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.

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.

Inline-6 Hemi replacement on the cusp of production from Stellantis

It appears that Stellantis is ready to put its long-rumored inline-six into production at its Saltillo, Mexico plant, possibly marking the beginning of the end of Chrysler's long-running 5.7L Hemi V8. But so far, the automaker's American brands have remained mum on where exactly the new turbocharged "Tornado" I6 may land. Stellantis powertrain blog Stellpower (by way of Muscle Cars & Trucks) spotted an entry for a new "GME T6" inline-six engine on the Saltillo facility's web site, suggesting that it was either in production or close to it. That entry has since been removed, but the mystery remains.  We've been hearing tidbits here and there about this new inline engine for years, but this is the first time we've seen anything suggesting its arrival is imminent. Usually, such a significant powertrain update would coincide with the launch of a new product to showcase it. So far, Stellantis has remained mum, even overseas, about where this engine is destined to reside. 2022 model year vehicles are likely off the table entirely.  But while it's common for new engines to debut with new cars and trucks, it's not a universal truth. Ford's Coyote V8 missed the corresponding Mustang refresh by a year, for example, orphaning the 2010 model and its much-needed styling updates with the old 4.6L V8 (and the 3.8L V6, for that matter; the 3.7L Duratec was also late to that party). Even sticking just to Stellantis, the JL Wrangler's powertrains have been a work in progress since it arrived back in 2018. The standard V6 and 2.0-liter turbo-4 debuted at launch; the EcoDiesel, 392 and 4xe all came later.  And 4xe may be the model by which to measure our expectations. Its introduction didn't come completely out of nowhere, but it was rather sudden for what turned out to be such a solid offering. That bodes well for the company's existing Hemi-powered trucks and SUVs. The Ram 1500, Jeep Grand Cherokee and Wagoneer are all strong candidates to receive the new Hemi replacement, as all would greatly benefit from even small improvements in fuel economy. If there's to be a future for the Dodge Charger and Challenger and Chrysler 300, they'd benefit too. And how about a Gladiator with the wick turned up, positioned as its equivalent to the Wrangler 392. Turn that Tornado into a Dust Devil. Don't worry; we've got plenty more where that came from.  Related Video This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

Jeep Wrangler 4xe's hybrid powertrain: Could it be headed to other FCA products?

On its own, the 2021 Jeep Wrangler 4xe plug-in hybrid is a big deal for the brand and the model line. It's the most powerful and most efficient Wrangler by significant margins, and it doesn't give up the off-road capability that makes the Wrangler so special. But another great thing about this hybrid powertrain is its potential to be transplanted into other FCA vehicles. Just to recap, the layout of the Wrangler's hybrid powertrain, front to back, is as follows: engine, clutch, electric motor, clutch, transmission. The engine is the same 2.0-liter turbocharged four-cylinder that's a standalone engine for the Wrangler. The transmission and electric motor are sort of one unit, with the motor and clutch replacing the torque converter of the transmission. And the transmission itself is the ubiquitous eight-speed ZF automatic gearbox. Its transmission code name is 8HP75PH. The ZF eight-speed is available in every FCA product with a longitudinally-mounted engine and rear-wheel drive or four-wheel drive, with variations in the amount of power and torque it can handle. Not only that, but the Ram 1500 and 2500 and the Jeep Wrangler and Gladiator all have powertrains that utilize the non-hybrid version of the 8HP75 transmission specifically. Even the gear ratios for that transmission as well as the 8HP70 used in the Jeep Grand Cherokee, Dodge Durango, Dodge Charger and Chrysler 300 are nearly identical to those in the 8HP75PH. And a Fiat-Chrysler representative confirmed that the transmission portion of the hybrid drivetrain is basically carry-over from the regular 8HP75. So a transplant could be a relatively simple process. As for which of these models would be the most likely to receive the hybrid powertrain first, the Jeep Gladiator and Ram 1500 would seem like good bets, since they likely have the most similar transmissions, and the Gladiator in particular because of its closely-related underpinnings to the Wrangler. Both are also highly profitable trucks that sell well and could justify the development costs of adapting another powertrain. And in the case of the Ram, there's the impending F-150 hybrid to think about. Although Ram isn't going after a fully electric model, a PHEV could be a nice middle ground. A potential limiting factor would be whether the hybrid powertrain would be sufficiently robust to handle heavy payload and towing demands, particularly over longer periods.
