Yes - our box sits ontop of the bars through its profile - i looked at the alpine one and see the sloping design - i would go to a retail store where you could try a couple, but there is slope forward on the taycan, so think it would work.
I was looking at the Vector alpine too. Problem is it weighs 30 Kg. The roofbars will also weigh something like 5 ?? Kg. Max roof top weight is 75 kg including box and bars. So the leaves only 40 kg for luggage. That doesn’t seem like a lot. I don’t know what other roof boxes weigh.
I always use rough math for this stuff.. is the weight for structural integrity in normal use or in extreme cases like an accident? i would think its more accidents and im always thoughtful in what i pack and how i distribute the weight.
Just ordered these too and a Vector M ski box. I hope my car will be there in time to test them during ski holidays.Me too, just got mine today.
So much easier to install than OEMs.
I love the looks in silver as it constrast well with black pano roof.
pictures to come.
Use the Thule configurator to get the right set.
I have the 9585B set. Put it on this weekend. The set has two sizes of bars. I thin a L in front and M in the back. The fixation is with rubber straps with a thin metal core. I do t think they will scratch. I have the Thule Vector M. It not very big but it looks really good and I was afraid a bigger box would be worse for economy. Don’t have the opportunity to put the box on. But Thule confirmed it would fit and I measured with my fingers and I think is will. Should have a bit more than 2 fingers between the roof and the bar.
The pictures I posted is the Vector M on our Mazda 3.
It’s been well discussed in other threads here. IMO you can expect 15-20% range reduction under otherwise same conditions, but it’s going to vary based on your particular roof bars and box. In my case I have the Thule aero bars and the Porsche Performance Roof Box. I use the roof box for winter ski trips, so there is also cold weather range reduction. Last winter was my first outing with my CT4, bars and box. I did not get too scientific about it - I did fine with a +20% safety factor on arrival charge in route planning. Keep in mind that the PCM nav doesn’t know about the roof box so it will underestimate consumption for a given route plan in your first few trips with the box on. ABRP has support for car profiles with/without roof box so you can double-check routes with that fudge factor built in.
Thx that is useful info. If have read about the 20% reduction indeed. Kind of hoped the Vector M could be on the lower side because it is quite small low and aerodynamic.
Regarding the smaller gap with the Thule low profile bars - yes, clearance is fine for the PPRB claws. About 3cm from memory. I place a towel over the panoramic roof when installing/uninstalling to avoid any potential scratches.
