Jeep Wrangler EcoDiesel, Porsche Cayenne E-Hybrid and Tesla Cybertruck | Autoblog Podcast #606

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor, Green, John Beltz Snyder and Associate Editor, Joel Stocksdale. With their powers combined, they create a great episode full of driving impressions from the Jeep Wrangler EcoDiesel, Porsche Cayenne E-Hybrid and BMW X6 40i. They return to the topic of the Ford Mustang Mach-E before diving into the Tesla Cybertruck and a future without Buick sedans. Finally, they help a listener choose a new, sporty sedan in the "Spend My Money" segment.

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 C-Max spied with fresh updates

The Ford C-Max hatchback looks to be getting a few cosmetic updates, as evidenced in this latest set of spy photos. Like the smaller Focus, which also received a nip/tuck for the 2015 model year, the C-Max appears to be getting a revised front fascia with slimmer headlamps and a more, shall we say, Aston Martin-like grille. Around back, there looks to be a new bumper with redesigned taillamps, as well.
In other markets, the C-Max people-mover is available with a range of powertrains, but here in the US, it exists either as a traditional gas-electric or plug-in hybrid. The C-Max's fuel economy has been a particular topic of interest lately, with its official fuel economy ratings having been lowered twice since the vehicle's launch. Sales initially suffered a bit following this fiasco, though numbers have since leveled out. It's unclear if Ford is working on any powertrain tweaks for the updated C-Max seen here, however.
Ford has likely spruced up the hatch's interior, as well, though we don't have photos of that at this time. Mum's the word on when we'll see the new C-Max, but our best guess is that it'll arrive sometime in the next year.
