The HR14DD engine in the new Serena e-POWER has a longer stroke and larger displacement compared to the current model HR12DE, resulting in 16% increase in power, and the high output of the motor has achieved acceleration and ease of driving.
The fuel-consumption is also 1.3 km/L better than the previous model thanks to direct injection, etc. Furthermore, the adoption of a primary balancer shaft and flexible plate reduces engine vibration and improves quietness.
