Ferrari has unveiled a more extreme edition of its SF90 supercar—the SF90 XX—intended to blur the lines between a racing car and a grand tourer. More horsepower has been squeezed from the car's plug-in-hybrid powertrain, and Ferrari claims a zero-to-62-mph time that's 0.2 second quicker than the SF90's, which would put it below the 2.0-second mark to 60 mph. Both a Stradale coupe and a Spider convertible will be built, but in limited numbers; both body styles are already sold out.
