The problem with how automakers confront hacking threats

More than anyone, Chris Valasek and Charlie Miller are responsible for alerting Americans to the hacking perils awaiting them in their modern-day cars. In 2013, the pair of cyber-security researchers followed in the footsteps of academics at the University of Cal-San Diego and University of Washington, demonstrating it was possible to hack and control cars. Last summer, their research established which vehicles contained inherent security weaknesses. In recent weeks, their latest findings have underscored the far-reaching danger of automotive security breaches. From the comfort of his Pittsburgh home, Valasek exploited a flaw in the cellular connection of a Jeep Cherokee and commandeered control as Miller drove along a St. Louis highway. Remote access. No prior tampering with the vehicle. An industry's nightmare. As a result of their work, FCA US recalled 1.4 million cars, improving safety for millions of motorists. For now, Valasek and Miller are at the forefront of their profession. In a few months, they could be out of jobs. Rather than embrace the skills of software and security experts in confronting the unforeseen downside of connectivity in cars, automakers have been doing their best to stifle independent cyber-security research. Lost in the analysis of the Jeep Cherokee vulnerabilities is the possibility this could be the last study of its kind. In September or October, the U.S. Copyright Office will issue a key ruling that could prevent third-party researchers like Valasek and Miller from accessing the components they need to conduct experiments on vehicles. Researchers have asked for an exemption in the Digital Millennial Copyright Act that would preserve their right to analyze cars, but automakers have opposed that exemption, claiming the software that runs almost every conceivable vehicle function is proprietary. Further, their attorneys have argued the complexity of the software has evolved to a point where safety and security risks arise when third parties start monkeying with the code. Their message on cyber security is, as it has been for years, that they know their products better than anyone else and that it's dangerous for others to meddle with them. But in precise terms, the Jeep Cherokee problems show this is not the case. Valasek and Miller discovered the problem, a security hole in the Sprint cellular connection to the UConnect infotainment system, not industry insiders.

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.

Stellantis reveals STLA Large platform with EV and ICE support

Hot on the heels of a Jeep Wagoneer S teaser and photos of the prototype next-generation Dodge Charger (or Challenger), comes a reveal and details of what will likely underpin both of them: the STLA Large platform. It's one of multiple Stellantis flexible architectures that will be the basis of its upcoming electric cars, and apparently internal combustion ones, too. Stellantis says the STLA Large platform will be for D- and E-segment cars, crossovers and SUVs. In other words, it will be for midsize and large vehicles. For reference, lengths supported will be from 187.6 to 201.8 inches, and width will range from 74.7 to 79.9 inches. It will be highly flexible, too, with Stellantis claiming significant amounts of adjustability in overhangs, wheelbase, suspension placement and powertrain arrangement. The powertrain flexibility is quite impressive. Front-, rear- and all-wheel-drive layouts will be supported. Single- and dual-motor layouts will be on offer. Internal combustion will be available, too, either on its own or as a hybrid. Apparently engines can be fitted either longitudinally or transversely, too. Battery packs with between 85 and 118 kWh of capacity will be offered, with Stellantis claiming that sedan-style vehicles could have a range of up to 500 miles. The packs will also be available in 400- and 800-volt designs. Stellantis noted also that the platform can "easily accept future energy storage technologies when they reach production readiness." This seems to hint that the company is looking at different battery chemistries and maybe even solid-state batteries that could be added more easily in the future. Furthermore, the platform is designed to handle impressive output. Stellantis says that some models on the platform will have 0-to-62 mph times in the 2-second range. Limited-slip differentials for improved power delivery and wheel-end disconnects for reduced mechanical drag are also on the table for this platform. All of these details fit well with the information previously given for the concept Dodge Charger Daytona Banshee and Jeep Wagoneer S. The former was previewed with both battery voltage architectures and a wide range of electric powertrains with between 456 and 670 horsepower depending on specification and upgrades. And that's just for the 400-volt system; the 800-volt option wasn't detailed. We've also seen photos of the Charger chassis seemingly with provisions for gas engines, likely versions of the Hurricane I6.
