Mercedes recalls 2,600 S-Class models in two campaigns

If you're the owner of a 2015 S-Class, you may get a notice soon from your local Mercedes dealership to bring in your pride and joy. But only if you own one of the specific models being recalled in two separate campaigns. The larger of the two affects the Mercedes-Benz S550 4Matic, Mercedes-AMG S63 4Matic, and Mercedes-AMG S65 coupes – all from the 2015 model year and manufactured between January 27, 2014, and April 2, 2015. Those models could have had their front seat belts installed on the wrong side, so the driver's side belt may have been fitted to the front passenger seat, and vice versa. Since the seat belt mechanisms are designed for specific sides of the vehicle, they may not lock as required, and the child seat restraint on the passenger side might not work, either. As a result, Mercedes is recalling 2,580 such units in the United States to have those belts inspected and replaced as necessary. In parallel, the Silver Star automaker is also calling in four – that's right, just four – examples of the 2015 S550 Hybrid. In those few units, the fuel pump may not be able to restart the internal combustion engine when needed, and the vehicle could stall. You can read both of the recall notices from the NHTSA below. RECALL Subject : Incorrect Seat Belt Position/FMVSS 208, 209 Report Receipt Date: OCT 14, 2015 NHTSA Campaign Number: 15V657000 Component(s): SEAT BELTS Potential Number of Units Affected: 2,580 Manufacturer: Mercedes-Benz USA, LLC. SUMMARY: Mercedes-Benz USA, LLC. (MBUSA) is recalling certain model year 2015 S550 4Matic Coupe, AMG S63 4Matic Coupe, and AMG S65 vehicles manufactured January 27, 2014, to April 2, 2015. In the affected vehicles, left-side front seat belts may have been installed on the right-side and vice versa. As a result, the installation angle may be incorrect, affecting the seat belt locking behavior. Additionally, the child seat restraint function for the passenger seat would not be available. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection," and FMVSS number 209, "Seat Belt Assemblies." CONSEQUENCE: If the seat belt is installed improperly, it may not properly restrain the seat occupant in the event of a crash, increasing the risk of injury. REMEDY: MBUSA will notify owners, and dealers will inspect the installation of the seat belts, correcting them as necessary, free of charge.

Here’s how 20 popular EVs fared in cold-weather testing in Norway

Electric vehicles are known to suffer diminished performance in cold weather, but some do a better job than others hanging onto their range capacity while cabin heaters and frigid outdoor temperatures sap power from their batteries. Recently, the Norwegian Automobile Federation put the 20 of the best-selling battery-electric vehicles in the country to the test, to see not only how winter weather affected their range but also their charging times. The major findings: On average, electric vehicles lost 18.5% of their official driving range as determined by the European WLTP cycle. Electric vehicles also charge more slowly in cold temperatures. And interestingly, the researchers learned that EVs don’t simply shut down when they lose power but instead deliver a series of warnings to the driver, with driving comfort and speed levels maintained until the very last few miles. Because itÂ’s Norway, the worldÂ’s top market for electric and plug-in hybrid vehicles by market share, the test included many EVs that arenÂ’t available here in the U.S. But there are many familiar faces, among them the Nissan Leaf, Tesla Models S, 3 and X, Hyundai Kona (known here as the Kona Electric) and Ioniq, and Audi E-Tron. In terms of range, the top-performing EV was the Hyundai Kona, which lost only 9% of its official range, which the WTLP rated at 449 kilometers, or 279 miles, compared to its EPA-rated range of 258 miles on a full charge. It delivered 405 km, just enough to nudge it ahead of the Tesla Model 3, which returned 404 km. Other top performers included the Audi E-Tron, in both its 50 Quattro (13% lower range) and higher-powered 55 Quattro (14% lower) guises; the Hyundai Ioniq (10% lower); and Volkswagen e-Golf (11% lower). At 610 km (379 miles) the Tesla Model S has the longest WLTP range of all models tested and went the furthest, but still lost 23% of its range, though it also encountered energy-sapping heavy snow at the end of its test, when many cars had dropped out. The Model 3 lost 28% of its range. The worst performer? That goes to the Opel Ampera-e, better known stateside as the Chevrolet Bolt. It traveled 297 km (about 184 miles) in the test, which was nearly 30% lower than its stated WLTP range. We should also note that Opel, now owned by Groupe PSA, is phasing the car out in Europe and that Chevy recently upgraded the Bolt here in the U.S.

Mercedes-Benz Concept IAA is a modern silver aero

While we English-speaking folk call it the Frankfurt Motor Show, our German friends call this week's bi-annual confab the Internationale Automobil-Ausstellung, or IAA. At first glance, then, you might think Mercedes-Benz named its Frankfurt concept, the Concept IAA, after the show it'd debut at. But, the Concept IAA isn't named for the show. It's actually an abbreviation for Intelligent Aerodynamic Automobile, and it's very aerodynamic indeed. This four-door coupe can transform, while moving, from its sedan-like design mode to an ultra-sleek, gas-powered fish of a car. This aerodynamic mode has a drag coefficent of just 0.19. That's sleeker than a Tesla Model S, and it ties the rating of the General Motors EV1 electric car. In fact, it's very nearly as aerodynamic as the Volkswagen XL1. The IAA can transform automatically at 80 kilometers per hour (about 50 miles per hour) or via the press of a button. When it enters an aerodynamic mode, eight segments at the back of the car extend out, adding over 15 inches to the overall vehicle length, effectively extending its already tear-dropped-shaped tail. And that's just the most visible aero aid. At the front of the car, flaps in the bumper extend out nearly an inch, while there's a smaller extender in the back bumper. These serve to keep air away from the wheel arches, where turbulence can become an issue. Of course, Mercedes has thought of this, too, fitting "Active Rims" that "alter their cupping from 55 mm to zero," whatever that means. There's even an active aero aid inside the front bumper, where a louver extends backward by 2.3 inches to smooth out the air traveling underneath the car. Outside of its super-slippery mode, the IAA is a relatively handsome four-door coupe, featuring the kind of plunging roofline that wouldn't look out of place on the company's pioneering CLS-Class. The interior is certainly worthy of the CLS, too. It's home to gorgeous white leather and touch-based controls, and in general, looks very luxurious. Mercedes' dogged pursuit of aerodynamics does not mean that the Concept IAA is some gutless ecomobile. Under the skin is a gas-powered, plug-in hybrid system that produces up to 279 horsepower and allows the sleek sedan to hit 155 mph. Its all-electric range is based, of course, on what mode its body is in. It's most impressive in aero mode, where it will cover 41 miles on a single charge. Switch over to design mode, and that figure drops slightly to 38.5 miles.
