'Latest production version' of Porsche 918 shown off on Twitter

Porsche posted a picture of what it is calling "the latest production version" of the 2015 Porsche 918 Spyder on Twitter. It looks like the gasoline-hybrid supercar is being driven sportively on some California back roads during Monterey Speed Week.
Whatever updates were made to this version aren't visual (except for the paint), as the one Chris Harris drove last spring and another seen hot-weather testing in Nevada both had production bodies. We presume the changes are relatively minor and more than skin deep - perhaps brake calibration, suspension tuning or tweaks to the powertrain - but Porsche didn't release any more information.
The 918 Spyder is Porsche's latest supercar, which will compete with the LaFerrari and the McLaren P1 hybrid supercars. The Porsche may be the underdog of the group when considering horsepower, acceleration, top speed and price, but the 887-horsepower brute has the most advanced hybrid drivetrain of the three.

Motor Trend holds World's Greatest Drag Race for the third time

As part of Motor Trend's Best Driver's Car competition, the buff book has held its third iteration of the World's Greatest Drag Race. With an airfield and a dozen of the world's finest performance cars at its disposal (oh, and a helicopter), the MT team did what any good group of enthusiasts would do, and tried to figure what car could cover a quarter mile the quickest. World's greatest drag race, indeed.
The contestants, as MT points out, cover a huge variety of engine types, drivelines, aspiration types and body styles, making for a genuinely varied and interesting field of competitors. Here's the full list of cars taking part.

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.
