Alright, about time for the mid-Series prediction for next update! This is just how I'm feelin' about the update personally, after a couple weeks have passed.
We know we're getting four cars in the Playlist, so no Series reward (thank **** for that). If they're being dead-honest there might not be a car pack this update either but I bet there will be, maybe even whatever they had planned for Modern Horizons before now.
But here's what I've been thinkin'; if this theme of 'one theme, then the opposite of that theme in the next update' holds up, then this update will be performance variants of low-rarity cars. I doubt we'll be getting the FL5, unfortunately, so I left it out, but I hope this holds up.
Mass Production, High Performance (or, Fast Common Cars)
Summer: 2021 Subaru WRX (27,000 units produced. We haven't seen the post-facelift WRX in-game yet; with the Yaris being added in Modern Horizons it's clear PG is at least thinking about expanding the Modern Rally class. Tossing this in would make for a good multirole/leaning off-road reward car. Consider this my pick for Headline Car, though.)
Autumn: 2022 Ford Mustang Mach-E GT (The Obligatory EV for this update. 150,000 cars produced in total. We have a Mach-E already in-game but quite frankly that one is a track model; we don't have a real street-legal Mach-E, so... at least you'd get Ford marketing dollars this way, even if it is Yet Another EV SUV to Make Cross-Country Builds Out Of.)
Winter: Hyundai Elantra N (~400,000 seventh-gen Elantras produced as of 2023. We've never had a TCR in FH5 without its street model either already in-game or arriving at some point--look at the Lynk and Co 03+ and the MG MG7. This might be another marketing partner car but honestly I wouldn't mind this one as much.)
Spring: 2023 Porsche 911 GT3 RS (I know the 911 isn't exactly a common car, but... we've gotta get this thing sometime.)
