With the federal deficit balooning out of control, President Obama’s National Commission on Fiscal Responsibility and Reform has publicized its preliminary proposals, and goodness are there a lot of them. But only one of the commission’s proposals gets to the heart of this nation’s automotive future: a proposal to increase America’s gas tax. Federal fuel taxes currently stand at 18.4 cents a gallon for gasoline and 24.4 cents for diesel fuel, but the commission has proposed a 15 cent per gallon increase, to take effect starting in 2013.

Hyundai’s Sonata overhaul has been well-received by critics and customers, and the next-gen Elantra looks set to move the magic to the C-segment. But what of the Accent? If there’s a vehicle left in Hyundai’s lineup that recalls the bad old days of Hyundai’s bargain-basement past, it’s the current sub-$10k base price Accent. Of course, that’s all about to change, as a new Accent is hitting the roads in Korea… and like most of Hyundai’s new product, it looks like a huge step up from its predecessor. TTAC’s man in Korea, Walter Foreman, was kind enough to send in this mega-dump of over 80 images of the new Accent, noting

The car is 172 inches in length with a 101.2 inch wheelbase and a height of 57.3 inches. No news on the claimed curb weight yet.
The 1.4 liter engine is rated at 108 hp and 37.8 mpg with the 5-speed auto and 42.3 with the 6-speed manual [all mpg numbers on Korean test cycle].
The 1.6 liter engine is rated at 140 hp and 39.3 mpg with the 6-speed auto and 42.8 with the 6-speed manual.
The juggernaut rolls on…

Automotive News [sub] reports that the new GOP majority in the house of representatives will likely mark a shift in the political dynamic between the industry and the US government, as Republicans shift from noisy protest of government support for the industry towards orchestrating reductions in industry regulation. And, according to the Alliance of Automotive Manufacturers, the first victim of the new Republican House could be the Motor Vehicle Safety Act, a set of sweeping regulations aimed at preventing recall scandals like the Toyota unintended acceleration fiasco that took place earlier this year. House Republicans plan on holding hearings on that bill, which has passed committees in the House and Senate but has not yet faced a full vote by either full body. Says National Auto Dealers Association lobbyist Bailey Wood

There will be much more oversight, and the process will slow down

But House Republicans will also face their own challenges. With Democrat JerryBRown winning California’s gubernatorial race, national lobbyists will have a harder time resisting ever-increasing emissions standards, as California is the sole state with authority to independently regulate auto emissions. Though Republicans are likely to support the industry’s resistance to increased fuel economy standards, they will require help from the White House in order to, as the AAM’s Dave McCurdy puts it

rein in some of the more exuberant tendencies in California

With battles brewing over safety and emissions legislation, 2011 is shaping up to be an interesting year for followers of the politics of automobiles.

We’ve already been impressed enough with the McLaren MP4-12C’s 3.8 liter turbocharged V8 to say it “looks like mechanical sex” and give it its own gallery. The super-compact, direct-injected engine develops in the neighborhood of 600 hp, giving the new McLaren the dangly bits to show a (similarly-priced) Ferrari 458 the way around a racetrack. And though McLaren clearly thinks the MP4-12C’s race-tested abilities will help build its brand into the new race-nerd standard, it’s also beating Ferrari at a new game that will become increasingly important with time: the C02-per-horsepower game. Ferrari’s 570 hp V8 emits 320 grams of C02 per kilometer, giving the Fezza a rating of .56 grams of C02 per km per horsepower. McLaren’s goal for its not-quite finalized MP4-12C drivetrain is a C02 emissions rating of below 300 gm per km, which would give the supercar closer to a .5 gram per km per horsepower rating. And though the direct-injected, downsized and turbocharged engine helps keep that number down, the MP4-12C’s dry weight is also 176 lbs lighter than the 458’s (2,866 versus 3,042).

