The 6G73 displaces 2,497 cc. It is a 24-valve SOHC design with two valves running off a single cam lobe, with a smaller bore than the 3.0 liter version of the same block. Bore and stroke are 83.5 mm × 76 mm (3.29 in × 2.99 in); it is a 60-degree V6 and weighs around 155 kg (340 lb). The engine has low-profile cast aluminum heads which help it to fit into compact engine bays, while pent-roof combustion chambers increase efficiency and make room for four valves per cylinder, arranged in a cross-flow pattern with a "tumble" intake port for both strong breathing and low emissions. Spark plugs are centered in the combustion chambers. The intake valves are 33 mm (1.30 in) in diameter while exhaust valves are 29 mm (1.14 in). A toothed timing belt is used. The output of 6G73 is 161 hp (122 kW; 163 PS) at 5,900 rpm with 221 Nm (163 lb-ft) of torque at 4,350 rpm.
