The HR-V seems to be surprisingly light -- is just 32KG heavier than the Civic 1.8E, and 4KG heavier than the Altis 1.6V and 1.6G CVT...
The HRV is based on the Jazz platform which is around 200kg lighter than the Civic 1.8L. The raised suspension together with the other stuff thus bring the weight of the HRV to just above the Civic 1.8L.
