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.

Chrysler 3.0L EcoDiesel V6: Autoblog Technology of the Year finalist

Offering a diesel engine in an American pickup is anything but new - Ford, General Motors and Chrysler all offer excellent and almost impossibly powerful oil-burning engines in their various fullsize trucks. What is new and novel about the 3.0L EcoDiesel, though, is its size, and the variety of vehicles that use it. It's the smallest engine, as far as displacement is concerned, currently offered in a large truck in the US, and, for 2014 and 2015, it is available in the Ram 1500 and the Jeep Grand Cherokee.
Though it may be small, it's got muscle. While 240 horsepower isn't particularly impressive these days, the engine's 420 pound-feet of torque more than makes up for that. The torque rating is even greater force than even the big 5.7-liter Hemi can muster. Chrysler's well-regarded eight-speed automatic transmission makes the most of all that bull-headed pulling power in both the Ram and Grand Cherokee. Chrysler claims the Ram EcoDiesel 1500 can tow as much as 9,200 pounds when properly equipped, which makes it "90-percent of the Hemi with a night and day difference in fuel economy."
Make no mistake; it's that promise of a sizable fuel economy improvement that many long-haul truckers will be most interested in. In the Ram 1500 that we tested for our Tech of the Year competition, the diesel engine costs $2,850 more than the gas-fed V8, and Ram estimates that EcoDiesel buyers will pay off their investment when compared to the Hemi engine in less than three years, which is considerably less time than the 4.5 or so years the average buyer will keep his or her fullsize pickup. The more you drive, the more you'll save, and the math proves equally as effective in the Jeep Grand Cherokee.

Watch a Cayenne Turbo S, Range Rover SVR, and Cherokee SRT drag race

We live in a weird world where high-performance SUVs could win a 60-mile-per-hour sprint against sports cars from just a few years ago. Here, Top Gear sets up a three-way drag race against the Porsche Cayenne Turbo S, Land Rover Range Rover Sport SVR, and Jeep Grand Cherokee SRT, and the results show just how quickly these high-riding models can cross the quarter mile. The Cherokee SRT is the patriotic choice among the three, but it's down on power in this fight. Meanwhile, the Range Rover's menacing growl sounds the best, and the Cayenne Turbo S has the most horsepower. You'll have to watch the video to see which SUV will win this battle. Related Video:
