I agree with all you say, but maybe a few caveats, not sure Ive ever actually written that word before.
People, you and myself included, say Lotus was never about the numbers, 0-60 etc, but is this true? Did they never care about 0-60 times or could they never actually make a car with a fast 0-60 time, or did they indeed make cars with super car type acceleration and we have forgotten about it?
The original Esprit had a Lotus quoted 0-60 time of 6.8 seconds back in 1976 (7th fastest in the world at the time!), but the reviews of the day found that to be impossible and the true mark was a disappointing 8.1 seconds. Hence, it would seem Lotus was very concerned with 0-60 times if they were quoting them along Ferrari levels, but simply couldn't actually fulfil them. It's not like it would be out of character for chapman to exaggerate things to get his own way

, integrity was not famously synonymous with mr. C.
Later in life the Esprit, in another guise in 2002, accelerated from 0-60 mph in just 4.3 seconds, faster than a Ferrari 360 Spider, but slower than the Porsche 911 GT2 of the time. So, as I said, I am not so sure about this "they have never been about the numbers". They were also a racing team, a very successful one at that and were 100% about the numbers, back in the day, it's just that they got to these numbers in different ways than some other teams, but again, the numbers were critical.
I think personally since before the Proton years, they simply have not had the money to compete with the big buys in terms of outright numbers, so they have logically focused on other things. The Elise was never a very quick car, but they focused on its drivability to get around that and it worked very well. They had a Rover engine, which was not the best of the day and the Toyota unit added later was hardly as good as a ford eco boost or honda engine, IMO.
So I personally think they would LOVE to be about the numbers, but they simply cant get there and I understand that, but again, we expect certain things, all of which you have correctly listed, but for many of us also expect some kind of numbers too. Top speed is of zero importance to me, once it goes past 140 I could not care less and I doubt I will ever get to 140 either! But 0-60 and 50-80 etc are important feelings for me in a car, as well as all the others you mention of course, it all matters, its not just the brains and no figure, its not just the face and figure and no brains like me.
What I dont like, as much as anything else, is to be told a figure and then not to be able to get anywhere close to it. Let's see someone actually do the sprint in the times quoted. It must have been done, or else how do they know and what conditions was it done in and how repeatable is it. In this sense I prefer the porsche modest reporting of figures. If they give a number of HP, you know you have maybe 5% more. if they give a sprint time, you know you can knock about 0.3-0.5 seconds off it. With Lotus its the opposite and this is like the CS approach, building your hopes up, to knock them down.. I'd rather go the other way .......
Anyway, all interesting stuff. I think I would still love to own an esprit one day, although Harry sold his.... hmmm
