The smallest diesel engine available to the A-class W177 is the 1.5CDI95. Indeed, it produced 96 hp on our dyno, on stock software. According to the owner, stock torque is really not that bad at low rpm. Above 3400 it drops fast and becomes a bit useless on the road. Fortunately for us this type of engine, which comes from the Renault-Nissan-Mercedes family, is detuned via software to limit its performance. The true power potential can be unlocked with a little bit of help with its software calibration. We developed an #Etuners Stage1 tune on dyno. Increasing power to 145 hp and torque to 322Nm from 258Nm. By doing so, the car’s active safety is greatly enhanced. An almost 50% gain in engine power.

Do you think that maybe 50hp above stock on a 95hp car is a lot of extra power? We think you can always borrow brake and suspension parts from the more powerful cars of the same platform: From the A250, A350 to the A45S – the A-Class is almighty!

Is that enough to make the car usable or should we aim for a larger turbo and go “the little diesel that could”?
