2023 Toyota GR Supra vs 2023 Subaru BRZ (Supercharged) – Head to Head Review!

Even with the 2nd gen’s bump in engine performance, the BRZ/GR86 has been criticized for being underpowered and therefore not a threat to the higher tiers of sports cars. But this example has been supercharged to 300whp with all the supporting mods, so let’s see if it can finally give a similarly modified (stock engine) GR Supra a run for its money.
