You mean as compared to E70 4.8i with sport package?

Both are different beasts and engine is tuned differently. You will know the difference right away.

The gas pedal on 4.8is is very responsive as against 4.8i sport. Different suspension and therefore different handling.

E70 4.8i exhaust note is missing the growl. Don't hear the engine from distance on E70 4.8i.

Although I like the E70 minus the plastic bumpers but after having driven E53 4.8is I don't think I can go back to non-performance version X5.
