Those who follow automotive technology know that modern diesel engines for passenger vehicles are clean, quiet, powerful and extremely fuel efficient. They would make an excellent addition to America’s arsenal of options for lowering greenhouse gas emissions and reducing demand for petroleum.
Consumers are beginning to move past diesel’s legacy perceptions, but that isn’t enough. Proponents of modern diesels say the technology deserves a fair hearing when regulators and legislators set policies intended to promote “green” technologies. Jeff Breneman, executive director of the recently formed U.S. Coalition for Advanced Diesel Cars in Washington, D.C., explains.
What is the coalition’s purpose?
We were founded by Bosch and BorgWarner at the beginning of 2009 specifically to make sure the voice of light-duty diesels is being heard when government policy is being written. Our coalition is supplier-driven, and our message to energy and environmental policymakers is to focus on the desired result and not try to pick the technology to get there. We’re pushing for technology-neutral policies.
Our focus is specifically to promote light-duty diesel cars, pickup trucks and SUVs whose engines meet federal tier 2 bin 5 standards. These are “clean” diesels that can be sold in all 50 states. As a group, they get 30% better fuel economy, emit 25% less carbon dioxide and deliver as much as 50% more torque than comparable gasoline-powered vehicles.
Why the push for diesels now?
We all remember the diesels of old. But they bear no comparison with today’s diesels. Advanced diesels became feasible in the U.S. in 2006 when low-sulfur fuel standards took effect. A year later the federal government put its tier 2 bin 5 emission standards into effect that made exhaust emissions from diesels and gasoline engines virtually the same.
The reality is that advanced diesels offer consumers an immediate improvement in fuel economy and a reduced carbon footprint without sacrificing any power. We’re not saying diesels are the only solution. They aren’t a silver bullet, and it’s important to note that our members supply technologies for hybrids and other environmentally friendly options. But if we’re going to reduce CO2, we need a portfolio of technologies. Diesels currently account for only about 3% of America’s overall vehicle fleet. We think it could be several times that level over the next five years.
How is your message being received by government policymakers?
These are very smart individuals, and they know their issues well. We don’t have to start with Diesel 101. They know the technology, and they know the options.
When we say we want technology-neutral policies and real-world reduction in petroleum usage and emissions, they agree. But then we point out policies that aren’t that way, such as incentives that are skewed toward a particular technology or fuel.
Does your effort also include consumer education?
There’s no question that consumers need more information to help them choose technologies that best suit their needs. But we think this is something that carmakers can do best.
It is important for consumers to understand the importance of choosing a fuel-saving technology that fits their driving patterns. For example, it doesn’t make sense to buy a hybrid SUV if your commute involves mostly highway driving. Hybrids are built primarily to help boost fuel economy in stop-and-go city traffic. On the highway, you’re just using your hybrid’s gasoline engine to lug around an extra battery and electric motor. For that type of driving, a diesel-powered SUV would probably be the better option.
What about the price of diesel fuel?
Currently we are seeing a degree of price stability at the pumps. Ultra-low-sulfur diesel is roughly the same as regular unleaded, and that’s in spite of a 33% tax penalty currently imposed on diesel fuel: 24.3 cents per gallon for diesel vs. 18.3 cents for gasoline. That penalty may change when Congress updates the transportation bill.
