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.

Watch Atieva's electric van outrun a BMW i8 and Dodge Viper

A little while back, automotive startup Atieva drag raced its electric van, called Edna, against a Tesla Model S and a Ferrari California in order to compare its performance against known and revered mechanical athletes. Again, the Silicon Valley-based company is putting its prototype up against electrified and conventionally powered performance vehicles on the drag strip. Last time around, Edna, the Mercedes-Benz Vito van equipped with a 900-horsepower, all-wheel-drive powertrain, bested both of its foes. In that showcase, Edna was hitting 60 mph in a little over three seconds. Comparatively, BMW lists the i8's 0-60 time at 4.2 seconds, though Road & Track clocked it at 3.8 seconds, with a quarter-mile time of 12.3 seconds. The Viper does 0-60 in 3.4 seconds. Before you even watch the video above, you can imagine how it will end, as the retuned Atieva Edna rips 0-60 mph in 2.94 seconds. Atieva clocked the quarter mile at 11.3 seconds at 117 mph. It's worth noting that driver skill can have a lot to do with a car's straight-line performance. We've witnessed Viper's elapsing the quarter mile in well under 12 seconds, which means it should be quicker in this test than the i8, if not the Edna. Still, the performance showcased in the video is exceptional. To improve Edna's stats, Atieva says it has used testing data to fine tune its AC induction motors at higher speeds once it got low-speed performance locked in. After testing in the hot California sun, including the race you see above, Atieva drove Edna 90 miles home with range to spare. As for production plans, Atieva will put this powertrain into a sedan slated for sale in 2018. In the meantime, the company will keep testing and tuning its working prototype, and has even invited the public to put their cars up against Edna in future sessions.

Plymouth Rapid Transit System muscle car concepts going to auction

Over the past decade, Chrysler has built a reputation for amazing custom concept cars based on production vehicles for the SEMA Show and the Easter Jeep Safari. But the company's customization tradition has much deeper roots that include this collection of muscle car concepts headed for Mecum's Indianapolis auction this May. The collection includes three Plymouths that were featured in the traveling display called the Plymouth Rapid Transit System, and a Dodge that appeared at the 1969 Chicago Auto Show. The possible crown jewel of these cars is the 1971 Plymouth Road Runner, and that's simply because the car is completely unrestored with just 1,300 miles on the odometer. Apparently the owner of the shop that built the car for Chrysler got it back after the Rapid Transit System tour ended and took care of it until he later sold it to the late Steven Juliano, whose estate is now selling this collection of cars. Like all of these cars, modifications were mainly visual, but they were extensive. A custom nose and headlight lenses were fitted that added six inches of length, according to Mecum. The car's bumpers were removed completely, as were the external door handles. Recessed hood scoops were added to the hood, and the trunk lid was lowered by four inches to create a rear wing. The taillights were given red, yellow and green lenses like traffic lights. But the best additions were molded Road Runner head marker lights. The interior is mostly unchanged, and the engine is a stock 383-cubic-inch V8 with an automatic transmission. It also has power steering and brakes and the Plymouth Road Runner horn, which makes a "Beep! Beep!" sound like the cartoon the car is named after. 1970 Plymouth Duster View 12 Photos Then there's the 1970 Plymouth Duster in the collection with arguably the best paint scheme. It's bright green with groovy "DUSTER" lettering on the hood and various contrasting panels. It's actually the second scheme the car used, as according to Mecum, the car was built for the 1970 tour and then redesigned for the 1971 tour. The paint is matched with color-coordinated wheels and blue and green floral pattern floor mats. There are unique body changes, too, such as the custom headlight housings, functional brake air ducts up front, fake extractor vents above the rear window, racing-style fuel cap and rectangular exhaust. Mechanically, it has a stock 275-horsepower 340-cubic inch V8 and four-speed manual transmission.