Toyota and Fiat may not be setting European sales charts alight, but according to a recent analysis of per-vehicle CO2 output, the two automakers are on the cusp of meeting the EU’s stringent 2015 standard. Automakers competing in Europe will have to reduce their carbon emissions to 130 gm/km by 2015, a huge challenge for firms like BMW, Mercedes and Volkswagen, which currently have average emissions of 151, 167 and 153 grams per km respectively. Fiat and Toyota, on the other hand, have already reduced their emissions to 131 and 132 grams per km, putting them within a sneeze of the 2015 standard. But the auto industry never though that any of its firms would be on track for overcompliance. In fact, the AFP reports

In 2008 carmakers successfully pushed back from 2012 to 2015 the deadline for technological innovation, allowing them to meet stipulations, in exchange for a commitment to drop to 95 g/km by 2020.

Despite not insignificant loopholes, they can be heavily fined if they miss these targets as the EU strives to meet wider aims in reducing emissions of harmful gases blamed for negative climate change effects.

The need to expand automotive brands while improving fuel economy is driving automakers to some interesting lengths of late. From GM future concepts that have more in common with a Segway than a Cruze, to Honda’s U-3X and Chrysler’s ill-fated PeaPod, automakers are sending strong hints that the future will be smaller and decidedly less car-like. And MINI and Smart recently took this trend to its logical conclusion, each announcing that they would build (or, more precisely, re-brand) scooters… or as they call them, “alternative mobility concepts.” Which raises the question: what’s a scooter brand to do? Well, Piaggio, maker of the Vespa and other scooter-based “alternative mobility concepts” isn’t going to just drone off into that good night, and it’s fighting back by creating an “alternative” to its core scooter products: a four wheeled car-like “mobility concept.”

OK, so the EMAV PRU (Electric Motors and Vehicle Company Power Regeneration Unit) isn’t expected to go on sale until sometime next year, but it’s one curious approach to the “range anxiety” problem that caused GM to develop the Volt as a range-extended EV rather than a pure battery-only EV. The PRU takes a simple concept, a trailer that can both store goods and generate 25kWh of electricity from a 750cc diesel engine in order to extend range, and makes it considerably more complicated than it needs to be. For one thing, it’s self-propelled, necessitating on-board lithium-ion batteries, as well as an electric drive unit.

As a result, the projected pricetag comes to a prohibitive $15,000, and the weight reaches an EV range-sapping 1,220 lbs. And for all that, wouldn’t a $15k hatchback make a better “range extender” than this cumbersome trailer? On the other hand, a trailer like this just might work as a rental item, offering a portable generator as well as range extension that its makers say will work with any electric car. But would something like this be more appealing as a simplified, lighter unit (non-self-propelled), or will add-on range extension always struggle to offer more for money than having a gas car as a compliment to an electric car? Given that American families typically have several cars anyway, the answer would appear to be yes… [via GM-volt.com]

We’ve hosted our fair share of diesel skepticism over the years here at TTAC, but the latest data on diesel take rates indicate that oil-burners are more popular than you might think. Dieseldriver.com broke down sales of every passenger vehicle with a diesel option, and found an overall take rate of 32 percent over the first three quarters of 2010, and trending upwards. In the third quarter, over half of the two Audis with diesel drivetrains optional were ordered as oil burners, and the vast majority of Jetta Sportwagons sold are diesel-powered. And no wonder. Modern diesel engines can be glorious things, offering gobs of torque, shocking levels of refinement and great fuel economy. Diesel prices may have climbed somewhat in the last year or so (it’s no longer cheaper than gas), but they’re close enough to make diesel a real option. Well, at least for buyers of German cars.

Editor’s Note: On Monday, TTAC’s Martin Schwoerer wrote about a planned record-breaking non-stop run of 600 KMs, from Munich to Berlin, with a car that was equipped with a “revolutionary” electric battery system. Something smells funny, he said, and vowed to donate 100 Euros in case the drive was completed. Well, it was. So, how does it feel to have pie on your face?

