For the most part, the McLaren OnePlus 6T looks similar to the original 6T, but there are some subtle changes. When it catches the light at a certain angle, for example, an orange rim accents the bottom lining of the phone. On the glossy black back is a striped pattern reminiscent of the carbon-fiber material often featured on racing cars. It's the same pattern seen on the black phone case that comes bundled with the device. Lastly, the phone's charging brick and braided cable (a change from the usual silicone-coated red cord) also have accents of deep orange.

As mentioned earlier, the OnePlus 6T McLaren Edition comes with 10GB of RAM, which is a bump compared to the 6GB and 8GB options that's included with the original 6T.
