What have you done to your car today?

Feathering along and lots of coasting and no more than 55mph. No VTEC (I think the whole journey was sub 2500rpm)

And this is why Petrol really isnt a replacement for diesel despite the absolute hate that it is getting in the corporate world :( That fuel economy is appalling for the performance (and size of vehicle) offered.
 
Just had two bridgestone potenzas on the front ready for the cold weather. Also looking for a Remap which will push it to around 210-220hp. Debating whether i grab a new intercooler while im at it.

Agreed.
 
Performance Honda vtec cars have gearing which is always going to mean higher revs and inherently more friction.

Rubbish for cruising economy. Oddly they are relatively efficient when driving hard. Emissions/mpg is why they went to turbos

My 275BHP Saab managed 42MPG on a 200 mile return trip to Stansted last night but like you said cruise was pretty much on 56MPH the entire way and then you had the 40MPH roadworks on the A14 which helped it up a bit. I am sure a modern petrol could get around 5-10 MPG more.

I had a new 320i as a courtesy car recently and the MPG wasn’t much better than these Type R figures. It was bizarre... a 320d is faster and would be loads better I’m sure.
 
Broke into the 11's! was a fun battle to get there.

Dunno, circa 33mpg from the ST (which is 2012 so at least a generation newer) on a 100 mile run at 65-70 yesterday which has similar power, but I expect to be lighter. I suppose it could creep up to near 40 at 10mph less, but....well just no

Pretty much every 200-300bhp petrol car I've had of a similar size has performed within a 10% margin on economy even going back to my MR2 turbo
 
Nowhere near as much choice here in terms of big engines in fairly inexpensive cars though, but I'm not really surprised there's relatively little difference
 
Its not all about displacement.

My 1.8 4cyl Toyotas averaged 25~MPG. (1300KG/192HP)
My 2.5 6cyl E30 averages 25~MPG. (1300KG/170HP)
My 2.3 5cyl turbo Volvo's average 22MPG. (1450KG/280HP)
My 4.0 8cyl Lexus averaged 22~MPG. (1850KG/290HP)
My 1.6 and 1.8 MX5's all averaged 27MPG~ (1050KG~/130~HP)

Depends how the engine is tuned, how the transmission is geared, the weight and aerodynamics of the car, as well as simple things like how the car makes you -want- to drive.

... I should really get a more economical car. :p

Those aren't great - my truck is around 2230Kg or something w/ 230BHP and I get 30MPG averaged (though other people with the same model struggle to get more than 25-27).

The joys of modern engine technology. :)

Just like Acemastr can average the same MPG as me with a 5.0 V8 with 435HP and weighing in at 2000KG.
 
Surely mpg figures are difficult to compare as people's usage will vary dramatically?

For example my average has ranged from 21mpg to 49mpg over a full tank.

Saab used their own in house ECU's which is very strange for a small company but they were always like that so are very good on fuel for size and power. I was getting 600 miles to a 70 litre tank on the continent which is massive for a petrol estate that can do 160mph if needed.

My car is also very long geared. 5th at 70 you are barely over 2000RPM.

^This. It entirely depends on how it is driven and the type of roads/traffic. Lots of traffic lights, roundabouts, speed humps or just town driving results in horrifically bad mpg, especially if you like to get up to the speed limit in a hurry and drive up to red lights and slam the brakes on.

My 2016 F55 mini cooper S (2.0 192hp) averages just over 37 on my daily commute ranging from 35 - 39. My 1995 saab 900 (2.0 275hp) manages an average of 29 ranging from 26 - 33 on the same commute.

On longer runs going on holiday, the mini has seen 45 and the saab 37.
