It’s been 12 years since BMW offered a four-cylinder engine on a US-market offering, but starting this October, US dealers will begin offering new “TwinPower”four-pot versions of the Z4 roadster and 5-series sedan. And, as BMW’s US-market boss Jim O’Donnell explains to Automotive News [sub], there’s no reason to fear the four… anymore.

It wasn’t in line with our image, because it didn’t have the performance of the six cylinder. We were selling ourselves as the ultimate driving machine and really it wasn’t. Now that the engines have developed so far, it’s not an issue at all.

But now BMW is offering four-bangers because they offer an even better driving experience, right? Less weight, better turn-in, that kind of thing… right?

Today’s announcement of a memorandum of understanding between Ford and Toyota, uniting the two firms’ pickup truck hybrid drivetrain efforts, took quite a few industry-watchers by surprise this morning. As the industry leader in hybrid technology, Toyota has limited past hybrid cooperation to licensing its drivetrain wholesale to Nissan and a patent-sharing agreement with Ford. Moreover, the last big alliance aimed at developing hybrid technology for full-sized pickups, the Two-Mode V8 hybrids developed jointly by GM, Chrysler, Mercedes and BMW, have been a huge flop on the market, with the German partners walking away from the technology after using it in only a single application each (X5/X6, and ML Hybrid). Though Toyota and Ford have worked together to prevent a messy patent war over hybrid technology, there was little to suggest that they would take the cooperation any further, let alone join forces to hybridize full-size pickups. But if you’re looking to the marketplace to explain the Ford-Toyota tie-up, you’re looking in the wrong place: this is all about the freshly-announced CAFE standard and its generous credit system.

We’ve heard about range-extending trailers which could allow EVs to become range-extended plug-in hybrids, but how about this: a trailer with its own battery storage, regenerative braking and even electric-drive assist. That’s the idea behind German camper trailer firm Knaus Tabbert’s concept, on display this summer at Düsseldorf’s Caravan Salon. And besides adding hybrid capabilities to the car that happens to be towing the trailer, the trailer itself can use the energy gained through regenerative braking for its climate control, refrigerator, lights and more. Autobild reports:

Here’s how it works: Two AC generators, each with 850 watts of power are connected to each wheel of the caravan. The energy generated during the drive is stored in lead-acid batteries, which add an extra weightof 70 to 80 kilos. Starting at a speed of about ten km/h the generators begin feeding electricity to the batteries, and the maximum charge power is available by about 35 km/h. If the Caravan’s electricity use is limited to seven hours per day (total power 100 watts), campers can take advantage of up to four days of independence from an external power supply.

Even if you don’t understand German, you might enjoy the video above, which demonstrates many of the promised functions of this system. Outside of videos though, the system still is not ripe for public sale, according to its developer. There’s still no word on when it will be ready or how much it will cost, but it’s one of many small ways that hybrid technology is seeping into nearly every form of transportation.

Few will be surprised to hear that Chrysler Group will end production of its Dakota compact pickup truck next Tuesday, as sales of all small-to-midsized pickups have cratered over the last decade. Indeed, the Detroit News reports that the end of Dakota production will result in the layoffs of only 39 employees, although that number may climb as high as 150. In any case, the end of Dakota production is just the tip of the iceberg: Ford’s Ranger goes out of production in December of this year, and GM’s Colorado/Canyon twins will be discontinued sometime next year. Though Dodge plans to bring a minivan-platform-based AWD “lifestyle pickup” to market as a 2014 model, and Chevy is planning to build a North American variant of its new Global Colorado for the 2015 model-year, we’re looking at a several-year interlude in which no American OEM will offer a small pickup in the US. And looking at this chart, you almost can’t blame them…

With the environment taking an ever-larger place in automotive advertising, it’s interesting to note that Fisker’s latest brochure puts green in its place: behind sexy. Of course these sultry images [via BusinessInsider] aren’t free from environmental overtones, featuring taglines like “designed to get you hot, not the planet,” but it’s clear that Fisker is more heavily relying on the most traditional tool in the advertising playbook. Why? For one thing, even though Fisker is delivering Karmas, the EPA has not yet certified its efficiency rating… so we don’t even know how environmentally friendly it is yet. For another the Karma’s main rival, Tesla’s forthcoming Model S, is pure electric and therefore more appealing to wealthy environmentalists. Finally, unlike environmental messaging, sex doesn’t remind people that Fisker was the beneficiary of over half a billion dollars in government loans. Plus, sex is still, well, sexy. The more things change, the more they stay the same…

Who’s ready for some politics? With the presidential election still over 14 months away, recent Iowa straw poll winner Michelle Bachmann is upping the campaign promise ante by telling a Greenville, SC crowd

The day that the president became president gasoline was $1.79 a gallon. Look at what it is today. Under President Bachmann, you will see gasoline come down below $2 a gallon again. That will happen.

