The X5 is about 1900 RPM at 100 km/hr in 6th. Is there a turbo lag with the
730d? The X5 has drive by wire and the lag is more that a cable
throttle--it takes some time for the engine to wake after pushing it to the
Many times I wonder if all this high tech stuff is more for marketing than
true performance for the drivers!
The only time I notice a "LAG" is when I emerge from a side street into traffic
- dangerous - but the pickup is fairly quick after about 0.5 sec.
However the petrol 740i does a similar 'cough' sometimes when it thinks about
either dropping a gear or two or actually giving me 300BHP to accelerate in
whatever gear I happen to be in at the time - roundabouts here in the UK are the
major hiccups - I know you don't have many 'roundabouts' in the UK. Not wanting
to start a discussion about traffic management but the only one I have ever come
across is in St Petersburg FL at the end of the bridge going to Clearwater Beach
Have a look on Google maps "Causeway Blvd - Clearwater Beach"
Quite some time ago - early 2000 according to the notes. But remember
their overall figure includes performance testing. Their same figure for a
Prius was 22 mpg. ;-)
But their test route - the second figure - is an attempt to give a good
comparison. Official results don't. And each individual uses a vehicle
differently, and towns vary.

Sweet, thanks a lot everyone for your replies. One more question, does
anyone know the difference in fuel consumption between the 3 and 4 liter
diesels? The price difference for the second hand ones is really marginal,
so still wondering which one to get? :)
Check out the impact on insurancer costs, if any.
If you don't do many miles (say below 10 000 miles p.a.) there won't be a
significant fuel cost difference either.
