Our interview with Jeremy Clarkson and James May, plus SEMA! | Autoblog Podcast #491

This week, David Gluckman and Mike Austin talk SEMA madness, mis-aligned steering wheels, wireless charging, McLarens (they're sports cars!), and decals. We also have an excerpt from a recent interview with James May and Jeremy Clarkson of The Grand Tour and Top Gear fame. As always, we talk about a variety of cars we've been driving and then respond to some questions from listeners. And as a bonus, there's a trivia question mixed in. The rundown is below. Remember, if you have a car-related question you'd like us to answer or you want questionable buying advice of your very own, send a message or a voice memo to podcast at autoblog dot com. Oh, and please send trivia questions! You'll get the honor of stumping your fellow listeners, and we'll thank you too.

Why the Detroit Three should merge their engine operations

GM and FCA should consider a smaller merger that could still save them billions of dollars, and maybe lure Ford into the deal. Fiat-Chrysler CEO Sergio Marchionne would love to see his company merge with General Motors. But GM's board of directors essentially told him to go pound sand. So now what? The boardroom battle started when Mr. Marchionne published a study called Confessions of a Capital Junkie. In it, Sergio detailed the amount of capital the auto industry wastes every year with duplicate investments. And he documented how other industries provide superior returns. He's right, of course. Other industries earn much better returns on their invested capital. And there's a danger that one day the investors will turn their backs on the auto industry and look to other business sectors where they can make more money. But even with powerful arguments Marchionne couldn't convince GM to take over FCA. And while that fight may now be over, GM and FCA should consider a smaller merger that could still save them billions of dollars, and maybe lure Ford into the deal. No doubt this suggestion will send purists into convulsions, but so be it. The Detroit Three should seriously consider merging their powertrain operations, even though that's a sacrilege in an industry that still considers the engine the "heart" of the car. These automakers have built up considerable brand equity in some of their engines. But the vast majority of American car buyers could not tell you what kind of engine they have under the hood. More importantly, most car buyers really don't care what kind of engine or transmission they have as long as it's reliable, durable, and efficient. Combining that production would give the Detroit Three the kind of scale that no one else could match. There are exceptions, of course. Hardcore enthusiasts care deeply about the powertrains in their cars. So do most diesel, plug-in, and hybrid owners. But all of them account for maybe 15 percent of the car-buying public. So that means about 85 percent of car buyers don't care where their engine and transmission came from, just as they don't know or care who supplied the steel, who made the headlamps, or who delivered the seats on a just-in-time basis. It's immaterial to them. And that presents the automakers with an opportunity to achieve a staggering level of manufacturing scale. In the NAFTA market alone, GM, Ford, and FCA will build nearly nine million engines and nine million transmissions this year.

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.
