November U.S. new car sales mixed as automakers deepen discounts

DETROIT — Major automakers posted mixed U.S. November new vehicle sales on Friday and predicted a competitive December as they rushed to sell vehicles and boost their numbers before 2017 ends. Automakers are trying to sell down 2017 model-year vehicles, offering high discounts to consumers as the year-end nears. In 2016, the industry reported record annual sales of 17.55 million units. According to consultancies J.D. Power and LMC, discounts have been above 10 percent of the average transaction price for 16 of the past 17 months, a level experts say is unhealthy and unsustainable. The November sales results come as the National Automobile Dealers Association said on Friday it expects new vehicle sales to decline to 16.7 million units in 2018, after dropping to 17.1 million for the full year in 2017. If that forecast comes true, the race to move new vehicles off dealers' lots will only intensify next year. Brandon Mason, a director at PwC's automotive practice, said a worrying trend for the industry was a rising number of subprime loans. He said subprime levels are at just over 20 percent of originations, against more than 30 percent prior to the Great Recession, but recent increases remain a concern. "That's a bit of a red flag," Mason said. "It's something to keep an eye on as we move into 2018." November results by automaker: General Motors: Sales fell 2.9 percent, with sales to consumers flat against the same month in 2016. Much of the decrease was driven by lower fleet sales. GM said strong SUV and crossover sales pushed its average transaction price for the month above $37,000 for the first time. The level of unsold cars, which has been a concern for analysts and the industry, rose slightly to 83 days' supply, from 80 days at the end of October. "More vehicles are sold in December than any other month, and we are very well positioned because we have momentum in so many segments, but especially in crossovers," said Kurt McNeil, U.S. vice president of sales operations. Fiat Chrysler Automobiles: Fleet sales are low-margin, and FCA in particular has targeted a significant reduction in this type of sale in 2017. It posted a 4 percent overall decrease in sales for November, but fleet sales were down 25 percent while sales to consumers were up 2 percent on the year. Ford: The No. 2 U.S. automaker reported a 6.7 percent increase for the month, with fleet sales up nearly 26 percent and retail sales 1.3 percent higher than in November 2016.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.

Honda, Nissan, and Toyota expand Takata recall by millions worldwide

Honda, Nissan, and Toyota are expanding their global Takata airbag inflator recalls to cover millions of additional vehicles. Toyota alone is adding about 5 million vehicles to its campaign globally, and over 600,000 of those are in the US, according to Automotive News. Nissan's expansion includes an estimated 1.56 million cars worldwide, including about 326,000 in North America, but the exact models from the company are not yet known. According to Automotive News, Honda has also announced plans to increase the scope of its campaign but hasn't yet disclosed specific models, total numbers, or their location. Company spokesperson Chris Martin tells Autoblog that none of these vehicles are in the US, though. In the US, Toyota is replacing the driver's side front inflators on 160,000 examples of the 2004 and 2005 RAV4 nationwide. It's also swapping out the front passenger side parts for 177,000 units of the 2003 and 2004 Tundra (pictured above) and 2004 Sequoia. The automaker is also expanding its regional recalls in high-humidity areas to include the passenger-side inflators of 300,000 more vehicles. In total, the affected models are 2005-2007 model-year Corolla, Matrix, Sequoia, and Lexus SC; plus the 2005-2006 Tundra is included, as well. All of the states that are covered by this campaign are listed in Toyota's announcement, below. In a statement to Autoblog, Nissan said that it's currently working with the National Highway Traffic Safety Administration on this campaign. "We expect to have a more formal statement and additional information by Friday, May 15," the company said. TOYOTA EXPANDS TAKATA AIRBAG SAFETY RECALLS TORRANCE, Calif., May 12, 2015 – Toyota Motor Sales, U.S.A., Inc. today announced that it is expanding its recalls involving Takata air bag inflators. First, Toyota will conduct a recall to replace Takata-supplied driver front airbag inflators on approximately 160,000 model year 2004 and 2005 RAV4 sport utility vehicles. The inflators could potentially be susceptible to rupture when deployed in a crash, increasing the risk of injury to vehicle occupants. For similar reasons, Toyota will expand two existing recalls for Takata-supplied front passenger airbag inflators, namely: Toyota's nationwide recall launched in April 2013 will expand to include approximately an additional 177,000 model year 2003-2004 Tundra and model year 2004 Sequoia vehicles.
