There’s a lot to like about the new GT3 RS including the fact that it is fitted with the largest engine ever to be mounted on a factory-approved 911; a 4.0-liter naturally aspirated flat-six unit that develops 500 horsepower at 8,250 rpm, 50 horses more than the standard GT3 RS. It is also the most powerful 911 naturally aspirated engine with 125 horsepower per liter. The engine carries the crankshaft from the 911 GT3 RSR racing car, while the forged pistons' connecting rods are made from titanium.

The ad is made up of four short fragments called ‘Snowmobile’, ‘Pickup Truck’, ‘Getaway Car’ and ‘School Bus' that show a 911 Carrera 4S, a Cayman, a 911 Carrera GTS and a 911 Turbo involved in everyday activities like shopping or picking up the kids from school. As a bonus, Porsche released a fifth fragment that didn't make it to the 30-second ad, called ‘Pet Carrier’. Take a look at the videos after the jump.

Other upgrades include ceramic brakes, 19-inch forged alloy wheels wrapped in 245/35 tires at the front and 325/30 at the back, an aero kit and an adjustable suspension. RUF also reduced the weight of the 911 Turbo through the use of exotic materials such as the carbon fiber wings, front luggage cover and bucker seats. The price of the Rt 12 R is set at €279,000 or about US$386,400 at today's exchange rates.

We already know that Porsche plans to debut a new model at the rapidly approaching North American International Auto Show (NAIAS) in Detroit next week, but the problem is that the German sports car maker is keeping its cards close to its chest about the type of vehicle it will unveil.

Adding to the many rumors already circulating on the internet, Bloomberg today reported that the model in question will be a racing coupe version of the 918 Spyder hybrid concept that was first shown at last year's Geneva Show.

Capable of 620 hp and 700 Nm (516 lb-ft) of torque, the 911 GT2 RS is the most powerful road-going Porsche ever built. It accelerates from standstill to 100 km/h (62 mph) in just 3.5 seconds and hits the 200 km/h (124 mph) mark in a staggering 9.8 seconds. Clearly, you need some impressive skills to drive pace the GT2 RS through a twisty circuit, but for now, you can enjoy Mr. Robertson at work in the video after the break.

Stuttgart's team of engineers started off by eliminating any unnecessary items for purists such as the air conditioning, audio system and complex door handles -owners will have to do with simple door pulls on this German baby. Porsche says more savings were achieved through the use of lightweight components including the carbon fiber bucket seats and the lightest 19 inch wheels offered by the company weighing in at less than 40kg / 80 lbs.

Available as both a coupe and convertible, the 408-horse / 310 lb-ft GTS is like a top-range naturally-aspirated model for everyday use; after all, the 435-horse GT3 isn't really a car for child-rearing families.

The car's power bump is the result of "a special resonance intake manifold [in which] six vacuum-controlled tuning flaps switch between power- and torque-optimized geometry, whereas in a Carrera S power unit there is only one tuning flap." Sounds like hocus pocus to me.

A spiritual successor to the 959 and Carrera GT models, the 918 Spyder sports a mid-mounted 500HP 3.4 liter V8 gasoline engine and a pair of electric motors located on the front and rear axle producing a combined 218-horsepower, for a total system output of 718HP.

It uses a high tech chassis bonded together with a special adhesive tape coated in polyethylene while the body is finger-made from exotic lightweight materials such as thin sheets of paperboard covered in a space-age aluminum foil that serves various purposes.

In this case, power is provided by a left-to-mid-mounted human-boxer unit capable of delivering a yawn-inspiring 1 fhp (foot horsepower) when fully fed, relaxed and emotionally happy.

Did we mention that it's also the fastest and most powerful road-going sports car ever built in the history of Porsche and that it turns the Nürburgring race track in just 7 minutes and 18 seconds or four seconds faster than the Dodge Viper ACR?

But let's take it from the start. The crown jewel of the 997 lineup is powered by a 3.6-liter six-cylinder boxer engine boosted by two turbochargers with variable turbine geometry that churns out 620HP and 700Nm or 516 lb-ft of peak torque. It drives the rear wheels through a six-speed manual gearbox.
