I am not an owner but waiting for some CPO tech package sport hybrids to show up later this year or next year. While researching and comparing, especially to my father's porsche cayenne, I noticed how the acceleration and skidpad lateral Gs are great but the braking distance at 188 ft is pretty bad compared to Q7 at 166 and cayenne diesel at 164. While this is a hybrid, I am wondering if there are any brake kits / better brake compounds to help with this shortcoming. I assume better tires would help but still prefer All season tires for this people hauler.

I believe that the longer stopping distances have more to do with the tires than the brakes themselves. On my 2018 Hybrid, I changed to the Michelin LTX and it seems to have made a significant difference. This may be different in the non-hybrid, for the hybrid is using both the mechanical brakes and the regen system to slow the wheels. (Incidentally, the Michelins are also much quieter on rough pavement.)

on top of the tires; one could always opt for a better compound brake pad.

good point, what is the oem tires?

I was looking up on brake pads, and the top notch carbotech pads i use... they dont even make it fof the MDX.. sad. what do you guys use for minimal dusting and better braking?

The OEM tire is a Continental Crosscontact LX Sport. Better brake pads are certainly a possibility, but all tend to have their weaknesses: dust, noise, poor cold friction, rotor wear, etc. But if there are better ones, I'd also like to hear about them. I believe there are other threads on the forum that discuss this.

Was the 188 Ft breaking distance for a 2018 MDX Adv Hybrid? The 2018 Brochure says the Hybrid has larger front disks than the non-hybrid (13.0" Vs 12.6"). The weight for the Adv Hybrid is 4,484 lbs with the Non-Hybrid Adv at 4,267 lbs.

yup same distance for hybrid and non hybrid

I always wonder how how these tests are done with any given reviewer. With the brakes in anti-lock, which places most of the burden on the tire itself? And, comparatively, are they all done on exactly the same road surface, which is significantly what determines the traction? In reading such reviews, which provide stopping distance, g-force, acceleration times, etc., I am always surprised that the road surface and tires are never mentioned. And if you're comparing the C&D stopping distance with figures from other reviews of other cars, tires and road surfaces, I'd say the comparisons are worth close to nothing.

i'd assume they be doing it in the same testing facilities with the same company reviews. btw, the brake calipers on my father's cayenne diesel are massive. so i have no reservations that it brakes 20+ feet better than MDX. I've looked on tirerack and sees that the OEM tires are not really up to par in comparison. I am a big tires fan and will definitely be looking at tire upgrades when i get a CPO sport hybrid

interesting the 2014 MDX brakes 10ft better than the 2017 models hybrid or not.

I don't know how and where they do the testing, and I personally wouldn't make any assumptions. Have you compared the stopping distances reported by Road & Track, Automobile magazine, Alex on Autos or Consumer Reports? I read car reviews all the time that draw conclusions I disagree with or know not to be true. Do you know how much mileage was on the various cars tested? Do you know if the pads had enough time on them to be seated, the condition of the brake pads or the glaze on the rotors? Do you know who was driving the car, and what their reaction times were? Etc., etc. I'm not questioning the possibility that a Porsche has better braking than an Acura, which wouldn't surprise me, but I'm not as convinced as you are. And I certainly wouldn't compare 2014 tests to tests done three or four years later.

im not here to argue whether 164 and or 188 or 178 are the exact capabilities of these cars, what i want to do is investigate the differences and improve upon the braking capabilities of MDX where possible.
Looking at the cayenne oem tire selection, it comes in michelin latitude summer tires / yokohama advan sport max summer tires / pirelli scorpion verde all seasons. 2014 MDX has the michelin latitude tour HP as oem with the coni, while the 2017 has only the conti as OEM. If the comparison are between a summer or max summer tire set up and the touring conti crosscontact LX sport like the MDX, the difference would be huge. even comparisons between the pirelli, michelin latitude which tirerack happens to have, the wet distance braking differential is pretty big.

perhaps having the michelin latitude HP would bring the car more up to par or do summer tires for those who dont go on snow i guess. in terms of actual MDX sport hybrid users who drive them spiritedly, any feedback on the braking would be great

The brakes on the sport are not half bad but I was looking for a option to upgrade the pads as well.
