2014 Chevy/GMC specs

[timswi]

Do I hate GM? YES. But for the bailout, what they did to my wallet, and the company I work for. NOT THE PRODUCT. Although I feal they are on the low end when it comes to trucks. My opinion.



The problem here is this engine only puts them on par with the competition from 2011 or so. They are taking the conservative approach as usual and playing catchup when they had a chance to be innovate and a leader.

Ok...You've made your loathing of GM abundantly clear over the last 4+ years and I think everyone is very aware of your position on the matter..Time to let it go..It's worn out it's welcome to be honest.

That being said..What's wrong with the updated 5.3?...Gets the same or better mileage with a relatively simple normally aspirated V8 as opposed to multi turbos on a V6 to accomplish the same thing....A 400+ HP Corvette can easily get mid 20's, however a similar drivetrain in a 5000# truck can't produce the same results at this point...The GM powerplants are fuel efficient on their own, it the brick aerodynamics and sheer weight or the trucks hold them back, same problem that everyone has...With an aluminum frame, 2:73 gears, a sloped front end and no 4wd along with a 500# tow capacity could easily produce mid to high 20'sMPG...No one would buy it as it would be useless.

What innovative drive train were you expecting?...GM sticks with what works...Not what infatuates people..Ergo the 350ci that is still the most popular motor ever built....Improve what works, don't keep throwing things at the wall hoping something will work..That's not innovation.

I didn't buy my truck for MPG anyway...I'll take the average 16mpg with 403HP that I get.

Here's the dyno graphs for comparison. While the EcoBoost delivers down low, the other Ford engines do not. The new GM 5.3 has a much broader torque curve than any of them.

It's actually called DuraLife and it's made by GM (not somebody else). Their Engineers developed the process:

GM Creates Recipe for Brakes That Shine

“So doubling the average life expectancy of the brake rotors from 40,000 to 80,000 miles is something we think our customers will appreciate.”

I got 90,000 miles out of my rotors on my 2004 Z71 before I had to turn them and replace the brake pads. I would be pissed off if my rotors didn't last past 40,000 miles. The only excuse I could see for that is if I were towing at maximum load for 40,000 miles. Shoot, the drum brakes on my '95 Toyota lasted 139,000 miles and when I sold the truck they were still good to go!

40k for a set or rotors, I'm sorry but that's terrible. Even 80k is garbage. I replaced the rotors on my Tundra simply because I wanted to put new calipers, pads, and rotors at 130k. I think the first set of pads lasted almost 100k.

These are all new engines. They share nothing with their predecessors other than displacement.

Single cam pushrod?

Single cam pushrod?

Probably the whole short block.

 

[Peacock]

Single cam pushrod?

Yes they are.

They share no parts with the old engines. Just about as all new as can be.

 

[94BULLITT]

They are calling it a Gen 5 small block. It still looks a lot like a LS motor.

Yep. Similar but different.

To some here, no matter what GM does it's dismissed out of hand but everything Ford does is perfect and to be worshipped...That's pretty much why I really don't pay much attention to this thread anymore...It's a relentless anti-GM diatribe on every subject. It has grown beyond tiresome.

Boy, ain't that the truth...

I'll be the first to admit that I'm a GM guy. But I've driven friends' Fords...and just haven't been impressed. LOVED my 2001 GMC Sierra though...I prefer the nose of the GMC over the Chevy. I *thought* they said there would be more differentiation from the brands, but I haven't really seen it...yet.

Since I'm new, I just have to give you ford drivers some grief...FORD = Fix or Repair Daily, Found On Roadside Dead, For Only Retarded Drivers, Driver Returning On Foot (backwards)...I've never heard of any of these analogies for Chevy!

I'm an admitted GM guy too..(My dad said he would pay my car insurance until I graduated from college as long as I was driving a GM--He meant it)...I also have in-laws that have Dodges and Fords..I have nothing against the other brands, they just aren't my thing and the reliability and durability of my GM's have never given me a reason to change.

I don't bash other brands like some here like to do...They all have their place and purpose..To each his own..I don't denigrate other individuals vehicle choices....I'll reserve some space for "Smart" Cars though.
