Rover 75 2 litre diesel verses 2 litre petrol

[triple e]

Hi all,
I have had a 2001 diesel automatic Rover 75 for many years and am looking to change it for a 2 litre 2004 petrol manual Rover 75 which I have yet to see (and drive). Could I request a summary of what differences I would expect from someone with that knowledge please?
Thanks
John

Is it definitely a 2.0 v6 petrol and not a 2.5 v6? The 2.0 v6 was discontinued as a standard option earlier on when the 1.8T was added as a option, although I believe the 2.0 v6 could still be specially ordered in 2004 but it's quite rare to come across one.

If it is a 2.0 v6, expect much lower MPG if that matters to you. Our diesel auto manages 40+ MPG but my old manual v6 struggled to get 25mpg (it was a 2.5 190 ZTT rather than a 2.0 v6).

The v6 is more refined and does suit the car better than the diesel engine. I loved my 2.5 v6 manual and only sold it and replaced it with a diesel due to poor fuel consumption. The 2.0 I've been told is quite sluggish and underpowered compared to the 2.5, whilst not offering any real noticeable savings in fuel economy. Most advise to go for the 2.5 rather than the 2.0. The v6 is better with a manual box from my experience, the autobox on the v6 is not as well suited compared to the diesel.

Check when the belts, water pump and thermostat were last done, as this costs around the £500 mark from a MG Rover specialist garage. The vis motors will most likely need a repair if they haven't been done so already.

the 2004 car may feel not as well put together compared to your 2001 model due to "project drive" cost savings which you may know about already.

I have driven both the 2.0KV6 (company car and also more recently borrowed one) and 2.5KV6 (my own car). All manual.



The 2 litre does have to be driven with "enthusiasm" as it is lower power and is overall a bit more thirsty. My 2.5KV6 returns thirties on a motorway long run.


I have access to a diesel tourer, usual clatterbox on start but of course pulls well.


Personally I would rather be poisoned by petrol than choked by diesel, I hate the smell of diesel and it does make me cough. Thank goodness for the cabin air recycle button when following a diesel vehicle.

Many thanks for the quick responses - I've checked with the seller who has now confirmed his car is as suggested a 2.5 litre petrol with an option fuel available of LPG. This further questions the car - does anyone have experience or suggestion on this combination.
This is complicated but interesting car to consider.
Thanks again for any advice,
John

I've had three 75s or zts with lpg, you have to get the lpg tune just right of the engine management light will show up! Doesn't hurt the way it runs, just annoys you when it happens!

Tunes can be downloaded from any good lpg fitter and installed at home via a laptop and a lead.
