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.

Audi A5 and S5 freshen up for 2017

UPDATE: A previous version of this story mischaracterized the 2017 S5's engine configuration. The article has been updated. Well, here's the new Audi A5 and S5. They look a lot like the old ones, but just a tiny bit better. In other words, the redesigned coupes received the same treatment as their four-door counterparts, the A4 and S4. While the German press materials mention both gas and diesel engines, we expect the A5 to carry on in the US with petrol power only. Like the current A5, a 2.0-liter, turbocharged four-cylinder will serve as the base engine, but will probably get a similar power bump as the A4 – Audi hasn't released official figures yet. The four-door had its base output bumped from 220 horsepower and 258 pound-feet of torque to 252 hp and 273 lb-ft of torque. The S5 is a more interesting proposition than the S4. Where the old S5's 3.0-liter, supercharged V6 produced 333 hp and 325 lb-ft of torque, the new, turbocharged, 3.0-liter six-cylinder pumps out 354 ponies, according to the global press materials. That figure, fans of the old 4.2-liter V8-powered S5 will note, is identical to the original S5 that came out for model-year 2008. Torque figures aren't available yet, but we'd bet on at least a small increase in torque. Still, the increase in power is good for a 4.7-second run to 62 miles per hour, a 0.2-second improvement over the current car's 0-60 time. Audi claims it will offer the A5 with both six-speed manuals and seven-speed dual-clutch transmissions, but we wouldn't be so sure about that stick here in the US. The only available gearbox on the A4 is a seven-speed S-Tronic – coupes are inherently more sporting than sedans, but we aren't sure that's justification for Audi to offer a manual-trans A5 here in the US. Audi only mentions an eight-speed automatic for the S5. So no, the German press materials aren't a good indicator of the US-market A5. What we can rely on, of course, are the official images. The original A5/S5 was a handsome car, but Audi's designers have done a swell job styling the 2017 model. It looks good, and is somehow even more refined than last year's car. Audi's new corporate grille works well on a coupe body, although the powerful creases in the hood might be a little too powerful. The tail is lovely, like a prettier A3. The bodies are better looking, but they're also lighter and more aerodynamic, too. The A5's coefficient of drag is down to a slippery 0.25, while Audi's engineers lipo'd 132 pounds of fat.

Recharge Wrap-up: Chevy Volt named KBB "Best Buy," slow BMW i3 sales in Germany

The Chevrolet Volt has been awarded Kelley Blue Book's Electric/Hybrid Car Best Buy for 2015. KBB cited the car's electric commuter capabilities, extended range, acceleration, design and overall value as reasons to place it above the Nissan Leaf, BMW i3 and Toyota Prius. It works well in the real world, and doesn't leave drivers with range anxiety. Plus, it's comfortable, and a fun car to drive, according to KBB. Read more at Kelley Blue Book. The BMW i3 is seeing slow sales in Germany. BMW has sold about half the number of i3s it expected in its home country, with about 1,900 sold in the first nine months. BMW projected sales of 5,000 to 6,000 in the first year. BMW partly blames long shipping times for the slow sales, and the company is offering incentives in hopes of getting more people to adopt the electric car. In the US, BMW sold more than 1,000 units each month between August and October. Read more at Green Car Reports. Audi is pursuing new carbon-neutral synthetic fuels - or e-fuels - such as Audi e-diesel. Audi's newest project uses electrolysis of water to create hydrogen, which it then reacts with CO2 extracted from the air. The result is a liquid - called Blue Crude - full of energy from hydrocarbon compounds. The Blue Crude can then be converted into a sulfur-free synthetic diesel called e-diesel. This e-diesel can be used as a drop-in fuel, blended into fossil diesel for a more renewable fuel. Read more at Hybrid Cars. Uber is partnering with Spotify to allow passengers to choose what music they listen to during their ride. Users will be able to choose their own playlist that will be ready and playing for them when they are picked up. It offers a more personalized experience from the ride-hailing service, which, according to Uber CEO Travis Kalanick, is "nirvana" for music lovers. Paying Spotify users will be able to use the feature initially in London, Los Angeles, Mexico City, Nashville, New York, San Francisco, Singapore, Stockholm, Sydney and Toronto.
