The acronym 25d on the BMW 5 Series has often changed meaning over the years. With reference to models produced since 2000, we find several 525d, all turbo diesel, but with profound differences in the engine. Let's have a look at the main engines that this acronym indicates.

Do you have a Maserati Ghibli Diesel? I'm happy for you! I like it, and very much so. How do you define this car? A luxury sedan? A thoroughbred sports car? A prestige car? In my opinion, it is all of these at the same time. In this case, behind the "trident" under the hood, there is a Diesel engine, a courageous choice by Maserati several years ago.

This nifty Audi engine has direct gasoline injection, 4 cylinders with 4 valves per cylinder, and the perfect match: supercharging! This is how the 2-liter TFSI delivers the impressive 252hp at 5000 rpm with a robust 370Nm maximum torque at 1600 rpm.

De-powered. Yes, it has been de-powered in order to be listed as a version exempt from the supertax, so this 3-liter V6 common-rail turbodiesel, which wanted to express itself with other power and torque values, has to keep some of its horsepower harnessed and hidden in the engine management electronics.

Here is another well-performing variant of Alfa Romeo Giulietta, the T-jet 16V 120hp, which is actually one of Alpha Romeo's least powerful turbo gasoline versions. Let's see how it performs and how it can drive after being electronically tuned by SELETRON.
