How fast is the acceleration of the 550i without Dynamic Handling?
 
It is said that the 550i go from 0-60 in 5 sec. (oooppps, I said 4 sec earlier which is a big typo)

Is this the same for the 550i with and without Dynamic Handling?

I ordered the 550i without Dynmic Handling and just have the default steptronic automatic and I just want to know how fast can this car accelerate.

0 to 60 in 4 sec??? I dont think thats correct maybe the new m5 will reach that

It's right around 5 seconds to 60 with or without Dynamic Handling. The 6 speed manual is supposed to be a little slower.

Sorry, guys...it was a typo about the 4 seconds. I made the correction in the first post.

Thanks for the correction.

Dynamic handling won't have much effect on the 0-60 time; only xDrive would make a noticeable difference.

Car and driver achieved 4.8 seconds with the non-sport auto transmission this month. I would imagine the sport-auto would get 4.7 seconds. X-drive maybe a little faster than that.

doesn't x-drive create extra weight thereby slowing it down?

I think traditionally that has been the case - especially with lesser powered cars like Audis and 325xis. But when you have 400hp on tap, the impact of the weight on the power:weight ratio is negligible and the benefit of being able to deploy the torque to four wheels instead of two is significant.

As an example, according to Porsche:
The 400hp Porsche Panamera S does 0-60 in 5.2 seconds and weighs 3968lbs.
The 400hp Porsche Panamera 4S does 0-60 in 4.8 seconds and weighs 4101lbs.

If you had 200hp and a lighter car like an A4 or a 3 series, then the 133lb difference may affect the acceleration, but at this weight and hp level, the traction level of four wheel drive makes a difference.

That said I still prefer rear wheel drive cars because the handling characteristics are more fun.

In f10 case, the difference in weight is more significant. Do you have numbers for rolling start or 0-100mi ?

No, but here's the official 0-100km/h for German specs F10:
550i -- 5.0s
550xi - 4.8s
