By that, The Sleuth means that a four-door “coupe” is a definite go and will launch in the summer of 2020 as a 2021 model. Details are sketchy, but the vehicle’s QX55 designation indicates it will be based on the QX50 tall wagon’s platform, but will have a slinkier fastback roofline not unlike what BMW, Mercedes-Benz and Audi have created as offshoots for their respective X4, GLE and new-for-2020 Q3 models. It’s also likely that the QX50’s 268-horsepower 2.0-liter turbocharged four-cylinder engine will be the base powerplant, while a plug-in hybrid system yielding more power along with improved fuel efficiency will be optional.
It appears as though Infiniti will create a four-door “coupe” called the QX55, leading The Sleuth to believe it will be based on the QX50 tall wagon. ILLUSTRATION: INFINITI
