I am intrigued by this new 4.3 V6. I wonder what kind power it will be capable of 300+ hp?

 

Not sure I believe they are really going that route, but it had better be capable of 300+ hp (and mathematically it would be assuming similar specific output to, say, the new LT1), since that is where the Ram and F150 sit with their base V6s.

 

300+ hp should be a given. I'm more concerned about the torque. Hopefully this will also have 300+ ft-lb with good low end.

 

Ford 5.0 360/380 - DI 5.3 should be able to do this.
Ecoboost - 365/420
6.2 Ford - 411/434 (Raptor) 385/405 (Super Duty)

The new GM 6.2 should be competitve with the Ecoboost/Ford 6.2.

Remember that thee 450/450 is a preliminary number. I bet the Corvette comes in higher. The L92 DI test mule made 450 years ago. They have the potential to drop a 450/450 truck version on us.

Heck the current truck 6.2 makes 403/417 and is already competitive with the Ford Ecoboost/6.2

 

I'm expecting 350HP+ for the 5.3L V8.

What I'm real interested in is seeing what V6 comes with the new trucks.

 

Me too. With the expected weight savings and comparable power to the current 5.3L, this could become the popular choice. Do people really need closer to 400hp?

 

I'd be ok with a 300HP+ V6 in a 4x4 Crew Cab trucks.

I want to see if the Gen V V8 based V6 rumors are true, or if they use the DOHC 3.6L.

 

I suspect a 300+ hp V6 would end the need for the 4.8L base V8. My dad Silverado has the 4.8 and its an excellent engine. I don't understand why its not paired with the 6-speed though. If it had the 6-speed I am sure it would get a mpg or two better than the 5.3, seems a no brainer to me.

 

It's purpose was to be the cheap powertrain, not the fuel efficent one.

 

Found a couple artist renderings and based on the spy pics... I think these could be pretty close. IF this IS what the truck is going to look like... I may finally have a replacement for my '00 Z71. I love the sketches. Best looking GM truck since the 99-02's. Honestly, it looks like a nice Sierra refresh with a Chevy grill, which is kinda what I thought of when I saw all the spy photos, the cab greenhouse looks almost identical to the 07-12 trucks. I'm really glad to see a lower body line again. Truck sides have too much real estate to be one big curve the whole way down (current trucks).

 

Like to see a regular cab, short bed.

And yes, the character line at the bottom makes it look a lot better.
All trucks need one right there to break up the big expanse of sheet metal.

And while the greenhouse shape seems to be the same, it's not. The current truck has wrap-around door frames while the new one has inset door frames.

 

Saw these last week, and it looks better than I thuoght it would, though I think it is still fairly bland next to a Ram or even F-150.

That said, they looks decent here, but at least in the first (single color) sketch, I would guarantee the aggresiveness of the tires are waaaay overstated, and that really gives the pictures their beefy, meaty look in that sketch. That is going to be lost with real-world tires.

The 2nd (full color) picture has everything in better (more realistic) proportions, and is more what I expect as far as overall feel. Still looks better than I was thinking it would, but again, nothing that is making me say "oh, wow!".

 

The more I look at the sketches and rendering, the more I think it looks like the current Sierra.

 

That's why I said it looks like a "Sierra refresh" with a chevy grill. I've always thought the spy photos of the new truck looked a lot like how the sierra looks now. That could change when GM drops the cloth on the truck... it may look quite a bit different than the sketches.

I hadn't seen the photos in the link below until just now... there's a lot of camo missing on these! The writer even comments on how much it looks like the current truck:

I like the drawings a lot... if it looks like that... it looks like an 80 chevy pick up.... but modernized... i like it a lot.
