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.

Ford GT successor to debut in Detroit and go racing

Anticipation for all of the exciting reveals at the 2015 Detroit Auto Show just a few weeks away is building to a fever pitch, and rumors are mounting that Ford has a big surprise in store in the shape of a future performance halo model. Insider sources speaking to Autoweek claim the next Ford supercar is definitely going to be revealed at the Detroit show in early January. However, the model is not necessarily the next-generation Ford GT in terms of its name or design aesthetic. Instead, one of these people indicates that the new halo model might drop retro styling altogether. If the latest reports are to be believed, Ford's high-performance project goes beyond something to just grab headlines and rocket down the street. According to Autoweek, the automaker is also reportedly employing Chip Ganassi Racing to run a two-car racing effort in the Tudor United SportsCar Championship in 2016. That would allegedly include a trip to the 24 Hours of Le Mans to race on the 50th anniversary of the Ford GT40's win in 1966. The speculation goes that at least the racing version might use a twin-turbo EcoBoost V6 for power. However, the motorsports part of the program may not be announced during the auto show reveal. Rumors about the new halo car from the Blue Oval and its racing intentions have been percolating for months. The company might have considered an LMP2 entry, but speculation popped up later about the production supercar. A more recent report suggested that Ford might show a new Shelby GT350R Mustang, a successor to the F-150 Raptor and next Ford GT in Detroit.

Lego provides one of the cheapest ways to own a Bugatti Chiron

Just over a month ago, we got a look at one of the latest Lego Speed Champions sets when Ford revealed the GT and GT40 kit. Now we get to see the rest of the lineup, and it's chock full of F1 and supercar goodness. The official Lego images show that the Bugatti Chiron, Mercedes-AMG GT3, Ferrari FXX K, and F1 cars from Ferrari and Mercedes all made the cut. Each set gets some unique features and most include interchangeable wheel covers. The Chiron comes with some tiny cones suitable for desk slaloms and the Mercedes-AMG GT3 gets an alternate nose. The FXX K comes has the most impressive selection of accessories, though, as it includes a dyno and engine run stand. The F1 sets are divided similarly, but with Mercedes getting more extras. The Brick Fan also reports that the Mercedes kit may be exclusive to select stores. The Ferrari kit only comes with a starting light, but the Mercedes set includes a garage, starting lights, and winner's circle. It'll be up to you whether you put Hamilton or Rosberg in that winner's circle. According to The Brick Fan, these kits are set for release in winter 2017. Since the Ford GT set has a release of March 1, we expect the rest will hit stores in the next couple of months. They're sure to be great additions to anyone's existing Lego garage.
