2017 Porsche 911 Carrera experienced from the passenger seat

Autoblog joins Porsche for Rennsport Reunion V at Mazda Raceway Laguna Seca, the fifth international gathering of all things Porsche. If you've ever had a picture of a Porsche on your wall or dreamed of owning a certain model, either that very car or one just like it is here. Watching three 917 racers blaze over the rise at the front straight and down into turn one can make a viewer think, "So this is how Steve McQueen felt..." It was a modern Porsche that delivered one of the highlights of the first day, though: we rode shotgun for three hot laps of the track in the new turbocharged 991.2-series 911 Carrera S, with Thomas Krickelberg, director of powertrain for the 911 model line, our pilot. We cornered him and August Achleitner, vice president of the 911 product line, for a few questions about the changes. What do you call the standard 911 now that it has turbocharged engines? Carrera. If you're wondering what to call the standard 911 now that they have turbocharged engines, the answer is: Carrera. Krickelberg said, "In-house we call them 'little turbo' and 'big turbo,'" but the Carrera is a model line within the 911 model line, the big boy 911 Turbo is a second model line within the 911 family. One will continue to be called Carrera, the other simply Turbo. The move to turbocharging came to serve the twin kings of performance and fuel economy, but engineers played around with numerous configurations. A non-turbo engine displacing about 4.0 liters – that's as big as the 9A1 engine block can go – was considered, but that setup couldn't deliver the desired fuel efficiency. Krickelberg said engineers considered a small-displacement block of around 2.0 liters, but that was abandoned because "takeoff behavior was worse" because the turbo was called upon to do too much of the heavy performance living. Krickelberg added, "Not only that, but there was a too big a gap between real-world fuel economy and homologation fuel economy." Base Carrera and the Carrera S models haven't used the same engine displacement since the 996 series departed at the end of 2004. Achleitner said, "We found 3.0 liters is the best solution to get the best mix of fuel and air in combustion chamber - it offered the best geometry, bore and stroke, and the size of the walls.

Automakers agree to clean up diesels to avoid ban in German cities

BERLIN -- Auto industry officials and politicians in Germany have agreed to clean up diesel vehicles through software updates as part of a rescue plan for avoiding diesel bans in cities, industry and government sources said on Friday. The costs of the rescue plan amount to under 2 billion ($2.33 billion) euros for cars in Germany, with the auto industry agreeing to shoulder the expense of about 100 euros per car, the sources said. After Volkswagen Group confessed to emissions-test cheating in 2015, the entire auto industry has come under scrutiny for producing nitrogen oxide emissions in diesel cars, which are blamed for causing respiratory disease. Audi, a division of Volkswagen Group, said it would update engine software on up to 850,000 diesel cars. The refit of six and eight cylinder engines will be free of charge for all customers, Audi said. The service will also be offered to Porsche- and Volkswagen- branded cars using the same six- and eight-cylinder engines, Audi said. Earlier this week, Porsche's CEO was quoted as saying the brand may abandon diesel engines as its electric cars go to market, and Mercedes announced a plan similar to Audi's, in which it will recall 3 million diesel cars in Germany for a $255 million engine software fix. Diesel cars from all domestic and foreign car brands that conform to the latest emissions standards, Euro-6 and Euro-5, will be updated, the sources said. The plan is set to be presented at the beginning of August. With the software updates, the auto industry is able to cut nitrogen oxide pollution by about 20 percent, the sources said. A committee will be set up to measure the impact of updating diesel cars on individual communities and cities, with a view to averting bans of diesel cars, the sources said. Auto industry executives and German Transport Minister Alexander Dobrindt are due to discuss diesel pollution at a summit on Aug. 2.

Porsche patent sketches show removable headrest wind deflector

While driving around in a convertible might seem glamorous, ask anyone with long hair and they'll likely tell you how it really is: the wind buffets, your hair goes everywhere and it's anything but glamorous. That's why you see so many convertibles driving with their tops up, their windows up or wind deflectors in place. But Porsche is apparently preparing to kick it up to the next level.
These patent drawings have leaked out, demonstrating what appears to be some new kind of wind-deflecting device being developed by Porsche. The mechanism is apparently fitted to the headrest itself and designed to keep the wind buffeting specifically around the head down to a minimum while allowing the car's occupants to enjoy the top-down driving experience.
No word on when it might hit the market, but we won't be surprised to see this kind of device appear on a future version of the Boxster or 911 Cabriolet. But nowhere else: despite the apparent leak, the patent drawings suggest that Porsche will be keeping this technology proprietary. Whether sister brands like Volkswagen, Bentley or Lamborghini will get their hands on it remains to be seen.
