Today's motor industry is obsessed with reducing consumption...
Forced upon them by evermore stringent legislation...

The legislation is a pain, I agree, but the question is would the car industry have made the incredible leaps it has done over the last few years without pressure from the legislators?
Modern cars are vastly safer, more reliable, cleaner, more economical, more powerful, and easier to service than they were even 20 years ago.
Remember the day when to get even half-decent performance you had to put up with sub-20's mpg? I for one am quite glad those days are behind us, my wallet couldn't stand it.

I found that changing the rear axle ratio made a huge difference to the "drive ability" of the car. (2011 4/4) 40mph in 5th now ok. Rpm increase is only 300 rpm but makes all the difference. & no change to mpg.
Ran the car like that for over a year but having found a tuner (thanks Cain) now had engine re-mapped. Fairly mild but peak torque is now 500 rpm lower with about 10 hp inc. Car now is a great drive very lively & giving me 47 mpg😀
Have been told lots of reasons for the factory set up but IMHO it is a shame. The car can be so much better.

Agreed, but one of the problems of legislation is that artificial targets are often set and it is because of the need to tick the necessary boxes (for pollution, economy or drive-by noise) that mainstream cars often end up with less than ideal gearing and engine mapping. The car passes all the tests but it will not necessarily be cleaner, more economical or quieter in the real world than if it had more useful ratios and a better torque curve. Of course, this does not apply so much to Morgan, whose approach to suppliers must always be "What have you got that we could use?" rather than "We want this specification and at this unit price."

That sounds a very good upgrade , is it possible to just change the final drive or is it necessary to change the whole axle and you could get a limited slip diff at the same time ?

Beneviro,
give her some 10K more km for a good running in. Try 98 or even 102 octane which betters the mid torque on the ti-vct significantly - and therefore makes the use of the 5th gear more usable. At least you can keep in 5ths longer on slight climbing in comparison to use 95 octane.
Yes, some engines benefit a lot of higher octane like this one, others don't care.
In addition, the cheapest solution to get in some colder air is to put an air hose on the airbox. I'm on vacation, but next week I could take a pic or two. It's very easy to install. For me installing the hose was only a test, if something more durable will work, but I kept it and it works till now, currently in Italy on vacation, almost 40 C hot...
Otherwise, the other posts are right, the 5ths is a cruising gear. My little "tuning" was not done, to make her a racing car, but it is a nice feeling to cruise with less consumption and less flooring the pedal in 5th. Must confess I've been running mine for the last 3 months on super unleaded and it makes a big difference to 5th gear as well as generally more spritely acceleration.

I too have an air Scoop fitted + K&N Filter
I use 98 0ctane
This combo makes a noticeable difference - 5th is great too!
With comparatively low mileage I am not worried about the small extra cost of the fuel.
Am v happy with performance but just for fun might try an ECU upgrade - if i do I will report back!!

Absolutely, and sadly it's not restricted to legislation and politics, either. I spend a significant amount of time trying to explain to my business clients that their selection of Key Business Indicators on which company performance will be measured will drive behaviours that might well end up giving them very different outcomes to this they are seeking... Setting appropriate targets takes great skill, insight, and experience, and too many organisations seem to lack the necessary attributes to do so successfully.

I am amazed at the difference in driveability after 15000 miles.
Agree higher grade fuel makes it happier at lower revs.
I have also had a remap and air filter which also helps, but you have to drop a gear if you want to accelerate at a reasonable pace.
