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.

2015 Porsche 918 Spyder: Touring the factory

Willy Wonka granted just five lucky Golden Ticket holders access to his incredible chocolate factory, yet we consider ourselves just as fortunate, as Porsche invited us to be among the first of just four American journalists to see behind the closed doors of its 918 Spyder assembly plant in Zuffenhausen, Germany. Of course, there were no Oompa Loompas or flowing chocolate rivers, but the vast white hall tasked with producing only 918 examples of the automaker's limited-production flagship revealed details that make Wonka's Golden Egg sorting room seem rather mundane in comparison. Unlike a traditional automobile manufacturing plant, which often encompass all processes of making a vehicle (e.g., stamping steel panels, welding components and painting), the 918 Spyder is built in an assembly plant. This means that hundreds of already manufactured parts, each crafted by Porsche offsite suppliers, are brought under one roof to be assembled into a perfectly finished product that is much sweeter – and far more expensive – than any candy delicacy. Our tour guide was Michael Drolshagen, Porsche's Director of Production, Logistics and Quality - a walking encyclopedia when it comes to the engineering and assembly of the 918 Spyder. Drolshagen generously offered us unrestricted access to walk among the factory's 110 workers – and a couple-dozen vehicles in process – to photograph everything. This is a story best told with pictures, so we've put together a raft of our best images in a high-resolution gallery and captioned each with a detailed description.

2017 Porsche 911 Carrera First Drive [w/video]

The second seismic shift in the history of the Porsche 911 is happening as you read this. The first came in the late 1990s, when air cooling was thrown out and a more modern, water-cooled setup was put in place. People freaked out, and prices of air-cooled 911s are now skyrocketing. But I'll argue that this second major change is an even bigger deal: The free-breathing, naturally aspirated engine is gone, in its place a smaller, more powerful, turbocharged lump. But there's no need to panic. Purists be damned; "no replacement for displacement" shouters be silenced. This forced-induction heart beats beautifully in the 911's rump. I'm behind the wheel of a 2017 911 Carrera S coupe, stopped at the base of a winding mountain road on Tenerife, the largest of the Spanish-owned Canary Islands off the northwest coast of Africa. A nearly identical 911 is ahead of me, piloted by one of Porsche's test drivers. The road is closed. Hired spotters watch the corners. I'm about to run up the mountain at full charge, Porsche's expert leading the way. This forced-induction heart beats beautifully in the 911's rump. Behind me is the new engine: a 3.0-liter, twin-turbocharged flat-six. At idle, it still has that unmistakably Porsche, horizontally opposed hum. I've got 420 horsepower and 368 pound-feet of torque to work with, increases of 20 hp and 43 lb-ft compared to the old 3.8-liter, naturally aspirated six. If I launch it, I'll hit 60 miles per hour in under four seconds. Power is routed through the Porsche Doppelkupplung transmission – the best dual-clutch tranny in the business – and the fat, 305-section Pirelli PZero tires out back get all that thrust to the ground. There's a strong engine noise, complemented by the sound of the turbos sucking in air via the intakes just below the rear window. And then there's the exhaust. The standard Carrera comes with two large outlets and the Carrera S replaces those with quad pipes. But I've got the optional sport exhaust, not pictured on the car you see here, with two round outlets moved toward the center of the 911's hiney. Not only do they look way cooler, they're a treat for the ears. The Spanish may have decided to tunnel through many of Tenerife's mountainsides, but the pleasure of punching the throttle and letting the exhaust sing easily makes up for any loss of scenic views. The Carrera S' full 368 lb-ft is available right from 1,700 rpm, and there's no lag prior to arrival.
