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.

The next Bentley Mulsanne could go all-electric

How many Bentleys are sold in China, anyway?* That's a question worth asking after the company said it will consider switching the powertrain of its uber-luxe sedan Mulsanne to all-electric from its current gas-guzzling V8 setup. Such a switch would be in the name of adhering to stricter greenhouse-gas emissions limits, especially in countries like China. Bentley executive Hans Holzgartner told Autocar that the company may soon have problems selling a V8-powered Mulsanne in China because government regulators are attempting to push for more zero-emissions vehicles to combat smog problems in the country's largest cities. Oddly, Holzgartner said an electric powertrain is "better suited" to heavier luxury cars than lighter sports cars because of an electric motor's smooth, instant delivery of torque. With the Mulsanne already priced north of $300,000 in the US, passing on the costs of such a huge battery pack will probably be less of an issue than for more typically-priced models. Of course, there would be a ton (almost literally) of battery cells involved. The Mulsanne tips the scales at almost 6,000 pounds, or almost twice the weight of a Nissan Leaf and about 25 percent more than a Tesla Model S. For those curious how the one-percenters live, take a look at Autoblog's recent drive of a Mulsanne Speed. Since this is just being studied at this point, it's possible the next Mulsanne could get a battery-electric or plug-in hybrid version for certain markets, while others would retain a gas engine or offer a choice. Assuming it keeps the gas option, the next Mulsanne will reportedly to switch to a twelve-cylinder engine, likely a version of the Volkswagen Group's W12. As for green cred, let's just say the Mulsanne's couldn't be much worse. Earlier this year, the Mulsanne showed up on the American Council for an Energy-Efficient Economy's (ACEEE) annual list of "meanest" vehicles when it came to environmental sustainability. The Bentley was rated the fourth-meanest vehicle sold in the US, following the Mercedes-Benz G65 AMG, the Chevrolet G2500 Express/GMC Savana, and the Mercedes-Benz G63 AMG. The EPA rates the Mulsanne's fuel efficiency at an absolutely gasoline-swilling 13 miles per gallon combined. * If you're curious, Bentley sold 1,615 cars in China last year.

Porsche says next Cayenne will be faster than Bentley Bentayga

Bentley and Porsche are both high-end marques under the same umbrella, and may even be collaborating on development of new models – but while they tend to take different approaches and go after different customers, that doesn't mean they can't share a bit of sibling rivalry. And that spirit of competition – even within the Volkswagen Group – looks to be coming to a head in the form of their upcoming luxury performance crossovers. For his part, Bentley CEO Wolfgang Durheimer promises that the brand's upcoming Bentayga sport-ute will (in its top spec with the W12 engine) be the fastest SUV on the market. But in speaking with Car and Driver, Wolfgang Hatz – who holds the Porsche R&D head office that Durheimer used to occupy – says the Bentley won't be king for long. Porsche just released the new Cayenne Turbo S in Detroit, touting it as the first SUV to crack the eight-minute barrier at the Nurburgring. And Hatz says that the next version will be even faster. "Our Cayenne is always very very quick. It is doing 300 km/h [186 mph]. I think if [Durheimer] is doing 2 to 3 km/h more, then why not? He's doing that with a 12-cylinder. Our car will be much quicker on the road." The next Cayenne is slated to use a new generation of engines, and according to Hatz, will benefit from the same (if not more) weight loss as the new Audi Q7 with which it will share its platform. That sounds like a winning combination to us. That is, at least, for fans of performance crossovers. For those who aren't, Porsche promises it won't be bolstering its lineup with any new ones. Apparently the Cayenne and the smaller Macan are enough. Nor will Zuffenhausen slot anything bigger than a V6 into the Macan, according to the report. While Porsche's baby crossover will surely continue to get faster with new iterations, the Cayenne will always remain the performance flagship of its SUV range.
