For 2000, Nissan's flagship Maxima sedan enters its fifth-generation on the market. A sporty outer appearance and a larger, quieter interior are recognized on the 2000 Maxima. Nissan's 2000 model year changes appear destined to attract more of the youthful automotive crowds. The Altima sedan is treated to significant design and technical refresh to make the vehicle more comfortable and quiet. All-new for 2000, the Nissan Xterra is a step back to traditional off-road sport utility vehicle roots with available four-wheel drive. Nissan's compact entrant, the Sentra, has gained a full restyling for 2000. Built on a global platform, the new Nissan Sentra four-door sedan is 6.5 inches longer and 1.1 inches taller than the 1999 model. Midway through the 1999 model year, the Nissan Pathfinder received a host of refinements. Front and rear styling, engine power as well as the interior feature improvements on the sport utility vehicle introduced as a 1999.5 model. Joining the regular and King Cab body styles of the Nissan Frontier, 2000 marks the debut of a four-door Crew Cab.
