It deactivates four of the cylinders on the V8 engines and two cylinders on the V6
under light load conditions — operating the engines as a V - 4 — and seamlessly reactivates the cylinders when the driver demands greater power.
The crossover's fuel - saving cylinder - deactivation technology (which can shut down two or even three cylinders while cruising
under light load conditions) is seamless in action, and we never heard or felt it during our time with the RDX.
It's
the light load conditions that should be optimized for emissions and fuel consumption IMO.
It deactivates four of the cylinders on the V - 8 engines and two cylinders on the V - 6 under
light load conditions — operating the engines as a V - 4 — and seamlessly reactivates the cylinders when the driver demands greater power.
A «cylinder on demand» (COD) version that runs on just two cylinders under
light load conditions is both more powerful (103kW / 250Nm — the latter between a narrower 1500 - 3500rpm range), quicker (0 - 100 km / h in 8.4 seconds) and efficient (4.7 L / 100 km).
