Copying... are you guys serious? The X6 opened a new niche segment which has proven a successful gamble, Mercedes only naturally followed up the general idea (= SUV with coupé-like raking roofline) while still giving it a pretty different interpretation as we can see on the profile. Audi will also put a competitor on the market.
Do you also complain about BMW following up the 4 door coupé trend initiated by the CLS?

It is quite ridiculous to blame the 3 German premium manufacturers for copying each other nowadays as they have been doing this for some time already, as well in terms of market segment coverage as in range nomenclature, design gimmicks, on-board technology, customization... Every manufacturer seeking to appropriate whatever makes the others special: BMW pushing forward FWD and xDrive technology, Audi making the next A8 RWD with the help of Porsche, BMW opening the M Performance line and Mercedes the AMG Sport line as an answer to the Audi S line, etc. etc...
