2016 Jeep Wrangler to ditch solid axles to save weight?

Hey, Jeep fans. If you think the idea of a funky-looking, car-based Cherokee revival is offensive, have a listen to what might be in store for the next-gen Jeep Wrangler. Automotive News is reporting that as Jeep develops the 2016 Wrangler, weight reduction is a crucial target, and the Wrangler's rugged solid axles could be sacrificed in the name of better fuel economy.
We've already heard the next Wrangler will go on a serious diet using aluminum body panels and an air suspension system, so the idea of a four-wheel independent suspension setup for this OG SUV isn't all that surprising. Besides, it's not like an independent suspension would limit the Wrangler's off-road abilities - just check out the Hummer H1. In fact, it might be the aftermarket parts companies - not Wrangler enthusiasts - who would be most disappointed by such a drastic suspension change, as the article states that the Wrangler's solid axles and coil-link suspension make it the most popular SUV for customization.
There are probably still a couple years before we'll start hearing any concrete details about the 2016 Wrangler, at which time it will be interesting to see how stricter fuel economy and crash safety regulations have been balanced with traditional Wrangler cues like its removable doors and roof and folding windshield. Let us know in the comments below if a Wrangler sans solid axles is any less of a Wrangler.

100,000 Jeep Cherokee models subject to further 9-speed recalibration

It seems that the software problems with the nine-speed automatic gearbox in the Jeep Cherokee continue to mount. The programming already caused multiple development delays and even postponed the Cherokee's market launch by roughly two months. Now, Jeep has issued another recalibration to hopefully assuage unhappy drivers.
According to Automotive News, this reflash for the allegedly jerky transmission covers over 100,000 Cherokees built before May 5, but it's not technically a recall. If owners are having problems and complain to the dealer, they get the new software. Otherwise, they continue with the current version. New vehicles on dealer lots also receive the latest revision to the programming. It takes only around five minutes to install, but technicians need to take the Cherokee on a test drive to adapt the gearbox to the changes.
The Cherokee's transmission software has been problematic practically since the beginning. The Jeep plant in Toledo, OH, briefly idled its second-shift workers last year to take care of the issue. Since the launch issues for the crossover, demand has been strong. Jeep added another 1,000 temporary workers to the Toledo factory to keep up, and sales were on par with the Wrangler in just its first two months.

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.
