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?

Financial Times calls “Volkswagen a long-time skeptic about hybrid and electric cars.” As a long time observer of the Wolfsburg boys, I have to agree. Despite green initiatives for public and political consumption, their private position has been that the consumption and emissions of a hybrid could be achieved with their low displacement supercharged engines and some weight savings. Some electric initiatives notwithstanding, this position has not changed. Case in point: Their new Touran. Read More >
The long-simmering dispute over hybrid technology patents between Toyota and the Florida engineering firm Paice is rolling on, as Bloomberg BusinessWeek reports that a judge from the U.S. International Trade Commission refused to dismiss the Paice suit. That suit builds on an earlier ruling requiring Toyota to pay Paice royalties on its Prius, Highlander Hybrid and RX400h sales (Toyota is challenging the amount of these royalties, ordered by a federal judge in Texas).
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.
No details yet, just an Inside Line confirmation from GM’s Karl Stracke that a seven-seat, Lambda-platform crossover “is absolutely a go.” It has long been rumored that the Cadillac Escalade would be replaced by a Lambda-platform crossover. The Cadillac crossover will join the Buick Enclave, Chevrolet Traverse, and GMC Acadia, as the Lambda becomes the only platform shared by all four of the General’s “core” brands (and previously, the Saturn Outlook as well).
On the strength of Coda Automotive’s plan to launch a $45,000 EV conversion of a Chinese Hafei sedan, our coverage of the EV startup (formed from the ashes of Miles Electric Vehicles) has pretty much been limited to the conclusion that it “make the Volt look good.” And as the competition has moved forward, the venture isn’t looking any better by comparison. With news that Nissan will be able to manufacture its Leaf batteries for the low, low price of under $400 per kWh (if all goes to plan, anyway) rocking the EV community, Coda’s proposition of asking $45,000 for a 33.8 kWh lithium-ion battery with a Chinese compact sedan attached to it has not aged well (conservatively assuming the Hafei costs $15k, that still breaks out to nearly $900 per battery kWh, as crude as the comparison may be). But don’t let a little common sense worry you about Coda’s future: according to a company press release [via PRNewswire] the firm just scored a cool $58m in an oversubscribed fundraising round that leaves it with over $125 in total investments.
About a half-hour after TTAC’s 15 Years of Compact Car Sales graph went up today, the normally enthusiast-oriented car blog Jalopnik gave the internet its own take on compact-car segment analysis with a post titled The Ford Fiesta Will Dominate The Small Car Segment. Some might question how this is supposed to jive with Jalopnik’s alleged commitment to “awesomeness,” but our concerns are far more prosaic. Examples: the absence of the Fiesta’s actual competitors like the Honda Fit, Nissan Versa and Toyota Yaris, and the absence of interior volume comparisons which would expose this “comparison” for the fraud it is. And that’s just for starters…
Ford’s Fiesta subcompact has earned a top EPA rating of 40 mpg on the highway, and 29 mpg in the city, reports Automotive News [sub]. Those numbers are for Fiestas equipped with an optional six-speed autobox; manual transmission models get a 37/28 mpg rating. By comparison, auto-equipped versions of competitors like the Honda Fit (35/28) and Toyota Yaris (35/29) come up short on highway mileage in particular. But this isn’t the first time Ford has claimed 40+ mpg for one of its cars: the Fusion hybrid carries an EPA city rating of 41 mpg, despite coming up short of its government-endorsed rating in several real-world tests (although not as shockingly as Chevy’s Equinox, for example). But the EPA testing regime is hardly perfect anyway, so let’s just wait and see what the test drives yield before we start stringing up the piñata.
Officials working with the Department of Energy tell the Detroit News that GM and Chrysler face no major obstacles in their quest for huge retooling loans from the DOE’s Advanced Technology Vehicle Manufacturing Loan program. GM is seeking $14.4b and Chrysler has asked for $8.55b in low-cost government loans. Says Matt Rogers, a senior adviser to the Energy Department
Project finance details need to be worked through, but those things are working out just fine as we work directly with the companies. It’s really a process of making sure that each of the projects that they have are in fact competitive.
Er, competitive compared to what?
