Key Differences
-
The SL has 161 hp more power
The numbers aren’t close. The SL lists 416 hp for total system output, while the 2 Series Coupe lists 255 hp. The SL’s extra output gives it more in reserve when you need to get up to speed.
-
The 2 Series Coupe has better fuel economy
A clear win for the 2 Series Coupe: 30 mpg against 22 mpg. Few specs in this matchup are as one-sided. Official figures rarely match real-world driving exactly, but the ranking between two cars tends to hold.
-
The SL has 74 lb-ft more torque
Here the SL pulls well ahead of the 2 Series Coupe, with 369 lb-ft compared to 295 lb-ft. More torque means stronger pulling from low speeds, which you feel when accelerating from a stop or climbing grades.
-
The 2 Series Coupe has better city fuel economy
The 2 Series Coupe doesn’t just edge this one; 26 mpg against 19 mpg is a lead you’ll feel. City fuel economy matters most if your driving is mostly short trips, traffic and stop-and-go commutes.
-
The 2 Series Coupe has better highway fuel economy
Big gap, real consequences. The 2 Series Coupe’s 35 mpg versus the SL’s 27 mpg changes how the two compare in daily use. Speed, wind and load affect highway use a lot, but the official rating is a fair comparison point.
Design & Size
Engine & Performance
SL leads
The SL is the clear pick if engine & performance is what you care about most. The SL wins here with 161 hp more power. Power is only part of the story; weight, gearing and torque delivery shape how quick a car feels. For engine & performance, the SL is the one to beat.

Fuel Economy & Range
2 Series Coupe leads
For fuel economy & range, the verdict is easy: the 2 Series Coupe leads, and not by a little. The 2 Series Coupe makes its case with better fuel economy. Better combined fuel economy lowers your running costs every week, and the savings add up over years of ownership. That makes the 2 Series Coupe the natural choice for buyers focused on fuel economy & range.
