The 3.6-litre SIDI engine improves fuel economy in the premium models from 7 to 13 per cent. Calais boasts a 12 per cent improvement with fuel economy dropping from 11.2 to 9.9 litres per 100 kilometres on the ADR81/02 test cycle while retaining its luxury features and benefits.
The engine boasts all-aluminium construction and comes in various displacement sizes. The all-alloy construction offers features such as dual overhead camshafts, 24-valve per engine and continuously variable cam phasing. The engines can be used for front, rear or all wheel drive vehicles and are compatible with hybrid electric applications.
The six-speed auto, for both engine variants, employs a ‘turbine damper’ which sits after the torque converter to reduce vibration through the drive-train, further improving refinement.
A new spherical bearing has been fitted to the rear lower control arms, replacing the squishy rubber bushing used by the outgoing model and improving suspension performance under load.
