Post image for Update on Chevy Volt Hearing

As noted here last week, the sparks flew at a Jan. 25 House Oversight and Government Reform Committee hearing titled “The Volt Fire: What Did NHTSA Know and When Did They Know It?” Three witnesses testified: National Highway Traffic Safety Administration (NHTSA) Administrator David Strickland, General Motors (GM) CEO Daniel Akerson, and John German of the International Council on Clean Transportation. My earlier post was based on newspaper accounts of the hearing. Over the weekend, I watched the archived video of the proceeding and read the testimonies and Committee Staff Report. Here are the key facts and conclusions as I see them:

  • The Volt battery fire occurred on June 2, 2011 in the parking lot of a Wisconsin crash test facility. The car caught fire three weeks after the vehicle had been totaled, on May 12, in a side-pole collision. The fire caused an explosion that destroyed not only the Volt but three other vehicles. The blast hurled one of the Volt’s components (a strut) a distance of nearly 80 feet.
  • The fire was caused by the leaking of coolant into the Volt’s powerful 300-volt battery, which had been punctured by the crash.
  • NHTSA could have avoided the fire had it run down (“drained,” “depowered,” “discharged”) the battery after the crash. This raises obvious questions: Was NHTSA responsible for the fire? Was the agency’s six-month silence partly an attempt to hide regulatory incompetence?
  • The Volt is a safe car; consumers should not fear to drive it. Gasoline-powered vehicles are more likely than battery-powered vehicles to burn after a crash. The post-crash explosion from a damaged gas tank can occur in seconds as opposed to weeks. Electric vehicle batteries are harder to puncture than gas tanks. NHTSA tried and failed to replicate the fire by crashing other Volt test vehicles. To induce another battery fire, NHTSA had to impale the battery with a steel rod and rotate it in coolant with special laboratory equipment.
  • GM is retrofitting Volt batteries to make them stronger and more leak proof, and is updating safety protocols to ensure batteries are depowered after crashes.
  • NHTSA kept silent about the fire for six months, acknowledging it only after Bloomberg News broke the story on November 11, 2011.
  • GOP Committee members produced no smoking gun evidence of collusion to cover up the Volt battery fire, such as an email saying ‘We’ve got to keep this under wraps or it will depress Volt sales, jeopardize EPA’s fuel economy negotiations with automakers, and make President Obama look bad.’
  • Nonetheless, the Obama administration’s heavy investment (financial and political) in GM in general and the Volt in particular creates an undeniable conflict of interest.
  • NHTSA determined the cause of the fire in August 2011, yet waited until November 25 to advise emergency responders, salvage yard managers, and Volt owners how to avoid, and reduce the safety risks associated with, post-crash fires.
  • Administrator Strickland’s protestations to the contrary notwithstanding, it is difficult to explain the agency’s secretiveness apart from political considerations that should not influence NHTSA’s regulatory deliberations.

Recently on this site and at MasterResource.Org, I discussed the Obama Administration’s proposed rule to establish first-ever greenhouse gas (GHG) and fuel-economy standards for heavy duty (HD) vehicles. The rule, jointly proposed by the EPA and the National Highway Traffic Safety Administration (NHTSA), would set increasingly stringent GHG and fuel economy standards for HD vehicles manufactured during model years (MYs) 2014-2018. HD vehicles include “combination tractors” (semi-trucks), “vocational trucks” (dump trucks, delivery trucks, buses), large pickups and vans.

Do Consumers Undervalue Fuel Economy?

The agencies have long held that “consumers undervalue fuel economy,” as EPA puts it on p. 44413 of its July 2008 Advanced Notice of Proposed Rulemaking: Regulating Greenhouse Gases under the Clean Air Act).  Yes, EPA acknowledges, the addition of fuel saving technology increases the purchase price of a vehicle, but, the agency contends, “the lifetime discounted fuel savings will exceed the initial cost increase substantially” (ANPR, p. 44447).

EPA writes as if the only factors consumers need to weigh and balance when purchasing an automobile are the upfront purchase price and the lifetime fuel costs. Given that premise, consumers who do not spend more for a higher mpg-vehicle are short-sighted (“fuelish”). Like children, they either do not discern their own best interest or lack the self-discipline to pursue it. So the Nanny State must step in and restrict our choices for our own good. Such is the elistist pretension underpinning three-plus decades of fuel-economy regulation.

In reality, consumers are not two-dimensional beings trapped, like agency fuel-economy fetishists, within a two-factor decision framework. In addition to the tradeoff between upfront cost and long-term fuel expenditures, consumers also consider vehicle power, performance, utility, style, safety, comfort, and amenities. Some people, for example, are willing to pay more for gasoline in order to enjoy the panoramic views, cargo space, passenger space, off-road versatility, and towing capacity of a large SUV.

More importantly, when consumers purchase a car, they typically take into account costs that are completely unrelated to the vehicle itself. For example, Mrs. Smith may prefer a lower priced car because she needs more disposable income this year for new home-office equipment, for little Sallie’s music lessons, or for Bill Jr.’s orthodonture. Forcing her to spend more of her disposable income on a higher-mpg vehicle would not enhance her family’s welfare, even if she could recover the extra expense in five years. Each consumer’s welfare is subjective and involves a subtle weighing and balancing of many competing considerations. For EPA to claim that “consumers undervalue fuel economy” is tantamount to saying that Mrs. Smith “overvalues” music lessons.

