7 months later, Jeep 'trailer hitch' recall still stalled

For the past few years, Chrysler and its CEO, Sergio Marchionne, have gone head-to-head with the National Highway Traffic Safety Administration and its boss, David Strickland, over the government safety agency's request for Chrysler to recall almost three-million Jeep vehicles due to what NHTSA says is a safety issue that has caused at least 51 deaths. After a three-year investigation and Chrysler's initial refusal to issue a recall because it deemed the vehicles safe and built to the day's federal requirements, last summer, the two parties compromised on a "voluntary campaign" to inspect 1.56 million vehicles, those being the 1992 to 1998 Grand Cherokee and 2002 to 2007 Liberty.
Those vehicles were designed with their gas tanks between the rear axle and the bumper, and NHTSA says that in rear-end collisions, damage to the fuel tank has caused fires responsible for those 51 deaths. The compromise reached last summer was that Chrysler would inspect 1.56 million vehicles and, "if necessary, provide an upgrade to the rear structure of the vehicle." Practically speaking, that meant Chrysler would replace aftermarket trailer hitches, but would take no action if a vehicle had a factory-installed hitch or an aftermarket hitch from Mopar.
A report in The Detroit News says the "voluntary campaign" is just now getting under way, with Chrysler saying last week that the design of the replacement part had been finalized and it was tooling up "to deliver the required volume." Seven months later, still in question is whether NHTSA will crash-test the fix engineered by Chrysler, noteworthy because not only did the vehicles in question pass every safety standard necessary to be cleared for sale at the time, there are still questions (to those of us on the outside) as to how the Jeeps at issue fare among their peers in such incidents. Either way, Chrysler and NHTSA apparently still disagree on the efficacy of the remedy itself: the carmaker says it might help in low-speed crashes but not high-speed collisions, a position the NHTSA is at odds with. All of this means the campaign doesn't yet have an end in sight.

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.

Watch this 650-hp Hennessey Jeep Grand Cherokee go from 0-60 in 3.9 seconds

Hennessey Performance Engineering has created an HPE650 package for the Jeep Grand Cherokee SRT fitted with the 6.4-liter Hemi engine. When it leaves the showroom floor it has 470 horsepower and gets from 0-60 miles per hour in 4.8 seconds. When it leaves Hennessey's garage floor after the upgrade it has 650 horsepower - 530 hp at the wheels, according to Hennessey - and gets to 60 mph in 3.9 seconds on its way to running the quarter-mile in 12.6 seconds.
There's more than just a Roots-type supercharger bolt-on, with ported cylinder heads and high-flow headers among the many changes made to the engine. You can watch this pre-2014 facelift silver model prove its spec sheet on the drag strip in the video below.
