2018 Jeep Wrangler to get 8-speed auto

Remember when the Jeep Wrangler had a three-speed automatic? That wasn't that long ago – as recent as the 2007 redesign – but Chrysler is keen to leave those days behind on the dusty trail. The current model ushered in a four-speed, then a five-speed, but the latest intel indicates that an eight-speed automatic is in the cards. According to a report filed with the Securities and Exchange Commission, and cited by Automotive News, Jeep plans on fitting its eight-speed automatic transmission to the next-generation Wrangler. Chrysler already uses the ZF-sourced slushbox on the Jeep Grand Cherokee, Ram 1500, Chrysler 300, and versions of the Dodge Challenger, Charger and Durango. But according to the SEC filing, the Auburn Hills automaker intends "to use this transmission in all of our rear-wheel-drive vehicles, except for heavy-duty versions of the Ram pick-up truck and the SRT Viper." AN says that Chrysler wanted to slot the transmission straight into the current Wrangler, but it wouldn't fit. Between the transmission and shift to aluminum construction, the next-generation Wrangler promises to deliver a significant reduction in fuel consumption. In correspondence with Autoblog, however, company spokesmen declined to comment on the eight-speed's suitability towards either the current Wrangler or the upcoming one.

Next-gen Jeep Wrangler to pack 300-hp Hurricane turbo four

Fiat Chrysler has been working for some time now on a new turbocharged four-cylinder engine. Dubbed "Hurricane," the engine is now said to produce nearly 300 horsepower. And its first application could be in the next-generation Jeep Wrangler. With that much power coming from such a small engine, the Hurricane would offer an even higher level of specific output than the 1.75-liter engine in the Alfa Romeo 4C – one of FCA's highest-stressed engines – far eclipsing the 4C's 120 horsepower per liter with 150 hp/l. By way of comparison, the latest 2.0-liter, four-cylinder version of Ford's EcoBoost engine produces "only" 245 hp (122.5 hp/l). The 2.0-liter turbo four in the latest Mercedes-AMG CLA45 and GLA45, however, produces 375 hp. To get so much out of so little an engine, FCA will utilize a twin-scroll turbocharger and variable valve timing. That could make it ideally suited towards a compact performance model, but according to Automotive News, its first application could be in the new the Wrangler. The larger 3.6-liter Pentastar V6 produces 285 hp, nearly as much as the Hurricane will. But with a smaller engine, an eight-speed transmission, and aluminum construction, the new Jeep will likely benefit from dramatically-improved fuel consumption. Related Video:

NHTSA closes investigation into Jeep Liberty fires

The investigation that the National Highway Traffic Safety Administration opened into the Jeep Liberty in October 2013 has been closed. NHTSA received two (!) complaints about fires starting in the driver's door, thought to be caused by the master power window switch. The initial estimate was that 80,000 Libertys could be roped into a possible recall, but according to a report in the Detroit News the agency examined records for 425,000 Chrysler products that used the same window switch, including the Dodge Nitro and Chrysler Town & Country minivan.
After canvassing 265 warranty claims related to the master switches, NHTSA concluded that the rate of fires compared to the "large population of vehicles" was rather low, and that there was no trend pattern behind the few issues it did find. Perhaps with that, and the closure of the trailer hitch investigation, the Liberty can finally rest in peace.
