Question A180 CDI rental in the UK - question about engine ?

By accident, I ended up with a Mercedes instead of a Ford rental car from UK Avis / Budget Rental in London Heathrow.

Because they did not have an automatic transmission car in that size, they gave me a Mercedes A180 CDI at the same price as the Ford at 25GBP per day.

It was nice to be familiar with the interior controls similar to the R350 I drive in the states - except for the right hand drive and left side road driving opposite of what I am used to.

Took me about an hour to remember how to drive thru roundabouts and on the opposite side of the road and car when I used to tour England many years ago....

So for a week I drove a rental A180 CDI which was a blast on the motorways but a tired dog on the streets.

Can anyone tell me if the engine / tranny is supposed to act sluggish when first starting off the line ?

The car felt as if it was lagging when first accelerating out of gear. I tried both E and S modes to see if it mattered.

The Sport mode did make the transmission hold it's gear longer at higher revs than the Economy mode but the take off from the line was still lagging.

At low speeds or from stand still, the car would literally take seconds to just get going like it was revving up.

Is the A180 missing a turbo or supercharger?

On the motorways once speed is reached, the car performed beautifully - torque was good for passing and better than a gasoline based C class we get here in the US.

Comparatively, the R350 even though is quite a bit heavy still can be peppy in sport mode and does not feel as it is laggy.
My diesel BMW in the US has twin power turbos and has no hesitation at all from low speeds or starting off so it must be a turbo issue ???

There is no replacement for displacement

I don't think I have seen A class in real life, so can't give you direct experience, but comparing 1.8l engine to 3.5l engine you are making pricilpal error right there.
