New 2023 Yukon At4 Order - 6.2L unavailable

I agree, the 5.3 engine is excellent)))) but not when it is compared with 6.2))) but here is a completely different story. By the way, in terms of fuel consumption, 6.2 is about the same as 5.3))) but 6 seconds to a hundred ... this is WOW))))

6 seconds quicker to 100? Or 0-100 in 6 seconds which is not happening. Fuel consumption may be similar, but the premium required has consistently costed $1/gal more here in WI.

The previous generation to the 5.3L was the Vortec 5.7L, which I'm very familiar with. 255hp. Never saw it as a sluggish engine until...my son brought home his 2016 Silverado a couple years ago. That 5.3L in comparison makes my 5.7L feel like Fred Flintstone's feet are pushing it lol. 355hp in that 5.3L of his I'm told. The 5.3L is a great little eight.

1hp per cubic inch has always been considered a very desirable benchmark for horsepower in an engine. That 5.3L exceeds that benchmark definitively.

That’s good to hear. Id rather have the 6.2, and would have if it was available, but sounds like the 5.3 will be just fine. Thanks for the insight.

probably was referring to 100km/hr.

Yes, the 6.2 engine accelerates 0-100 kmh in 6 seconds. While the 5,3 engine accelerates 0-100 in 8 seconds. This is a tangible difference. But personally, I prefer the way the 6.2 engine accelerates from 80 to 120 km/h on overtaking. Well, both of these engines need premium fuel

Yes, a mean 100km/h

5.3 uses regular, at least here in the States....

Off topic but, excellent helicopter in your avatar picture!

Big ass helicopter. MH-53E (SeaDragon), I flew those for the Navy among other helicopters.

If you put your foot into the 5.3L it has more then enough pickup, many have sold or traded from 6.2 to a 5.3 because of the fuel cost. there’s always a time and aplace where even a 6.2L is not enough power

That’s awesome! I work for Sikorsky and have built some of the newer K models (King Stallion). Great aircraft’s
