More German automakers may be afoul of US emission standards

Volkswagen has plenty of smoke to share, and that may mean fire for other German automakers that make diesel vehicles, says Automotive News. Earlier this month, European Federation for Transport and Environment said that BMW, Daimler's Mercedes-Benz and General Motor's Opel division are among other automakers that may have equipped their vehicles' diesel engines with similar software as VW's. That software was found to reduce emissions while a car is being tested for emissions and shuts down emissions-control systems during normal use. The European environmental group used data from the International Council on Clean Transportation. Automotive News notes that the European environmental group put out its own report earlier this month, before the VW scandal broke loose, but the report was pretty much overlooked. Now, VW is under fire after it was discovered that 2.0-liter diesel engines in the VW Jetta and Golf, and Audi A3, may be programmed to game the emissions system. VW sold almost a half-million diesel vehicles in the US during the past six years. Both BMW and Mercedes-Benz told Automotive News that the issue that befell VW doesn't apply to their diesel vehicles. Earlier this week, Volkswagen admitted its car ran the sneaky software, while the US Environmental Protection Agency (EPA) has started a probe on the company. VW is setting aside more than $7 billion to pay for the alleged violations. Meanwhile, US taxpayers may have spent as much as $51 million a year to pay for subsidies related to VW's diesel vehicle sales in 2009 alone, according to the Los Angeles Times.

2015 Mercedes-Benz SLK250 Quick Spin [w/video]

We car writers tend to have a occupationally limited focus. Autoblog's stock in trade is automotive news and new car reviews, which often steers us towards forgetting existing models about 17 minutes after we've driven it a second time. You guys like reading about the new hotness, too, so it tends to work out. But the wonderful fact is that every car sold today will have a rich/interesting/heroic/tragic life for years to come. And, occasionally, even obsolete makes and models stay interesting. That was my thinking when this 2015 Mercedes-Benz SLK250 came into our fleet. Set to be replaced with the SLK300, with that car's 2.0-liter turbo'd engine, the 250 is already running out the clock in Mercedes dealerships. What's more, my test car came complete with – are you ready for this? – a six-speed manual transmission. I can't tell you the last exact model of Benz that I'd driven with a stick shift, but I can assure you that its engine was carbureted. Considering the odd spec and replacement timeline, my question, as I drove the SLK for a week: was this a unicorn destined to be a driver's dearest find? Driving Notes: Let me not bury the lede any more: the six-speed isn't a game changer for the SLK. Yeah, over the course of a few days I came to be comfortable with the slightly vague clutch and notchy shifter, but I didn't love it. I went blasting on a few back roads, and found the hand-shaker more involving to use than the standard auto, but it was long to throw and not overly precise when I moved up and down between second, third, and fourth. On the other hand, the old 1.8T under the SLK250's bonnet still felt well matched with the base SLK's boulevardier mission. Output of 201 horsepower and 229 pound-feet of torque doesn't give enough gumption to move the hardtop German lump with authority, but it was still enough to be quick off the line and offer easy highway passing. The turbo four didn't sound bad under full throttle, either, but it did rattle like old plumbing when idling in the driveway. Speaking of rattling: the adjustable and Airscarf-equipped seats did a lot of it. (Airscarf, you'll recall, is M-B's brand name for an in-seat fan that blows hot air on your neck; it's nice on a cold day.) Though comfortable and mildly bolstered, the driver's chair made all kinds of funny noises when I got in, got out, or cornered over 20 miles per hour. That's rough for a luxury car with 6,000 (or so) miles on it.

2019 Autoblog Technology of the Year finalists revealed

Every fall, we line up a range of new models with the latest and most compelling automotive technology from the past year. We test everything from semi-autonomous systems like Tesla's Autopilot to trick suspension setups like the Multimatic spool-valve shocks on the Chevy Colorado ZR2. We spend months paring down the list to a small group of contenders. After testing, dinner and healthy debate, we tally up the votes and name our winner. For Autoblog's 2019 Technology of the Year Award, our three finalists are the Cadillac CT6 with Super Cruise, the Infiniti QX50 with Variable Compression Turbo and the Mercedes-AMG E 53 with EQ Boost. Super Cruise is an advanced SAE Level 2 semi-autonomous system, though Cadillac (unlike some of its rivals) is reluctant to push that point. Cadillac would like you to think of this as an advanced driver assistance feature rather than a semi-autonomous system. Super Cruise allows completely hands-free highway driving. Thanks to a driver-facing camera, the system forces the driver to keep his or her eyes on the road even if hands are off the wheel. Although the CT6 is being discontinued, look for Super Cruise to make its way to other Cadillacs soon. VC Turbo is a little more complicated. Basically, Infiniti's 2.0-liter turbocharged inline-four can vary the compression ratio on the fly. In general, turbocharged engines are more efficient than naturally-aspirated engines when on boost, but can perform worse at low revs. VC Turbo allows for a best-of-both-worlds situation, increasing the compression at low revs and backing it off once the turbo spools up. The best part is that it does so seamlessly, with only a dash readout letting you know what's going on under the hood. Our third finalist is the EQ Boost 48-volt system in the Mercedes-AMG E 53. Like VC Turbo, EQ Boost does a lot just beneath the surface. Mercedes has developed a new turbocharged 3.0-liter inline-six and paired it with a small electric motor. While the car can't run on electricity alone, the motor helps improve both efficiency and performance, smoothing shifts and filling in low-end torque before the turbos spool up. Think torque fill, similar to a McLaren P1. Who can complain about better fuel economy and more torque? Look for the 48-volt system to make its way into most of the Mercedes-Benz lineup. The winner will be revealed next week on Autoblog, and we'll present the award Jan. 15 at the Detroit Auto Show. Related Video:
