There are nine major structural parts that are made from the HPF process, namely: # Reinforcement Front Pillar Upper LH/RH # Reinforcement Centre Pillar Inner LH/RH # Reinforcement Centre Pillar Outer LH/RH # Reinforcement Side Sill LH/RH # Reinforcement Front Pillar Inner Lower LH/RH # Panel Front Pillar Inner Upper LH/RH # Front Impact Beam # Reinforcement Crossmember Dash Lower RH # Crossmember Front Floor Rear LH/RH Proton car models with RESS body structure that have scored the maximum five-star in both the ANCAP and ASEAN NCAP include: the 2012 Preve, the 2013 Proton Suprima S, the 2014 Iriz and the 2016 Persona.
