Porsche testing four-cylinder Boxster at the N?rburgring

Porsche recently introduced a four-cylinder version of the new Macan for markets outside of North America, carrying Zuffenhausen's first four-pot since the 968 ended its production run the better part of two decades ago. But you can bet the compact crossover won't be the only Porsche to get the four banger before all's said and done. These spy shots, we're told, are evidence of just that.
Spotted undergoing testing at the Nürburgring (where else), this modified Boxster, our spy photographers tell us, sounds more like a four-cylinder engine than the flat six that's powered (in displacements ranging from 2.5 liters to 3.4) every version of the little roadster since its introduction in 1996, the year after the last four-cylinder Porsche ended production.
The test mule is also wearing modified wheel arches and aerodynamic aids under the bumpers, front and rear. Just what they're doing there we're not sure, but we'll probably find out sooner or later.

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.

Supercars for the win | Autoblog Podcast #515

Some days at Autoblog are better than others. And in this episode, we talk about those days. Specifically, the days where we get to drive supercars. Mike Austin, Greg Migliore, and Alex Kierstein join up in this episode to talk about driving the McLaren 720S, Ford GT, and Porsche 911 GT3. We also drove some less-super, but still notable cars that we talk about at the top of the show. And as always, we play the game Spend My Money where we get to tell readers what we'd do if we were them. We had a lot of fun with this one, we hope you enjoy listening to it. The rundown is below. Remember, if you have a car-related question you'd like us to answer or you want buying advice of your very own, send a message or a voice memo to podcast at autoblog dot com. (If you record audio of a question with your phone and get it to us, you could hear your very own voice on the podcast. Neat, right?) And if you have other questions or comments, please send those too.
