Most bhp per mpg

[tali1]

I don't think there is anybody in the world who can match my rubbish figures of town short journeys driving(which is 99% of my driving)
These are my averages over 20 YEARS
99BHP @ 22.5 MPG -worst from that lot was 60bhp Toyota Starlet @ 17mpg , best was Micra 55bhp @33mpg ( yes 4 of them- all same)
No me neither

That must be one of the dullest things to measure a car by.

Well it's effectively the same as brake specific fuel consumption, which is one of the key parameters that engine designers look at.

I'd argue that mpg per bhp/ton (or mpg per second 0-60 perhaps!) is what you really want to measure for a sports car, but I reckon some indication of economy against performance is very useful. Fuel is sufficiently expensive now that you could rapidly save the cost of a couple of track days you might not otherwise be able to afford by, say, hooning around in, say, an Elise rather than a big thirsty V8.

Corvette C6 Z06 - 505hp - 35mpg on a run (7 litre V8)

Crikey! I thought my tvr was pretty frugal at 28mpg from its 4.2 v8

Do you stop the engines when you go to work, or do you leave them running?

335d (mapped)......seriously

I reckon wait until they crack the BMW 40d unit.

Audi's 3.0TDI is now over 300bhp too.

Definitely handy getting over 400 miles on a tank but having a rather nice wad of power and torque to play with in a 335d ;-)

ps To the nay sayers this is far from dull as a measurement. This is one of my highest criteria for buying a car and possibly the brightest (only) hope for piston heads over the next 20 years.

A. Why would you want a car that was slower and yet uses more fuel?

B. How else are manufacturers going to keep up with tough eco targets and still produce sports models?!

[Vladimir]

Although it sounds like another slightly dull drive, the current S4 is very impressive.

330bhp, a proper 35mpg and about 185g/km. Very impressive.

Petrols are catching up on diesels on emissions/mpg very quickly. And that's from an owner of two soot chuckers!

Trouble is in a 10 mile journey i restart engine about 5 times - i think it would better to leave it running!
But whatever i do makes little difference.

By no means the best, but im still impressed with it

2.3L 300bhp 1430kgs / 30mpg round town, 40mpg on a run

[lowdrag]

At the other end of the scale 310bhp @16mpg gives 19.37. And it weighs but 1.05 tons. No wonder I don't use it as much as I did.

[Niffty951]

mk5 r32 golf was my worst ever. I loved the car but the fuel it drank for its measily 250 hp and poor straight line acceleration was worse than anything else I've ever owned!

[GC8]

My 944 Turbo isnt great, although its better than my MX-5, relatively.

[Captain Cadillac]

My 54 Ford struggles to get 15mpg... with a 130hp 3.9L V8.

And the thing weighs 3,300 or so pounds. Meanwhile my 5200 or so lb 60 Lincoln with a 315hp 7.0L gets 12-13.

[Willhook]

My bike has 4.5hp and does 120MPG
Do I win
=D

[Asterix]

The Porsche 918 when released should be rather good in this aspect.

[B3NNL]

Shirley it would be the Trident Iceni
430bhp, 68.9mpg!

[CraigyMc]

F30 BMW 330d is 258hp and 57.6mpg combined.

[CraigyMc]

Am I totally misunderstanding this?

The "best" power to mpg rating would be a low number, in my opinion. It's the sort of car you want.


eg.

Lambo with 600bhp getting 4mpg would be 150bhp/mpg
OR
prius with 120bhp getting 60mpg would be 2bhp/mpg.

Which would you rather have?
