C350 Petrol Sport Saloon or C350CDI (diesel) Sport Saloon ?

Which is smoother, sounds better, ...???

 

I think Petrol definately sounds better atleast imo.

 

I would LOVE to have a C350CDI! Too bad none ever available here...

 

Run into a smilier issue.

I tossed up between the C250 petrol and the C250 CDI.

While the C250 petrol sounded nicer and was marginally smoother at idle I still chose the C250CDI hands down over the petrol!

The torque the diesel produces over the petrol is amazing, the diesel just keeps pulling. It did take me a while to get used to the diesel noise however the instant fuel savings will constantly amaze you.

Good luck with your decision!

 

The 350CDI is the V-6, isn't it? That engine in the E-Class (Bluetec) is quiet and smooth and can reach 37 US miles per gallon.

In general, MB's 4-cylinder diesels have always been noisier and rougher.

 

C350 CDI will have a revised engine in the mid of this year. Torque increases from 510Nm to 620Nm.

 

 

the 350 CDI is a turbo engine and with some tuning can be made a really fast car. it has much more potential then the petrol version.
Diesel only can't give you a good sound

 

Unlike the i-4 diesels, V6 diesels have good sound and the engine is almost as smooth as a petrol plus you will get better fuel economy. On the other hand, the 350 petrol is a much more reliable engine. It is up to you to decide which you like most.
