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.

2014 Porsche Panamera S E-Hybrid is one mean green machine

The entire Porsche Panamera lineup gets a refresh for the 2014 model year, and new additions to the range include two long-wheelbase models and this E-Hybrid fuel-sipper that makes its debut here at the Shanghai Motor Show. And, well, we say "fuel-sipper lightly."
Porsche has packed its hybrid Panamera with 416 horsepower and 435 pound-feet of torque, and that certainly makes for one quick sedan-hatchback-thing. Hitting 60 miles per hour will reportedly take just 5.2 seconds, on its way to a top speed of 167 mph. And while Porsche hasn't revealed specific powertrain details, the company says that the S E-Hybrid "improves upon the concept offered by the previous Panamera S Hybrid with a more powerful electric motor," which leads us to believe that the supercharged 3.0-liter V6 engine at the heart of it all still remains intact.
Fuel economy numbers (or estimates) have not been released as of this writing, but we expect to have that information closer to the car's on-sale date later this year. As for the new battery system, Porsche says that when plugged into a 240-volt charging station, it can be fully charged in just two and a half hours. When topped off, the Panamera S E-Hybrid should have an electric driving range of around 20 miles at speeds up to 84 mph, though, obviously, not at the same time.

2017 Porsche 911 Carrera First Drive [w/video]

The second seismic shift in the history of the Porsche 911 is happening as you read this. The first came in the late 1990s, when air cooling was thrown out and a more modern, water-cooled setup was put in place. People freaked out, and prices of air-cooled 911s are now skyrocketing. But I'll argue that this second major change is an even bigger deal: The free-breathing, naturally aspirated engine is gone, in its place a smaller, more powerful, turbocharged lump. But there's no need to panic. Purists be damned; "no replacement for displacement" shouters be silenced. This forced-induction heart beats beautifully in the 911's rump. I'm behind the wheel of a 2017 911 Carrera S coupe, stopped at the base of a winding mountain road on Tenerife, the largest of the Spanish-owned Canary Islands off the northwest coast of Africa. A nearly identical 911 is ahead of me, piloted by one of Porsche's test drivers. The road is closed. Hired spotters watch the corners. I'm about to run up the mountain at full charge, Porsche's expert leading the way. This forced-induction heart beats beautifully in the 911's rump. Behind me is the new engine: a 3.0-liter, twin-turbocharged flat-six. At idle, it still has that unmistakably Porsche, horizontally opposed hum. I've got 420 horsepower and 368 pound-feet of torque to work with, increases of 20 hp and 43 lb-ft compared to the old 3.8-liter, naturally aspirated six. If I launch it, I'll hit 60 miles per hour in under four seconds. Power is routed through the Porsche Doppelkupplung transmission – the best dual-clutch tranny in the business – and the fat, 305-section Pirelli PZero tires out back get all that thrust to the ground. There's a strong engine noise, complemented by the sound of the turbos sucking in air via the intakes just below the rear window. And then there's the exhaust. The standard Carrera comes with two large outlets and the Carrera S replaces those with quad pipes. But I've got the optional sport exhaust, not pictured on the car you see here, with two round outlets moved toward the center of the 911's hiney. Not only do they look way cooler, they're a treat for the ears. The Spanish may have decided to tunnel through many of Tenerife's mountainsides, but the pleasure of punching the throttle and letting the exhaust sing easily makes up for any loss of scenic views. The Carrera S' full 368 lb-ft is available right from 1,700 rpm, and there's no lag prior to arrival.
