The invention relates to hybrid vehicle engine start. The vehicle includes: an engine having a crankshaft; a transmission having an input; and an electric machine mechanically coupled to the transmission input. The vehicle further includes a clutch configured to mechanically couple the electric machine and the engine crankshaft, and at least one controller. The at least one controller, in response to an engine start condition and subsequent partial engagement of the clutch, outputs a torque command for the electric machine to increase the speed of the crankshaft to a speed of the electric machine before commanding fuel injection of the engine. The torque command is based on driver demanded torque and a change in speed of the crankshaft caused by changes in pressure to the clutch.
