In which we bring you motoring news from around the Web:

• Simona De Silvestro, one of Team Chevy’s IndyCar drivers, got some seat time in the all-new plug-in hybrid-electric Cadillac ELR this week in Michigan. General Motors said the ELR that Ms. De Silvestro introduced was the first to roll off the assembly line at the company’s Detroit-Hamtramck Plant. The ELR is similar to the Chevrolet Volt in that it uses an electric motor to drive the car, with a small gasoline engine used to generate electricity to charge its batteries. G.M. says its electro-Caddy, which is scheduled to go on sale in 2014, has a range of more than 300 miles. (Autoweek)

• Formula One racing team Williams F1 has officially dumped Renault for Mercedes as its engine supplier for next season. Although Williams will use Mercedes’ turbocharged 1.6-liter V-6 engines and Kinetic Energy Recovery Systems in its cars, it will use its own gearboxes. That puts Mercedes engines in the cars of four Formula One teams: Mercedes, Force India, McLaren and now Williams. McLaren, however, is scheduled to make the switch to Honda as its engine supplier after the 2014 season concludes. (Autoblog)

• Tesla Motors announced on Thursday that it planned to implement an expansion of its supercharger network. Currently, there are seven supercharger stations – five stretching from Sacramento, Calif., to San Diego, one near the District of Columbia and another in Connecticut. Tesla expects to triple that number by the end of June and have enough superchargers for Tesla owners to make the trip from New York to Los Angeles by the end of the year. Two years down the line, the company plans to have a network of stations spanning the United States and even push into Canada. (Business Insider)

Chevrolet's refresh for its 2014 Malibu comes only a year after a redesign for the 2013 model.General Motors Chevrolet’s refresh for its 2014 Malibu comes only a year after a redesign for the 2013 model.

• Following a 2013 redesign, the Chevrolet Malibu will get a refresh for 2014. The rush-delivery alteration goes a little deeper than a mere facelift, though. General Motors said the 2014 Malibu would have a roomier rear seat, more powerful and efficient engine options, and improved suspension components and safety alert features. It also seems to take some styling cues from the all-new 2014 Impala. With the Malibu’s refresh coming so quickly after a redesign, G.M. seems intent upon addressing slipping sales in the midsize segment. (General Motors)

• In Italian, “non ti preoccupare” means don’t worry. That’s apparently what Sergio Marchionne, Fiat and Chrysler’s chief executive, is telling the Italian working man concerning the impending merger between the two companies. Although there has been discussion of Fiat moving its headquarters from Turin, Italy – where it’s always been – to the United States, Mr. Marchionne has reassured Italy’s industry minister that Fiat will not cut any jobs in its mother country. According to a report from Reuters, Fiat is Italy’s largest employer. (Reuters)

• You probably don’t think much about what happens to cars after people crash them, but The Chicago Tribune reports that many of them end up in Afghanistan. Cars that fail to meet safety standards in the United States and Europe after collisions are useable in Afghanistan, which has been getting the West’s automotive hand-me-downs for decades. Often, the cars show up at dealership lots festooned with American and European insurance sticker reading “total loss.” (Jalopnik)
