Generally speaking, we think that you could probably count the lovers of premium convertibles powered by four-cylinder diesel engines using just your hands, but we may be exaggerating a bit.
Apparently, certain European countries are actually pretty big consumers of these types of cars, sustaining the recent increase in the existence of such models from various German car manufacturers.
Among those that offer not one, but two diesel four-pots in a cabriolet are Mercedes-Benz, who can give you an E 220 CDI Cabrio, an E 250 Cabrio and even an E 350 BlueTec if you prefer your diesel convertible to have six cylinders.
Now, if one has bought himself a Mercedes-Benz E 220 CDI Cabriolet and secretly craves for something with a bit more oomph from its oil-burner, the only two choices he has is to either sell the car and buy an E 250 CDI Cabrio instead or take it to a tuner to tickle the engine's ECU for more power.
Thankfully, the French from Digi Services are actually experts in modifying engine ECUs for a large array of car manufacturers, among which we can also find Mercedes-Benz.
To make it short, the E 220 CDI Cabrio in the following dyno video was tuned by Digi Services using just the electronic control unit, with the result being that it no longer has 170 hp and 400 Nm (295 lb ft) of torque but no less than 221 hp and 480 Nm (354 lb ft) of torque.
In other words, its owner not only has a faster car now, but his convertible is also one of the fastest four-cylinder diesel drop-tops out there, all while keeping its looks, fuel economy and comfort at the same level as before.
