This is the main difference - stiffer bracing The two Sportivo models - SX6 and ZR6 - get stiffer sports suspension with additional rear bracing, plus 17-inch alloy wheels with Michelin tyres for more assertive handling. They also get bodykits comprising of sports headlamps and rear combination lamps, sports radiator grille, front foglamps, a rear wing spoiler plus front and rear aprons and side skirts. Alloy-look sports pedals also make the Sportivo grades, as do 3-spoke leather-bound steering wheels. The top spec sports model, Sportivo ZR6, gets luxury extras like dual-zone auto air conditioning, black leather seat trim, two front and four rear clearance and reversing sonars, smart entry (including boot release) and engine push button start. The Sportivo ZR6 and SX6 models benefit from the more responsive handling of a firmer sports suspension system. A V-shaped brace keeps the rear suspension towers aligned and provides greater body rigidity for enhanced cornering. Firmer spring and stabiliser bar settings optimise cornering control even further, by reducing body roll and sharpening steering response even further. So you can play this game with nimble handling and greater control.
