The invention provides a 800MPa grade hot-rolled dual phase steel plate with excellent performance and a manufacturing method thereof. The components of the steel plate include, by weight percentage,0.04-0.08% of C, 0-0.10% of Si, 1.6-2.0% of Mn, 0.20-0.40% of Als, 0.50-0.80% of Mo, 0.02-0.05% of Nb, 0.02-0.05% of Ti, P being less than 0.02%, and S being less than 0.005%, with the balance being Fe and inevitable impurities; and the manufacturing method includes smelting, continuous casting, heating, rolling and cooling. The intensity of the produced dual phase steel plate can reach more than800 MPa, and the ferrite content can reach 85-95%; and the steel plate has good intensity and elongation cooperation and excellent forming performance.