Without even taking a side in the muck of presidential politics, it’s plain to see how ridiculous this statement is. As Politico helpfully notes:

Bachmann didn’t detail how she would cut the price of gasoline, which is tied to the global price of oil. [Emphasis added]

Personally, I think gas should probably be taxed to a point where Americans pay about what the rest of the world does, in order to pay for the externalities of oil consumption. Most auto execs agree, arguing that America’s artificially low gas prices play hell with product planning. But even (or is that especially) if you’re a hard-core anti-tax free-market fundamentalist, Bachmann’s statement should be treated with scorn. After all, markets, not presidents, should be setting oil prices. But what’s principle (or even good practice) when compared to the need for political pandering?

With Chevrolet already offering a Cruze Eco, WardsAuto reports that the forthcoming Cruze diesel made a case for itself based on attributes that go beyond mere efficiency. Which is interesting because a GM source tells Wards that the Cruze diesel will get around 50 MPG on the freeway… and unlike the Eco, it will achieve that high number with an automatic transmission (the Cruze Eco’s 42 MPG highway rating is only for manual transmission models). Equally importantly, the oil-burning Cruze will return better performance alongside better efficiency, with 147 HP and 236 lb-ft, compared to the 1.4T engine’s 138 HP and 148 lb-ft, which would make it the performance model of the range… which some say is just what the Cruze needs.

Joseph Lescota, chair of the Automotive Marketing Management Dept. at Northwood University in Midland, MI, thinks a diesel Cruze will draw buyers.

“Chevrolet has a great price-point vehicle that has tremendous eye appeal and options but may not meet the performance needs of a select market group,” he tells Ward’s.

A diesel version would hit that group between the eyes by adding a sturdy engine, extra torque and top-end performance to the mix, he says.

GM executives meanwhile highlight the diesel option’s value as what GM North America boss Mark Reuss calls “a hedge against the unknown.” Only three percent of current US sales are of diesels, but as American brands start rolling the oil-burning options out, and as Americans are exposed to their higher performance and efficiency, that segment could just grow. After all, who doesn’t want more performance and more efficiency for a mere $1k-$4k premium?

Among the many new SKYACTIV technologies that Mazda plans on introducing to its global lineup, a unique start-stop system is one of the most important. Initially Mazda had decided not to bring its idle-stop system to the US as the EPA system didn’t measure a major improvement in efficiency, but ultimately the decision was made to make all of its vehicles idle-free by 2015. But an early test of a SKYACTIV idle-stop-equipped Mazda2 by Automotive News [sub]’s Hans Greimel reveals an interesting characteristic:

a funny thing happened when I paused for a red in Tokyo’s harbor district.

After a few moments of silence, the engine clicked on, as designed, to help keep the air conditioner going. OK, that’s normal. But as the engine jumped to life, so did the steering wheel. To my surprise, I found the engine’s start-up vibrations turning the wheel to-and-fro in my loose grip.

In his New York Times comparison of heavy-duty pickup trucks, Ezra Dyer opens with a provocative comparison:

Heavy-Duty pickup trucks are the supercars of the truck world. They have more power than drivers are likely ever to exploit, and bragging rights depend on statistics that are, in practical terms, theoretical.

How does he figure?

While you can’t buy a diesel engine in a mainstream light-duty pickup, heavy-duty pickups now offer propulsion suitable for a tandem-axle dump truck.

I’m not exaggerating. Ford’s 6.7-liter Power Stroke diesel V-8 packs 400 horsepower and 800 pound-feet of torque; the base engine in a Peterbilt 348 dump truck offers a mere 260 horsepower and 660 pound feet. Does your pickup really need more power than a Peterbilt?

I’m guessing most HD truck owners won’t take kindly to the question, especially coming a scolding Gray Lady. But if you read the full review, you’ll find that Dyer was able to locate at least one contractor willing to admit that he realized he just didn’t need his HD’s overabundance of ability. It goes against the grain of the “bigger, faster, tougher, more” marketing message that has helped make trucks such a huge part of the American market, but is it possible that the tide is turning? Have pickups improved too much? The huge sales of Ecoboost V6-powered F-Series certainly suggests the we may just be moving towards a more pragmatic truck-buying market…

You know those things that you never thought you needed, but once you had them you realized you never wanted to live without them again? According to Jean-Claude Kihn, Goodyear’s senior vice president and chief technical officer, it’s time to get ready for another such technology:

“A tire that can maintain its own inflation is something drivers have wanted for many years. Goodyear has taken on this challenge and the progress we have made is very encouraging. This will become the kind of technological breakthrough that people will wonder how they ever lived without.”

Goodyear doesn’t know when its “Air Maintenance Technology” will make it to the streets, but thanks to funding from the US and Luxembourg governments, they’re making progress.

