Many people attending the recent D23 Expo were disappointed that the Matterhorn was closed. The reason was revealed recently. The reason the bobsleds were closed was that new ride vehicles were added to the the ride.
The new ride vehicles have a new paint job and design, and individual seats and seat backs. Guests riding in these vehicles are no longer required to sit two to a seat, with one sitting behind the other. Also, seat belts are being replaced with lap bars.
In the second photo you can see the previous vehicles next to the new ones. Look at the difference. The Matterhorn Bobsleds is scheduled to reopen on September 2.
Thank you Inside the Magic for the photos
