New car market raining on convertibles' parade

Whether fitted with soft or hard folding lids, today's droptops are better than ever for year-round motoring. Advancements in power top mechanisms, sealing, aerodynamics, structural rigidity, rollover safety and creature comforts like heated and cooled seats mean that modern convertibles are more versatile and better to drive than ever before. Yet the segment's sales took a dive during the recession and haven't come back, Automotive News reports.
Part of that is because automakers are looking at today's more sensible buyers and simply not developing as many new models, and that lack of fresh iron is curbing sales. AN cites R.L. Polk data which notes that only about one percent of new vehicles registered in the US last year had tops that folded. Back in 2009, it was 1.4 percent, and it was 2 percent in 2006. All-in, some 151,636 convertibles were registered in 2012. That's more units more than were registered in each of the past three years, but the market has also grown as the economy has picked up speed, and as a percentage of new vehicles purchased, convertible sales are lagging.
Thus far in 2013, the Ford Mustang is America's top-selling convertible, with 6,421 units registered through the end of April, followed by its rival, the Chevrolet Camaro, at 4,751 units. The Volkswagen Beetle isn't far behind, with 4,305, but from that point, it's a steep drop off to the fourth-place Mercedes-Benz SL-Class and its 2,380 sales.

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 Mustang to get four-cylinder in Europe, but not US

Fans of the Ford Mustang SVO, which was produced from 1884 through 1986 with a turbocharged 2.3-liter four-cylinder engine and a manual transmission, may be interested to know that Ford is reportedly going to introduce something similar for 2015. But don't get too excited if you live in the US, as Edmunds reports that the vehicle will be offered in Europe only. Boo!
According to the report, Ford will put a version of its EcoBoost turbocharged four-cylinder into the engine bay of the Mustang. The engine would be enlarged from its current 2.0 liters to 2.3 liters, taking horsepower from 252 to around 300. The well-known 5.0 V8 engine will also be available in Europe.
"The Mustang is uniquely Ford and has a huge fan base here in Europe. Now those fans have something to look forward to and we look forward to providing more details in the near future," says Ford of Europe CEO Stephen Odell. That's great... but why not offer buyers in the States the (likely) fuel-efficient turbo option, too?
