My concern as an engineer is how long can an engine this small developing that much power last especially with the extended oil changes these modern cars are supposed to survive on?
My guess is the manufacturers dont care as long as they last the warranty period and once they are past that you will be spending your hard earned on keeping them going.
As much as fuel economy is important if you are going to have to fit a new or refurbished engine or turbo every 80k miles what is the point?

Advancement in engines and technology has moved on as each generation of cars develops over the years so a small engine that in the past would be deemed underpowered and kaput at 60k miles in years gone by is more than adequate to power today's cars and have longevity.
2 litre turbo engines of today can outperform the 6.3 and 7.2 V8 engines fitted to your Jensen which were the pinnacle in the 60's and 70's and provide triple the fuel consumption to boot.
Time and technology moves on and proof is in the pudding that these smaller engines are so far ahead of similar sized engines from a generation or two ago.
