F1 concepts: What if Grand Prix teams had to base their cars on super-minis?

Formula 1 kicks off again this weekend after a long, cold winter with no racing.

Come Sunday, Lewis Hamilton, Sebastian Vettel, Max Verstsappen and the rest will be revving their engines and raring to deploy the hundreds of horsepower at their disposal.

But what if their teams - the likes of Ferrari, Mercedes and Aston Martin Red Bull - had to base their F1 car on the smallest and cheapest model from their road car ranges?

Carbuyer decided to find out, and created these bonkers designs, complete with full F1 liveries.

Do you think Hamilton and Bottas would be happy swapping their W09 for the Smart car?
