Episode #344 of the Autoblog podcast is here, and this week, Dan Roth and Executive Editor Chris Paukert are joined by Doug DeMuro, author of Plays With Cars and prolific internet autowriting presence. Topics include the latest spy shots of the Porsche Macan, the 2014 Infiniti Q50, and the teaser images we've recently seen of a Subaru BRZ wearing STI badges. As always, we start with what's in the garage and finish up with some of your questions. For those of you who hung with us live on our UStream channel, thanks for taking the time.

Autoblog Podcast #344:

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.

Porsche 911 Aerodynamic prototype cheated the wind ahead of its time

You might think that sports cars would have the lowest drag coefficient of all cars. And yes, they do tend to be more slippery than, say, SUVs or convertibles, but the sleekest vehicles on the road tend to be EVs, hybrids and luxury sedans. Sports cars, on the other hand, have aerodynamically detrimental needs for downforce and additional engine cooling. Still, the Porsche 911 is better than most, and has only gotten more so over the years. Its relatively narrow track and compact form mean it has a smaller frontal area than some other sports cars, and the gradual sweeping back of its headlights and windshield have only augmented its capacity for cheating the wind.
This 911 prototype, however, is even more aerodynamic than most. It's based on a "G model" 911 from 1984, but employed such features as covered wheels, a new rear spoiler and a reprofiled front end to drop its drag coefficient from 0.40 to 0.27, making it as slippery as a modern sedan and better at cheating the wind than just about anything built up to that point, save for maybe the Tatra 77, Citroën SM or Tucker Torpedo.
Elements of this prototype ended up gradually making it into production Porsches for years to come, and you can clearly see early influences on the second-generation 964 and even on the 959. It's featured here as the latest installment in a video series on rare historic Porsches unearthed from the company archives, following previous clips that featured a rare V8-powered 911 and a mid-engined 911 prototype. Scope out the latest episode in the video below.
