Roofbox or ski carrier

Post by AGT » Wed Jan 08, 2020 9:36 am

I am planning a 1,500 mile round trip to ski in Austria. We will need to transport our skis on the roof of the I-Pace and I am undecided between a roof box and an uncovered ski carrier/rack. I have never used a ski carrier/rack before.

Does anyone have any view on the range impact of a roofbox at 110kmh?

Should a ski carrier have less range impact?

I have the pano roof. Is one option likely to be noisier than the other?

All advice appreciated.

Regards
Andrew

Range impact with ski carrier is huge. I would say more than 10% with Norwegian country road speed.
I have a Thule 750mm ski rack.
I would believe that a roofbok is better. Its aerodynamics in its shape. With roofbox you also get more Space for baggage and your skis arent dirty at arrival.
Big price difference through. 120€ for ski rack. 1200€ for a nice looking roofbox..

I have the Thule Evo Wing bars and a pano roof, and they are still pretty quiet at that speed, just a whisper really. The roofbox doesn't have a huge range impact either (5-10%).

However, I found if you increase the speed much above 120Kmh, the range deteriorates rapidly. I think 110-120 is probably about right for a long journey.

Even if you install the bars carefully, exactly following the instructions, you will find that they sometimes loosen at first, so be sure to check that everything is tight at the first couple of stops.

I Concur, about 10% impact on range for longer trips.

Thanks all. That's really helpful.

I can cope with a 10% reduction in range and am probably happier plodding along at 110 kmh.

So, is the view that naked skis on a rack would disturb the airflow more than a sculpted roofbox?

I just completed some journeys with a big roofbox; my target speed was 110-120 though I only averaged about 90-95 due to some traffic. 4 journeys

5 degC, no wind, battery NOT preconditioned
79 minutes
94 km/h average speed
118km
3.76km/kWh

5 degC, no wind, battery already WARM
76 minutes
91 km/h average speed
110 km
3.85 km/kWh

5 degC, 15-20 headwind, battery NOT preconditioned
122 minutes
90 km/h average speed
175 km
3.29 km/kWh

5 degC, 15-20 headwind, battery already WARM
40 minutes
84 km/h average speed
53 km
3.21 km/kWh

About a 15-20% reduction due to headwind on the last 2 journeys
Unfortunately I don’t have any good comparison journeys without roofbox so maybe of limited use for you....

I have some experience with ski carrier and roofbox. In my opinion the roofbox is the better option because a ski carrier creates the most drag and noise. Roofboxes are more aerodynamic.

Roofbox it is.

I like the photo on Thule's site of the Vector roofbox mounted on a Porsche Panamera lurking outside the IceQ restaurant in Solden. Unfortunately, it is a wallet melting £1,350 and I don't think that includes the Porsche or lunch for four in IceQ.

I had more than 10% reduction with my roofbox, closer to 20% for me.
