Would you pay more for a greener car?

Consumers won't pay more for cars that would meet new, stricter emissions standards.

That was the message sent last week by Susan Docherty, Western Region general manager of General Motors, as a handful of automotive journalists (including yours truly) sat scattered at a very large table in a private room in the back of one of Santa Monica's poshest hotel restaurants during a GM-sponsored holiday dinner.

The proclamation erupted out of a somewhat heated debate with one of the print journalists at the table, sparked in part by news that a U.S. District Judge had dismissed a lawsuit filed by automakers over a California law that would require car manufacturers to reduce new car emissions over the next several years.

The statement was especially curious coming from someone who had worked for one of the most expensive automotive brands in the U.S. Prior to her previous position, Docherty worked as head of marketing and sales for Hummer. According to her biography, her launch of the H3 increased Hummer's sales by more than 70 percent. If there are obviously plenty of people who will pay more than $30,000 for SUVs that get 13 miles per gallon in the city, why wouldn't there be a market for a $30,000 midsize car that gets 40 miles per gallon (or better)?

Some of us aren't so quick to underestimate the increasing savvy of the American consumer. While there are still people who will buy the biggest vehicles they can afford without regard to long-term consequences, the average car buyer is getting smarter. Even putting questions of social responsibility aside, basic economics tell us that the financial implication of buying a car goes far beyond the sticker price; it's about the overall cost of ownership. And we think you get that.

What do you think?

Tips for getting better gas mileage

by Laura Burstein
  • 9 comments

With all the talk of new, fuel-efficient vehicles, those of us who are still driving our regular old cars might feel left out. But there are still ways we can help save gas -- and money -- by making relatively simple adjustments to our cars and driving habits.

Change the air filter. The air filter is a crucial component to minimizing fuel use and maximizing horsepower. Bryan Gregory, director of consumer education for Advance Auto Parts, says it takes an engine about 10,000 gallons of air to combust one gallon of gas. So it makes sense, then, that the easier it is for the air to get through, the more efficiently the engine will run. Air filters should be replaced every 7,500 miles, or according to the manufacturer's recommendations.

Check tire pressure. We've talked about proper tire pressure before, but it's still worth mentioning. Gregory says that every pound per-square-inch that a tire is under-inflated results in a six-percent loss in fuel efficiency. Make sure your tires fall within the recommended psi, printed on the sidewall.

Reduce idling. Plan trips to avoid peak traffic times. Going to the drive-thru? Go a little early (or late) to avoid sitting in line. And skip the long warm-up period in the morning. With the exception of extreme cold, most cars and trucks need only 30 to 45 seconds to warm up.

Lighten up. Fuel mileage is reduced by one mile per gallon for every 200 pounds of extra weight. Get rid of extra tires (except for the spare), bike or ski racks that aren't being used, toys, and other equipment that could weigh your car down.

Don't tailgate. Stop-and-go driving wreaks havoc on gas mileage. Accelerate slowly in crawling traffic and keep some distance. Then coast up to a stop instead of punching on the brakes.

Squeeze, don't punch. Practice slow, steady starts by imagining an egg underneath the accelerator pedal. Gregory says racing legend Jackie Stewart used this technique on the track.

Use the right gas. Check the owner's manual for the proper octane rating for your car. Using a lower grade than recommended can gum up fuel lines, reducing efficiency and increasing engine wear.

Power system for refrigerator trucks aims to reduce diesel pollution

Refrigerator trucks may not be sexy, but they play a vital role in our day-to-day lives by carrying food and supplies from one part of the country to another. However, they also contribute a significant amount of pollution on our roads.

Aura Systems, a company based in El Segundo, Calif., on Wednesday introduced a mobile-power system that keeps produce cold by using electricity instead of diesel fuel.

Traditional refrigeration trucks use a separate diesel engine to drive the compressor that keeps the inside of the truck cold. The extra engine not only emits more pollutants, but is also extremely expensive to operate.

The first vehicle with the new system, the Oasis, is a midsize Isuzu refrigeration truck. The truck's cooling compressor is jump-started by a large power surge (the system can handle between 5 kilowatts and 8.5 kilowatts of power), and it is kept running by the truck's main engine. And although the system still relies on diesel to keep it going, Aura reps say the elimination of the second motor saves, on average, about $250 in fuel costs per month, per truck.

The Oasis is set be on display at the Worldwide Food Expo October 24 through 27 at McCormick Place in Chicago.

2008 smart cars ready to hit U.S.

2008 smart fortwo

Pricing is out for the new, admittedly odd-looking smart fortwo. The compact vehicle, manufactured by Mercedes, features a 1-liter, 3-cylinder engine that puts out a maximum of 71 horsepower. Cars are expected to ship the first quarter of 2008.

The base model starts at $11,590 and includes a 5-speed transmission that switches from automatic to manual mode with the touch of a button. The "passion coupe," which includes features found in more expensive luxury cars like a panorama roof, alloy wheels, paddle shifters and heated side mirrors, starts at $13,590. The convertible will be $16,590 and up, with an optional premium sound system that includes an in-dash MP3 compatible 6-CD changer. Smart claims its cabriolet will be the lowest priced convertible offered in the U.S.

Smart is hinging much of its sales on fuel efficiency numbers. The fortwos can achieve more than 40 miles per gallon under normal driving conditions.

Smart executives earlier this year hinted at plans to open several smart car dealerships across the country; many will be attached to Mercedes-Benz dealerships, much the way Mini Coopers are sold at dealerships alongside BMWs. The smart dealer network will be officially announced this fall. Smart cars are currently sold in 36 countries, and more than 800,000 smart fortwos have been sold since 1998.

Tiny gadget eases tire pressure worries

TiroGage air pressure gauge

California-based company Resource Manufacturing Inc. (RMI), along with Wika Instrument, the world's largest gauge manufacturer, are touting their new air pressure gauge as the answer to every lazy motorist's prayer.

The patented TiroGage, which is designed to be left on, attaches directly to the tire's valve stem. The pressure reading is displayed constantly on an outer lens, which allows drivers to check their tires with just a quick glance. Air can be added or released through the gauge itself, eliminating the need for external gauges or valve stem caps.

This is great news for those of us (your writer included) who procrastinate when it comes to checking the air pressure in our tires. The National Highway Traffic Safety Administration (NHTSA) recommends checking the air pressure on each tire a minimum of once a month. But how many of us do it? Maintaining proper air pressure is crucial for achieving optimal fuel economy, maximizing performance, increasing tire life and ensuring road safety.

RMI says the TiroGage is accurate within 3 percent (plus or minus) in tire temperatures between -40 and 150 degrees Fahrenheit. The body of the gauge is made of brass and the lens is made of Lexan, the same material used for bullet-proof windshields. The entire device weighs less than an ounce and has a diameter slightly larger than a U.S. quarter.

The TiroGage will initially be made for commercial trucks and large RVs and will be available later this month for $24.95 each. Gauges for passenger cars, motorcycles and bicycles are scheduled to roll off the assembly line sometime next year.
