Our Hyundai would easily go up to 80 towing. On quiet french autoroutes is easy for it to sneak up to 70! Cruise is useful.
We sit at 60ish where safe and legal as limit is 90kph for our outfit.On the flat its quite happy in 6th gear

No substitute for power!The bigger engine is not working as hard.

I am amazed there are 1.0 eco engines in some quite big Fords. Seem to go ok though.
We have a Mini Cooper too, I am surprised Mini put the 1.5 3 cylinder in rather than a 1.0.
It is a very responsive and sporty little car, pulling well in all gears.

We tried the Cooper SD which is a 2.0 turbo, that was really quick but has a very hard ride.

The concern I would have Monty is longevity. To get so much out of a small engine it must be highly stressed, so how long will it last? It's ok if you can afford to buy new and change it every year, but my cars are always at least 10 years old before I buy them, and usually have around 100,000 miles on the clock. Not a problem with a large lightly-stressed engine. One of my neighbours had a Volvo he used as a taxi, and it was still running well with over 300,000 on it. My Volvo V70 diesel had 186,000 on it when I sold it at 18 years old, and it still ran like a watch. Didn't use any oil, and always started first time winter and summer.

Nothing exceptional, there are lots of high mileage cars and vans on the road with far more mileage than that on them.

Longevity was a concern that hadn't escaped me, but it's an engine that's been in use long enough for any serious weaknesses to have shown up, and I wasn't away of any.

It was bought new and I no longer do high annual mileages, so the need for it to go around the clock once let alone multiple times just isn't there for me. If it lasts 10 years, one way or another, pretty good chance that'll be the end of my driving days. Looks like the days of private cars as we have known them may be coming to an end.

The power output from modern turbo charged diesels, which matches or even exceeds similar sized petrol engines, puts them under extreme stress, but they have proved to be impressively reliable.

One of my old diesel Citroens was sold on to my cousin, reckon that must have done over 200k by time she got rid. It was as good as day it was made when I moved it on at 120k.

Thankfully modern engines tend to be very long lived. I'm old enough to remember when you would consider an engine with 50/60k on it to be just about end of life! - Close to matching every gallon of petrol with a pint of oil!!!!!!

What you cant change is the amount of power/torque needed to move a mass at a given speed, that's simple physics.

30 years ago the accepted norm was that you needed a big 2.8 - 3.0 litre engine to tow. That gradually crept down as cars became more efficient.

No reason why today's smaller engines should be any less effective. They are just way more efficient, in part due to advances in control systems, weight saving & fuelling. Modern control & sensing technology is at a level unthinkable only 10 or 15 years ago, meaning systems run at their absolute optimum.

No reason why longevity should be an issue, they're not running at higher RPM. A manufacturer would be foolish to go to market without putting millions of miles on an engine platform in validation.

Modern R&D utilises tools such as FEA (Finite Element Analysis) for modelling mechanical behaviour, flow geometry, casting & moulding design etc. Ultimately allowing the designer to ensure just the right amount of material goes in just the right place, fuel & exhaust systems can be modelled & perfectly optimised etc.

caravans were very light years ago as well, Most vans were well under 1000kgs now the norm is probably 1500kgs
