Porsche 911 GT2 RS vs. Mercedes SLS AMG Black in battle of who can shred more rubber

We might be looking at the end of an era in European performance models. Mercedes-Benz is doing away with the SLS in favor of a rumored smaller and cheaper SLC, and Porsche has said that a new 911 GT2 isn't necessarily a sure thing, which means another 911 GT2 RS is even farther away. In its latest video, Evo's Jethro Bovingdon pits the ultimate versions of these German sports coupes against each other and finds two of the fastest cars the magazine has ever lapped around its track.
In one corner, there is the Mercedes SLS AMG Black Series that sits as the pinnacle of the company's halo model. It relies on the classic setup of a V8 mounted in front powering the rear wheels. On the other side, there is the 911 GT2 RS with a turbocharged flat-six mounted at the back, spinning the rear wheels. It was conceived to be Porsche's ultimate expression of a turbocharged 911, and while it's a few years old, Bovingdon shows that it's up to the task of racing a more modern rival.
Both of these rear-wheel-drive monsters are more than capable of some fantastically smoky power-slides, but they also show how great the last generation of sports cars was. Scroll down to check out the video.

Porsche 991 vs. 930 Flatnose in 911 Turbo convertible faceoff

The Porsche 911 Turbo has a legacy of being a tough car to drive. With a ton of power set right over the rear wheels, its reputation is to lose control as soon as the driver stops concentrating. However, this isn't quite so true anymore. The modern ones are tamed through technology with things like hydraulically controlled engine mounts, not to mention all-wheel drive. In its latest video, Autocar tries to decide whether 25 years of progress really makes the turbo a better vehicle.
It's summer, so what better version to compare than the 911 Turbo Cabriolet? In one corner, Autocar has the latest and greatest 2014 version pumping out 513 horsepower and 486 pound-feet of torque with a seven-speed dual-clutch gearbox. Its challenger is a 1989 911 flatnose convertible sporting 326 hp and 347 lb-ft of torque. It's a truly rare car in the UK with only eight of them remaining on the roads in that region.
Granted, this test isn't so much a battle as it is a comparison. There's no question that the modern 911 would beat the classic in practically every objective category. What the video aims to find out is whether the flatnose is better in subjective measurements like its "feel." Scroll down to watch these two droptop Porsches square off.

Porsche Classic launching branded motor oil for air-cooled boxer engines

It's hard not to love the look of a classic Porsche. Whether it's the upside-down bathtub styling of the 356 or the gradual evolution of the 911, there is a little beauty in all of them. However, the older they get, the more that needs repaired to keep them on the road. Porsche Classic is helping out, though, by introducing its own brand of motor oil for the demands of the company's vintage, air-cooled engines.
Developed at the Porsche Development Centre in Weissach, Germany, Porsche Classic Motoroil comes in two weights - 20W-50 for the 356, 914 and 911 models up to the 2.7-liter G-Model and 10W-60 for 3.0-liters-and-up engines through the 993-chassis 911. The company claims that the air-cooled engines have different heat demands than traditional, water-cooled units, and this oil is made to meet those requirements.
According to Porsche, modern, synthetic oils are sometimes too effective when it comes to old engines. They are fantastic at sopping up debris, but those deposits are often holding archaic seals together. Suddenly removing them can cause leaks. The new oil is specifically designed to work with the old-fashioned materials found in its classics. The company also knows that most owners aren't driving their vintage cars everyday. So this formulation is more alkaline that normal to neutralize acids that they build up and corrode components.
