Chrysler expecting up to 200,000 9-speed transmissions for 3 models this year

Striving for improved fuel economy, we already knew that Chrysler will begin using a nine-speed automatic transmission in some of its new products this year, but what we haven't known is that volume at which this gearbox will be used. According to Bloomberg, Chrysler CEO Sergio Marchionne has been quoted as saying that the automaker expects to sell close to 200,000 units equipped with this new transmission in 2013. Those gear-rich trannies will be spread out across three models, consisting of the redesigned Chrysler 200, the still-unnamed Jeep Liberty replacement and the Dodge Dart.
This transmission should play a pivotal role in making Chrysler vehicles more competitive in their respective segments. Just for comparison, one of the Dart's key competitors, the Toyota Corolla, still uses a four-speed automatic, and a previous report indicates that the next-generation 200 could get up to 38 miles per gallon on the highway, which is better than most non-hybrid midsize sedans on the market. Marchionne says that the new Jeep model is expected during the second quarter of this year, but there is no word as to when the new 200 or nine-speed Dart will debut, but clearly Dodge would like to have the transmission in its compact yesterday. As for that volume figure, it definitely doesn't seem out of reach since the Dart, Liberty and 200 combined for a total of more than 225,000 units in 2012.
How many more gears can we expect in future cars? Probably not many more, since the CEO of transmission-builder ZF, Stefan Sommer, previously stated that nine speeds was the "natural limit" for transmissions.

Jeep planning on a Grand Wagoneer Hellcat?

Twitter guy and Finder of Things Hidden Bozi Tatarevic scored another gem: an internal ZF document referencing a Jeep Grand Wagoneer Trackhawk. Dating from at least early 2017, the German auto supplier paperwork pairs what would be a 6.2-liter V8-powered three-row Jeep with ZF's 8HP95X transmission. The Jeep Grand Cherokee Trackhawk uses the 8HP95 gearbox, a version of the 8HP90 transmission used in the Dodge Charger and Challenger Hellcats, but built for all-wheel-drive applications and with a choice of gear ratio sets. This doesn't mean we'll ever see a Grand Wagoneer Trackhawk, but it looks like Jeep's been thinking about it. Not only that, but the brand was thinking about it with the just-launched-for-2019 Hellcat engine. The ZF document lists 729 PS for the engine in the Jeep, or a hair shy of 718 horsepower — just one off the figure for the 2019 Charger and Challenger Hellcats. The listed production dates mean ZF planned for a build run of April 2017 to May 2017. The document also mentions the Rolls-Royce Cullinan with two sets of build dates: from January 2016 to February 2016, and from December 2017 to January 2018. That sounds like a run of prototypes, which could be how the Grand Cherokee Trackhawk got included in the paperwork. The document didn't reference any other Wagoneer versions. A Hellcat-powered Grand Wagoneer would make sense. The new luxo-Jeep will be built on a modified Ram platform at the Warren Truck Assembly Plant, and we know Ram's working on a Hellcat-bound Ram 1500 TRX. And the now-iconic engine in an SUV that hopes to become a new icon would be a treat for dealers who wonder if the Grand Wagoneer will arrive too late to succeed. Again, this doesn't mean we'll see anything of the kind. Chrysler also evaluated a 300 Hellcat, but nothing's come of it. And with the standard Wagoneer still several years away — the renovations at the Warren plant aren't due for completion until 2020 — any hi-po version could wait another year after launch, were such a thing to happen.

500+ hp Stellantis 'Hurricane' I6 previews a world without Hemis

After years of rumored development, Stellantis has revealed its new six-cylinder engine family. The 3.0-liter, twin-turbocharged "Hurricane" I6 will offer V8 power, forced induction torque and six-cylinder efficiency in a package designed to fit into any of the company's North American rear-wheel-drive platforms.  What is "V8 power," exactly? Well, in standard output guise, the new I6 cranks out more than 400 horsepower (the specific figure will vary by application) and 450 pound-feet of torque, while the high-output variant is good for more than 500 horses and 475 lb-ft. The final figures will be dependent on the application. We'll save you a little legwork: In current Ram, Jeep and Dodge products, the 5.7-liter Hemi tops out at about 395 hp and 410 lb-ft, give or take, and the 6.4-liter around 485 hp and 475 lb-ft.    This is a clean-sheet design that is only related to the company's turbocharged four-cylinder by some common measurements. The I6 is exclusively direct-injection (no hybrid/port-injection here) and the two I6 variants share 96 common parts, including the block and oil pan design. The differences are found in their internals, intake plumbing, valvetrain components and the turbochargers themselves. Stellantis is not yet ready to share specs or supplier info for the turbos but says announcements will come from its partners soon.  The standard-output I6 has a compression ratio of 10.4:1 and revs to 5,800 rpm. It will run on regular fuel, albeit with reduced performance; 91 octane is recommended for maximum output. The high-output variant has a compression ratio of 9.4:1 and will rev to 6,100 rpm. That one will require premium. The new I6's advantages go beyond basic power output. Every Hemi family engine currently in production is based on an iron block design, so they're heavy. The aluminum-block I6 shaves weight off the total engine package, even if some of that gets added back thanks to the turbos and their associated plumbing. The standard-output I6 weighs 430 pounds, Stellantis engineers told us; the high-output adds just another 11. Fully dressed 5.7-liter V8s are in the 550-560-pound ballpark, and 6.4-liters close in on 600 pounds.  You may be wondering, "Why a clean-sheet gasoline engine now, when the industry is moving toward battery-electrics?" A valid inquiry, and one Stellantis was prepared to address. While the company will be pivoting to electrification over the next decade, it won't be instantaneous.
