Didn't want to hi-jack that other post with this comment, but now that
GM has announced their 2014 Sierra/Sivlerado Pickup lineup with direct
injection named: "Ecotec 3"

Here are a couple links to GM's Marketing announcements
Basically the same info, just slight differences in the imagery

http://www.chevysilveradoweb.com/silverado/silverado-ecotec-3-engines.html

http://www.chevysilveradoweb.com/silverado/silverado-ecotec-3.html




More 'what is new' threads on EcoTech and note the contrary comments
that we also have here [emoticon]

New Silverado/Sierra Engines Leap Forward





This one a bit more tech, but only mildly techie and mention of boy
racer vs towing (again, just mention...scratches that surface). 11.1
compression and key to direct injection, but no mention of premium
just yet...even thought direct injection, there is fuel atomized in
there before the 'spark' event, so it can and most likely does 'ping'
Gen V Family Welcomes Three More Engines, Including A V6





MPG stuff and the marketing MPG race is on !

2014 Sierra V-8 Fuel Economy Tops Ford EcoBoost V-6

GM Tops Ford EcoBoost With More Efficient 5.3 L EcoTec3 Engine





This page shows the lineage of the EcoTech engines and note that they
have been in 'cars' for ages and mostly over seas
GM Family II engine





This page is mostly boy racer stuff, but does mention inclusion into
the pickup truck line up. Pushrod to boot ! I'm not totally sold
on alu blocks for towing heavy, yet...isn't the Texas Mile speed
record still held by that V10 baby Lambo at 250MPH? No matter, it's
yet another leap frog between them all...just fun to see my fav super
car's baby hold it (or held it) and key was UnderGround's direct
injection kit for that Baby Lambo

GM Releases Specs On New 2014 EcoTec3 V6 And V8 Engines




Happy reading and hope the 'other' badges don't spoil this thread too
soon. There is no right or wrong badge for EVERYONE, just individual
likes/dislikes

IMO the ECO is still the better overall motor. 1 mpg less, no biggie, but more HP and TQ and TQ at a much lower rpm, better for towing.
3.5 365hp @5000
420TQ @2500
340+TQ @2000-5000

5.3 355hp @5600
383TQ @4100
300TQ @2000-5600

I wonder if they will design any higher displacement turbo charged GDI engines to compete head on with the diesels. The higher torque capability and less complicated emission problems of gasoline powered engines might send the diesels to museums. Maybe the answer for towing will be a gasoline/diesel - the addition of some gasoline injected into the diesel engine might help out with emissions instead of wasting fuel and urea in the exhaust pipe.

Well, that might be interesting although I have no idea about the engineering or physics of that explosion. However, it would require TWO fuel tanks? One for gas one for oil ... sounds like fun.

How much more power do you want? They are already getting mid 3+ HP out of a V6! You want 400 HP? 500, 600? How much do you want?

A large displacement turbo engine will only burn more fuel. You want more power? You will have to pay for it at the pump!

Hardly. Unless and until the oil dilution problems are fixed,I wouldn't own a GDI engine on a bet.

500 would be nice! Our F150 makes (if I recall correctly) 410 HP. After awhile, its no longer fun. I would pay the premium at the pump for 500 HP. Heck, the car I am looking at purchasing this summer makes 662 HP from the factory. I say the more the merrier as long as they can keep temps under control.

400 ponies is good....I just want them all pulling at 1500 rpm.
