Hi Eugene,

We’re a bit confused by this one… if you’re talking about the current ‘W213’ E-Class, launched in 2016, then both the E 200 d and the E 220 d have the same 2.0-litre (it’s 1,950cc) four-cylinder turbodiesel. The E 200 d has 150hp and the E 220 d has 194hp. If the E 200 diesel you’re talking about is a very late ‘W212’ E-Class, then it does have 134hp – but from a detuned version of the age-old Mercedes 2.1-litre turbodiesel. And it should also be badged E 200 CDI, not E 200 d. Either way, the W213 generation is a vastly superior car to the W212, so the reason a 134hp diesel E-Class is a lot cheaper than a 194hp diesel E-Class is because the latter is a newer, better model. If you can find a W213 E 200 d with the 150hp engine, it should be fine to go for instead of the E 220 d, as long as you don’t ever use a lot of acceleration.