Hybrid/electric cooperation between Volkswagen and Suzuki appears to be yielding fruit already, as the Japanese automaker is announcing a plug-in hybrid version of its Swift subcompact. According to Bloomberg BusinessWeek, the new plug-in will combine lithium-ion batteries supplied by Sanyo, paired with a 660cc three cylinder engine. An electric-only range of just under ten miles is being thrown around, after which the gas engine will apparently be used to generate electricity along the lines of GM’s Volt Extended-Range Electric concept. 60 test units of the plug-in Swift will be delivered to Japanese dealers for testing “later this year,” although official plans regarding when and where the vehicle will eventually go on sale have not yet been announced. Suzuki had previously said that one of the goals of its cooperation with VW was to develop electric vehicles for the Japanese market.
A study by Bosch, using R.L. Polk registration data [via GreenCarCongress], finds that fears of a diesel crash in the US might be overblown. The study found that vehicles offering diesel powertrains as an option recorded 30 percent diesel take levels. By comparison, ten percent or fewer chose hybrid versions of the Camry and Escape, although volumes of those vehicles are higher than the exclusively German nameplates that offer diesel options. In any case, these take numbers are certainly higher than the market had predicted. The diesel take rates by model are:
- Audi A3 TDI: 20%
- Audi Q7 TDI: 30%
- BMW 335d: 8%
- BMW X5 xDrive x35d: 17%
- Mercedes-Benz GL 350 BlueTEC: 18%
- Mercedes-Benz ML 350 BlueTEC: 13%
- Mercedes-Benz R 350 BlueTEC: 12%
- VW Jetta TDI (Sedan and Sportwagen): 49%+
- Volkswagen Touareg TDI: 33%
Technology Review reports on Levant Power’s “GenShock” technology, which generates electricity by converting the kinetic energy of suspension travel into electricity. And electricity generation isn’t the whole story: the entire suspension is an actively-controlled, dynamic system that improves performance as well as efficiency in a turnkey package.
Levant has developed a modified piston head that includes parts that spin as it moves through the oil, turning a small generator housed within the shock absorber. To improve vehicle handling, the power controller uses information from accelerometers and other sensors to change the resistance from the generators, which stiffens or softens the suspension. For example, if the sensors detect the car starting a turn, the power controller can increase the resistance from the shock absorbers on the outer wheels, improving cornering, says David Diamond, the vice president of business development at Levant.
The long awaited Polo GTI is not long awaited anymore. Except if you live in the U.S.A. Then you can wait until the proverbial cows come home. Or until someone at VeeDub has an epiphany and sends the thing stateside. (I still remember how long it took them to introduce the original Golf GTI to the U.S. Forever. We begged them. “There is a 55 mph speed limit,” they said. “They buy Porsches,” we said. “That’s something else,” they said. “They buy muscle cars,” we said. “Stop bugging us,” they said. And how long did it take them to decide to bring a civilian version of Polo to the U.S.? What, 35 years?)
The textbook example of engine downsizing that gets 180 hp out of its twincharged (turbo and supercharger) pintsized (1.4 liter) TSI engine, while making owners of gas stations increase their anti-depression medication with a 40 mpg US rating (estimated) is being officially launched today in Germany. In style: At the Nürburgring.
We live to serve here at TTAC, so when our faithful commentators requested a comparative graph of Chevy Suburban and Tahoe Sales from the heart of the SUV boom, who were we to say no? And sure enough, there are some interest lessons to be learned from the exercise. In 1999, as the SUV boom headed for the stratosphere, the ‘burban actually passed the Tahoe in terms of volume for one year. But the fad wouldn’t last: Suburban sales peaked in 2001, a year before the Tahoe topped out at nearly 209k units. The Suburban also fell further, suffering big year-over-year losses until a pre-gas-shock uptick in 2007, a year after the Tahoe recorded its first post-peak upswing. Counter-intuitively, the 2008 gas shock actually hurt Tahoe volumes even worse than Suburban, shedding over 50k units (or about 60 percent) compared to 2007 levels. Over the same period, the Suburban “only” lost 30k units of volume (about 55 percent).
Considering the Suburban so essentially captures the tenuous line between myth and reality in American life, it’s a pity we don’t have 75 years of sales data to put some hard numbers behind the nameplate’s 75 years of history. Luckily, our data does go back to 1995, when America’s whirlwind romance with the SUV was just beginning to get serious. Given that, as Paul points out in today’s history, Suburbans didn’t become popular as family haulers until sometime in the early eighties, it’s safe to assume that 1996-2004 represents the absolute high-water mark for the nameplate’s volume. And ye gods has that volume dropped off ever since.
