Both vehicles were initially powered by the 3. 0 L Nissan VG30E V6 engine until 1998, when the Quest received the 3. 3 L version of the same engine and a few minor updates, including a driver side sliding door, and grille and rear redesigns. The Quest was completely redesigned for 2004, while the Villager was discontinued and replaced with the Freestar-based Mercury Monterey. The third generation model was built on the FF-L platform, which it shares with the Altima, Maxima, Teana, and Murano. It also shares the 3. 5 L VQ engine with those cars. The fourth generation model is built on the same platform as the 2011 Nissan Elgrand.
