Car&Driver says that the new Z concept will be based on FR-L platform which is used by Infinity Q60, and it will be a little bit smaller than its predecessor but it will keep the same proportions. Regarding the engine it will have 3.0 l V6 biturbo engine with 400 hp and 500 Nm with a 7 gear automatic transmission with two couplers.
Later on the market it will be available a hybrid version with 500 hp powered by electrical motor i.e. less powerful atmospheric version of the 3.0 V6 engine with 300 hp.
The new Z concept will be out for sale in 2019.
