The Bugatti Tourbillon’s extravagant dihedral doors aren’t just for style, they have a functional reason

The new Bugatti Tourbillon is fitted with extravagant dihedral doors.

You’d be tempted to think they were designed just for extra style points, and you’d be to correct.

But, according to Bugatti’s design boss, there’s also another much more important and functional reason.

Dihedral doors are, in essence, a variant of the classic gullwing door.

The name dihedral refers to the hinge because – in a car with dihedral doors – the hinge of the door moves outwards and then upwards.

The reason behind the Bugatti Tourbillon’s dihedral doors

Speaking to CarBuzz, Bugatti’s Director of Design, Frank Heyl, explained the decision to give the car dihedral doors.

The short version of the long story is Bugatti wanted people to be able to get in and out of the car easily and, quoting Heyl, ‘without looking funny’.

The doors incorporate a portion of the roof, and they open up and forward along.

According to Heyl, this is designed to make sure you could get out gracefully.

With ‘normal’ doors, entry into the cabin would have been very awkward.

Everything about the Bugatti Tourbillon is unique

Bugatti took its sweet time to unveil the Chiron successor, but it was worth it.

When Rimac acquired Bugatti, everyone assumed we’d never see a gas-powered Bugatti hypercar again, and the next one would be electric.

But Mate Rimac himself, founder of Rimac and now CEO of Bugatti-Rimac, said that was not the plan.

Then, earlier this year, Rimac proved he meant what he said when he unveiled the new V16 that would power the new car.

With this car, Bugatti thought of everything.

The infotainment screen, for example, is hidden and only comes out when the driver wants it to.

This is because you obviously have to have one, but it sort of ‘spoils’ the overall look, and that’s why Bugatti decided to do it that way.

The bad news is the Tourbillon is incredibly expensive, with a price tag well north of $4 million.

Production is capped at 250 units, and deliveries are scheduled for 2026.
