see why you wouldn't just buy a home battery pack and use that to store up energy. You can run the ice in the high power bursts to top off.
I just kind of like this post because there's going to be a lot of excess ICE engines out there once EVs take over the primary job of consumer transport.
Would be nice to have a DIY recipe to convert them over to leveling for your solar grid at home
Waste heat from an ICE must be way more useful than a simple 10 or 20° gradient that they're trying to use for house heating and cooling
What I mean - cars can do fine for long periods under load as long as they are cooled appropriately, not only for 10s of full power.
I literally stopped at the Ford dealer today; there, I told the sales lady trying to sell me on the F150 that, for a few more thousand dollars, I prefer the F250 because I don't want a dinky euroboost 2.7 L turbo V6.
Luckily the F250 has a 6.8L V8 base.
Basically sounds like your typical American that buys a massive car truck. Just a drive around suburbia with for no real practical reason and F-250 would be ridiculous for that.
I'm glad every American male feels compelled by Ford and GM's advertising to buy 70 and $80,000 trucks because we'll be that much easier for them to budget out for EVs when they start coming out
They sold very different cars in Europe than they did in the USA, but it was the same company.
