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 resurrects V8-powered 911 prototype from the Eighties

These days, we take it for granted that the Porsche 911 uses a flat-six engine. That's because every version of the iconic rear-engined sports car has had one. Right? Well, for the most part. There was the 912 that joined the original in the late Sixties with a flat-four. And in the mid-Eighties, Porsche toyed around with the idea of a V8-powered 911.
After the first-generation 911 had been in production for over two decades, Porsche began development of its successor, the 964, in the 1980s. And one of its ideas was to use a V8 engine. So it took a 964, borrowed a V8 from Audi, gave it the rear bodywork from a 959 and dubbed it the 965.
The idea was to create a more affordable successor to the 959 that included its advanced all-wheel drive system and active suspension. The Audi V8 would have been replaced with one of Porsche's own design - possibly based on the it had built for Indy racing - but Dr. Ulrich Bez (who was then head of Porsche R&D long before taking the reins at Aston Martin) ultimately killed the project.

Porsche releases new images of LMP1 racecar

Porsche has released another batch of images of its LMP1 competitor preparing for its debut season in 2014. This isn't the first we've seen of the new car, as June saw four images of the new racer undergoing testing. Where those images looked merely like someone taking pics during the test, the 11 new images seen above have all the hallmarks of highly polished PR shots.
That aside, the camo-covered cars still provide another look at what the new LMP1 car will look like when it arrives next season. The taillights follow the example set by Audi, by vertically mounting ultra-thin LEDs on the tips of the rear wing, while the LED headlights sport the four-prong look that Porsche has been pushing of late. Besides those two items, its difficult to make out many details due to the amount of camo.
Porsche's LMP1 effort will be focused on the FIA World Endurance Championship, which will see the revered brand return to the top flights of the 24 Hours Of Le Mans with F1 ace Mark Webber behind the wheel. As we've mentioned before, the German brand has set up a dedicated microsite that will cover its newest racer's progress.
