The y26se is a General Motors Europe internal combustion engine. It is a 2.6 litre V6 petrol engine, it has 24 valves, produces 170 PS (168 bhp) in standard form, and generates a torque turning force of 227 newton metres (167 ft·lbf).

This engine is the successor to the x25xe v6 which was dropped due to emmission restrictions, general motors revised the design by lowering the compression ratio but raising the displacement from 2,498cc to 2,597cc by increasing the bore size from 81.6mm to 83.2mm.

It retains the unusual 54 degree cylinder bank angle, as opposed to the more conventional 60 degree setup used on many V6 units for compactness.

The engine management system was changed which utilised quad lambda sensor control, coil per plug ignition system and drive by wire throttles. As a result of these changes the EGR and secondary air injection system were removed.
