Ford finds flex-fuel engine design plays big role in emissions output

How bad is ethanol for your engine? There's been a lot of debate on this issue as the US considers upping the biofuel content in the national gasoline supply from 10 percent (E10) to 15 percent (E15). The ethanol industry and some scientists say higher ethanol blends show no "meaningful differences" in new engines while the oil industry says ethanol creates health risks. Researchers working at the Ford Research and Innovation Center decided to take a closer look at how a wide range of gas-ethanol blends - E0, E10, E20, E30, E40, E55 and E80 - affected the emissions coming out of a flex-fuel 2006 Mercury Grand Marquis. To see the full report, printed in the journal Environmental Science & Technology, requires payment, but there is an abstract and Green Car Congress has some more details. The gist is that, "with increasing ethanol content in the fuel, the tailpipe emissions of ethanol, acetaldehyde, formaldehyde, methane, and ammonia increased." At least NOx and NMHC emissions decreased. The researchers say that the effects are due to the fuel and "are expected for all FFVs," but that the way that a manufacturer calibrates the engine will affect NOx, THC, and NMOG emissions. It's this last bit that's important, since the researchers found, "Higher ethanol content in gasoline affects several fundamental fuel properties that can impact emissions. ... These changes can have positive or negative effects that can depend on engine design, hardware, and control strategy. In addition to direct emissions impacts, higher ethanol content fuel can also provide more efficient combustion and overall engine operation under part-load conditions and under knock-limited higher-load conditions." So, as we head towards more ethanol in our fuel supply (maybe), manufacturers are going to need to learn how to burn it most efficiently.

Weekly Recap: Volvo buys Polestar, makes performance a priority

Volvo is taking its performance business in-house, and the Swedish carmaker announced Tuesday that it bought tuning company Polestar, which has long been known for producing sporty Volvos. The move allows Volvo to ramp up its performance business, and it plans to increase Polestar-branded vehicle sales to 1,000 to 1,500 annually, up from the 750 total projected for this year. The companies have been working together on motorsports projects since 1996. Financial terms of the sale were not released, and Polestar workers will move over to Volvo. Former Polestar owner Christian Dahl will keep control of the Polestar racing team and operate it under a new name. In addition to sales volume, Volvo has ambitious plans for other parts of Polestar, including its aftermarket business. Volvo also said it will use its twin-engine hybrid technology for Polestar models in the future, though specifics and timing were not revealed. Meanwhile, Volvo announced it will offer a run of 265 total Polestars in the United States for the 2016 model year, with S60 and V60s available. "Driving a Volvo Polestar is a special experience. We have decided to bring this experience to more Volvo drivers, placing the full resources of Volvo behind the development of Polestar as the model name for our high performance cars," Volvo CEO Hakan Samuelsson said in a statement. OTHER NEWS & NOTES 2016 Chevy Silverado, GMC Sierra, get nose jobs Automakers tend to refer to light updates as 'facelifts,' and that's exactly what Chevy gave the 2016 Silverado and GMC Sierra. Chevy slightly changed the front end of the truck. Using the one photo released of the new Z71 model as a guide, we can see that the headlights went from a stacked vertical design to single bulbs, and they are set on top of LED running lights. The grille has more body-colored elements instead of shiny metal, and the hood has a new line running down the middle (look really closely). The design theme will be similar across the portfolio, though materials and details will vary, a spokesman said. Some models, like the High Country and LTZ will have more chrome, and the LEDs are only for the upper trims. Chevy also said it will use the eight-speed automatic transmission on more versions of the Silverado, and it updated the MyLink feature to support Android Auto and Apple CarPlay.

Gary Cooper's 1935 Duesenberg SSJ fetches record price at Pebble Beach

The 1935 Duesenberg SSJ formerly owned by Gary Cooper sold for a jaw-dropping $22 million over the weekend at the Gooding & Co. Pebble Beach auction, setting a record for the most valuable pre-war car ever sold at auction. It also appears to have become the most expensive American collector car ever sold at auction, eclipsing the very first Shelby Cobra ever made, which sold for $13.75 million in 2016. The Duesenberg was also the lone American-made entrant in the list of top 10 sellers, which was crowded with the names Ferrari and Porsche. You have to go all the way down the list to No. 21 to find the next American car: a 1930 Packard 734 Speedster Phaeton, which sold for a mere $1.127 million. All told, Gooding & Co. said it realized more than $116.5 million in auction sales over the weekend, with a whopping 25 cars sold for north of $1 million, an 84 percent sales rate and an average transaction price of $947,174. Clearly this is how the other half 1 percent lives. Gooding & Co. said there were five world-record sales at the auction. Joining the Duesenberg were a 1955 Ferrari 500 Mondial Series II, which sold for $5.005 million; a 1958 Ferrari 250 GT Tour de France Berlinetta, $6.6 million; a 1967 Ferrari 330 GTC Speciale, $3.41 million; and a one-of-two 1966 Ferrari Dino Berlinetta GT, $3.08 million. Oh, and that 1969 Ford Bronco test vehicle we told you about? The one that was rebadged by Holman & Moody as a Bronco Hunter? It sold for $121,000, which was well below the expected range of $180,000 to $220,000. Perhaps it was the presence of all those gorgeous Porsche Spyders and Ferraris that meant collectors weren't interested in boxy, utilitarian off-roaders. View 24 Photos Gooding and Co. had expected the convertible Duesenberg coupe to go for more than $10 million. It was one of only two of its kind built by Duesenberg — the other having gone to Clark Gable — with a specially shortened, 125-inch wheelbase and a supercharged straight-eight with double overhead cams, able to produce around 400 horsepower and a top speed of 140 miles per hour. It features a lightweight open-roadster bobtail body produced by LaGrande out of Connersville, Ind. The car was also owned at one point by race driver Briggs Cunningham.
