Our friend Mike Levine, proprietor of PickupTruck.com, was trying out the new H3T pickup out in Moab, Utah this week and learned that the H3 will finally lose its hoary old five-cylinder base engine in favor of something a little more modern. A new flex fuel-capable direct-injected 3.6L V6 like the one used in the HX concept will become the new base powerplant for the H3 by 2010. The last remaining question is, will the H3 get a diesel? The answer is yes... eventually. We spoke with HUMMER's Martin Walsh at the New York Auto Show this week and a diesel is in the cards for the H3, and it will be different than the diesel six-cylinder being used in Europe. Since the 4.5L fits in anything that GM's small-block V8 does, the European diesel six is possible, but a smaller diesel seems more likely. To that end, we've heard rumors since last spring of a new diesel V6 being developed for use in the H3. We don't know when it's ultimately going to arrive, but it will, and change is clearly afoot on the powertrain side at HUMMER.

While assorted activists, politicians and random individuals carry on about the spectres of global warming, imported oil, CO₂ emissions and other issues that combine to create timetable-free doomsday scenarios, there are people working on potential solutions that do not involve us driving around four-wheeled Segway scooters. That's right: the "dreaded" internal combustion engine might yet provide the answer -- or at least an answer. And because Lotus is the entity searching for the answer in this particular case, the end result might not only be green -- it looks ridiculously fun, too.

The car you see here is the Geneva-bound Lotus Exige 270E Tri-Fuel concept, the successor to 2006's Exige 265E, which made 265 horses running on E85. The 270E goes a step further. Not only can it run on gasoline or ethanol, it achieves its peak output -- 270 horsepower and 184 lb-ft -- on methanol, hence the Tri-Fuel label. Incidentally, that power figure is the highest yet for an Exige coming out of Hethel. Even more interesting, however, is Lotus' research into producing carbon-neutral synthetic methanol. You can read about it in detail after the jump, but in summary, the process involves using atmospheric CO₂ and reacting it with hydrogen created via renewable electrical power to create methanol. Liquid methanol could be transported and distributed much in the same way gasoline is now, making for a feasible infrastructure if the idea were to take hold somewhere down the line.

Lotus is also hunting for solutions involving EVs, as well as optimizing the traditional gasoline-powered ICE through its Hybrid and Electric Vehicle Group. One must admit, however, that the idea of a sustainable, synthetic, carbon-neutral fuel driving internal combustion engines with the same levels of power we currently enjoy is the equivalent of having your cake and eating it. Press on, Lotus.

Jon Markman at MSN Money doesn't hold back when he says "Corn-based ethanol production is sure to go down as one of the greatest mistakes ever in U.S. energy policy." It's even more provoking when he writes "replacing fossil fuels with corn-based ethanol would double greenhouse gas emissions over the next three decades. The studies show that switchgrass, an alternative to ethanol that's more weed than plant, would boost emissions by 50%."

The problem isn't with the cars, the problem is with what it takes to grow the biofuel in the first place. Clearing the land, harvesting, and refining the crops, plus the loss of forest and wild lands and habitats, amounts to creating a carbon footprint worse than fossil fuels. According to the Science article which, admittedly, posits an extreme scenario, it would take 423 years to even out the carbon debt if Indonesia's peat lands were converted to palm oil fields.

The research is starting to give some people pause, such as the folks at the European Union who declared they wanted ten-percent of the block's transport fuel to come from plants. And Joe Fargione of the U.S. Nature Conservancy asks, "Is it worth it? ...[S]urprisingly the answer is 'no'. These natural areas store a lot of carbon, so converting them to crops results in tons of carbon emitted into the atmosphere."

Thanks for the tip, Zo!

In the fuel economy and future tech debate, the hybrid vs. diesel vs. hydrogen fuel cells vs. smaller cars and smaller engines always provokes a fair bit of discussion among Autoblog commentators. At this point, no one yet knows what's going to win since nobody knows how the volatile mix of products, timelines, prices, regulations, legislation, state standards, and gas prices will ultimately pan out. Bob Lutz's prediction is that diesels, at least as far as the US is concerned, won't be much of a factor.

His reasoning is simple: "I think customers are going to say, 'Wait a minute. At equal fuel prices I'm paying $4,000 more for this." Unlike many countries in Europe, the US offers no incentive for people to buy diesels. In the States the price of a diesel vehicle is often more than $1,000 higher than that of a gasoline-engined car, and diesel fuel is just as expensive as gas (throughout California and other states, it's slightly more expensive than premium unleaded). In that case, Lutz's opinion is that just about all the customer will glean from an oilburner is a higher car payment.

Lutz sees diesel uptake in the US hovering at about eight-percent. The technology he sees as winning the day: ethanol. It's clean, it's easy to integrate into the refueling infrastructure, and it "doesn't require a change in consumer behavior." (Except for the people in emerging markets who've seen the price of corn skyrocket.) For another take on the fuel economy battle, according to Kelly Blue Book, 40-percent of US new car shoppers think hybrids are the future, with just 17-percent citing flex-fuel.

THE BREAKTHROUGH WE'VE BEEN WAITING FOR?

There seems to be an anti-ethanol bias in so much of the media that GM's recent announcement didn't get the kind of coverage it deserves. Did you miss it, too? Here's the news: GM is teaming up with a company called Coskata that's come up with a breakthrough to make cellulosic ethanol.

But there's a big difference between their effort and everyone else's. Coskata's process goes way beyond using switch grass. It can use any kind of agricultural waste. Even more importantly, it can use a lot of municipal waste, i.e., most the stuff we're dumping into landfills. In fact, it can use anything that has carbon in it, including used tires.

