The interior is designed by BMW Group Designworks USA. The cabin typically seats four passengers and can be customised in three seating configuration options: a business cabin layout with two forward and two rear facing reclining leather seats, or an air taxi layout with four forward or six forward facing seats. Each seat is fitted with pilot-passenger communications and a laptop port.
The aircraft is of 20% carbon-fibre composite and 80% metal construction. The Phenom 100 has a low straight wing with a slight sweep on the leading edge, two rear mounted engines and a T-tail.
