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 SRX’s optional Haldex four-wheel-drive system powers the front wheels all the time and sends torque to the rear when more than a dozen sensors suggest that’s advisable. An electronic limited-slip rear differential helps maintain directional stability during spotty traction conditions.
A new, 3.0L direct injected V-6 engine is standard and a new, 2.8L turbocharged V-6 is optional. Both engines employ technology that helps produce strong performance that is typical of larger-displacement engines.