How about Vegetarians Against the klan? Or maybe the Tugg Speedman Foundation? No, there are probably better organisations to give my money to. Guess I’ll ask the Best & Brightest… Read More >

This is America man… you can have your electric car and your freedom too.

There’s no doubt about it, the Chevy Volt sounds best when you’re just selling the concept. And no wonder: the concept came was born of Bob Lutz’s unique insight into the American psychology… not to mention a psychologically-charged desire to rub the Prius’s nose in some mud. But what nobody seems to be pointing out is the fact that the flip side of being “all things to all people” is fundamental compromise. And in the case of the Volt, the risk is that it won’t be as good of an electric car as the Leaf and it won’t be as good of a gas-powered car as any other hybrid. If GM’s pitch that Volt equals EV plus Freedom doesn’t take, the car will go nowhere fast… so how does the first attempt strike you?

The recent bailout of America’s auto industry began with approval of so-called “Section 136” loans to help automakers retool factories for higher-efficiency automobiles. Ford, Nissan, Tesla and Fisker have already received their portions of the Department of Energy  loans, but GM and Chrysler have had their payouts delayed due to the program’s strict “viability” requirements. But now Reuters reports that Chrysler’s request for $10b in low-cost government retooling loans is nearing approval. It’s not clear how much of that $10b will be approved, but according to Pentastar spokesfolks

Our application covers a wide variety of technologies including electric vehicles, (gasoline/electric) hybrids and advanced gasoline engine technology

Chrysler still owes some $5.7b to the US Treasury, and the cost of servicing that debt (interest on ChryCo’s existing government debt ranges from 7.22 to 14.33 percent) is considered a major reason for Chrysler’s second-quarter loss this year. GM is also seeking over $10b in 136 loans, but with only $16.5b remaining in the $25b 136 fund, either Chrysler or GM will have to receive less than their entire request. GM’s request will reportedly be approved sometime after Chryslers.

Although the finished product works well enough, it’s also becoming increasingly apparent that the Volt missed two key project goals. GM’s oft-stated promise that the Volt would achieve 50 mpg in CS mode is history. The fact that GM felt the need to optimize the fuel consumption of the Volt by using premium (required, not just recommended) indicates how rather inefficiently its serial-predominant hybrid system works. It’s not a matter of ragging on about that; it’s just a surprise to those of us who argued endlessly which system (serial or parallel) was more efficient.

And now another long held Volt assumption is deflated. Based on GM statements made during the Volt’s long development, the universal understanding was that the Volt would use 8 Kwh of its 16 Kwh battery pack to achieve its 40 mile AER goal. It now turns out that 10.4 Kwh will be utilized. Sounds like small potatoes, but there are three not insignificant consequences as a result: Read More >

We live in annoyingly ideological times, in which people get worked up about gay marriage, Christopher Bangle, or what religion their neighbor belongs to. This is foreign to me. If it works for you, then go for it, I always say. You like some wheels, you buy ’em; if you don’t, don’t.

So, it’s hard for me to understand what the fuss is about the Chevrolet Volt. It’s just a car, for Pete’s sake! On the other hand, I am a notorious gearhead and can appreciate the importance of what seems to be a totally new automotive concept. It’s new, but does it point toward the future? Let’s discuss it.

My initial self-appointed assignment was to come up with a comprehensive cost analysis of the Volt in comparison to the Prius and other vehicles. I first took this on two and a half years ago, and the results from that gazing-into-the crystal-ball exercise are actually still remarkably accurate, except for the Volt failing to meet its then-promised 50mpg fuel economy. The task, given the infinite variables, is essentially impossible, and thankfully, I was forwarded a link to this Electric Car Calculator. It’s far from perfect, given that it doesn’t account for depreciation, finance costs, leasing, maintenance, etc. What it does do is allow you to input your driving regime, both weekdays and weekends, electric and gas costs, and come up with a comparison for overall fuel costs with your choice of another vehicle; a good start: Read More >
