Default Luxury vs F Sport

I'm looking at purchasing a 2015 luxury model and I see that it rides on 19" wheels like the F Sport.

Does this cause the ride to suffer in the same way the F sport does compared to 18" wheels?

Are there any differences between luxury and F sport with regards to Sport + mode?

Does the Luxury have the same size brakes?

Ive read from several sources it's a firmer ride than the base model. Like a lot of other cars do. My wife's cx9 has the bigger rims and it's just a harsher ride than the trim level with smaller wheels.

How much the difference is the wheels versus suspension, I don't know.

The ride quality is not that much different between the two models. Tires also play a factor. Maybe tbe f-sport is a bit stiffer, but it is the sport trim

Sport/sport+ is the same.

Sport+ between luxury and f sport is NOT the same.

Someone here on the forum educated me on the fact that the AVS is indeed different. He posted a link to back this up.

Search and you will find it.

I have a 2015 Luxury with the 19" wheels. I do not consider it a "luxury ride" but it is not too bad. More sidewall will give you a little better ride, but might not handle as well.

Very minor difference between the F-Sport and Luxury trim is one (1) extra driver's seat adjustment.

The base model has 10-way adjustable seats - front edge Up/Down, back edge U/D, Forward/Back,
Recline Forward/Back and Lumbar In/Out.

The F-Sport add the Extension under the knees Out/Back, The Pelvic (below the Lumbar) In/Out
and the best single feature...the side Bolster "wings" In/Out.

To all of these the Luxury seat add a middle of the seat back "hinge" that tips the seat top Forward/Back.

Both the F-S and Lux excel over the base by tying all the special adjustments to the seat memory system.
This is by far the best "marriage saver" feature available.

Both the front seats in the Lux version are 18 way. I think it's only the driver seat that's 16 way in the F-Sport while the passenger is 10-way. My passenger seat also has a memory feature (not sure if all GSs do).

Thanks. I didnt know this. I guess the technology/what the car does mechanically is the same but the effect it has on the vehicle differs between the two trims..

The mechanical suspension components look to be the same, but the electronic control units for the AVS appear to be different.

Whether this is simply a “tune” or something more substantial, like totally different computer hardware... i don’t know.

Except for the rear wheel steering, asymmetric rear wheels & tires, and the front brake rotors & calipers, the Luxury & F Sport have identical part numbers for coils springs, shock absorbers, sway bars, both front & rear, left & right - thus the software mapping of the 9-stage electronic variable valves inside the shock absorbers is different for F Sport models.

Does that mean that with aftermarket suspension the sport+ mode does nothing ?
