The Subaru BRZ and Toyota GR86 (formerly 86/GT86) are mechanically identical twins built on the same platform, sharing the same 2.4L boxer engine, but differ in suspension tuning, styling, and interior accents, with the BRZ generally tuned for more neutral stability and the GR86 for slightly more liveliness and oversteer, though both offer excellent handling; your choice often comes down to subtle aesthetic preferences and brand feel, notes TractionLife, Cinch, PistonHeads, YouTube, YouTube.
