Twitter created a campaign where influencers were at the mercy of their followers, through a global Gumball-style rally. The rally would see three influencer teams (reminiscent of Clarkson, Hammond and May) race across continents while urging their followers to keep engaging to power their individual BMW i3 electric cars on a journey that began in Scotland and ended in Mexico.

Engagement from fans ensured influencers made it to each destination and also promised high-octane content at the world's most infamous automotive tracks / on the road.

Like #thegrandtour itself, the campaign kept mixing it up as it travelled over 10 days. As the teams rolled into new countries, local social media star guests joined in the fun. That not only kept it interesting but these influencers, 21 in all, brought their own legions of fans (hundreds of thousands) to keep the Twitter engagement rolling and ensure the hashtag trended.