With US gas prices at some of the lowest levels in the world, it’s not too surprising that US consumers aren’t overly anxious to go electric, but what about in Germany, where gas prices are near double the US’s? According to Thilo Koslowski of Gartner Research, interest in EVs remains low there as well, and the big gainer in recent years has been hybrid technology… at the expense of the once-ubiquitous diesel, demand for which has “peaked” according to Koslowski’s research. Says the man who coined the term “the trough of disappointment,”

Although the majority of German consumers continue to see EVs’ benefits in environmental and socioeconomic implications, broad adoption of EVs will remain low as long as current offerings don’t meet drivers’ practical usability and cost-saving requirements. To expand from early to mainstream EV adopters in Germany, automotive companies must focus on technology innovations, offer pricing strategies that are aligned with established premiums for diesel and hybrid powertrain options and develop diverse EV model mixes targeted at younger consumer segments that have higher EV interest levels than older demographics… E-mobility will become a viable addition to future transportation scenarios in Germany, but automotive companies and the German Government must address marketability requirements of EVs, prioritise technology investments and continue to promote cross-industry collaboration. Future mobility concepts will consist of diverse powertrain choices and business models that will leverage technology to satisfy consumers’ transportation needs while challenging traditional car ownership.

Steampunks and Atomic Age nuts rejoice! WardsAuto reports that Connecticut-based Laser Power Systems is “getting closer” to developing a prototype electric car which develops its power using the radioactive heavy metal Thorium. According to LPS’s CEO,

when thorium is heated by an external source, it becomes so dense its molecules give off considerable heat. Small blocks of thorium generate heat surges that are configured as a thorium-based laser… These create steam from water within mini-turbines, generating electricity to drive a car. A 250 MW unit weighing about 500 lbs. (227 kg) would be small and light enough to drop under the hood of a car… Because thorium is so dense, similar to uranium, it stores considerable potential energy: 1 gm of thorium equals the energy of 7,500 gallons (28,391 L) of gasoline. Prototype systems generate electricity within 30 seconds of firing a laser. This can feed power into a car, without the need for storage.

What about radioactivity? (Read More…)

Though the next-generation of Mazda’s rotary engine has been in development since 2007, and has been the subject of several TTAC Wild-Ass Rumors, WardsAuto reports that the unique engine design could well be reaching the end of its life.

Kiyoshi Fujiwara, Mazda executive officer-product planning and powertrain development, says there is “huge discussion” within the Hiroshima, Japan-based company whether to continue on with a rotary engine.

Fujiwara says economic hardship has some top brass looking for programs to cut, and that the engine program is on the list.

Continuing development of the rotary has been halted for now, but he hopes it will resume in the future, noting the technology is a part of Mazda’s DNA.

Without identifying what exactly they are, Fujiwara says three major problems were identified with the current generation of rotary engine, but that two of the three have been overcome. Still, Mazda says that only one thing will save the rotary engine at this point: success with Mazda’s new suite of SKYACTIV technologies. If these fuel-saving measures spark new interest in the Mazda brand, says Fujiwara, then Mazda might have enough cash to invest in its rotary engine. Alternatively, a Mazda-developed Wankel engine could be used as an electric range-extender. In any case, don’t expect a new Mazda rotary before 2017… if ever. Here’s hoping Mazda is able to keep this unique, distinctive drivetrain alive for future generations of enthusiast drivers.

For most Americans, the term “small car” typically refers to a C-segment sedan like the Honda Civic or Ford Focus, cars that now qualify as midsizers in many key metrics. Subcompact, or B-segment cars are generally considered the smallest of the small, as their name implies… but ask an American to describe a car smaller than a subcompact, and they’ll likely look at you quizzically before hesitantly suggesting “Smart car?” Yes, the A-Segment, known in Europe as the “City Car” or Microcar” class, is such a rarity in the US that it’s basically synonymous with the one car “competing” in it (Fiat’s 500 hasn’t quite broken into the public consciousness yet).

But, with Chevy execs confirming once and for all that the on-again-off-again (for the US) Chevy Spark (a.k.a. Daewoo Matiz Creative) will in fact be sold in the US (likely as a 2013 model) early next year, the American A-segment is about to get a whole lot of attention. But the question is this: does the fact that America’s first new A-segment car in a decade is a Chevy help or hurt the segment’s chances (consider that previous US A-segment cars like the 500 and Smart are positioned as premium offerings)? Is this car, with its 80 HP/82 lb-ft, 1.2 liter engine a pioneering game-changer that will introduce America to a whole new world of tiny cars, or is it just CAFE compliance fodder? One thing is for certain: everyone from Hyundai to Ford (which have the i10 and Ka waiting in the wings) is going to be watching the Spark with great interest.

I am sitting in a parking garage in a throng of torpid auto-journalists, nearly all of whom are wearing the same glazed expression of terminal information overload. On-screen, molecules of fuel and air are doing a complicated little computer-animated dance, as narrated by Susumi Niinai, program manager at Mazda’s powertrain development division. His English, while Japanese-accented, is better than, y’know, mine, but the concepts he’s explaining approach the limit of comprehensibility to the lay-person. Mind you, it’s a pretty nice parking garage.

Some of you, like me, may have been hearing all the rumblings about Mazda’s new SKYACTIV technologies and been wondering whether it’s going to turn out to be a series of technological breakthroughs or, alternatively, a load of complete cobblers thought up by some Zoom-Zoom marketing guru.

Good news everyone! It’s the former. Bad news everyone! I have to try to explain it to you. And I borderline don’t understand it myself. Here goes…
