As we were saying, there are more powerful cars available for less cash. The Panamera GTS starts at $128,300 and offers 453 hp. A BMW M5 Competition starts at $110,000 and packs 617 hp, while a Mercedes-AMG E63 is available at $107,350 with 603 hp. These cars are not competitors for the Panamera – they're too big and upright and sedan-like – but the $130,000, 600-hp BMW M8 Gran Coupe is. We adore the way the Porsche drives and can appreciate its better balance between straight-line speed and out-and-out agility, but sacrificing 147 horsepower for a $1,700 savings is a tough ask.
