While Porsche competes in the realm of super-fast electric vehicles with its Taycan Turbo S, that battery-electric car doesn’t have a turbo, or even an engine, for that matter. But it does have a sibling in the Porsche family with a 640-horsepower twin-turbo engine for real: the 911 Turbo S. Boosted with even more power two years ago, the 911 Turbo S delivers breathtaking acceleration, tenacious road-and-track handling, and top luxury in coupe and Cabriolet (convertible) styles, starting around $230,000.
