I test drove a 2007 x5 3.0 today and I was very disappointed with the power that it had or actually the lack of power... the SUV struggled to gain speed while getting on the freeway & was very noisy doing so.. also it shifted up & down a few times trying to settle in at fwy. speeds... even oon surface roads, i step on the gas & it just does not go... well it does, but very slowly, until it decides to downshift & slam my head into the headrest! The test drive was bad & I am not considering the 3.0 in its current form any longer... now i have to test drive the 4.8...
PS, anyone else notice that there is a delay or hesitation when you step on the gas from a complete stop?