Do Truckers Underinvest in Fuel Economy?

Okay, so the notion that consumers “undervalue” fuel economy is dubious. In their joint proposed rule, EPA and NHTSA do not claim that truckers undervalue fuel economy. That would not pass the laugh test. As the agencies acknowledge (p. 315), “Unlike in the light-duty vehicle market, the vast majority of vehicles in the medium- and heavy-duty truck market are purchased and operated by businesses with narrow profit margins, and for which fuel costs represent a substantial operating expense.” Indeed, for truckers, fuel is the single biggest operating expense.

Clearly, nobody has a keener incentive to reduce fuel expenditures than people who haul freight for a living.

Yet the agencies claim that truckers “underinvest” in fuel saving technology. According to their calculations, the proposed rule will compel the trucking industry to invest $7.7 billion in fuel-saving technologies (p. 36), which will cut fuel consumption by 500 million barrels, which will save truckers $28 billion (assuming a 7% discount rate) or $42 billion (assuming a 3% discount rate). In the agencies’ words (p. 315), “the application of fuel-saving technologies in response to the proposed standards would, on average, yield private returns to truck owners of 140% to 420%.”

Unexamined Hypothesis: Opportunity Cost of EPA Emission Control Standards

The agencies propose five “potential hypotheses” to explain why firms with narrow profit margins in a competitive industry where fuel is the chief operating expense are not seizing an opportunity to make billions in easy money. As discsussed in my MasterResource column, none of these explanations demonstrates a “market failure.” In fact, two of the hypotheses suggest that truckers are simply acting like prudent buyers (although, naturally, the agencies don’t put it that way). Specifically, truckers want to make purchasing decisions based on road-tested information, not just agency speculation. Prior to actual deployment of the technologies, nobody knows whether they will yield the promised fuel savings and how they will affect engine reliability and maintenance costs.

The Oak Ridge Laboratory publishes an annual Transportation Energy Data Book. The chapter on heavy vehicles (p. 5-2) reports that the fuel-economy of “single unit” trucks improved 2% annually during 1998-2008. No “underinvestment” there. In contrast, “combination tractor” (semi-truck) fuel economy declined 1.2% annually over that period (p. 5-3). Yet these are the long-haul guys who, according to EPA and NHTSA, will save 18 times as much on fuel as owners of vocational trucks once they comply with the proposed rule (p. 337).

I don’t know if prudent- buyer behavior accounts for the alleged investment “gap” or “energy paradox” (p. 315) in the semi-truck category, but the agencies should have at least mentioned one other obvious “hypothesis”: the opportunity cost of EPA’s emission control mandates.

Back in the year 2000, EPA adopted tough new emission control standards for HD vehicles.  EPA’s Regulatory Impact Analysis (RIA) estimated that the industry’s 11 major diesel manufacturers would have to make substantial commitments of time, money, and personnel to comply with the new standards:

We have therefore estimated that each of the 11 major diesel engine manufacturers will invest approximately $7 million per year on research and development over a period of five years to adapt their engine technology to the advanced emission control technologies described here. Seven million dollars represents the approximate cost for a team of more than 21 engineers and 28 technicians to carry out advanced engine research, including the cost for engine test cell time and prototype system fabrication. [RIA, Chapter V: Economic Impacts, p. V-20]

“In total,” EPA’s RIA continues, “we have estimated that the engine manufacturers will spend approximately $385 million on R&D.” Three hundred and eighty-five million dollars. Presumably, that could crowd out significant R&D on fuel saving technology. Every year for five years, an estimated 21 engineers and 28 technicians at each of 11 major diesel manufacturers would be working on emission control technology. They would likely work less (or not at all) on fuel-saving technology.

The RIA also estimated that, in the “near term” (MY 2007), the average semi would incur fixed, variable, and operating costs of $280, $2,946, $3,785, respectively (p. V-7). So in the near term, owners would have about $7,000 a year less per vehicle to spend on fuel saving technology. For perspective, EPA and NHTSA estimate that their proposed GHG/fuel economy standards will increase the cost of a “combination tractor” by $5,896 in MY 2014 (p. 7-3). Presumably, some truckers who spent $7000-plus for mandated emission control technologies did not have $5,896 to spend for new fuel saving technology.
 
Finally, EPA’s year 2000 RIA says that the diesel particulate filter will “negatively impact fuel economy by approximately one percent” but that this will be “more than offset through optimization of the engine-PM trap-NOx adsorber system” (p. V-32). Whether this forecast turned out to be accurate or not, I do not know. 
 
What does seem clear is that EPA’s own rules may be responsible for the alleged “paradox” that the freight goods industry is not making cost-effective investments in fuel-saving technology.

Request for Information

Unfortunately, the latest information I have found on the industry-wide R&D costs and per-vehicle costs of EPA’s HD vehicle emission standards, and whether the associated technologies enhance or reduce HD vehicle fuel economy, is EPA’s year 2000 RIA, which offers projections rather than a retrospective, real-world, assessment. I would be grateful to anyone who can point me to later information.
