Refreshed Chrysler 300 SRT won't be sold in NA

It looks like it might be time to bid farewell to the V8 rumble from the Chrysler 300 SRT - at least if you live in North America. The reported change comes as Fiat Chrysler Automobiles reshuffles its ranks with the Dodge brand, re-absorbing SRT and building its muscular reputation with the Challenger and Charger Hellcat models. Meanwhile, Chrysler is taking a more mainstream approach, and that likely means the end of overt high-performance models from the division for now.
According to Automotive News, the 300 SRT will be discontinued in the US for 2015, but it won't be totally dead. Some right-hand drive markets will still get the brawny V8 sedan next year, a distinction that goes a long way toward explaining some spy shots we've seen recently.
The 300 SRT's North American demise probably shouldn't come as a total shock. In FCA's five-year plan, it says that the 300 is destined for a refresh to be unveiled later this year, presumably at the upcoming Los Angeles Auto Show. There's no mention of the SRT model in the document, though, which seems to signal its end.

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.
