Top Gear pits Hennessey VelociRaptor vs. Range Rover Sport SVR

As a television series, Top Gear is in limbo with an intent to return, but no hosts yet. However, it's magazine and website continue to bring us clips like this one. While the video might lack the show's charismatic hosts, this is an opportunity to see a drag race between a Land Rover Range Rover Sport SVR with 550 horsepower and a Hennessey VelociRaptor with 623 hp. The duel between these two supercharged V8s definitely sounds great. Both rugged models start at the line growling angrily at each other like dogs ready for a fight. You have to watch the clip to see whether the more powerful VelociRaptor feeds on the SVR, though.

2015 Ford F-150 to get 2.7-liter EcoBoost?

As we prepare for the arrival of the all-new, next-generation Ford F-150, rumors about the new truck are picking up steam. Naturally, many of said rumors aren't just related to the way the truck will look (it's expected to take design cues from the Atlas concept shown above), they're tied to what's going to motivate the Blue Oval mainstay, with Ford's EcoBoost range likely to play an increasingly key role. While we're still expecting the current 3.5-liter, twin-turbocharged V6 to retain its position as a premium alternative to Ford's naturally aspirated V6 and V8, a Canadian automotive news site is proposing that the Dearborn automaker is also preparing a new, more fuel-efficient downsized EcoBoost option.
Autos.ca is reporting that a new, 2.7-liter, twin-turbocharged V6 could find its way into the lighter, aluminum-intensive truck. The new engine supposedly makes use of asymmetrical turbos to generate 320 horsepower and 370 pound-feet of torque - substantially more impressive numbers than the current 3.7-liter base engine's 302 ponies and 278 lb-ft - while offering improved fuel economy and emissions. The new 2.7 EcoBoost (internally dubbed "Nano") isn't expected to supplant the naturally aspirated V6 as the F-150's base engine, it's expected to slot in above directly it.
Naturally, we're prescribing more than a few grains of salt to go with these rumors, at least until Ford debuts the next F-150 at the 2014 Detroit Auto Show, a reveal we'll be covering in a mere two weeks.

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.
