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.

2019 Jeep Renegade, Fiat 500X fuel economy revealed, slightly improved

The 2019 Jeep Renegade and Fiat 500X twins each get a new engine option, a turbocharged 1.3-liter four-cylinder. At 177 horsepower and 210 pound-feet of torque, it's substantially more potent than the 160-horsepower turbocharged 1.4-liter engine it replaces, and nearly matches the naturally aspirated 2.4-liter engine for power while beating its 175 pound-feet of torque. But we haven't known until now is how the new engine fares in terms of fuel economy. The numbers are a little tricky to parse, since both the Jeep and Fiat have changed what transmissions are available, as well as what combinations of engine and driveline are offered. We'll start with looking at the Jeep Renegade. It offers both the new turbo engine and the old 2.4-liter engine, but the manual transmission is gone, and the Renegade Trailhawk gets the turbo engine instead of the naturally aspirated one. All the numbers are below. Overall, the new turbo engine coupled with front-drive and the standard nine-speed auto returns better fuel economy than even the old manual-equipped combo. Both all-wheel-drive models do worse, though, with the automatic and the new engine than with the old engine with a manual. The new turbocharged Trailhawk also doesn't do as well on the highway as the old model, but does better in town. Fuel economy is unchanged for the 2.4-liter versions of the Renegade. 2019 Fiat 500X View 11 Photos The Fiat 500X range is simpler to follow, since only one variant is available now: the turbo 1.3-liter engine with all-wheel drive and an automatic. It's not quite as frugal as the fuel-sipping manual, front-drive turbo model from last year, but it does offer noticeable gains over the 2.4-liter versions. All the numbers are below.

Jeep's 3-row crossover SUV caught inside and out

Jeep is continuing to test its upcoming three-row full-size crossover, as evidenced by new spy photos shown above. Though the exterior doesn't reveal much new, we do get our first look at the inside of the new SUV. Unfortunately, the interior is well-camouflaged. We can tell it has the same corporate steering wheel and shifter as found on other Jeeps such as the Grand Cherokee. It also has highly-stylized gauges and needles, with an LCD display between the two main dials. The gauge cluster is interesting with a dial layout that is completely different from the two-row Grand Cherokee and the three-row Dodge Durango, indicating it doesn't borrow much on the inside from those vehicles. The tachometer is clearly visible, too, and it shows a redline of about 5,500 rpm. That redline corresponds with the turbocharged four-cylinder found in the Wrangler, Cherokee, and, in single-overhead-cam form, the Alfa Romeo Giulia and Stelvio. So it seems this big Jeep may have that four-cylinder engine, probably in the twin-cam Jeep iteration. This would also match previous reports, but we're sure if there will be other engine options. Based on leaked images of the SUV, it bears a passing resemblance to the Jeep Yuntu concept that was shown in China in April 2017. Those leaked images also reveal the name "Grand Commander." Many of the leaks and information about the big Jeep have been related to China, but with automakers such as Subaru and Volkswagen expanding into large three-row SUVs, we wouldn't be surprised if the big Jeep comes here, too. We could also see it carrying the old Grand Wagoneer name. Related Video:
