I purposely asked on the Q7 forums about track times to see how the Q7 stacked against the SS.
Q7 MKII Discussion - Brakes pads front & rear - Hi.. Audi Q7 2017 56k. My Q7 is still with the factory brakes. Since this is expensive and I have not the skills nor the tools, I am thinking of buying OEM parts and take it to a good Indy. I have heard that rotors usually need to be replaced too...

Guy took a bone stock '19 he had on loan from the dealership and got a 14.5@95mph.
2019 Audi Q7 3.0T runs 14.592 @ 95.170 in the 1/4 mile

His personal Q7 with an APR Stage 1 ran a 14.1@99.5mph
2017 Audi Q7 3.0T runs 14.134 @ 99.510 in the 1/4 mile

My SS ran a 14.0@99.8mph at Bowling Green back in 2016.
My SS weighed just over 4,300lbs the same day in BG. I scaled the Q7 at 5,500lbs last spring after I bought it. If the Q7 was a bit lighter it would be an ever better contender I think. Overall though,
I think you can get an SS into the mid 13's without a ton of work (tune, headers, exhaust, intake), but then you're looking at worrying about that 4L65E, and transfer case for limited life. Hell, there are a good portion of guys that can't get them to live behind stock motors, much less modded ones. I put an external trans cooler on mine (behind front left brake duct), and it helped, but I could still spike trans temps into the 240 range with a hard launch or two.
I will say, the Q7 heat soaks WAY WAY worse than the SS did. I had cooling issues with my SS the whole time I owned it (failed head gasket), and it never heat soaked like the Q7 does. First start and run of the day when the charge air cooler is nice and chilled, I bet it's every bit as fast as the SS. Wondering if you've not gotten a cool day with a Q7 being in Florida. Dunno how much experience with boosted engines you have, but that cool dense air adds significant push.....at least as measured on the butt dyno. Nothing better than a good run for donuts through the country roads on a chilly Sunday morning!
Having owned both, I'm not pulling your leg on the power. I bet if we lined up, the SS would put a car or so on me from launch to 30-40mph, and then it would be close to a dead heat to well into triple digit territory. I had my SS lowered on beltech equipment all around. It was better than stok, but still not great. Combined with the better suspension and paddle shifters (with 4 more gears) in the Q7, on the local backroads there is no way the SS would shake the Q7, the chassis in the Q7 is so much more composed.
Coworker and I "compared" my SS with his '16 Durango R/T on multiple occasions. Same story, that R/T runs in the mid 14's stock, and the SS would put a length or so on him from the light, and then it was a dead heat past 100mph. Same backroads, and I couldn't shake him. They're close enough that until you get into instrumented tests it's really hard to find a performance difference. They're legitimately that close. I think a 6L80E, some good dampers, upgraded brakes, and new suspension bushings on the SS...MIGHT....get you closer, but it's still working on a 20yr old chassis instead of a 5yr old chassis.
The Explorer ST was definitely on my radar. I looked hard at getting just an Explorer Sport from the previous body style when I was shopping for the Q7/Durango last year, as the ST was just being released and there weren't many to be found. They were also outside the $40k budget number I set. The big hold back was the lower tow rating of 5,200lbs. I wanted something that would tow a 24ft Yamaha, and I don't think 5k will get me there. I've had an Explorer as a rental/loaner a few times, and I definitely liked the chassis and the interior. The styling is not super, but not bad. I don't like how many of them I see. They're freaking everywhere. I've always owned cars that are "different" or "rare" when I could. Q7 checks that box, Explorer and Durango not so much. The SS, RX8, yellow S10 (rare paint), red S10 (tons of custom work), and a few others were really distinctive vehicles, and I liked that. I will say the GIANT portrait screen in the ST is a sticking point for me. I'm really not a fan of the "iPad on the dash" styling trend as of late. Love how the screen hides into the dash on the Q7. I spend most of my time in the car with the center stack screen hidden. The brakes and wheels on the ST looks great, and I'm sure they perform well. I love the brakes in the Q7, 375mm (14-3/4in) rotors with factory equipped Brembo 6 piston calipers up front. 325's with 4 pistons in the rear. Audi brakes always impress me, and these are no exception. They'll haul the 5.5k lb SUV down from over 100 to 30 with ease and not fade or warp after multiple stops like that. I would expect the ST brakes to be on par with the Q7's. Guy at work has a 3.0T in his F150. Thing feels like it has torque for days, and I LOVE the upgradability of a forced induction engine. I haven't researched it a ton, but have seen some videos of a Flex with that motor running in the mid 12's with just tuning work. I think there is some good potential in that engine for certain. Not sure how they do with a tune AND towing though. Would have to look into that.
Finally.....I'm really disappointed GM doesn't offer a "muscle SUV" to compete at this segment. Clearly it's a winning segment. Take a Blazer and toss a 6.2L in it and make another SS. Maybe a Terrain with the 3.0T from the Caddys? I think they tried with the Tahoe RST, but good grief those things are so giant you'll never convince me they should be the "sporty alternative". If Chevy or GMC has something to compete here I probably would have landed there. I debated finding another SS, but wanted some newer tech (Adaptive cruise, and heated/cooled seats mostly). Also thought about getting an older ('03-ish) Yukon and modding the snot out of it. Drop, wheels, blower, 6L80E, AWD conversion, etc, while it's cheaper than buying new, arguably more fun, I don't have the schedule to make that happen.
