when will we see the 5.3 in the Colorado/Canyon?

Let's hope never.

Let's hope never.

This, because consumers hate having more options.

Will it be worth it? You're looking at a significant weight gain to get 50 or so more HP. Yes, the truck would feel quicker with the added torque but the 3.6 isn't lacking in power and is fairly well matched to the size of the Colorado.

It is likely that. A 5.3 would weigh barely more than a 3.6, with the weight being higher due to dohc heads, while the 5.3 is far. More compact and perhaps 50-75 pounds more. For the performance improvement and slight increase in weight, give me the V8 every time!!!

The 5.3L is aluminum, which helps it's cause and makes more power and torque...what would be there not to like but the fuel mileage.

Dodge/Chrysler engineers a 700+ hp engine that goes in a limited amount of cars, where GM can't put an engine - that they'll build millions of that is a truck engine - in one of their trucks that they plan selling 1/3 of a million in a single year. I'd say that they'd throw the fans a bone, but judging by their full size trucks, it ain't going to happen.

I'm hoping to see a 5.3 Denali. I'll settle for a 2.8td Denali though.

That's EXACTLY what I was thinking.
Not holding my breath for a 5.3L but a 2.8 Dmax Denali I could easily see coming to market and doing really well. Provided the little D-max performs well. Good throttle response will be paramount. If it has a lot of the dreaded turbo lag that many small turbo motors are known for, I will have to pass on it, but in concept it sounds like a really cool truck.

You've got the only diesel engine in the class on its way along with a pair of very good gasoline engines. After driving the 3.6L in a Canyon recently, it was plainly obvious that there's no point in offering the 5.3L boat anchor with that piss poor AFM technology with an astounding level of suckage that I know too well.

Unless the diesel turns out to be an unreliable dud, consumers will have a trio of great engines to choose from. I think they'd be made even better with an 8 speed automatic.
