Prior to going on television on Monday, I spoke to a GM spokesman in hopes of better understanding the business case for the Volt. Perhaps the most interesting thing he told me was that a major impetus for developing the Volt as an Extended-Range Electric concept was GM’s failure to achieve success with three alt-energy concepts (EV-1, Hydrogen, and yes, E-85 ethanol) due to their need for fueling infrastructure. As we talked, it occurred to me that three other less-than-entirely-successful GM “green car” projects might have helped lead The General down the primrose path to the Volt: GM’s BAS “Mild Hybrid,” the Parallel Hybrid Truck system (PHT), and the V8-based “Two-Mode” hybrid drivetrains. He admitted (somewhat grudgingly) that GM’s hybrid sales had been “disappointing” and that the ambitious Volt project was to some extent motivated by this lack of market success. What he didn’t tell me: GM is bringing back the discontinued mild-hybrid BAS system for 2011.

The Chevrolet Volt began life as a marketing concept: “what if,” GM’s finest minds asked themselves, “we could sell a car that could go 40 miles without burning any gasoline?” That goal was achievable (although how easily and regularly remains to be seen), but it came at a cost: if you check out GM’s just-released standard equipment sheet (click on “standard equipment”), you’ll find that the Volt’s gasoline range extender requires premium fuel. What’s strange about this is that the Volt’s 1.4 liter range extender is hardly an overstressed buzz-bomb, making only 80 hp at the crank and 74 hp at the generator. Why then does it need premium? Considering that the Volt would have struggled to pay off its premium over the Toyota Prius anyway, the decision to require premium fuel makes no sense at all.

Last week, the big news coming out of Ford was that the new Lincoln MKZ would be available with a hybrid drivetrain as a no-cost option. With Mercury on its way out, and Lincoln struggling to carve out a niche in the luxury space, that move made a certain amount of sense at the time. What we didn’t know until today is that the “free” hybrid option on the MKZ was only Ford’s opening salvo on the status quo of automotive drivetrain option pricing. Today, with the 2011 Explorer dominating the news cycle, Ford has announced its latest head-scratcher: making the four-cylinder “Ecoboost” engine option more expensive than the more powerful standard V6. Yes, really.

Predicting the future is a risky business. Lincoln Steffens, muckraking journalist and admirer of the Soviet Union said, regarding the then young USSR, “I have been over into the future, and it works.” Steffens apparently wrote that before he actually visited the workers paradise in the early 1920s. A decade later he regretted that endorsement.

Music writer Jon Landau’s prediction was a bit more accurate. “Last Thursday, at the Harvard Square Theater, I saw my rock and roll past flash before my eyes. And I saw something else: I saw rock and roll future and its name was Bruce Springsteen.” Landau was soon to edge The Boss’ original manager, Mike Appel, out of the picture, took over management of Springsteen’s career and production of his music, and did everything in his power to make his prophecy a self-fulfilling one.

Earlier this week I believe that I saw the future of transportation and stationary power and its name is OPOC. That stands for “opposed piston opposed cylinder”, a new engine architecture being developed for production and licensing by EcoMotors, a Troy, Michigan startup.

Reuters reports that Honda has canceled plans to build a new minicar and diesel engine plant north of Tokyo, as the company focuses its product offerings ahead of worldwide emissions standards ramp-ups. Honda’s move away from diesel has been slowly building for years, and the strategy was all but confirmed by the cancellation of a US-market Acura TSX diesel, which was replaced by the V6 TSX. Instead of developing new oil-burners, Honda is focusing on a new hybrid drivetrain capable of powering its larger vehicles. Thus far Honda has kept a conservative approach to hybrids, refining its “mild hybrid” IMA system over several generations. As Honda seeks to improve its fleetwide emissions, this new system (which could be Honda’s first “full hybrid”) has taken on new importance. Honda will officially announce its medium-range plans next Tuesday… and don’t be surprised if it involves a new full hybrid system capable of going toe-to-toe with Toyota’s Synergy Drive.

78 liters of displacement, 18 cylinders, 12 turbocharges and a tame 3,500 hp and 10,300 lb-ft of torque make for one mean Mini. Well, it would if it actually worked. Instead, this will probably just be on static display at this year’s Goodwood Festival of Speed. Fun fact: the engine alone weighs about 15 times what an original Mini did.

