Key Differences
-
The 5 Series has better fuel economy
The 5 Series clearly leads on fuel economy (combined), and 31 mpg versus 21 mpg is a difference that reaches well beyond the spec sheet. The 5 Series uses less fuel on the standard combined cycle, which matters most if you drive a lot.
-
The Panamera has 93 hp more power
On total system output, the Panamera posts 348 hp against 255 hp for the 5 Series, a gap big enough to feel in everyday use. The Panamera’s extra output gives it more in reserve when you need to get up to speed.
-
The Panamera has 74 lb-ft more torque
This is one of the widest gaps in the whole comparison: 369 lb-ft for the Panamera versus 295 lb-ft for the 5 Series. The Panamera’s extra torque makes it more relaxed when fully loaded or towing.
-
The 5 Series has room for 5 seats
It’s a small lead (5 seats versus 4 seats), but it’s real, and it goes to the 5 Series. Extra seats mean you can take more people along without taking a second car.
-
The 5 Series has better city fuel economy
The Panamera lists 18 mpg; the 5 Series comes in at 28 mpg. That’s not a rounding error. In town, driving style has a big effect, but the 5 Series starts from a better baseline.
