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.

From Expedition to Navigator: our predictions for Lincoln's SUV

In the midst of all the buzz surrounding the new aluminum Ford Expedition and Expedition Max, we remembered the other large SUV the Ford Motor Company showed last year, the Lincoln Navigator concept. And since the Navigator has historically been built on the Expedition platform, we figured there's no better time to focus some of our predictions for the big Lincoln. First off, let's take a look at design. Having seen the new Expedition, we're fairly confident that the Navigator will look almost exactly like its concept. The strong similarities between two mean the Expedition serves as a preview of what a production Navigator will look like. For example, both vehicles' greenhouses we can see that the shape of the C-pillars are nearly identical. The only difference is that the Expedition's are painted body color, while the Navigator's are painted black. Additionally, the character line running along the top of the doors on both vehicles is roughly the same height. The same goes for the more subtle crease near the bottom of the doors. We also see no reason why Lincoln wouldn't use the full width taillights, fender vent, and grille treatment it used on the concept. Those are all easy design changes to create differentiation, and they're all right inline with the cues set by the Continental.

The Expedition and Expedition Max will be offered with a 3.5-liter EcoBoost as well, so we know it will fit. We expect the Expedition's engine will produce 375 horsepower and 470 lb-ft of torque as it does in the F-150. That's less power than the Navigator concept, but it would be reasonable to make the production Navigator a bit more powerful than its lowly Ford brethren to help justify the increased price tag. Towing capacity will probably be about the same between the Ford and Lincoln, which should be something over 9,000 pounds. The Navigator will probably use the same two-wheel-drive and all-wheel-drive drivetrains, too. Inside is where the Expedition and Navigator will likely differ the most, particularly in seating. The Expedition offers seating for up to eight with an available second-row bench seat, and the Navigator concept had captain's chairs for every row. We're expecting the Navigator will only offer second-row captain's chairs since the cramped third row would be a waste of nice buckets.

Exceptionally rare '65 Ford GT40 Roadster prototype up for auction

Think of mid-engined supercars and your mind is bound to gravitate towards Europe, but the United States has been known to make a handful from time to time - exceptional vehicles from the likes of Vector, SSC, Mosler, Hennessey, and Saleen. But long before any of those came around, Ford famously became obsessed with beating Ferrari at its own game, leading to the development of the iconic GT40.
The story is well known, sending Ford to the checkered flag at Le Mans four times in a row in the late 1960s. Ford and Shelby also built over 100 for public consumption, but just four of them were roadsters. Of those only one remains in original condition, and now that exceedingly rare example going up for auction.
Consigned to RM Auctions for its mid-August sale during Pebble Beach weekend in Monterey, California, this 1965 model is the first GT40 Roadster built. It was used as a development and demonstration vehicle for Ford and Shelby. Carroll Shelby himself drove Henry Ford II in this very car during one of many test and demo events, this time held for Ford's board of directors in Los Angeles.
