2015 Jeep Cherokee finds a bit more fuel mileage thanks to stop/start and aero tweaks

Just a year after it burst onto the scene, Jeep has already made a pretty substantial addition to its V6-powered Cherokee, which has proven to be an extremely popular seller so far for the brand, adding a new stop-start system for the midsize, off-road-ready CUV.
The addition of stop-start included a few aerodynamic tweaks to the Cherokee's polarizing body, resulting in a wallet-pleasing increase in fuel economy. According to the EPA, the front-drive, V6-powered Jeep will now return 21 miles per gallon in the city and 29 mpg on the highway, up from 19 city and 28 highway. Four-wheel-drive, V6-powered Cherokees, meanwhile, will now return 20 mpg in the city and 28 mpg on the highway, up from 19 mpg in the city and 27 mpg.
With 271 horsepower, 239 pound-feet of torque and these newly enhanced figures, it's refreshing to see a larger, naturally aspirated engine that is still able to take the fight to today's crop of small-displacement, turbocharged four-cylinders.

FCA seeking new trial in Jeep fire case, calls $150M judgement 'grossly excessive'

Fiat Chrysler Automobiles is fighting back after a Decatur County, GA jury ordered the company to pay $150 million to the family of a four-year-old boy that was killed after a 1999 Jeep Grand Cherokee crashed and caught fire. The company is requesting the judge reduce the award, and should Walden's family not agree to the lower sum, that a new trial be held. The Detroit Free Press reports that FCA would be forced to pay $120 million over the death of young Remington Walden, with an extra $30 million being paid to the boy's family. Neither figure sits well with the automaker, though, which called the fine "grossly excessive," and claimed it was in violation of Georgia state law. The judgment stems from FCA's long-running problem with the fuel tanks of certain Jeep models built in the 1990s and 2000s. According to the newspaper, FCA argues that the jury was biased after the Waldens' attorneys played on the their passions and pushed for a big award, saying the wrongful death award was 11 times more than any appeals court has ever upheld. FCA said attorneys for the plaintiffs told the jury to base the settlement on Sergio Marchionne's total compensation, $68 million. FCA also claims in its motion that the young boy's suffering was brief. "A $30-million pain-and-suffering award for what plaintiffs acknowledge was at most one minute of suffering is irrational," the motion, which was obtained by The Detroit Free Press, read. "Where such plainly improper arguments are immediately followed by irrational and stunningly excessive damage awards, there can be no doubt that the jury acted from passion and prejudice." Jim Butler, the attorney for the Waldens, has called the motion "nonsense," although he said the family will accept whatever figure the judge sets.

Jeep hackers return to take over your steering wheel

Last year, security researchers Charlie Miller and Chris Valasek made headlines by remotely hacking a Jeep, killing the transmission and applying the brakes while Wired reporter Andy Greenberg was behind the wheel and driving in traffic. The hack led to a 1.4 million-vehicle recall for Fiat Chrysler and new jobs at Uber's Advanced Technology Center for Miller and Valasek. Despite the cushy new gigs, the two of them apparently aren't done hacking Jeep Cherokees for sport. In their latest exploit, the pair can gain even more control over a vehicle, but it would also be extremely difficult to pull off in a real-world setting. Here's the harrowing part first: Miller and Valasek can do more than just apply the brakes at low speed or cut the transmission this time around. Now they can turn on the parking brake, mess with the cruise control and hijack the auto-parking system to jerk the steering wheel a dangerous 180 degrees while the car is in motion. It looks about as frightening as it sounds: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Although it's not hard to see how that would make for a very terrifying drive, there's a big grain of salt that comes along with it: Miller and Valasek actually used the same model 2014 Jeep Cherokee as the original demonstration, but without the software patch applied. Or, as Wired put it, "imagine an alternate reality," where a fix had never been made. Unlike before, the latest hack requires a physical connection plugging their laptop into the Jeep's OBD-II diagnostic port under the dash. The team also had to update the Jeep with their own firmware to disable some of the car's built-in safety checks before they could get much control. In other words: In order to get hacked, Jeep owners would first need to roll back their car's firmware to an older version, invite someone to remove security features and then also let them ride shotgun with a computer. Or, as Engadget's resident security expert Violet Blue wrote on Twitter, it's sort of a non-threat. This content is hosted by a third party. To view it, please update your privacy preferences.

That said, The Verge points out that it may still be possible to exploit OBD-connected wireless dongles like the Metromile Tag, Automatic Link or other similar devices currently marketed by insurance companies.
