We Bought a Brand New 2026 QX80... Then Tuned It Immediately! VR35 Breakdown + Review

Welcome the newest addition to the Racebox fleet! You're probably wondering why Hussain is this excited about an SUV... but once you realize there's a VR35 under the hood, it all starts to make sense. This isn't your typical first-drive or review. We give you a full walkaround of the all-new 2026 Infiniti QX80, cover the features that make it stand out, and then get straight to what we do best. The moment this QX80 arrived at the shop, we got to work. Thanks to our ability to unlock and tune the new MG1 ECU, we wasted no time putting it on the dyno to see what the VR35 is capable of completely stock, then after our custom calibration. If you've been wondering whether Infiniti's newest flagship has hidden performance waiting to be unlocked, this video is for you. This is just the beginning, and we've got much bigger plans for this platform. Want to tune your VR35? Check out our website to purchase a custom tune: https://goracebox.com/products/2025-n...
