Mopar '13 Dart will roll into Chicago next week

We think this officially counts as a tradition. Every year going back to 2010, Mopar has rolled out a limited edition version of a popular product from the Chrysler Group portfolio. First it was the Mopar '10 Challenger, then the Mopar '11 Charger, then last year's Mopar '12 300, and this year it will be the Mopar '13 Dart, which will make its official world debut next week at the 2013 Chicago Auto Show.
Limited in number to just 500 units, the Mopar '13 Dart is no mere appearance package, though the demeanor of the Dart will be murdered out with a gloss black finish, gloss black 18-inch wheels, a set of Mopar blue stripes and a mean-looking Mopar ground effects kit. Likewise, the interior is touched up with leather seats (a blue one for the driver and black hides for the passengers), gloss black and black chrome trim, blue accent stitching, a sport pedal kit and other Mopar interior accessories.
Turning our attention back to the mechanical bits, the Mopar '13 Dart comes with the car's most powerful engine, a turbocharged 1.4-liter MultiAir four (shared with Fiat 500 Abarth) that's paired with a manual transmission. Those big, black wheels get wrapped in low profile 225/40R18 performance tires, and keeping everything in check is an upgraded brake kit with slotted rotors. The steering has also been calibrated for performance, the suspension lowered seven millimeters, and the exhaust tuned for better engine breathing.

Stellantis announces ‘Circular Economy’ business to drive revenue, decarbonization

Stellantis has already announced its plans to reach net-zero carbon emissions by 2038. Today, the automaker has announced a new business unit to help it reach that goal while generating 2 billion euros per year in revenue by 2030. The “Circular Economy” business will help make revenue less dependent on finite, rare and ecologically problematic materials. The Circular Economy model features what Stellantis calls a “4R” strategy, comprising remanufacturing, repair, reuse and recycling. The goal is to make materials last as long as they can, reducing reliance on the acquisition of those precious new materials in the future by returning them to the business loop when theyÂ’ve reached the end of their first life. Through these processes, Stellantis says it can save up to 80% raw material and 50% energy compared to manufacturing a new part. Remanufacturing, or “reman” in Stellantis shorthand, means dismantling, cleaning and rebuilding parts to OEM spec. Nearly 12,000 remanufactured parts are available for customers to purchase. Some remanufacturing is done in-house, and some with partners and through joint ventures. Repair is pretty obvious — fixing parts to put back into vehicles. This also consists of reconditioning, to make a vehicle feel like new. Stellantis boasts 21 “e-repair” centers for repairing electric vehicle batteries.  Reuse refers to parts still in good condition from end-of-life vehicles sold as-is. Stellantis says it has 4.5 million multi-brand parts in inventory. These are sold in 155 countries through the B-Parts e-commerce platform. Reuse also refers second-life options, such as using batteries outside of automotive purposes. Recycling involves dismantling parts and scraps back into raw material form that is then looped back into the manufacturing process. Stellantis says it has collected 1 million parts for recycling in the past six months. Recycling doesnÂ’t get counted in that aforementioned 2 billion euros of revenue, but it does save the company money on acquisition of raw materials. As for batteries, specifically, Stellantis expects this recycling business to ramp up after 2030, when the packs currently in service begin to reach the end of their lifecycle. Stellantis will use its new “SUSTAINera” label to denote parts that are offered as part of its Circular Economy business.

Top torque-to-weight ratios under $100k, $50k and $25k

Horsepower may steal a lot of headlines, but the always-more-complex torque figure is often a critical one for both the workingman and the motoring playboy. The measure of rotational force represents the twist that can liquefy one's tires or haul one's horse trailer. Good stuff.
It follows then, that as with the horsepower-to-weight list that we assembled for you a few months ago, a list of cars that offer the most pound-feet with the fewest pounds to carry, is an interesting one to break down. Sure, there's a big difference in how the torque is applied from a turbocharged six-cylinder in a Swedish luxury sedan and a massive heavy-duty truck's turbo-diesel. But being the car/stat geeks that we are, we think it's kinda neat that those two vehicles rank near each other where torque and weight intersect.
As with the horsepower list, we've given you figures as pounds per every one pound-foot. Again broken down into broad price categories, we've got a mixed bag of 2014 and 2015 models here, too. Every effort has been made to select the most up-to-date prices and specs, and we've also to omitted some '14 cars that won't be re-upped after the ongoing yearly changeover.
