Key Differences
-
The C-Class has better fuel economy
At 29 mpg versus 25 mpg, this is a decisive lead for the C-Class, the kind of difference you notice without looking for it. Better combined fuel economy lowers your running costs every week, and the savings add up over years of ownership.
-
The TLX has 17 hp more power
It’s a fine margin, and it favors the TLX (272 hp versus 255 hp). Power is only part of the story; weight, gearing and torque delivery shape how quick a car feels.
-
The C-Class has 15 lb-ft more torque
The C-Class gets a small bonus on torque, with 295 lb-ft against the TLX’s 280 lb-ft. The C-Class’s extra torque makes it more relaxed when fully loaded or towing.
-
The C-Class has better city fuel economy
Small gaps can still matter over time, and here the C-Class leads 25 mpg to 22 mpg. In town, driving style has a big effect, but the C-Class starts from a better baseline.
-
The C-Class has better highway fuel economy
The difference is minor (35 mpg against 31 mpg), but if you’re splitting hairs, the C-Class wins it. Highway fuel economy matters if you cover long distances at steady speeds.
