Porsche Cayenne GTS, base models revealed ahead of LA

Porsche unveiled a slew of refreshed Cayennes just a few months ago, but the base model (right) and high-performance GTS trim (above) were conspicuously absent from that list. There's no more reason to wonder about them, though, because the German brand plans to unveil both at the upcoming Los Angeles Auto Show on November 19.
Sitting below the Turbo in the lineup, the latest GTS still offers plenty of performance. It drops the previous version's naturally aspirated V8 in favor of a tuned version of the twin-turbo 3.6-liter V6 from the Cayenne S for some added oomph. The tweaks bring power up to 440 horsepower and 445 pound-feet of torque, which is enough to rocket the model to 62 miles per hour in an estimated 5.2 seconds. The bump also equates to 20 hp and 39 lb-ft more than the current S and more importantly 20 hp and 62 lb-ft more than the previous GTS, according to Porsche.
In addition to the extra muscle, Porsche also decks the GTS out with some added features. It comes with a standard sport exhaust and Porsche Active Suspension Management system with an air suspension lets the chassis sit about three-quarters of an inch lower (20 millimeters). To bring things to a halt, the high-performance models also takes its brakes from the Turbo model.

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.

Watch Porsche's 918 Spyder break a sweat while hot weather testing

With five months left until the 2015 Porsche 918 Spyder enters production, Porsche engineers are still putting the hybrid sports coupe through a battery of last-minute tests. To give us new reasons to ogle over the car - as if we needed any more - Porsche has released a short video showing the 918 Spyder undergoing shakedown tests in the hot Nevada desert. And you can't drive through Nevada without visiting Vegas, too, right?
Although there's really nothing new to see in this video, it's still fun to watch as Porsche approaches one million test miles logged on this exciting new high-performance model. One interesting part (at around the 0:37 mark) shows the car taking off under electric power and then transitioning to engine power, which results in a mix of whirs and growls as the 918 Spyder switches from a 127-horsepower electric vehicle to an 887-hp hybrid supercar. Scroll down to watch - and hear - Porsche's latest creation in motion.
