Watch this 840-hp Jeep Grand Cherokee SRT8 walk away from GT-Rs and M3s

This last-generation Jeep Grand Cherokee SRT8 does things that SUVs just shouldn't be able to do, like win drag races against tuned Nissan GT-R and BMW M3 coupes. Granted, the owner isn't coming into this fight with a stock Jeep – far from it. In addition to twin turbos whistling away, he says the engine is a 449-cubic-inch V8, which is nearly 7.4 liters of displacement. As it runs here, the driver claims that the turbos are pumping out around 14 psi of boost to give an estimated 840 horsepower. What's more, he further maintains the powertrain could reach around 1,200 hp with things fully cranked up. Even somewhat dialed back, this Jeep is ready to take on a breadth of formidable challengers, including a couple of Chevrolet Corvette models and a Lamborghini Aventador. Check out the video to see how this menacing Grand Cherokee fares in a day at the races.

FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.

Chrysler highlights Mopar lineup for SEMA

SEMA is all about aftermarket parts, and in Auburn Hills that all comes down to one name: Mopar. After having previewed its lineup for this year's Vegas tuner expo earlier this month, Chrysler has now revealed what may not quite be its full dossier of modified show cars, but a good portion of them.
All told Mopar is preparing 20 vehicles for display at SEMA this year. Among them you'll find the Ram Sun Chaser, a 1500 Quad Cab show truck kitted out in two-tone orange and black paint, a roof rack for surfboards, onboard shower and convertible tailgate. The white Fiat 500L is called the Adventurer and is modified for a more rugged look that could hint at the upcoming crossover version. The Jeep Cherokee Trail Carver upgrades on the Trailhawk package with everything from roof basket to rock rails. To counterbalance the off-roaders, there's also a modified Chrysler 300S with a deep black paint job, special grille, Varvatos-edition wheels and more.
All four concepts details so far have Katzkin interiors as well, and there's also an unspecified Dodge Durango with a storm-trooper look in the gallery above. But for more details on what Mopar has installed on the Ram, 500L, Cherokee and 300, you'll want to delve into the press release below.
