Hows this?I don't think it's a matter of pattern that dictates what they'll offer, just what the designers think works best with the given design and what's trending during the respective eras. I'm sure it's customary at this point to differentiate basic trims with a basic lip, then to offer something more aggressive as standard for a GT, and then a little extra for things like performance packs and handling packs.
Nowadays, those stupid devil-horned split wings/lips are all over the place. You see them on Ms, AMGs, really all over modern cars now, and now the S650 has them on the performance package cars and DH. It's like they did the inverse of a centrally raised gurney flap.
I'm sure this styling is partly because it's the latest cosmetic trend that sells well (and might prove my distaste of them the minority opinion), and it's probably backed up by some marketing mumbo jumbo in that it places more aerodynamic forces in places that are more efficient, like where air channels more heavily or the fact that they're placed more directly over the wheels (when in reality it probably makes zero practical difference). Some shit that Ferrari did with its split wing designs on its later-era cars.
But to reply more directly to your question, we're most likely going to see several variations of lips, spoilers, and wings.
I can't wait for this split-end look to die out:
PS, Ford has this obsession lately of designing ugly pedestal wing spoilers with chunky central mounting points. All of their wings would look 1,000,000,000,000 times better without those things. Always made the back of PP S550 GTs look so ugly imo.
