Mercedes powers this sports sedan with two engine options with one being petrol and the other a diesel unit. Its petrol avatar is equipped with a 2.0-litre heart which pumps out an impressive 183 hp of peak power at 5500 rpm along with 300 Nm of peak torque available at as low as 1200 rpm. Its petrol unit is a great performer on the roads and it also doesn’t shy away from making occasional trips to a race track. Take it onto a controlled environment (race track preferably) with traction control OFF and you can have most of the fun driving this CLA avatar. On the other hand, its diesel sibling comes to life with a 2143 cc inline four cylinder engine that manages to deliver only 136 hp at 3600 rpm along with a maximum torque of 300 Nm between 1600 rpm. Both the diesel and the petrol avatars, gets top of the line Mercedes 7 speed dual clutch automatic transmission with different driving modes (Economy, Sports and Manual), that helps in swift gear changes and further also adapts the suspension set-up as per the driving environment. The diesel engine here clearly lacks punch but is a more frugal engine.
