Gartheiniog

Gartheiniog is the 6th and final stage of the Vauxhall Rally of Wales (and thus the 6th stage of the Mobil 1 BRC and the A8 Championship, as well as the 6th and final stage of the 6th and final Arcade level).

Overview
As described in-game:"The final stage of the Vauxhall Rally of Wales is quite twisty and held in darkness, but committed drivers can still average high speeds. It's tougher than Dyfi, making punctures more likely, but the quicker, flowing sections are a godsend for drivers of underpowered cars trying to make up time lost in the hairpins."
