Hi all, new to the forum though had my Abbey Vogue 620 for approx 10 years now.

I am looking at a Seat Tarraco as my next tow car primarily because it is the best I can get on the Motability scheme.
The engine would be a 2.0d 150 PS and is specified at Max brakes towing weight of 2300kg.
My concern would be if this is powerful enough to reasonably tow the Vogue which has an MTPLM of 1635kg but is not usually loaded up that much.
Can anyone offer any advice on whether the Tarraco would be a good to car for the Vogue?

Many thanks.

According to 'Carleasingmadesimple.com' website the Tarraca weighs between 1559 and 1770 kg which should be regarded as the suitability for towing - not the 2300 which relates to specific restsrting on hill testing I think. Clearly you are an experienced caravanner, but still the adage of 'the biggest car you can run and the smallest caravan that meets your need' is a good one - and aiming for somewhere between the 85% and 100% of kerbweight makes your caravan between too heavy or very heavy in comparison depending on the car model specifics.

Thanks for the reply Audiorob. I am comfortable with the weights of the car and caravan and don’t believe that will be a problem.
Where I am less comfortable with is the engine power to weight ratio of the combined unit and whether the 150 PS (148BHP) is sufficient to pull the unit.

Throughout the mists of time, the industry has suggested power to weight ratio of 40bhp HP per Ton, and that was in the days when petrol engines needed lots of revs before any useful torque was produced.

These days the majority tow vehicles still have diesel or turbo assisted petrol engines, where the torque band comes in at lower engine revs, so its my guess that a power to weight ratio of nearer 35bhp per Ton will be more than adequate to tow with.

Seat use VW group engines and the 2.0D series have always faired well in towing tests, so I don't think you will lack power with 150.

My Sorento (2004) and Disco 2 only had 138 bhp but were able to pull trailers heavier than yours. It’s not just power but the torque developed and the vehicles powertrain gearing. I suspect being a car derived SUV the Seat has higher gearing than my two beasts above. But as Proj John says VWG engines are well regarded. You could try Towcar.info to see what the predictions look like.

Its not so much the Horse power, it's the torque that the engine is producing which is more important.

I made that point in my second paragraph.

Is there a torque number that I should be looking at to give me comfortable feeling?
The spec on the Seat site says the 150PS diesel has 340 Nm / 250 lb/ft / 1750-3000 rpm.

The engine you have is more than good enough.
