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.

2018 Ford Expedition spied looking stylish

The Ford Expedition and Lincoln Navigator got a cool reception for their 2015 warmed-over redesign. But with big, high-riding vehicles once again in vogue, Ford is pushing ahead with a ground-up redesign of its biggest SUVs. Based on these spy shots, the Expedition will continue to serve as the Navigator's more affordable twin. Yes, that's a bold prediction, considering we still haven't spotted Lincoln testing the new Navigator, but study the greenhouses on this Expedition prototype and the Navigator Concept from New York – from the arrow-straight belt line to the extra-long rear window to the aggressively raked windshield, this Expedition's overall profile is broadly similar to what Lincoln previewed earlier this year. While our spies claim the new Expedition will look to the F-150 for design inspiration, we see a departure from past Expedition tradition. Unlike the supposed Expedition spy shots we showed you nearly a year ago – which was nothing more than an SUV with an F-150's nose grafted on, this prototype's front-end styling looks softer and more aerodynamic, with a smaller grille and headlights, almost like an Escape or Edge. This kind of change would explain the additional front-end camouflage. In back, our spies rightly point out that Ford fitted a faux rear end to disguise the rear window's rake – expect the real thing to feature the angled rear window previewed on the Navigator Concept. Look at the last image in the gallery for a better idea of how the Expedition's rear window will actually look. We can't say a lot about the taillights, because of the camo, but non-LED taillights are present. We'd expect Ford to offer LEDs on higher trim levels. While the F-150's styling might not make the transition to the Expedition, its powertrains and emphasis on lightweight aluminum will. Our spies report the biggest SUV will ride on a new T3 platform and feature an aluminum body, with the F-150's 3.5-liter EcoBoost V6. Expect a ten-speed automatic transmission and start/stop tech for sure, while the smaller 2.7-liter, twin-turbo V6 could slot in as the Expedition's base engine – we're less sure on that one. And we're even more uncertain of the rumors of an Expedition Hybrid. Our spies report it could mate a 3.5-liter V6 with an electric motor(s) and battery packs for a more economical full-size SUV. Expect to see the 2018 Expedition debut in January, at the 2017 Detroit Auto Show.

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.
