Key Differences
-
The AMG GT has 161 hp more power
Of all the specs we compared, this is one where the AMG GT makes its strongest case: 416 hp against 255 hp. More power helps with merging, overtaking and climbing hills, especially with passengers and luggage on board.
-
The 4 Series has better fuel economy
The 4 Series clearly leads on fuel economy (combined), and 31 mpg versus 22 mpg is a difference that reaches well beyond the spec sheet. The 4 Series uses less fuel on the standard combined cycle, which matters most if you drive a lot.
-
The AMG GT has 74 lb-ft more torque
On torque, the AMG GT posts 369 lb-ft against 295 lb-ft for the 4 Series, a gap big enough to feel in everyday use. More torque means stronger pulling from low speeds, which you feel when accelerating from a stop or climbing grades.
-
The 4 Series has better city fuel economy
This is one of the widest gaps in the whole comparison: 28 mpg for the 4 Series versus 19 mpg for the AMG GT. Hybrids often shine in the city, and the 4 Series has the better rating here.
-
The 4 Series has better highway fuel economy
The AMG GT lists 27 mpg; the 4 Series comes in at 36 mpg. That’s not a rounding error. Highway fuel economy matters if you cover long distances at steady speeds.
