You'd expect diesel engines to get smaller as time goes on, but recent reports claim GM's truck power plant could grow by more than a liter.
Rumored 'Big-Block' Duramax Diesel Could Be 8.3L and We’re Off the Rails Now::You'd expect diesel engines to get smaller as time goes on, but recent reports claim GM's truck power plant could grow by more than a liter.
California passed a law that new vehicle sales in that state, I think past January 2024, cannot be diesel if the engine is under 7 liters.
I wonder if this is Duramax's response.
Definitely not. Passenger cars will go EV relatively quickly, but you’re not going to see ICE go away in your lifetime.
Heavy duty trucks, aircraft, ships, etc all use petroleum combustion. That’s not going away any time soon. And as long as that’s still around they’ll still be making diesel.
You’ll end up seeing EV half ton and quarter ton pickups, potentially EV replacing the gas option in 2500+ trucks, but they’re going to have a diesel option for decades.
Quite a few big ships you could already kinda call hybrids, as they use diesel generators to run electric motors. One (slightly dodgy) source claimed 80% of worlds cargo ships, but it sounds just a bit too good to be true. But be the number whatever, each one could make use of solar, wind, or batteries to augment or even replace diesel. Or switch to something a bit better, like LNG in the meantime.
The specs for the Tesla Semi are also actually rather impressive, so who knows where that tech leads to in a decade or two.
Air is where they'll stay the longest, as batteries are simply way too heavy. Unless we invent some magical weightless battery made out of fluff and unicorn farts, there's very little chance of a viable electric passenger jet especially because unlike fuel which you use up, batteries are just as heavy when you land than when you started.
Holy shit I thought the 6.6 in my 2500 was huge, but imagine how much the block would weigh on an 8.3L. I mean at some point your front suspension gets absolutely crazy. Would be smart if they could make it a straight six though instead of a V8, way better balance characteristics and that’s why many of the big diesels have that layout.
