Ruf RGT 4.2 offers 518 hp of naturally aspirated power

Ruf has a reputation for building some fast interpretations of the Porsche 911, and the company's latest RGT 4.2 at the Geneva Motor Show provides an interesting point of comparison compared to the new GT3 RS that's debuting there. In terms of pure power, the Ruf wins out. The company crafts a flat six with 4.2-liters of displacement making 518 horsepower and 369 pound-feet of torque with a top speed of 200 miles per hour. In contrast, the latest GT3 RS gets 500 ponies and 338 lb-ft of twist from its direct-injected 4.0-liter mill. Depending on your desires, the RGT 4.2 might have the preferred gearbox too with its six-speed manual versus the Porsche's PDK. Styling is also going to come down to personal tastes between these two. The RGT 4.2 has an almost old-school racing look with its bolted-on fender flares, five-spoke wheels, thick carbon fiber rear wing and lower front air dam. Inside, there's also an integrated roll cage. The RS, on the contrary, appears thoroughly modern with its big fender intakes at the back, slashes just behind the front wheels, CFRP hood and magnesium roof. Check out Ruf's naturally aspirated monster on the Geneva show floor in the gallery, above. The RGT 4.2 maintains a long tradition of Ruf supercars with its outrageous driving performance. Unveiled in 2000, the first RGT was characterised by its powerful, torquey normally-aspirated flat-six engine. With a significantly reduced all-up weight and sports-oriented suspension system, the RGT was an extremely impressive driving machine.Now, in 2015, the RGT remains true its original concept, though its external appearance is clearly more athletic. The wheel arches are more bulbous and the front facade presents huge round air intakes for more effective cooling. The chassis is reinforced by RUF's hallmark Integrated Roll Cage (IRC). Propulsion is provided by its virile 4.2-litre six-cylinder, normally-aspirated engine, developing 525bhp and 500Nm of torque, featuring dry sump lubrication with external oil tank.

Porsche busts out new Boxster GTS and Cayman GTS

Baby 911. The poor man's Porsche. That's what they called the Boxster when it debuted some 20 years ago. They said the same of the first Cayman when it arrived a decade later, but they stopped saying it when the latest iterations hit the scene two years ago. That's because Zuffenhausen's entry-level models have long since stepped out of their big brother's shadow and into their own. And that's all the more true of the new Boxster GTS and Cayman GTS.
Based on the Boxster S and Cayman S, the new GTS models benefit from an enhanced 3.4-liter flat six that produces 330 horsepower and 273 pound-feet of torque in the roadster or 340 hp and 280 lb-ft in the coupe - representing an increase of 15 hp and 7 lb-ft in either model. Both also come with the Sport Chrono package as standard, along with adjustable suspension and 20-inch alloys, blacked out to match the dynamic headlight surrounds and other muted trim.
Those disappointed by the unavailability of a manual transmission in the fire-prone 911 GT3 will be pleased to note that a six-speed manual comes standard, but those enamored of letting a pair of clutches shift themselves seamlessly will want to spring for the optional seven-speed DCT. So equipped and with launch control engaged, the Boxster GTS will rocket from a standstill to 62 miles per hour in 4.7 seconds, while the incrementally lighter, more powerful Cayman will hit it in 4.6. Either way you're looking at a third of a second quicker than the Boxster/Cayman S. There's also a 20-millimeter lowered suspension on offer for track-day enthusiasts.

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.
