Watch how Ken Block spent his weekend in Barbados

Regardless of what you think of his skill as a racer, Ken Block is an expert showman. At this point, he has a career of showing up around the world to do vehicular stunts, and he's still able to go racing as well. It's a pretty sweet niche to carve out. Recently, Block was in Barbados to participate in Top Gear Live and the first event of the Global Rallycross Championship season, and Ford Racing produced a short video to show off his exploits.
It looked like a great show. Block got to race Lewis Hamilton in a Mercedes-Benz Formula One car and had a very weird crash during a Rallycross race that put his Ford Fiesta on its roof. Top Gear also released an extended look at Block and Hamilton's spectacle with the two of them expertly sliding around. Scroll down to watch the videos and get a taste of Block's tropical racing adventure.

Ford Fusion and Fusion Hybrid nab five-star ratings from NHTSA

Ford's Fusion and Fusion Hybrid have both received the highest five-star overall safety rating from the National Highway Traffic Safety Administration. The rating is a big upgrade for the Fusion, which was completely redesigned for 2013. The previous model fell one star short of the top rating, after scoring only three stars in the frontal crash test and four stars in the side crash test and rollover evaluations. The 2013 Fusion received four stars in side crash and rollover testing and a full five stars in the front crash test.
Test results for the 2013 Fusion and Fusion Hybrid were greatly improved at least in part due to Ford's Personal Safety System. The system utilizes smarter sensors to gather crash data and tailor the car's restraint systems to the occupants. Seatbelt usage and seat position are taken into account to ensure airbags deploy with less pressure for smaller drivers, more for larger drivers.
The 2013 Fusion twins also received the Insurance Institute for Highway Safety Top Safety Pick+ designation. Read the official press release 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.
