While the rear seats aren't captain seats, they can individually recline and the center seat features a hidden table. Announced in September 1999, the Avancier was available with a 2.3-liter 4-cylinder engine, or a 3-liter V6. Both were only available with automatic gearboxes; at the time of launch Honda said the 3-liter is the first Honda with a five-speed automatic gearbox. An Intelligent Highway Cruise Control system, which uses a radar to determine and maintain distance with the car in front, is optional for the V6. All-wheel drive is available for the 2.3-liter. It appears that as of late 2003, production of the Avancier has ceased due to poor sales. The Avancier was very reliable. The Avancier is built on the largest of the global Accord architectures, developed for the American and Asian-Pacific markets except Japan, which prefers a compact version. Its wheelbase is 50 mm (2 in) longer than the U.S. Accord's, at 2765 mm (109 in), while the overall length of 4700 mm (185 in) is shorter. Its overall width is 1790 mm (70 in), and it is taller than the sedan at 1500 mm (59 in). The car features four conventional doors and a rear hatch, which wraps over the roof with a glass "top light." The Avancier is fitted with standard high-intensity-discharge low-beam headlamps. The body style and configuration do not duplicate another Japan-exclusive Accord variant, the station wagon. The car's height is exploited to provide unique interior ambience and convenience—sort of a cross between a luxury sedan and a compact minivan. The low central tunnel and a dashboard-mounted transmission selector lever allow walk-through between the front seats and between the front and rear compartments. Upper-model rear seats feature a fore-aft slide range of 70 mm (2.8 in) and seatback recline. With the seat at the rear-most position, leg room is superior to that of the larger Legend/Acura RL sedan. Luggage space under a hard shelf has a 350-L (12.4 ft3) volume; however, it can been increased by folding the 60/40-split rear seatbacks forward and level with the trunk floor.
