Question Of The Day: Most overlooked heroic engine?

All of us know that the small-block Chevrolet V8 was a masterpiece of engineering that made the high-performance overhead-valve V8 affordable to the masses, and that the Mercedes-Benz OM617 diesel is basically immortal, and that the Toyota R engine defined what it means for a vehicle to be considered Warlord Grade. The AMC straight-six. The Model T engine. The Volvo Redblock. Those engines get the respect they deserve. But what about the engines that we don't think much about, the ones that worked hard in their millions and somehow missed attaining legend status? The list of engines beloved by their aficionados but not thought of often by the rest of us goes on and on: the Renault Ventoux, Mitsubishi 4G1, MeMZ-968, and so on. But my vote goes to the Chrysler flathead straight-six. This engine was produced starting in 1929 and was still being made for stationary industrial use in the early 1970s. It powered just about every type of Chrysler vehicle made for decades, hauled supplies for all the major Allied armies in World War II, and was even developed into a five-bank, 30-cylinder tank engine. It was simple and reliable and outlived most of its competition, and you rarely hear much about it these days. What's your choice?

Fiat Chrysler chief still says EVs can't make money

Add Sergio Marchionne's insistence that it's impossible to make money on electric vehicle production to death and taxes among things we can all count on. The Fiat Chrysler Automobiles CEO, speaking in an interview with UK's Car Magazine, implied that Tesla Motors was "the iPhone of cars." The metaphor may have been mixed, as iPhones make plenty of cash for Apple, whereas Tesla has never made an annual profit from its electric vehicles. But the implication was that automakers should stick to what they know, and they don't know smartphones. Forget any upcoming presidential debates, we're waiting for one between Marchionne and Tesla chief Elon Musk. As for the development of autonomous-driving features? Those are another story, says Marchionne, and an area where he's far more in line with Musk. That's because the technology required to make a car safely accelerate, brake, and steer on its own is far cheaper than making a car with an electric drivetrain that offers similar range and performance to a car with an internal combustion engine, he says. As opposed to electrification, Fiat Chrysler has been going the route of modifying conventional powertrains via wringing out more power out of progressively smaller engines, and mating them with eight- and nine-speed transmissions. As for EVs, credit Marchionne for his consistency. Fiat Chrysler has been selling the Fiat 500e since 2013. That year, Wards Auto named the 500e motor to its 10 Best Engines list, while the 500e won Road & Track's 2013 award for best electric car. Still, Marchionne has long said that Fiat only makes the vehicle for to satisfy zero-emissions vehicle mandates in California, and that the company loses as much as $10,000 for every 500e that it sells.

Fiat Chrysler working on an inline-six to replace the Pentastar V6?

Get out your Skeptics Hat for this one and keep it close by. Allpar cites "reliable sources" to write that Fiat Chrysler appears to be working on a new inline-six engine to be slotted into company products around the globe. The purported engine would be based on the 2.0-liter Global Medium Engine inline-four. Allpar first reported on the potential development in February 2017 and has filed a few updates since then, one citing "internal communications referring to a GME T6" — the "T" meaning turbocharged. It's said that some engineers have changed their online resumes to reflect their focus on the new motor. Apparently, FCA tried adding forced induction to the Pentastar V6 but didn't like the results. The new direction then turned toward a "compact straight-six." In at least one guise, the GME I-6 would come in at just under three liters in order to escape taxes on engines 3.0-liters and above in certain European markets; the 2.0-liter four-cylinder has an actual displacement of 1.995 liters. The present V6 Pentastar comes in 3.2-liter and 3.6-liter guises; a turbocharged 3.0-liter straight-six should be able to replace both as far as output. Hooking up to the company's eTorque system used on the 3.6-liter Pentastar and 5.7-liter Hemi would make things even more punchy. With the trend in truck engine downsizing, it wouldn't be crazy to see such an engine head straight to Ram. The four-cylinder GME unit serves in the Alfa Romeo Giulia and Stelvio, and Jeep Cherokee, Wrangler, and Grand Commander. The big Alfa Romeos and full-size Jeep and Ram models shouldn't have any problem with a longer inline engine. Maserati, which doesn't use the Pentastar engine, could be a candidate as well should it choose to step away from its Ferrari-developed engine cred. Speaking of Ferrari, the Italian brand is working up a new V6 based, in its words, on "a very, very particular architecture." It isn't clear where it will go or if one of the other Italian brands will get access to it, but the Allpar piece says the Ferrari V6 will be based on the core GME architecture for Maserati. Chrysler gave up its last inline-six 11 years ago when the 4.0-liter I-6 retired alongside the JK-series Jeep Wrangler. The engine format is back in vogue, and its reincarnations have received good reviews. But inline-sixes are generally longer, hence FCA's focus on a compact unit, and that could limit the purported engine's placement options.
