Obviously : xxx HP are in 4k rpms instead of 7k rpms .
Downshift, put the PETROL engine @5000 rpm and push the pedal ....

Sorry for my (bad) english .. I mean that diesel engine have always shorter gear, thus you remain impressed by diesel engine ... But if you have on the side a petrol, it is faster 
I can see what your saying but you still have to extend the engine to extract that performance

This bit I do get. theres no doubting that petrol is ultimately faster in the lower gears and has a higher rev range. But this is my point, peak torque and power are much lower down the rev range than on a petrol. With petrol you have to 'plant' you foot much further to give the car the same twist of speed as a diesel because the power is higher up.
Choose the Steptronic or use the SMG in Drive mode : kickdown

When they hit the US many will be surprised at what they get, don't knock it till you have used one long term.

For the pedants among us I should've not edited out my original additional emboldening of the power ratings for the 530i and 535d when illustrating why a comparison was of interest.
I had hoped that was the blindingly obvious significant combinitorial factor.
I have been proved wrong - not for the first time.

255 bhp / 265 bhp = 96%
265 bhp / 325 bhp = 82%
so would you mind explaining in what way the 545i is the most blindingly obvious comparable? Clearly, a petrol engine revving at 6500+ rpm with roughly the same peak power as a Diesel revving at 4200 is going to have a lower torque. It is equally obvious that it will have a shorter gearing. What is NOT obvious is that the Diesel will outperform it significantly on most dimensions.

The M5 has less torque than 535d ... Thus 535d is faster than M5 ?
Ferrari F430 : 465 Nm
550i : 480 Nm
550i is faster than 430 ?
The 430 does 3.6-3.7s on 0-62 MPH, 550i 5.5s .
0-200 kmh : 12.9s for the F430, 18-19s for 550i .

I would kill for 1 of these.

Why the snotty comments? :'( Perhaps you misread my post? FWIW I suspect that 545/550 owners in the US will be very impressed with BMW's diesels and are highly likely to be potential customers (I'm personally in that category). And I suspect that most M5 owners do quite like the 550, too.
In the UK if fuel prices and stupid depreciation didn't affect buying decisions then I wonder who would've bought a 550i instead of a 535d?
I can't imagine everyone buys a diesel for its lower CO2 emissions (other than getting a tax break).
