Hyundai Massages Lambda V-6 for '09 Genesis Coupe

October 9, 2008
For sporting duty in its upcoming '09 Genesis Coupe, Hyundai has made internal and external changes to its 3.8-liter Lambda V-6, reports World Car Fans. Dubbed the RS edition, power output is barely changed, but packaging efficiency is increased to fit under the Coupe's lower hood, and mechanical changes should further improve durability and drivability before the engine is released into the sweaty palms of what could be Hyundai's sportiest buyer demographic to date.

While the RS Lambda V-6 adds only 4 horsepower and 3 pound-feet to the mix (for a total of 310 hp, 266 pound-feet), more aggressive lobes on the engine's continuously variable exhaust and intake camshafts should bolster responsiveness. For durability under high-stress operating conditions, the aluminum block is stiffened and piston-cooling oil jets (a strategy typically employed in turbocharged engines) are fitted below the pistons.

To improve the engine's fit under the Genesis Coupe's lower hood, a redesign of the intake and exhaust systems resulted in an engine height lower by 5cm. At the same time, airflow into and out of the engine was improved, yielding better high-rpm performance and a more aggressive exhaust note.--Colin Mathews
