A revised WK series was launched in May 2003, with a facelift. The curvaceous front and rear end styling of the WH was abandoned in favour of angular lines, starting with the headlights borrowed from the VY Calais. From the rear, the redesigned taillights were now separated by sheet metal, rather than being joined with a horizontal strip of plastic. The redesign had the after effect of lowering the WK's drag coefficient to 0.30. Other changes came in the form of revised bumpers, wheel trims, with the interior dashboard and centre console receiving a major overhaul. Powertrains carried over from the previous model, but the "Generation III" V8 engine was now rated at for the Statesman and for the Caprice. Other engineering changes were made to the structural integrity of the car.
