The second-generation Prelude was released in Japan on November 25, 1982 and worldwide in 1983. Riding on an all-new platform, the Prelude was initially available with an A18A or ET-2, 1.8 L 12-valve twin carburetor engine, producing 110 hp (77 kW), with fuel injection introduced in the "Si" models in 1985. In Japan, Asia and Europe, it was available with a 2-liter DOHC 16-valve PGM-FI engine (JDM = BA1, EU = BA2) although this engine was not released in Europe until 1986. The JDM B20A produced 160 PS (118 kW) at 6,300 rpm, while the European B20A1 produced only 137 hp (102 kW).
This was the first generation of Prelude to have pop-up headlights, which allowed for a more aerodynamic front clip, reducing drag. Opening the headlights, however, especially at higher speeds, produced significantly more drag. The 1983 model is identifiable by its standard painted steel wheels with bright trim rings (although alloy rims were optional). The 1984-87 base models had Civic-style full wheel covers. In Canada, a "Special Edition" trim was created, which is essentially the same as the USA 2.0Si "sport injected" model.
In Japan, the Prelude was one of the key models sold at Japanese Honda dealership sales channels, called Honda Verno, which offered performance-oriented products. All Honda Verno products, like the Vigor, initially shared the concealed headlights introduced with this generation Prelude that would help identify "sports" products from Honda in Japan however, the approach was short-lived.
