TX officer allegedly lets 140-mph street racer go with a warning [w/poll]

Being pulled over by the police is one of the most nerve-racking situations that a driver can go through, and it's even worse when you know that the officer has you dead to rights for speeding well over the posted limit. In this video, the driver of a heavily modified Ford Mustang with a claimed 966 horsepower at the rear wheels could have easily lost his ride for doing triple-digit speeds and street racing, but a friendly Texas police officer appears to send him on his way with a simple warning.
What's more, the driver in question wasn't just speeding - his Mustang was the camera car for a bunch of rolling street races in the wee hours of the morning on a Texas highway. The driver was more than willing to mix it up in the action, too. Eventually the cops catch on and pick the 'Stang to pull over, but not before the Ford owner runs a claimed 140 mph. With only audio to go on after the car is pulled over, the police officer seems incredibly nonchalant about catching someone who was so brazenly breaking the law. Incredibly, the patrolman actually tells the driver that he's seen everyone racing tonight but ignored them. With traffic picking up, the cop says that it's time to "cut it out" and go home for the night. As far as this video shows, that was the end of it.
Warning: There is explicit, not-safe-for-work language in the video below.

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.

Ford lowers MPG ratings on six vehicles

Ford has announced that it will be lowering the fuel economy ratings on a number of its 2013 and 2014 model year vehicles after an error was discovered in the company's internal testing data. The EPA has been notified.
Worryingly for Ford, the vast majority of the vehicles affected are hybrids, including the C-Max, Fusion and MKZ in both hybrid and plug-in varieties (where applicable). Also covered as part of the rerating is the entire lineup of 2014 Fiesta engines, with the exception of the ST, including the turbocharged, three-cylinder EcoBoost.
The C-Max was originally rated at 47/47/47 mpg, but dropped to 43/45/40 last year and now to 40/42/37.
