Our hats are off to Porsche's 2014 911 Turbo Cabriolets

Porsche has just debuted its two latest decapitated rocket sleds today at the LA Auto Show, the new 911 Turbo Cabriolet and Turbo S Cabriolet, which share their coupe counterparts' 520-horsepower and 560-hp 3.8-liter twin-turbocharged flat-six engines. That kind of power ought separate a lot of hats (and toupees!) from heads.
The rear-engined Porsches put their power down through all four wheels, which allows them to launch from 0-60 in 3.3 seconds or less (the Turbo S Cab takes just 3.1 seconds), and both of them top out at 195 mph.
The 911 Turbo Cabriolet starts at $160,700, while the Turbo S Cabriolet can be had for a grand total of $193,900 (plus $950 for destination). Is the S model's 40 extra horsepower worth $33,200? We're not so sure, but we imagine Porsche won't have any trouble selling it.

Porsche Cayman GT4 speeds back into view

We're all familiar with the succession of numbers that follow the letters GT on a hard-core Porsche 911: the GT1 that was Stuttgart's Le Mans contender in the late 90s, the GT2 that packs turbochargers but without the Turbo's all-wheel drive and excess weight, and the naturally aspirated GT3 that's the enthusiast's choice. But a GT4? That's something new, and exactly what Porsche has in store.
Spied testing in Germany once again is the upcoming GT4 version of the Porsche Cayman, set to supersede the existing GTS and take the place of the previous Cayman R at the top of Porsche's junior sports car range. This latest batch of spy shots doesn't show us much more than the last crop, but gives us a much clearer view at what promises to be the most hardcore Cayman to date.
As you can see, the Cayman GT4 packs a much more aggressive aero kit and rolling stock than any version we've seen to date. It's got a lip spoiler, big air dam and GT3-style vent in front of the hood, deep air scoops along the flanks, a set of spindly alloys packing oversized brakes, a diffuser with twin central exhaust tips around back and a rear wing that's likely to be replaced with a sleeker unit before the GT4 reaches production.

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.
