The new 4.7-litre V-8 petrol engine is more than 5 per cent better regarding fuel economy while increasing power and torque compared to the previous 4.7-litre engine. The new engine incorporates two spark plugs per cylinder (the only Chrysler Group engine to do so, other than the 5.7-litre HEMI), increased compression ratio, improved cylinder-head port flow and revised combustion chamber, valvetrain and camshaft profile. The result is 227 kW , a 30 per cent increase, and 453 Nm of torque, a 10 per cent increase over the previous 4.7-litre V-8 engine.
