Need more rpm in petrol engine to spool up turbo than in diesel especially in low starting rpm Is what I’ve been told
That would seem to make sense.
Maybe that's why the sequential turbos work well. From what I understand, the first one is lower speed and pressure; the second faster and higher pressure. However the transition from one to the other occurs, it's imperceptible.
The whole combo works well for me. The Everest, while clearly no Rangie or Bentayga, meets all the objectives I laid out in these pages before I bought it last year.
It really is fit-for-purpose for my needs: a relaxed country cruiser, as near to a sedan as can be hoped for, on bitumen; a gun on dirt and off-road; superb fuel economy. For my needs, I struggle to fault it. I just need better tyres - or could that be better luck with tyres?
On our trip last week, the roads in Karijini NP are heavily corrugated in many parts. I was skipping along in the 75-85kph range really quite nicely. My brother was following us in his Pajero Sport. He got out complaining of bad axle-hop. I had no sign of it. We were both equivalently quite lightly loaded (2 pax, an Engel and luggage in the back) as we were staying in accommodation and not camping.
