REUTERS/Rebecca Cook/File PhotoMarch 6 (Reuters) - American carmakers will lean on technology to keep the horsepower wars going among their electric muscle cars, a tectonic shift from the big, rumbling motors of the past. GM and Dodge have both issued timelines to stop selling gas-powered muscle cars and replace them with electric variants that will wear the same badges. Dodge's Charger and Challenger muscle cars will not be made next year, while Chevrolet has laid out plans for an electric Corvette. Brands such as Polestar and Mercedes-Benz (MBGn.DE) have announced optional power upgrades to their sedans that improve acceleration and total horsepower via paid OTA (over-the-air) software updates. Dodge has said it will transition its muscle cars to an electric platform, and is working to differentiate those models.
