You could put on aluminum wheels 5 1/2 x 14 from a 1981 240D. That would change your wheel weight from 23 pounds to 11 pounds. Reduce weight in other ways. Take that York compressor that is under the hood and throw it in the trash - you'll never use it, I promise. Short of a much-needed engine swap, I don't think you are going to be able to do much to improve the performance of a 220D.

Yes I was already thinking of putting lighter wheels, but I don't know if I like the idea. I would definitely gain some weight*… also I removed the whole asphalt that was inside, I put it all in a big bag, and it's quite heavy. A lot of kilo's in there. I won't be putting asphalt again in the car because there's water that gets underneath and then stays there. Instead, I'll put something like Dynamat. It's expensive, but I want a really quite car, and I can remove this easily if necessary. And it's not heavy at all apparently.

And I won't be changing the engine, this engine is perfect for my use because the consumption isn't too high and I can still keep up with the traffic in the city.

Don't understand your comment about gaining weight, but I realize now that you are in Europe and the aluminum steelies were never on cars in Europe. So unless you want some really expensive shipping bill, keep the wheels you have. If you can keep up with traffic in the city, then what exactly are you trying to fix? Sounds like you have the perfect car for your situation.

Oops… losing weight I meant.

There's no problem with the car, I created the thread because I was wondering if I could be driving on highways in Europe comfortable or not. The allowed speed here is 130 km/h and the car's top speed is 135 km/h, but at 4369 rev/min, so that's pretty high. My family owns some vacancy homes a few hours from where I live, and I thought I could be going there with the 220D once it's finished. But I realise I'd need more than a few hours because I won't be driving at 135 km/h non-stop. It would ruin the engine, to have it run for hours so high. But like I said, 95% of the time I'll be using the car in the city

You could drive less than 130 km/h.... Just an idea...

Yeah, that's what I'll be doing if I don't want to ruin the car. That's why I said it will take me more than a few hours to get there.

I have to see if my TomTom can be set so that the maximum speed I'll ever drive is lower than 130 km/h, otherwise I will always get wrong information about when I'll arrive at which place!

Putting to much diameter with larger tires can and will cause vibration issues

Mercedes engines were designed to run at high rpm's all day long.

Driving a few km/hr slower will only add 10-15 minutes to your travel time.

Yes, I heard that old MB diesels should be pushed. But does that also count if I drive for hours? Do you think it could damage the vehicle?

As for the time, it does make a big difference. If I was driving 135 km/h non-stop for 507 kilometres (the distance to our vacation home), it would take 3,7 hours to get there. If I drove only 100 km/h (and at that point the engine is also revving pretty high), it would take me 5,07 hours.

Do not drive the car at top speed WOT for more than a few minutes! I owned one and when I first got it, the poor car could not get out of its own smoke cloud. By the time I had changed all fluids and filters, taken care of the deferred maintenance, and put a few thousand highway miles, she was able to hit top speed. She was much happier at 120 kph, but did travel fine at 140 for a kilometer or two.

You do want to drive it like you stole it. Italian Tune ups are needed, and puttering around town should be limited. My car was a stick shift, with no AC, no Power anything. Manual locks and windows, no sunroof. BASIC car, as light as the factory could make it. At 135 kph, the car SCREAMS and will demand you slow down a bit. Drive for four hours and a bit at under 130 kph
