2013 Porsche 911 RSR makes official debut

Porsche is ready to go racing in 2013, showing off a new 911 RSR today that is scheduled to compete in several endurance events this year. Based on the current 991 911, the new RSR will compete in the 2013 season of the World Endurance Championship and the 24 Hours of Le Mans. It will not, however, make an appearance in a North American racing series this year.
The 2013 version of the racecar has increased in wheelbase by some four inches, features a new wishbone front suspension in place of the last-generation's McPherson strut setup and boasts a new, lightweight six-speed racing gearbox. The engine, meanwhile, is an "optimized" version of last year's car, a 460-horsepower 4.0-liter boxer six-cylinder. Extensive use of carbon fiber and polycarbonate windows help the RSR shed weight, and Porsche has also balanced the weight more evenly with a lower center of gravity.
Porsche has thoughtfully dedicated some space to celebrate the 911's 50th Anniversary, with the number 50 clearly visible in the top-down view of the RSR, as well as along the doors. Scroll down to read the full Porsche press release, below.

Despite premium carmakers going downmarket, luxury auto sales stick at 10-11%

According to research conducted by global information company IHS Automotive, the leporine birthing of new models by luxury manufacturers over the past six years hasn't increased their market share in the US. Even as car sales reached 15.6 million units, IHS says what's happened instead is that luxury buyers are merely moving from one brand to another, moving from larger luxury vehicles into hot segments like compact luxury crossovers or leaving the market at the same rate as other buyers enter.
Whether broken out by makes or by segment, market share has rollercoastered inside a narrow band from 10.5 to 11.5 percent since "at least" 2008. Closer investigation reveals the shifting boundaries in the aspirational pond, with brands like Mercedes-Benz and Audi gaining territory as Lexus and Lincoln lost it, and Saab and Hummer were buried, dead, under it. One neat note is that Tesla has gone from a share of zip to .12 percent.
The subcompact and compact crossover segments show growth, with those little high-riders jumping from .3 percent to 1.16 percent of overall industry sales. Their rise, though, is concomitant with the decline of four other segments: compact and midsize cars and fullsize cars and SUVs. We think the next few years that will tell if the small-car expansion can overcome the large-car retraction, with a phalanx of smaller offerings like the CLA only recently hitting the market and others like the GLA, Macan and Q1 doing so in the near future.

Porsche Panamera Turbo S vs Ariel Atom Supercharged in unlikely drag battle

David versus Goliath battles are always an enticing proposition, because they offer the chance to watch scrappy underdogs take on their bigger rivals. Evo has set up just such a battle with its latest drag race between the minimalist Ariel Atom 3.5 Supercharged (Ariel Atom 3 pictured below) and the plush Porsche Panamera Turbo S.
The two cars couldn't be more different. The Atom personifies Lotus founder Colin Chapman's well-known axiom: "Simplify, then add lightness." Most of the car doesn't even have a body; it's just an exposed frame with a 310 horsepower supercharged Honda four-cylinder mounted behind the driver. On the other side, there's the Panamera Turbo S. In the latest version, it packs 570 hp and 553 pound-feet from its 4.8-liter twin-turbo V8 and it features all-wheel drive. Of course, all of that comes with a significant weight penalty.
Off the line, the differences are even more apparent. The Atom doesn't have any of the Porsche's technological wizardry, so launching it challenges the driver to build the revs and let out the clutch just right. The car screams like a banshee as it goes, though. The Porsche is the exact opposite. Its launch control system lets the driver hold down the brake, get on the throttle and accelerate away in just the right way.
