Pebble Beach Concept Car Lawn adds class to the grass

While Pebble Beach is traditionally thought of as the refuge of the pristine and pricey vintage vehicles of the world, there's no shortage of newer vehicles on display. And when we say "new," we mean really new. As in, not even in production new. This is the concept car lawn, and it's home to an eclectic group of vehicles from past and present.
Of course, calling it the "concept car lawn" is a bit of a misnomer this year (as it has been in previous years, too). Production models like the Alfa Romeo 4C were on display, alongside known quantities like the Hennessy Venom GT and modified versions of already-on-sale models, like the Rolls-Royce Phantom Drophead Waterspeed Collection.
There were a few concepts on display, though. Toyota debuted the critically acclaimed FT-1 Concept in a new shade, while BMW's Beijing Motor Show stunner, the Vision Future Luxury, was also parked on the expensive grass. Also appearing were the Nissan GT-R in sheep's clothing, the Infiniti Q50 Eau Rouge, and the recently debuted McLaren P1 GTR.

DC fast charging not as damaging to EV batteries as expected

As convenient as DC fast charging is, there have been lots of warnings that repeated dumping of so many electrons into an electric vehicle's battery pack in such a short time would reduce the battery's life. While everyone agrees that DC fast charging does have some effect on battery life, it may not be as bad as previously expected. Over on SimanaitisSays, Dennis Simanaitis, writes about a recent presentation by Matt Shirk of the Idaho National Laboratory (INL) called DC Fast, Wireless, And Conductive Charging Evaluation Projects (PDF) that describes an ongoing test of four 2012 Nissan Leaf EVs that are being charged in two pairs of two. One pair only recharges from 50-kW DC fast chargers, which the other two sip from 3.3-kW Level 2 chargers exclusively. Otherwise, the cars are operated pretty much the same: climate is automatically set to 72 degrees, are driven on public roads around Phoenix, AZ and have the same set of dedicated drivers is rotated through the four cars. "Degradation depends more on the miles traveled than on the nature of recharging." What's most interesting are the charts on page seven of Shirk's presentation (click the image above to enlarge), which show the energy capacity of each of the four vehicles. When they were new, the four batteries were each tested to measure their energy capacity and given a 0 capacity loss baseline. They were then tested at 10,000, 20,000, 30,000 and 40,000 miles, and at each point, the DC-only EVs had roughly the same amount of battery loss as the Level 2 test subjects. The DC cars did lose a bit more at each test, but only around a 25-percent overall loss after 40k, compared to 23 percent for the Level 2 cars. Simanaitis' takeaway is that, "INL data suggest that the amount of degradation depends more on the miles traveled than on the nature of recharging." The tests are part of the INLs' Advanced Vehicle Testing Activity work and a final report is forthcoming. These initial numbers from IPL do mesh with other research into DC fast charging, though. Mitsubishi said daily fast charging wouldn't really hurt the battery in the i-MiEV and MIT tests of a Fisker Karma battery showed just 10-percent loss over 1,500 rapid charge-discharge cycles.

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.
