e55, 460 miles, 14 gallons of fuel

As an appreciator of such cars, with all respect & no offence intended, I don't really understand why drivers of high powered cars (which by definition are uneconomical) post mediocre economy figures which most of us get with normal or fast driving

Surely this is not really the point of such cars?

These cars cost more in environmental terms to produce, get through tyres more quickly, use more fuel, etc, etc

Have the cars & enjoy them for the right reasons; I don't think efficiency & ecological reasons can be one of them!

Do they really cost more in environmental terms to produce. I know they cost more to buy. But consider a well specced E320 and a similarly specced E55, except for the engine, virtually everything else is the same.

It always strikes me as funny that ( say ) a six cylinder engine of greater capacity will cost more to buy than a smaller one. One has more metal in the block, the other more metal in the pistons. The effort and time to build the car is the same, but the cost differential is disproportionate.

In environmental terms a hard driven E55 will cost more, but two cars getting 35mpg (say) cost the same no matter how big one engine is or how small the other.

How long do the rear tyres last

The spec of the running gear will not be the same
There will still be more parts in the AMG;
more engine components(plugs, leads, sensors?) & monitoring systems
higher spec ext & int parts
larger & heavier duty components(larger wheels/tyres/brakes/exhaust/gearbox/clutch as standard), which use more materials & will require more energy to transport
Possibly larger oil requirement to fill engine & gearbox (generally is on bigger engines), more brake fluid, bigger rad/antifreeze
?larger servo for power steering
Look at the kerb wts & I am sure the AMG will be the heavier

In environmental terms a hard driven E55 will cost more, but two cars getting 35mpg (say) cost the same no matter how big one engine is or how small the other

Yes, but how often will one hit 35 or even 40mpg in a 55AMG? Compare this to how often one will hit 35-40 in a A160 or a C180. One will be hardly ever, the other will be a lot of the time!

My c200 used to get 35mpg constantly. Thats because i always drove it to within an inch of its life... i really loved that car .

When the E55 in question was mine, I was lucky to get over 10mpg

This thread summarised the real consumption of a few diesel automatic Mercedes I have driven recently.
Fuel consumption is just one factor in why we have a car.
