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.

FCA is setting a five-year strategy: Here's how the last one played out

We're slightly more than four years removed from Sergio Marchionne last five-year plan for FCA, a tell-all where the Italian-American automaker divulged its plans for the 2014 through 2018 model years. It was a grand affair, where Sergio told FCA investors that all was right in Auburn Hills, Alfa Romeo and Maserati were making comebacks, and the fifth-gen Dodge Viper received a mid-cycle refresh. You can read every last one of those past predictions right here. We're on our way to Europe to see Sergio's sequel, coming out Friday straight from FCA's Italian headquarters. (Bloomberg reports a plan to expand Jeep and Ram globally, combine Alfa Romeo and Maserati into a single division for an eventual spinoff, and downsizing Fiat and Chrysler. Also, EVs.) But before we arrive in Italy and find out exactly what Marchionne has planned for 2019 through 2023 as his last act as CEO, let's take a minute to tally up the results of his last term based on the same scoresheet we used in 2014. Now, we're only five months into 2018, so much of this — including vehicles like the Ram HD and Jeep Grand Wagoneer — could still debut this year. For those, we'll mark things TBD. We're not going to draw any conclusions or make any objectionable remarks. We're simply going to let the stats speak for themselves.

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.
