Porsche accused of using steering inputs to cheat on emissions tests

Last week, the German transport authority KBA announced it was investigating Porsche and Audi for cheating on emissions tests. Wirtschaftswoche, a German economic publication, says the KBA's investigation focuses on a system that uses steering inputs to determine whether or not the car is being tested. While Audi has recalled 24,000 models, Automotive News reports that currently Porsche denies any wrongdoing. According to KBA, if the affected cars measured a steering input of 15 degrees or more, they would emit excess nitrogen oxide emissions. It's important to note that this is different than Volkswagen diesel CO2 emissions. The cars broke European strict emissions standards, so it's unclear what impact this has on cars in the US. Audi has recalled the A7 and A8, though it's unclear which Porsche models the KBA is investigating. Fifteen degrees is a small amount of steering input. The wheel can move that much just to move around a pothole or bump in the road. Essentially, if you're driving, you're moving the wheel at least 15 degrees in one direction or the other. If these allegations turn out to be true, it's going to be another blow to Volkswagen, Audi, and Porsche. While public trust in Volkswagen is supremely low, for the most part, Porsche's image has remained fairly clean. NOx emissions don't have as big of a long-term effect as CO2, though they're still bad for humans.

Porsche Cayman gets a new face

We've already seen photos of the facelifted Porsche Boxster out testing, but we're now seeing these same changes making their way onto the hardtop Cayman coupe. Cosmetically, the next round of Porsche's smallest sports cars isn't vastly different, with redesigned headlamps, LED running lights (like its big brother, the 911), and new taillamps that actually aren't visible on the prototype seen here.
The big news for the updated Boxster/Cayman range is the long-rumored four-cylinder engine. Recent reports suggest we could see four-pots with displacements of 1.6, 2.0, or 2.5 liters, and with output ratings as high as 360 horsepower. Of course, these new four-cylinder mills would be both turbocharged and direct-injected.
It's unclear whether or not the six-cylinder engine range will also be updated when this new Cayman comes to market. In any case, we expect to see it bow in the relatively near future. Stay tuned.

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.
