2009 H2 and H2 SUT - first production E85-capable Hummers

As our brothers at Autoblog like to say, it's "officially official." GM has confirmed their plans to offer all Hummers with biofuel-capable engine options. According to Automotive News, a Hummer official has said that the 2009 H2 and H2 SUT will be equipped with flex-fuel engines capable on running on gasoline or ethanol, making them the first such Hummers available. The 2010 Hummer H3 will be offered with a flex-fuel version of GM's direct injection 3.6L V-6 and we've heard plenty of rumblings regarding diesel Hummers too. Currently, the Hummer H3 is offered with a five-cylinder gasoline engine and a 5.3 liter small-block V8, both of which struggle to get fuel mileage in the mid-to-high teens. The H2 is available only with a larger 6.2 liter V8, which, as you can probably surmise, offers dismal fuel economy, and it would use even more fuel if it were running on ethanol. Emissions would probably be improved, but we're still talking about lots of fuel being burned here. We'll be on the lookout for more information on the biofuel capabilities of the Hummer brand, but we remain firmly in the bandaid-on-a-broken-arm camp on this particular announcement.

1. 9mpg on Ethanol and CAFE loophole for the win.

2. ==Emissions would probably be improved==

Nope.
Emissions would probably not be improved.
They are probably worse.

3. Wonderful, let's see how little fuel-mileage we can get! (as alluded to) The Race is on! Woooo!

They cant bring that diesel option soon enough it seems...*sigh*

4. The point of Lutz's recent comments to the effect that we should not be "going more complex" with hybrids, but instead "going simpler" with E85 are hereby revealed.

5. I don't know how ading the ability to run on alternate fuel can be bad, but I guess people just hate giving things a chance. what blows my mind is there is no mention of the HHR 2.2 and 2.4 E85 versions. which are to be the smallest and most fuel efficent ethanol engines availble to the US public.

but hey keep preeching the big oil retorethic about how ethanol stinks and we will wonder in 20 years why we are still behind the rest of the civilized world. we were ahead of most of the world with unleaded fuel and should remain ahead on fuel options.

I just don't understand why people want us to be FORCED into efficency.. it will come. the market will demand it. we are buying smaller cars now because we want them this is a wonderful time for efficency lovers. but being forced into it by government what can't we make our own decisions?

6. >> I just don't understand why people want us to be FORCED into efficency..

I think it's got something to do with the Antarctic Ice sheet sliding into the sea, china being now the third largest buyer of oil on world markets, the war in iraq, and the GM boondoggle of the 7x multiplier for ethanol. But that's just a guess.

7. @mike "GM boondoggle of the 7x multiplier for ethanol."

What is the 7 x multiplier? My google-fu is weak.

8. Don't blame me! I drive a VW Golf. It should be noted, however, that flex-fuel capabilty is expanding to small vehicles as well, such as the Impalla. Next year, I believe the Checy Malibu will also go flex-fuel.

And once more for the record, using E85 produces less emissions and greenhouse gases. Ethanol-haters play games with numbers and computer models. We test emissions from real FFVs, using real fuel. Debate ended.

9. Any E85 Hummer is now off the books for GM's CAFE numbers, that's the primary motivation. How many Hummer owners are really going to fill up with a fuel that reduces the already dismal fuel economy by 30%? Answer=0
