One tip, don't drive at 40 in top gear with a cold engine!!!
Seriously, the V6's have huge gears, the V6 can accelerate from 40 in top gear quite easily, but not when cold. There's a distinct lack of power in most engines when cold, and you're running it at probably just above tickover.
PLEASE, run in fourth, or better still, third. When hot, you can do 40 in every gear, it sort of gives an idea on how V6's behave.
