Interesting comparison here of the Porsche Panamera S against the BMW 550i Gran Turismo.
With the simultaneous launch of the 5-series Gran Turismo and the Panamera, BMW and Porsche have created a new vehicle category. No, the segment doesn’t require the vehicles be ugly, that’s just a side effect. Instead, the new breed is characterized by sporty driving dynamics, luxury equipment, rear-seat opulence, and a slanted back that is as much about style as it is about functionality.
In addition to their physical and philosophical similarities, the BMW 550i GT and the Porsche Panamera S also have a lot in common on their spec sheets. Both cars boast V-8 engines, rear-wheel drive, 400 hp, four seats, and hefty price tags. Looking at these cars raises plenty of questions, so we got behind the wheel for a day of driving through cities, down highways, and over rural back roads in search of some understanding.
