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.

Prosecutors indict three FCA employees in alleged emissions-cheating case

Federal prosecutors indicted three Fiat Chrysler Automobiles (FCA, now Stellantis) employees as part of an investigation into alleged emissions cheating. Charges unsealed on April 20, 2021, accuse the defendants of helping rig the emissions control system fitted to the 3.0-liter turbodiesel V6 used in some models during the 2010s. Prosecutors claim Emanuele Palma, Sergio Pasini, and Gianluca Sabbioni played a determining role in developing a defeat device that allowed the V6 to obtain certification from the Environmental Protection Agency (EPA) while polluting too much in normal driving conditions. Jeep and Ram began making the engine available in the Grand Cherokee and the 1500, respectively, in 2014, but the charges state plans to game the EPA started in 2011. Palma, Pasini, and Sabbioni knowingly mislead federal regulators, the charges claim; they called it "cycle beating," according to The Detroit News. While the three men were part of FCA's research and development department, they started the project while working for an Italian supplier named VM Motori, which FCA purchased in 2013. Pasini and Sabbioni are each charged with one count of conspiracy to defraud the United States and to violate the Clean Air Act, one count of conspiracy to commit wire fraud, and six counts of violating the Clean Air Act. They could spend several years behind bars if they're found guilty. Both are currently in their home country of Italy. Palma's legal troubles are more serious. He was charged with several counts in September 2019, though four wire fraud charges were dropped in November 2020. He lives in Bloomfield Hills, a city located on the far outskirts of Detroit. Prosecutors claim motorists spent over $4 billion on over 100,000 trucks and SUVs fitted with the non-compliant engine between January 2013 and September 2017. FCA has already agreed to pay $800 million to resolve civil claims from the Justice Department, state officials and customers, though it significantly has not admitted guilt. It stressed that "it did not engage in any deliberate scheme to install defeat devices to cheat emissions tests."

Next-gen Jeep Wrangler to pack 300-hp Hurricane turbo four

Fiat Chrysler has been working for some time now on a new turbocharged four-cylinder engine. Dubbed "Hurricane," the engine is now said to produce nearly 300 horsepower. And its first application could be in the next-generation Jeep Wrangler. With that much power coming from such a small engine, the Hurricane would offer an even higher level of specific output than the 1.75-liter engine in the Alfa Romeo 4C – one of FCA's highest-stressed engines – far eclipsing the 4C's 120 horsepower per liter with 150 hp/l. By way of comparison, the latest 2.0-liter, four-cylinder version of Ford's EcoBoost engine produces "only" 245 hp (122.5 hp/l). The 2.0-liter turbo four in the latest Mercedes-AMG CLA45 and GLA45, however, produces 375 hp. To get so much out of so little an engine, FCA will utilize a twin-scroll turbocharger and variable valve timing. That could make it ideally suited towards a compact performance model, but according to Automotive News, its first application could be in the new the Wrangler. The larger 3.6-liter Pentastar V6 produces 285 hp, nearly as much as the Hurricane will. But with a smaller engine, an eight-speed transmission, and aluminum construction, the new Jeep will likely benefit from dramatically-improved fuel consumption. Related Video:
