I suppose it is as Maserati will put it into production regardless of whether we think it is sacrilegious or otherwise. I suppose only the basic underpinnings will be used as according to the press release Maserati claims that everything else; the engine, steering, drivetrain, suspension, exterior and interior styling will be purely Maserati. The still unspecified engine will come from Maranello and will be coupled with an eight-speed automatic transmission. As a result Maserati claims that the end product is "100% Maserati".
I suppose it would be a Maserati. Like any Italian supercar or in this case an Italian SUV, the essence of any Italian supercar is in the engine and an engine manufactured in Maranello, home of Ferrari is truly Italian. If this new Maserati Kubang sounds as glorious as the Gran Turismo or the Quattroporte, no one will care whether or not the Kubang is based on a lowly Jeep Grand Cherokee.
