Hello Sanjeev,

I have a problem and hope you can help me. My Cadillac Brougham with the 307 V8 smells like gas under the hood. This is intermittent and the last time it was in the shop the mechanic found no leaks under the car or around the carb. (Read More…)

Public beta tests are common in the computer world where a group of fanatics pound your beta to death and help you find the problems. In the automotive world this activity is not only rare, it runs contrary to the cash spent on dressing future cars in swirly vinyl. The Prius plug-in is different. Toyota built 600 demonstrators and sent them to large corporations, Zipcar fleets and, of course the press. Even TTAC was allowed to drive one for a week. What does that have to do with the final product? And how does it stack up against the Volt, Plug-in Fusion and the 2013 Accord Plug-in? Let’s find out.

Starting in March, the Chevrolet Volt will be eligible to use the HOV lane on California highways. The catch? You have to buy a new Volt to use the carpool lane.

CARB has mandated that 15.4 percent of new vehicles sold in California by 2025 must be plug-in, electric or fuel cell powered. The new mandate was supported by major OEMs and could mean as many as 1.4 million zero-emissions vehicles (as well as plug-in cars) on California roads by 2025.

I am a mechanical engineering student looking to learn how to work on cars.

My friend has given me the opportunity to take his 1988 Mazda B2200 extra-cab 5-speed. When I drove it, I saw why. The catalytic converter has broken off, and apparently pieces of it are in the exhaust. Would it be possible to just replace the catalytic converter, or should I replace the whole exhaust?

The WSJ [sub] reports

California regulators want zero-emission vehicles—those that don’t run on petroleum—to comprise up to 5.5% of new-car sales in the state, or roughly 81,300, in 2018. The target would rise annually to 14%, or more than 227,600, by 2025…

Tom Cackette, chief deputy executive officer of the California Air Resources Board, says his agency’s goal is to test whether electric cars can become mainstream vehicles, or wind up serving a “niche” market. Mr. Cackette said the state is investing in charging stations and other infrastructure, and he pointed to the sales of new plug-ins on the market to show that there’s a demand for the vehicles. He said he believes the California targets are feasible.

“That is a question we’ll only find out by trying,” he said. “I think [car companies] are making a pretty big investment in these vehicles, and they wouldn’t be doing that if they didn’t think there was a market there.”

Industry lobby groups are pushing California to roll the ZEV mandate into the forthcoming national CAFE standard. Small automakers like Mazda complain that placing a California ZEV mandate on top of national emissions standards would create a “costly burden…in light of the uncertain marketplace and infrastructure for electric vehicles.” And since CARB is leading the federal government by the ear towards a national standard anyway, it could simply push for a higher CAFE rate, which would at least allow firms the flexibility to comply on their own terms. Adding a major ZEV mandate won’t fundamentally change the national standard, but it absolutely will force automakers to spend huge amounts of money to develop a kind of vehicle that has major shortcomings, is only as green as local electricity generation, and has yet to prove itself with consumers. Whatever you think of emissions standards increases, it should be clear that consumers should determine what mix of technologies can best serve their needs while lowering fuel consumption and pollution.

California, the perennial thorn in the side of the EPA’s emissions-regulation scheme, has bowed to federal pressure and will wait until September of this year to release its 2017-2025 Model Year emissions standard proposal, by which time the EPA will be ready to announce its own national scheme. Prior to today’s announcement, California’s Air Resources Board (CARB) had “announced its intention” to release its proposal in March, a move which had automakers scrambling to complain to congress of the apparent lack of unity on emissions standards. GM and Chrysler even endured a (somewhat predictable) Naderite drubbing in the WaPo in order to to join the howls against the emerging “patchwork of state and national standards!”

Luckily for the automakers, CARB was willing to play ball. Per the WSJ:

Stanley Young, a spokesman for the California Air Resources Board, said the state agreed to the White House’s timetable after being assured the new fuel-economy targets would be based on studies currently being done on the feasibility of the proposed 62-mpg [by 2025] standard.

The studies are examining the technological and financial ramifications of the proposed standard, he said.

“We’re looking forward to seeing the results of the final data from the engineering studies,” Mr. Young said. He added that the board has always cooperated with the EPA and DOT and plans to continue to do so.

Then why stir up the pot by telling the world that you’ll create a de facto standard while the EPA is still looking at the engineering studies? If CARB was looking for ways to add to its resume of ill-advised overreaches, it succeeded admirably. If, on the other hand, it wanted to be seen as the lead partner in a national standard, it would have agreed to a joint announcement in the first place. Regardless of where the standards are set, surely even CARB understands that a truly national standard is the single most important achievement to be won in this process. Oh, and “making sure all the evidence was duly reviewed before ruling” should probably be the second most important.

With Chevy’s Volt priced at an eye-popping $41k before tax breaks, those tax breaks are now more important than ever. The first 200k Volts will qualify for up to $7,500 in federal credits, but Chevrolet had to be hoping for state incentives on top of the federal credit, especially in the key launch state of California. For a number of reasons though, the Volt doesn’t meet California’s requirements for Advanced Technology-Partial Zero Emissions Vehicles, and will lose out on a $5,000 tax credit that’s available to its cheaper competitor, the Nissan Leaf. As a result, the Leaf will cost Californians who qualify for both full credits about $20k, while the Volt will cost about $33,500. Moreover, the Leaf will have full access to California’s High Occupancy Vehicle lanes while the Volt will not, unless a pending bill before California’s state Senate passes. Together, these developments represent a serious advantage for the Leaf over the Volt in what is almost certain to be the world’s largest market for electric cars in the short-to-medium term. So how did GM let this happen?

Remember how the California Air Resources Board was contemplating banning black cars because air conditioning uses so much C02 (or not)? Well, the madness is over, as The Detroit News reports that California’s proposed “Cool Car” rules are dead. What killed them (besides common sense and the laws of diminishing returns)? Law enforcement, for one, which warned that (Read More…)

The Detroit Free Press reports that a recent filing by the California Air Resources Board [Full filing in PDF format here] threatens that a rapid ramp-up to the proposed 35.5 mpg 2016 standard and a reduction in zero-emission vehicle credits are necessary “to ensure California’s continued support.” CARB spokesman Stanley Young explains that “what we wanted to do is convey the level of importance for these two issues,” and that it’s “too early” to say whether California will withdraw from its compromise with the Obama administration. Still, the threat of a California withdrawal should be enough to get some attention in Washington, as Obama adviser David Axelrod has called the emissions compromise one of the administration’s top accomplishments of 2009.
