Pros & cons

Pros

Quiet, refined and comfortable on the highway.
Larger, more luxurious cabin with upgraded materials and a big 11.9-inch portrait touchscreen.
Strong 255-hp 2.0L turbo with 48V mild-hybrid; quick (about 6.2 seconds 0-60) and still around 26 mpg combined.
Earned the IIHS Top Safety Pick+ award (2024).

Cons

Rear-seat legroom is a bit tight.
Requires premium fuel and carries high insurance costs.
Mercedes brand reliability is below average, with high repair costs.
Early redesigned units show 12V/48V electrical faults, including no-start conditions and sudden shutdowns.
Ride can feel firm and bouncy, with a mushy brake-pedal feel.
Touch-sensitive steering-wheel and dash controls are distracting and hard to use precisely.
