Bugatti is finally bidding goodbye to the W16 engine after two decades with a striking new one-off hypercar that is set to be the most expensive car the French company has yet built. 

 

Based on the Mistral speedster but with a fixed  glass roof in place of that car’s open top, the Brouillard – French for ‘mist’ – will be the last new standalone Bugatti model to use the firm’s W16.
