The V12 powerplant is being built by joining two existing 3.6 litre V6 designs in tandem, making them share a single crankshaft. Thus, the new V12 will share the 3.6 litre V6’s technologies such as cylinder shut-off during low load for better fuel economy as well as direct injection. The new 7.2 litre V12 is expected to make over 600 horsepower and 732Nm of torque.
