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 911 GT3 RS revealed in patent photos

Porsche has been taking its time developing the most hardcore 911 models for the latest 991 chassis. While the GT3 has been on the market for a little while, it suffered from some teething issues. The 911 GT3 RS is certainly on the radar since being spotted testing, but it's always better to get a look at a new car without all of the camo to hide the coolest parts. Thankfully, Car in the UK has some patent photos of the RS ahead of its debut, and they show off one mean-looking 911.
The first thing that you notice about the RS is that Porsche clearly isn't afraid to rework the latest 911's shape for its track-focused version. Each piece is slightly resculpted to squeeze the most out of it. Up front, the air dam has the same shape to the earlier photos. They also both highlight the upcoming model's tiny air inlet at the tip of the hood, the massive intakes in the rear fenders and general design of the rear wing with a ducktail underneath. The bubbled roof is much clearer here, where it was disguised in spy shots. You can also spot the slashing fender gills behind the front wheels that are a completely new feature.
The GT3 RS is the ultimate naturally aspirated 911 for the street, but according to Car, Porsche aims to take that even farther with the latest model. If these are the looks, then it's working. Unfortunately, the new version's powerplant remains a mystery. Though, given all the changes to the bodywork, the engine is almost surely getting tweaked over the 475-horsepower GT3. The RS is rumored to hit the road and be screaming down the track in 2015.

Porsche rolls out new 919 Hybrid at racing gala

That Porsche is returning to Le Mans next year with a top-tier LMP1 entry is no news - we've known that for some time. We've even seen pictures of the car in question undergoing testing at various racetracks across Europe, been told who'll be driving it and given some basic parameters of what will make it go. We just haven't known what to call it, but now we do.
In detailing its full endurance racing program for next year at its Night of Champions in Weissach, Porsche has revealed that its new LMP1 racecar will be called the 919 Hybrid. So, something like the 918 Spyder, only one faster. With a four-cylinder engine and a pair of electric motors, the 919 Hybrid will be taking on the top class at Le Mans next year, with a compelling roster of drivers on the docket: along with Mark Webber, Timo Bernhard, Romain Dumas and Neel Jani, Porsche has assigned its works driver Marc Lieb and F1 test driver Brendon Hartley to the effort. But that's not all Porsche has in store.
The factory is also supporting teams that will campaign the 911 RSR in the FIA World Endurance Championship as well as the United SportsCar Championship here in the US, taking Porsche off the pit wall and right in the race seat for next year as part of a comprehensive new racing program, details of which you can read in the press release below.
