Porsche first introduced the Panamera in 2009 at the Shanghai Auto Show, and since then, we’ve seen a plethora of models and updates. The second generation arrived just last year, and now, there’s a new flagship iteration dubbed the Turbo S E-Hybrid Sport Turismo. Put all those names together, and what you’re left with is a twin-turbocharged 4.0-liter V-8 mated with an electric motor, offering both rip-snortin’ performance and plug-in hybrid eco friendliness, as the mood may strike you. The electric motor makes 136 horses all by itself, while the V-8 makes 550 horsepower. Working in concert, they produce 680 horsepower and 626 pound-feet of torque, essentially making this new Panamera one of the most powerful Porsches ever.
