Xcar gets the scoop on Ford's strategy for the GT at Le Mans in 2016

Ford's plan to return to the 24 Hours of Le Mans in 2016 with the latest GT might have been one of the worst kept secrets in motorsports in recently memory. Even before the road car debuted at the 2015 Detroit Auto Show, rumors were flying about the Blue Oval's strategy. The wait for the official announcement just before this year's race was certainly a long one, but it was probably worthwhile just to see the competition version's spectacular looks. Xcar recently got the chance to interview Ford about the company's objectives for the new racer's development. Both the GT racing and street programs are meant as ways to advance cutting-edge technology and potentially let it trickle down to less-expensive models in the future. This is especially the case when it comes to finding ways to make carbon fiber cheaper and better. Of course, the supercar is also a showcase of what Ford can do competitively, and apparently there are patent-pending suspension parts the company isn't even talking about yet. Ford would love to score a class victory at Le Mans next year, and is pretty clear here and in its earlier promo video that it sees Ferrari as a major rival in the race. While that makes sense historically, the cross-town competitors at Corvette could be an even bigger challenger. That squad has a more recent legacy of success in the 24-hour challenge, including a victory in the GTE-Pro class this year. Related Video:

Ford exec reveals new F-150 Raptor packs 450 horsepower

Between the new GT supercar, Shelby GT350R muscle car and F-150 Raptor off-roader, Ford had quite the array of performance machinery on display at the Detroit Auto Show earlier this month. One thing it didn't reveal about any of the three, however, is how much power they'd pack, but a senior executive at the Blue Oval automaker has reportedly let the cat out of the bag when it comes to the Raptor. During a televised interview during the Rolex 24 at Daytona this past weekend, Ford's product development chief Raj Nair is said to have revealed that the new F-150 Raptor will offer 450 horsepower. That's pretty impressive from a 3.5-liter turbocharged V6, and would put the new Raptor out ahead of the 411 hp produced by the 6.2-liter naturally aspirated V8 in the previous SVT Raptor. That doesn't give us the whole picture, though, because in a vehicle this big especially, torque will play a huge factor. The outgoing Raptor offered 424 pound-feet of twist, and the existing 3.5-liter EcoBoost engine is already producing 420 lb-ft – so it seems fairly safe to assume the new Raptor will eclipse those figures as well, but we'll have to wait for official word to find out for sure.

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.
