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.

Porsche completes production of 918 Spyder

Porsche is closing another chapter in its history as production of the 918 Spyder has officially come to an end. The only remaining question is: what comes next? The 918 was the latest in a long line of flagship supercars from the German automaker, starting with the 904 Carrera GTS, continuing on through the 959, 911 GT1, and Carrera GT. Each was a technological game-changer for Porsche, just as the 918 Spyder will surely be remembered. With the hybrid roadster now zipping off into the annals of history, all eyes will be fixed on Zuffenhausen to see what it does next. And though it may not be much to go on, we've already begun seeing some hints at what that could be. Last week Porsche released a solitary teaser image showing its next-generation sports car, covered and parked alongside the Le Mans-winning 919 Hybrid LMP1. Just what's under the cover, Porsche isn't saying, and didn't respond to our repeated inquiries for comment. However the signs point towards a mid-engined supercar – not unlikely to pack a hybrid powertain once again – positioned closer to the likes of McLaren 650S and Ferrari 488 GTB than the outgoing 918 Spyder, which faced off against the McLaren P1 and LaFerrari. If that turns out to be the direction Porsche takes with its upcoming new supercar, as has long been anticipated, it would hardly be unprovoked. McLaren recently launched the 570S as part of its new Sport Series to take on the Porsche 911 Turbo, and Ferrari is once again rumored to be pursuing the same with a new Dino. While the specifics may remain cloudy for the time being, what is crystal clear is that things are about to get very interesting in the battle between Porsche and its rivals.

Today, the chequered flag marked the finish: after 21 months of production time, the final Porsche 918 Spyder came off the line in Stuttgart-Zuffenhausen according to schedule. But the legacy of this technology pioneer will reach far beyond its production time. Future generations of sports cars will benefit directly from innovations of the 918 Spyder. The 918 Spyder was systematically developed to be a performance hybrid with plug-in technology. The hybrid super sports concept car made its debut at the 2010 Geneva International Motor Show where it met with overwhelming approval.

2014 Porsche Panamera Turbo S is a 911 Turbo for the family man

In the event that the Porsche Panamera Turbo's 520 horsepower and 189-mile-per-hour top speed aren't enough to sate the appetite of the speed freak, Porsche has just given the auto show debut to the faster, more powerful Panamera Turbo S.
With 570 horsepower being pumped from a 4.8-liter, twin-turbocharged V8, the Panamera Turbo S promises even faster acceleration, hitting 60 mph in 3.6 seconds, a 0.3-second improvement over the standard Turbo. The top speed, meanwhile, climbs to 192 mph, which is kind of ridiculous for a car with four doors and a trunk.
Other enhancements that come with this Panamera's extra syllable include carbon-ceramic brakes and the entirety of Porsche's active chassis systems, including Porsche Dynamic Chassis Control and Porsche Active Suspension Management. The performance goodies come standard, but that doesn't mean the Panamera Turbo S is cheap.
