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.

Mercedes may be working on a new electric car dubbed 'Ecoluxe'

Automobile has a lengthy piece this month on how the four German mass-market luxury manufacturers each plan to go after Tesla with their own electric vehicles. It was written by Georg Kacher, the magazine's European bureau chief, and the English version came a month after he wrote the German-language original for Autobild. Tesla isn't exactly a threat to the Germans, but, according to the report, the Model S is planting the right kinds of seeds in niches that are important to the luxury players. The thinking is that - in addition to needed electric vehicles anyway for stricter US regulations - it's better to start designing the machinery now. The article posited Porsche's attack would rest on the coming Panamera platform, but a big hurdle would be battery placement. Unable to find one large space for a lithium-ion pack, engineers would instead put batteries everywhere they could, for a supposed tally of some "108 battery pouches" throughout the body. A few days after the Automobile piece, however, Porsche publicly said it had no intention of challenging the Model S, because the enthusiastic driving the brand is known for doesn't jive with useful range. In Kacher's retelling, Mercedes' plans are even more ambitious, supposedly taking aim at the Model S and the coming Model X. It would do this with an investment in excess of $2 billion in a program called "Ecoluxe" – Mercedes has no brand division akin to BMW's i and Audi's e-tron. The new brand would create a four-strong family of bespoke electric vehicles: a smaller platform with a wheelbase around 106 inches and a larger one with a wheelbase around 118 inches. In addition, the range would have "provisions for rear-wheel drive, all-wheel drive, and rear-wheel steering." The numbers are impressive: seating for seven in the larger vehicles, both longer than 16 feet, front and rear storage areas, ratings of up to 610 horsepower and production capacity of 80,000 units per year. When would we see such creatures? Perhaps as soon as 2019. We do know that if Tesla can knock the Model X over the outfield fence, automakers are going to have to do something. We don't know what the chances are that Ecoluxe is Mercedes' first move - but such a plan could help explain the weird Mercedes concept spied in October.

2014 Porsche Panamera S E-Hybrid is one mean green machine

The entire Porsche Panamera lineup gets a refresh for the 2014 model year, and new additions to the range include two long-wheelbase models and this E-Hybrid fuel-sipper that makes its debut here at the Shanghai Motor Show. And, well, we say "fuel-sipper lightly."
Porsche has packed its hybrid Panamera with 416 horsepower and 435 pound-feet of torque, and that certainly makes for one quick sedan-hatchback-thing. Hitting 60 miles per hour will reportedly take just 5.2 seconds, on its way to a top speed of 167 mph. And while Porsche hasn't revealed specific powertrain details, the company says that the S E-Hybrid "improves upon the concept offered by the previous Panamera S Hybrid with a more powerful electric motor," which leads us to believe that the supercharged 3.0-liter V6 engine at the heart of it all still remains intact.
Fuel economy numbers (or estimates) have not been released as of this writing, but we expect to have that information closer to the car's on-sale date later this year. As for the new battery system, Porsche says that when plugged into a 240-volt charging station, it can be fully charged in just two and a half hours. When topped off, the Panamera S E-Hybrid should have an electric driving range of around 20 miles at speeds up to 84 mph, though, obviously, not at the same time.
