I really think that "tech" gets used too loosely indeed, by me as well. The Macan has LED Taillights, Heated Rear Seats, A/C seats, Air Suspension, PASM, Adaptive Cruise (avail on X4?) and lots of amenities you can't get on an X4. PDK I consider a feat of mechanical technology that X4 can't touch.
Then you have the extremely comprehensive MFD which has performance tech things like Lateral G monitor, even as simple as TPMS that BMW doesn't activate in the U.S for some stupid reason. Then BMW's have things like "Eco Pro" which it's antithesis to Porsche so they wouldn't waste their time, and some models can be had with LCD gauge cluster which Porsche would never do as their iconic mechanical cluster is what rivets the soul as we all have stared at them and their obscenely high MPH and "dreamt about the day".
Things of value that BMW offers tech wise that Porsche doesn't is HUD, foot kick trunk closer and opener (not sure if on the X4) and a less half-a$$ed keyless starter.
Even though I have a hard time calling the Macan's sunroof a true "Pano" since it's too thin to take up the whole roof, the X4 doesn't even have that option.
So what it comes down to is that too many people confuse "TECH" with "INFOTAINMENT". Tech in a way that still allows you to immerse yourself within the passionate and visceral, mechanical elements, the Macan wins. Infotainment, BMW wins (which is why I avoided that package on the Macan).
