Diesel or Petrol

How big are these engines  the bigger the engines the less revs required to deliver the power,

When I was working the engines we used were delivering 2500 hp at 500 revs or less

but deficient to the tune of two cylinders 😉😉

And still gets 30+ mpg towing? As I said the bigger the engine the less revs needed to generate the the grunt, and the more gears also normally less revs per mph, but all at a higher cost

30mpg towing? Not a chance .... I can get 30 solo though 😂 But my tow car was bought with towing in mind, we have other cars for mpg & lower running costs 😉

My previous merc with a V6 3l engine gradually built up to 26.2 mpg after 8 years. The present  E220 Estate has gradually climbed in 4 years from 26 until on the last trip just over 30. That was  measured brim to brim over 2430 miles towing 1500kg and with the car heavily loaded and a roof box on

but turbo petrol have been around for a while ... 30/40 years ... though they tended to be the sportier versions with turbos that took a while to spool up to speed. SAAB springs to mind

Those were the old turbo petrol engines that were tuned for performance only. Modern ones tuned for economy can easily match the bhp and torque characteristics of a diesel.

But most houhollds with only one driver keep their costs far lower by having less or one vehicle
