Mercury's full-size sedan combines rear-wheel power and the latest equipment for safety and comfort. For 2003, the structure has been upgraded with a stiff frame featuring boxed front sections forged from hydroformed steel. A fresh face applies with bold headlamp clusters, a bright grille and restyled low fascia. Seats in the cabin were redesigned for comfort and fashion more legroom for the back seat. Mercury divides Grand Marquis into the two essential trim series of GS and LS, then adds packaged equipment in further segments, such as the Convenience array for GS or LS in Premium, Ultimate and five-seat LSE. Beneath the extended hood, a single-cam 4.6-liter V8 achieves 224 hp in all issues save LSE, where twin exhausts increase power to 239 hp.
