Its a on new generation JAZZ platform 100 % confirmed. All cross overs are on a sedan/ hatchback platforms. Like Venza is on Camry. and to give you a surprise CRV is loosely related to Civic with around 20 to 30% same parts. Car manufacturer are reducing cost by using same plat form.
Like VW using its new MQB platform which is used in variety of models. Porsche Cayenne, Audi Q7 and VW Tourag share same platform. I have to reconfirm about RAV4, as it sits on Corolla platform.
