According to British weekly Autocar, Infiniti chief Toru Saito is keen to top the brand’s model lineup with a full-on range-topping sportscar. The segment is one which rival Acura had previously attacked with the iconic NSX and which Lexus recently tackled with the LFA supercar (albeit at a stratospheric level), but which Infiniti hasn’t broached until now. Although previous rumors surrounded the use of the Nissan GT-R’s platform, if it comes to be, Autocar says that Infiniti’s sportscar would likely take its cues from the critically acclaimed Essence show car displayed at the 2009 Geneva Motor Show, and possibly draw on parent company Nissan-Renault’s recently-penned partnership with Mercedes-Benz.
