And the Top Gear UK Cars of the Year for 2013 are...

Those loony Brits at Top Gear have named their Car of the Year, and if you're thinking it's the McLaren P1, Jaguar F-Type, Land Rover Range Rover Sport or Rolls-Royce Wraith, we're sorry to inform you that none of those Anglo automobiles earned the crown. In fact, the winner of Top Gear's most prestigious award is quite the surprise.
Of course, those cars weren't without their own awards. The P1 was the top hypercar (sorry, Porsche 918 and Ferrari LaFerrari), while the F-Type netted best convertible and the Range Rover Sport was voted SUV of the Year. Other honorable mentions included the Mercedes-Benz SLS AMG Black and S-Class, the Porsche 911 GT3, the BMW i3 and the Ferrari 458 Speciale. The winner, though, wasn't even a high-dollar supercar. It was the Ford Fiesta ST.
Yes, the Fiesta ST beat out some off-the-wall cars like the revolutionary Volkswagen XL1 and the bonkers Peugeot 208 T16 Pikes Peak, not to mention all the cars we listed above, to take the title of Top Gear Car of the Year. And if you've driven one, you'll completely understand why.

Shelby American cleans house of 14 concept cars

Typically when an automaker rolls out a concept car or pre-production prototype, it does its tour and then disappears into the company's archives. Maybe it will be displayed for the public to see in the company's own museum or maybe it will spend most of its time under covers in a warehouse somewhere, but every once in a while, an automaker will open up its history and start selling off its concept cars. For Shelby American, "once in a while" has just rolled around.
The House that Carroll Built is moving from its previous headquarters at Las Vegas Motor Speedway to a new facility off of the Las Vegas strip, and in the process is liquidating fourteen of the rarest cars in its collection. That presents a tremendous opportunity for muscle car collectors to bring one or more of these snakes home.
As you might expect, the catalog is composed mostly of Mustangs, but not exclusively. There's a pair of 289 Cobras: the last of the 50th anniversary slab-sided continuation cars and an original development vehicle, offered at $200,000 apiece. At the other end of the spectrum you'll find the 2013 Shelby Raptor concept for $125k and Focus concept for $50k. And of course there are the Mustangs.

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.
