Alfa Romeo Stelvio QV

Two buttons add magic. The first is red and ignites the 503bhp fireworks display. The other took a while to find, in the centre of the driving mode selector. Crank that to the extreme settings and the button illuminates. Press it and the dampers soften instantly (to ‘mid’ in Race, ‘soft’ in Dynamic), giving all the naughtiness, without dislodging your fillings.
