Buick tops in Consumer Reports' annual brand rankings

Buick is the first US-based automotive brand to crack the top 10 in Consumer Reports magazine's annual brand report cards. US automakers also placed three vehicles on the magazine's list of "top picks" for vehicles, the first time that's happened in 17 years. The rankings were unveiled Tuesday in the magazine's annual auto issue. Buick placed seventh in the brand rankings. But the brand rankings and top picks still were dominated by Japanese and German manufacturers, with Lexus, Mazda, Toyota, Audi and Subaru taking the top five brand spots. The magazine calculates each brand's overall score with a composite of its vehicles' road-test scores and reliability scores for each model in its annual survey of subscribers. It's the third year for the brand rankings. Porsche placed just ahead of Buick at number six, while Honda, Kia and BMW rounded out the top 10 brands. Mercedes-Benz, Acura and Infiniti all suffered precipitous declines in their rankings due to unreliable new models or poor road test scores. Mercedes fell out of the top 10 to 21st, while Acura dropped from number two to 11 with an unimpressive test of the new RLX sedan, the magazine said. In the model rankings, the top overall finisher was California-based Tesla's Model S electric car, for the second year in a row. The Model S, which cost the magazine $89,650, finished first due to its performance and technical innovations, the magazine said. Buick's Regal midsize car beat the BMW 328i as the top sports sedan, and the Chevrolet Impala was named the top large car. The model rankings show Consumer Reports' favorite among the 270 vehicles its team has recently tested. The rankings are closely watched in the auto industry, since shoppers consistently cite Consumer Reports as a main source of car-buying advice. Other top picks included the Subaru Impreza in the compact car category, Subaru Legacy in midsize cars, Toyota Prius as the best green car, Audi A6 luxury car, Subaru Forester small SUV, Toyota Highlander midsize SUV and the Honda Odyssey minivan. Japanese vehicles won six of 10 top pick categories, but that was the smallest number in the 19-year history of Consumer Reports top picks. "For years domestic automakers built lower-priced and lower-quality alternatives to imports, but those days are behind us," said Jake Fisher, the magazine's director of automotive testing. But other U.S.-based automakers still had problems.

Tesla adds free titanium underbody shields to Model S to prevent fires

Following a garage fire incident with a Model S EV last year, Tesla Motors quickly sent out an over-the-air software update to adjust how the car charges. Following two on-road fires caused by road debris that struck the underside of different Model S EVs (one in Washington State and the other in Tennessee), Tesla basically said, that it was a random thing, and the car is perfectly safe. The company later sent out a software update to have the car ride a bit higher at highway speeds. Today, Tesla is offering a more substantial solution. Tesla CEO Elon Musk has announced that all Model S EVs built since March 6 have a stronger triple underbody shield that should "bring this [fire] risk down to virtually zero." The company conducted 152 tests using, "every worst case debris impact we can think of, including hardened steel structures set in the ideal position for a piking event, essentially equivalent to driving a car at highway speed into a steel spear braced on the tarmac" and is now confident that there's basically nothing that can break through the new barriers. As you can see here, the shields prevent a concrete block, a three ball tow hitch and a steel alternator from puncturing the car's underside. The new shields should "bring this [fire] risk down to virtually zero." Any Model S owner who wants the new triple shield can ask for it, and even if they don't ask, the structure will be installed whenever the car is next in for service. The three layers of the shield include a rounded, hollow aluminum bar, a titanium plate and "a shallow angle, solid aluminum extrusion." The new shields, "only have a 0.1 percent impact on range and don't affect ride or handling," Musk writes, which means there's no reason for Model S owners not to get the upgrade. You can read all of Musk's explanation below. Tesla Adds Titanium Underbody Shield and Aluminum Deflector Plates to Model S By Elon Musk, Chairman, Product Architect & CEO In 2013, two extremely unusual Model S collisions resulted in underbody damage that led to car fires. These incidents, unfortunately, received more national headlines than the other 200,000 gasoline car fires that happened last year in North America alone. In both cases, the occupants walked away unharmed, thanks to the car's safety features. The onboard computer warned the occupants to exit the vehicles, which they did well before any fire was noticeable.

Tesla gigafactory will source materials from North America to keep things green

It's one thing for the Big 3 to get tires and engine parts from cities along the US Rust Belt. It's another thing altogether, though, for Tesla Motors to source far more esoteric materials like graphite, cobalt and lithium from Canada and the northern US. But that's what the California-based company has in mind, and it's all in the name of environmental friendliness and cost, Bloomberg News says. Tesla is looking to bring its raw-material sourcing to this side of the Pond by the time it opens its massive gigafactory that may produce as many as 500,000 vehicles annually, Bloomberg says, citing Tesla spokeswoman Liz Jarvis-Shean. And while the raw-material price may be higher (and driven up further with the additional demand from Tesla), those costs may be offset by the fact that there will be far less transportation and logistics involved. "When all costs are considered, it should be cheaper to source most materials from as nearby as possible" - Tesla's Liz Jarvis-Shean "Transportation impacts are very significant on the heaviest raw materials if they need to be moved from halfway around the world," Jarvis-Shean wrote in an e-mail to AutoblogGreen, adding that there will be additional cost savings from reduced shipping time and less transit-related working capital requirements. "In the long term, when all costs are considered, it should be cheaper to source most materials from as nearby as possible." There are geopolitical issues as well. For instance, China is shutting down some of its graphite mines because of pollution issues, while much of the world's cobalt comes from war-torn Congo, though Tesla says it gets its cobalt from the Philippines. Most of the graphite in Tesla's Model S is of the synthetic variety from Japan and Europe. Of course, Tesla's still trying to figure out where to put its gigafactory, and has said it will be in one of four states: Arizona, Nevada, New Mexico or Texas. The factory will cost an estimated $5 billion and may support 6,500 jobs, so state governments are already starting to campaign to be the automaker's future production home. Regardless, Jarvis-Shean estimated that the sheer economies of scale from the gigafactory will reduce battery-pack costs per kilowatt hour for the company's "mass market" model (sometimes referred to as the Model E) by 30 percent after a full year of production.