Move over Brazil! We're about to get into the ethanol game in a big way.

Switching a racing series to ethanol? Smart. Shipping the ethanol around the world to show how green that racing series is? Less so.

A1GP has announced that its upcoming race in New Zealand will mark the inauguration of the series' switch to E30 Hiperflo ethanol-gasoline blend, which, as organizers point out, cuts CO2 emissions by 21% and, of course, reduces the use of fossil fuels. The mixture is specially made for use in A1GP and consists of 30% ethanol and 70% gasoline. While IndyCars and Champ Cars have run on methanol since the '60s, both series are based in the US and have to ship their fuel to fewer races abroad than A1GP.

Logistical considerations aside, overall we say it's a good thing that motorsports are shifting to more sustainable and environmentally-friendly fuel sources. At the 2008 Detroit Auto Show this week we heard all about the American Le Mans Series and its green intentions. Ferrari, which is set to begin supplying the engines for A1GP in two years, revealed its bio-ethanol-powered 430 Spider in Detroit, as well. Meanwhile, the FIA has revealed a preliminary timeline for introducing a new F1 engine formula that's anticipated to include environmental measures.

Ferrari's press conference here in Detroit was rather short and to the point. They reminded us that Kimi is World Champion and that the team is busy readying his defense. They also pointed out that the F430 GT is doing a bang-up job in GT2. And then they talked about the street cars. Besides telling us that Ferrari had a record year, with sales up 8% to 6,400 units worldwide, they also showed the E85 ethanol-powered version of the F430 Spider we talked about yesterday. The F430 Spider Bio Fuel runs on the familiar mix of 85% natural ethanol and 15% gasoline, which results in a modest 10HP power bump and fuel economy that improves by 5% over the standard gas-only V8. So that means that the sweet-sounding 4.3-liter plant is now good for a true 500 HP.

The bio fuel car on display in Detroit is still labeled a concept, but the company says that it'd like to put it into production as part of its efforts to reduce fuel consumption and cut emissions 40% by 2012. As we mentioned yesterday, the regions where ethanol is readily available – like the Midwest states, Brazil and Sweden – are not major markets for the sportscar maker. But ethanol is already being used in the ALMS and elsewhere, so Ferrari already has some experience with it. We already put in our request to have one in the AB Garage. We'll let you know how that goes.

Robert Zubrin thinks so. Zubrin is an aerospace engineer and long-time advocate of manned missions to Mars. While going to Mars is a highly dubious proposition given the issues we need to deal with on our planet right now, making all gasoline engines flex-fuel capable as Zubrin promotes in his new book is probably a very good idea. The incremental cost of flex-fuel capability is only about $100 per vehicle and that would provide the ability to use any alcohol fuel including methanol and butanol. The corn ethanol that we use today will make little if any dent in our oil imports.

Cellulosic ethanol, methanol and butanol do hold a lot of promise, though. Glenn Reynolds of Instapundit and his wife, Helen Smith, have an interesting interview with Zubrin on their podcast that's worth a listen. Some of Zubrin's arguments for using alcohol fuels are a bit over simplistic and ignore some of the pitfalls associated with them. That includes draining fields of nutrients if all the leftover material is converted to fuel. Alcohol fuels are unlikely to free us from oil dependence on their own, although they can make a dent. What they can really do is help diversify energy supplies and domestically produced fuels can also help to fund research into other renewable energy sources. What we really need to do, however, is find different ways to reduce our total consumption of energy while maintaining our current lifestyles. Let the flames begin!

Taking a short break from wrangling the new HHR SS around the track at the Bondurant School for High Performance Driving (see above -- that's me), we got a chance to speak with some of the engineers behind the SS series of vehicles, among others. We took that opportunity to ask whether or not GM has considered using the alcohol-based E85 fuel as a high performance option -- as opposed to just marketing E85 as a "green" fuel. Perhaps not too surprisingly, the idea has been considered at General Motors. E85 happens to have a very high octane rating. The fuel burns at a comparatively low temperature, meaning that additional power can be extracted from a given amount as compared to gasoline. Turbocharged vehicles offer an excellent opportunity to tap into that additional available power, so the fact that it was left off the HHR SS probably means that we're not likely to see that angle of the corny-fuel any time soon.

General Motors' Opel division will use the IAA in Frankfurt to push its ecoFLEX initiative, which will see the automaker leverage multiple technologies to help lower its offerings' CO2 emissions and fuel consumption. Headlining ecoFLEX for the automaker is the Opel Corsa Hybrid Concept, which mates a 1.3L diesel with the next-gen Belt Alternator Starter (BAS) light hybrid system (BAS is the mild hybrid setup used in the Saturn Green Line vehicles), which trades in the current system's NiMH battery for a lithium-ion unit. The arrangement is good for a claimed fuel economy rating of 62.7 mpg (3.75 L/100km). It also emits just 99 g/km of CO2 per km.

Joining the Hybrid Concept in Frankfurt is the Corsa 1.3 CDTI ecoFLEX, which has 75 hp, boasts fuel economy of 52 mpg and CO2 emissions of 119 g/km. In addition, Opel will showcase CNG-powered vehicles, promote its "Eco-Turbo" approach to using smaller turbocharged engines that match the power of larger units but are more efficient and cleaner-running. Finally, the Vectra FlexPower will be on display, which is powered by the 175 hp E85-compatible 2.0L turbo engine used in the Saab 9-5 BioPower models.

This puts Opel in line with other European competitors, which are also actively downsizing engines and embracing biofuels, etc.
