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.

Audi R8 LMX illuminates the City of Light with lasers

Hard as it may seem to believe, the Audi R8 has been around for the better part of a decade. But does that make us love it any less? Hardly, especially not when Audi keeps rolling out ever-more enticing versions like the one you see here.
Debuting at the Paris Motor Show, the new Audi R8 LMX is the most powerful version of the supercar we've seen yet, thanks to a 5.2-liter V10 engine tuned to deliver 570 metric horsepower. That's 562 by our count, making it ten horses more potent than the R8 GT, or 37 more than the standard ten-cylinder R8 5.2 FSI - enough to propel the LMX to 62 in 3.4 seconds.
That's not all that sets the LMX apart, however, as Audi has fit it with cutting-edge laser-beam headlights. It comes exclusively as a coupe in Ara Blue with carbon fiber trim, special wheels, red brake calipers and a black leather cockpit. Only 99 examples will be made, and with those laser headlights banned in the US, your best chance of seeing one is in the gallery of live images above.

US diesel model count to double for 2014?

While diesel cars are popular on most other continents, these less-complex alternative to hybrid-electric vehicles have yet to gain major traction in the US. As an increasing number of light cars and trucks start to offer these fuel-efficient engines, though, sales are expected to climb as well. While BMW, Mercedes-Benz and the Volkswagen Group (Volkswagen, Audi and Porsche) continue to lead the way, more non-German automakers like Mazda, Nissan, Chrysler and General Motors are starting to get serious about diesel in America.
TheDetroitBureau.com reports that the 2014 model year will see the number of diesel vehicles offered in the US double to about 40 nameplates, but the news gets even better for fans of these torquey and efficient powerplants. LMC Automotive has released data about future expectations of diesel cars in the US, and it predicts that sales should be very close to one million units in 2015 (up from an expected 600,000 units this year). By 2018, LMC's calculations suggest that sales will more than double from this year's expected totals accounting for almost 8 percent of new light-vehicle sales.
