These cars are headed to the Great Crusher In The Sky

It happens every year. We bid adieu to some cars and trucks that will be missed, and say good riddance to others wondering how they stayed around so long. Whether they're being killed off for slow sales or due to a new product coming along to replace them, the list of vehicles being discontinued after 2012 is surprisingly long and diverse.
CNN Money has compiled a list of departing vehicles, to which we've added a few more of our own. In the slow sales column, cars like the Lexus HS 250h, Mercedes-Benz R-Class and the full Maybach lineup appear, while the Ford Escape Hybrid, Mazda CX-7 and Hyundai Veracruz are all having their gaps filled with more modern and more fuel-efficient alternatives. Obvious exceptions to the rule include models that still sell in decent numbers like the Jeep Liberty and the Chrysler Town & Country (which will eventually be replaced by a crossover-like vehicle).
Check out our gallery of discontinued cars above, then scroll down for more information.

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.

2015 Ford Focus

Sitting down at the pre-drive briefing with Ford engineers ahead of sampling the refreshed 2015 Focus, water bottles clinked as we wet our whistles before Q&A. While pouring a glass, we noticed something stamped on the bottle label: "1L." One liter. We were palming the exact displacement of the EcoBoost engine our group was about to drive. This was undoubtedly coincidence (such bottles litter every conference and dinner table in Europe) but it served to drive home just how small the total swept volume of Ford's wunderkind powerplant really is. It's tiny.
Of course, this isn't our first run-in with the little triple - we've sampled its turbocharged charms before in Ford's smaller Fiesta. At that time, we found it had plenty of poke for the subcompact, but the larger C-segment Focus carries around another 450 pounds or so and pushes a wider profile through the air. Would the three-cylinder have the stuffing to make the most of the Focus' athletic chassis, or would it be a letdown? Would it be the same as it was when we tested it in a Euro-spec Focus a couple of years ago? There was nothing left for it but to head out on the bucolic roads surrounding Versailles the day after the Paris Motor Show and find out for ourselves.
