Probably a daft M6(/M5) question!

[jonlwright]

Had the M6 about 2 months.

Always use it in 'M' mode set to P500 Sport.

Just wondering if using the 400 mode actually makes it any more economical for local running about?

Anyone actually tried it? Haven't bothered myself as I feel that if it wasn't, I would have been robbed of the extra power for no benefit!

Never found a difference with the E60 M5.

Subsequent discussions with a tuner at VMAX backed up this finding.

[derestrictor]

I don't know; I'd have thought it might make a marginal difference simply due to the likelihood of driving styles encouraged per setting.

Frenzied axe attack v slightly lower key, latent sociopathy.

[jonlwright]

Anyone any idea what the point of P400 is then?

[dazren]

Wife mode?

Ah ha - not thought of that one

On a more serious note, I'd say having the P400 is a useful option for bad weather driving etc.

I actually found P500 more economical since I was on the throttle less.

Is the throttle quite sensitive in P500? Bearing in mind it doesnt have much travel yet has 507bhp to deliver smoothly.

Mine tends to bunny hop a little in traffic sometimes in 500 mode - it doesn't seem to in 400.
I leave it in 400 if trundling through town, just in case it makes a difference to the economy (it claims it does in the manual). I I've to say I've never noticed any difference in its average mpg figures though.

There are 2 500hp modes - P500 and P500 sport. In P500 mode the throttle is quite linear and has alot of travel. In P500 Sport mode it is mapped much more agressively making it quite sensitive. As always with these things, you soon get used to whatever mode you travel in and your driving style adjusts to suit. It's a bit like the sport button on the E46 M3.

For some reason the UK never got a manual version! Even though there are probably 80% manual drivers in the UK comapred to 80% Auto drivers in the US??? Sure there must be a technical reason.

Anywsy - good point on the round town driving in traffic - I might give that a try.

I just thought that the reason it has the 400 option was to be a little more gentle if the accelerator did not have much travel, was just a thought.
