40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.

These are your top 10 worst-selling vehicles of 2012

Despite 2012 being the best year of auto sales this country has seen since 2007, not every vehicle got an equally large share of the sales pie. Some barely got a sliver, as evidenced by this year's list of the top 10 worst-selling vehicles of 2012. We've dug through sales data from every automaker to come up with this year's list and, like last year, we've set some parameters to ensure it includes legitimately bad-selling vehicles. The first parameter is a starting MSRP under $100,000, which automatically excludes what's parked in most one-percenters' garages. We're also excluding vehicles cancelled in 2012, even if they garnered sales through the end of the year while dealerships sold off remaining inventory. This includes models like the Mitsubishi Eclipse, Mercedes-Benz R-Class and last year's worst-seller, the Acura RL. Next, vehicles are considered as they are reported by the automaker, which means that, while sales of the Murano CrossCabriolet were probably low enough to make the list, because Nissan reports only one number for all Murano sales, it was excluded. Cadillac, however, reports sales of the Escalade EXT separately from the Escalade, hence its repeat appearance. Finally, there was the question of whether or not eligibility should be given to Suzuki vehicles, as the brand announced in November that it would end sales in the US as soon as its current inventory ran out. We decided Suzuki vehicles should be included as the brand was offering 2013 models at the time of the announcement, and as far as we can tell, inventory levels remained high enough to satisfy demand through the end of the year. Without further ado, below are the top 10 worst-selling vehicles of 2012. Top 10 Worst-Selling Vehicles of 2012 10. Volvo C30 MSRP: $25,500 Units Sold: 2,827 Last Year: – 9.

Delphi thrilled with results from autonomous car's cross-country trip

In the first trip across the United States ever made by an autonomous car, engineers from Delphi Automotive were surprised to learn that, in some cases, their vehicle behaved a lot like a human driver. "The car was scared of tractor trailers," said Jeff Owens, the company's chief technology officer. "The car edged to the left just a little bit when it would pass trucks, and that was an interesting observation." Engineers made hundreds of notes throughout the drive, as the autonomous car covered 3,400 miles through 15 states en route to a showcase near the New York Auto Show. Overall, company officials said the car performed better than anticipated in a variety of road and weather conditions. In the course of the cross-country drive, drivers actually controlled the car only for about 50 miles, and those cases were limited to on-and-off ramps and the occasional construction zone where lanes were not marked or only sporadically marked. The purpose of the trip was to glean information on how the autonomous car worked in a real-world environment. Google and others have tested autonomous cars and autonomous features in select real-world environments before, but Delphi's adventure was the first to trek into a test with such varied challenges over a nine-day trip that began near the Golden Gate Bridge on March 22. There are some things the engineers have already learned, like the fact the camera systems had the occasional blip when the sun-angle was low. And there are some things to still be learned, as they pour over three terrabytes worth of data from cameras, radar and lidar sensors in the weeks ahead. "It's going to take us a couple weeks to digest all this," Owens said. "But we had all the data from tests. It was time to put this on the road." Built into an Audi SQ5, the vehicle was striking, if only for the fact it looked like a normal car. Many other autonomous vehicles have quirky sensors atop the roof or other features that make them stand out as experiments. Delphi arranged this one to look as much like a normal car as possible, right down to stowing an army of computers under cargo mats, so the rear contained as much trunk space as the production model. If a fellow motorist didn't know where to look -- or take the time to notice the person in the driver's seat didn't have their hands on the wheel -- there was no reason to suspect this was anything other than a regular car.
