THE Millenia is powered by a 2.3-litre supercharged V6 that works on the Miller combustion cycle which, in simple terms, shortens the engine's compression stroke. The combined result from the supercharger and Miller cycle is strong performance from a relatively small capacity engine and high fuel efficiency. The engine produces 148.5kW of power at 5500rpm and 282.3Nm of torque at 4000rpm. Official fuel economy figures are quoted at 10.5L/100km (city) and 6.6L/100km (highway).
