Basically, the 2.8l engine is no more, replaced by the 2.9l 4 cylinder engine. The 2.9l makes 185hp and 190 lb.-ft. of torque.

The new 3.7l inline 5 now makes 242hp and 242 lb. -ft. of torque.

The press release can be viewed here from The GM Source

That 4 cylinder is an awesome base engine. It makes as much power as the 4.3L V6 made (in 2wd form).

The extra power in the 3.5L will be nice. I still want to see a small block option.



Haven't these numbers been known for a while though?

Josh452

I believe the figures have been known, but it was now just made "official."

I like that the trucks will have more power than the Tacoma both in 4 cylinder and inline 5 cylinder offerings. 242hp with 242 torque sounds nice...but I still wonder what it will perform like in the H3 and H3x.

The 4.3L V6 made more or less power depending on drive config? My 2000 Silverado was a 4.3L V6 and was 2WD w/ 200hp 260tq. I doubt the 4-cyl feels as responsive off the line though it probably doesn't feel nearly as out of breath at higher revs, either.

I love how when high strung lacking in torque imports have impressive power numbers, everybody points out their lack of torque/low rpm power - nobody says 'yeah but it's more powerful and that's what matters'.

When GM comes out with a motor slightly more powerful than the Toyota equivalent but at a bit of a distadvantege down low - nobody really sees fit to mention that fact.



Say it's comparable to the Toyota V6 and I have no qualms. That would be accurate. The GM motor would likely do better at WOT, and the Toyota motor would likely do better during normal throttle driving and towing. Though neither is really worth mentioning since the difference is so minor. Again - that's why people bothering to mention the superiority of the GM V6 due to a few extra peak ponies seems a bit 'forced' to me, to say the least.

In the S10s there were a few different configurations. Probably had to do with catalytic converter size or some other feature that changed in 2wd vs 4wd. I seem to remember S10s getting the 200 hp rating for a while (like the full sizes), though I'm not positive about that. My dad's '98 ZR2 was 190 or 195 hp, I think. But around that time, if you got the 2wd truck, it was 185 hp and ~250 lb ft. Hell if I remember the specific years/combos that the ratings went with, but I remember a 185 rating on the 4.3 in some 2wd S10s.



Obviously, the 4.3 would kick its *** off the line. But the 4.3 is pretty much done playing around 4500 rpm, while the Atlas 4 and 5 cylinder engines will run rather eagerly right up to 6000 rpm without falling on their face.

I just remember when my friends rode in or drove my truck they said it seemed really powerful when just tooling around town because you could accelerate moderately without the trans ever bothering to rev past 2000-2200 rpm. It just accomplished a lot below that point. But it was deceiving because as soon as you floored it, it made all kinds of racket but didn't move all that much faster.

Chuck!

Too bad this didnt happen earlier when the H3 was introduced and got hit pretty good in the press for being too slow.

Threxx

I think even with the revised I5 it would just be a little less slow.

A vehicle that weight needs one heck of a powerful V6 or a basic V8. Period.

GM V6?

Anyway, Josh may just mean that it is good from a marketing standpoint to be able to advertise more power (since people buy horsepower these days). I suppose 242 hp looks better than the 240 (or 236?) made by the Toyota. I agree that I'd give the overall nod to the 4.0L V6 in terms of being just a bit more fitting for a truck (only down 6 peak hp, but up ~20-something lb-ft of peak torque). I think the 3.7L has a slight fuel economy advantage over the 4.0L, depending on the configuration, but I think both engines are more than adequate for a daily driven vehicle for most real world users.

The GM 2.9 has an advantage over the Toyota 2.7L though, unless it is changing for '07.

Very very nice numbers. And im confident that it has plenty of low-midrange power as well as all GM powerplants do.

GM is also consistant to release engines that are "chocked" down by some components or another so to say one of these engines might be 'forced' to produce a couple extra HP at peak to make a magazine rack happy is off base.

Threxx

Ah whatever you knew what I meant.

I will point out that the Toyota V6 is not available on the regular cab where as the GMT355's can have either motor with any cab configuration.

I had a dream last night that one of my friends got a slightly lifted white H3 truck, with mud tires. It was a diesel and sounded/looked awesome.

Edit: Wow, I just found out that they made a concept truck just like it, why haven't I seen it before!

The 3.7L I5 will be very competitive in the Colorado. I consider it now equal with Toyota. GM wins in HP and Fuel Economy, Toyota wins in torque (no replacement for displacement). The I5 is more powerful than Dodge and Fords V6. Nissans truck is about 500lbs. heavier thus making its HP advantage a non-issue. Nissans Frontier also get the same mileage as the full size Chevy Avalanche that has a 320HP V8 (15/20)

Chevrolet does have best in class 4cyl. power, too bad no one brags about 4cyls. in trucks.

I suspect people will still complain about the I5 just because it isn't a V6 even though it is putting out more power than up until 2005 any V6 truck ever did.

H3 just plain needs a V8 at its price.
