NHTSA closes investigation on 4.7M FCA power modules, no recall

FCA US hasn't had the best time with recalls as of late. Not only did the company recently agree to greater safety oversight and paid $105 million to the government, that came just days after hacking fears prompted a 1.4-million model recall campaign. However, a recent decision to close an investigation by the National Highway Traffic Safety Administration means that the automaker doesn't have to worry about another major recall possibly affecting 4.7 million vehicles, according to the agency's report (as a PDF). Last September, the Center for Auto Safety petitioned NHTSA to investigate an alleged problem with the totally integrated power module (TIPM) on these FCA US models. The group claimed that a fault with the component could cause a variety of maladies, including stalls, not starting, catching fire, unintended acceleration, and airbag non-deployment. At the time, it also submitted 70 cases where this had reportedly happened. According to NHTSA, "no valid evidence was presented in support of claims related to airbag non-deployment, unintended acceleration, or fire resulting from TIPM faults and these claims were found to be wholly without merit based on review of the field data and design of the relevant systems and components." The agency did find signs of an issue with the fuel pump relay in some Jeep Grand Cherokees and Dodge Durangos, but FCA US issued recalls for the problem in September 2014 and February 2015. Without anything else to go on, the Feds don't think it's worth investigating this topic any more.

SEMA crowns Mustang, FR-S as this year's hottest cars in the building

After wrapping up the first day of the 2012 SEMA Show, organizers handed out awards for some of the trendiest vehicles on display. Since the whole point of SEMA is to show off new products available in the aftermarket world for use in cars, trucks and SUVs, each year, the show distinguishes the most popular vehicle in various segments. Not surprisingly, this year's Hottest Car and Hottest Sport Compact are the Ford Mustang and Scion FR-S, respectively, while the Ford F-Series brought home the Hottest Truck and the Jeep Wrangler was named the Hottest 4x4-SUV.
More than 2,000 companies are at this year's show, and the display booths represents a "vote" for each car to determing the trendiest vehicles in each of the four categories. It isn't clear if these awards also take cars brought by OEMs into account, but the Mustang and FR-S were definitely well represented by both OEM and aftermarket show versions.
As usual, the OEMs showed up in force at the this year's SEMA Show exhibiting a variety of cars ranging from production-intent cars like the beastly Ford Mustang Cobra Jet to much flashier rides like Scion's Carbon Stealth FR-S.

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.