As we all know, those oblivious to history are bound to repeat its mistakes. Longtime readers also know I’ve gone down this road before, but the powers of my Twitter news feed shoved extra grist into this particular mill. Behold: Alain Raymond’s blog about the death of the V8 engine. Raymond’s weakest argument revolves around one fact: V8’s did lose mainstream appeal shortly after the demise of the Butterfly Collar. But Alain wishes to beat this dead horse for some misguided reason.

Do you buy the base four-cylinder, or upgrade to a V6? For most car-purchasing decisions, this is an important question to think through. And usually the trade-offs are simple: you can pay more for more power and less efficiency with the V6, or save money and gas with the four-potter. And with fuel prices staying volatile, four-cylinder engines are becoming all the more popular: for example, Hyundai’s new Sonata has been engineered to be four-cylinder only. But according to Consumer Reports, the differences between the V6 and the four-cylinder option aren’t always as clear as you might expect.

The National Academy of Science’s National Research Council has released a comprehensive report on fuel-saving technologies and their associated costs [full report available online here, summary in PDF format here], and it’s data-licious. Just about every currently-available (within the next five years) efficiency-improving technology was assessed, not just for efficiency gains, but for cost as well… but let’s wait on the cost part for just one moment. Above, you can see the study’s findings in regard to efficiency gain available through various near-term technologies, as applied to vehicles with 4, 6 and 8-cylinder engines. It should come as no surprise to find that conversion to Hybrids, diesels and dual-clutch or continuously-variable transmissions offer some of the greatest benefits… but what about those costs?

Sajeev, my friend Polly, an avid sheepdogger, wants to know how much weight her early to mid-80s Vanagon can pull. Specifically, she is interested in buying a 700 lb trailer, in which she would haul up to six sheep, each of which weighs 100-150 lbs. Thus, she could end up pulling as much as 1,600 lbs, and who knows, maybe more. How much can she pull without damaging her pride and joy?

The Vanagon has a ’94 engine from a Subaru Legacy–she doesn’t know which engine–but is otherwise all old Veedub. 212k miles on the car, less on the engine, but how much less is unknown. No rebuilds that she knows of. I don’t believe she’s going to be doing any major hill climbing.

Right now, the [Volt’s] propulsion system is too expensive, even with using an existing engine… We have a strategy to go rotary engines or a two-cylinder [gas] engine making 15-18 kW. I have driven the car already. Rotary has a higher fuel consumption but here’s the advantage [holds up his hands to form round, frisbee-sized shape] — packaging.

GM’s Karl Stracke talks Volt 2.0 with InsideLine, and yet never quite explains why a less fuel-efficient rotary generator would even be on the table. Or how a rotary (let alone the also-mooted diesel generator) would be the solution to high drivetrain costs. How much room does the (implicity and reputationally) more-efficient two-cylinder really take up? Wasn’t the only mass-market rotary-powered car left in the wild, the Mazda RX-8, just canceled for flunking European emissions standards? Can’t the rotary engine die with a little dignity?

Common decency demands that this flagrant of fanbaiting be reserved at least until the first-gen Volt hits the streets.

The auto enthusiast community is far too fragmented to ever achieve real consensus on any issue, but if there’s a single authority on performance-oriented cars, it’s Britain’s enthusiast bible evo Magazine. So when evo bashes an enthusiast-targeted model, it’s usually worth taking note of. The latest print issue of evo includes a Chris Harris review of Audi’s range-topping RS5 coupe [online summary here], the 444 hp, V8-powered flagship of its A5 lineup, and from line one the reader can tell that something is rotten in the state of Quattro GMBH. Harris describes an attempt to blow the doors off a 328 hp S4 camera car, only to find that, three gears later, his $15k more expensive coupe had barely gained any ground on the supercharged V6-powered S4. So, what gives?

Despite breaking new ground in the field of brand leverage with its Ferrari World Abu Dhabi theme park, Ferrari does seem to have lost the plot a bit in relation to its “other” business building expensive sportscars. Ferrari’s abandonment of the manual transmission might be justified by faster lap times at Fiorano, and the lightning-fast, dual-wet-clutch transmissions that replace them certainly seem to help keep the Scuderia at the bleeding edge of technology (even if they’re designed and built by Getrag). But underlying the faster times, higher speeds and “digital supercar” honorifics from the motoring press, there’s a sense that Ferrari’s progress must accommodate an ever-more ambitious business plan as much as design the world’s most capable and emotive sportscars. And it’s starting to bear some troubling fruit.
