Taken from the Acura Legend Wiki:
Honda introduced the model in 1985 in Japan to be their premier luxury model and in 1986 North America as the range-topping model in its then-new Acura lineup. The first generation Legend is notable for many technical innovations. The coupe was the first to be engineered using CAD (computer aided design). Sedan models came to market first, powered by a 151 hp (113 kW) 2.5 L C25A V6 with coupes appearing for 1987 powered by a new 161 hp (120 kW) 2.7 L C27A engine. Sedans received the new engine for 1988. Production of the first generation models ended in 1990 as a second generation version became available.
The Legend was indeed an impressive car receiving accolades from all sides, winning Car and Driver's Ten Best three years in a row and Motor Trend's "Import Car of the Year" for 1987. Legends were regarded for their impeccable fit and finish, incredible reliability, and good performance. Manual-equipped models could sprint to 60 mph (97 km/h) in under 8 seconds and reach a top speed of 135 mph (217 km/h). Sedan models had a coefficient of drag of .32, while coupes were only .30.
Technical highlights were numerous, featuring a 24-valve V6 engine, variable length intake manifold, double-wishbone suspension, 4-wheel disc brakes, air bag and an information system that could monitor maintenance intervals, fluid levels, and fuel economy.
In 1989, the sedan received some minor tweaks with new one-piece front headlamps, a new front bumper, a revised trunk lid, new tail lights, and new alloy wheels. Inside, a revised dash and seat cloth patterns is also noticeable. The high end LS now featured a trip computer in the center stack.
In 1990, the Legend LS coupe was revamped with a woodgrain interior, clear/red taillights, and a new body-colored grille. The sedans also received the woodgrain interior for the LS model.
