For 1985, an intercooled version of the 2-litre turbo engine (B200ET) was introduced for markets such as Italy, where larger engines were heavily taxed. This unit produces at 5500 rpm, ten horsepower more than the preceding non-intercooled B19ET variant, enough for a claimed top speed. Model year 1986 marked the worldwide introduction of the station wagon; other differences were limited to a new font for the "740" badging and new hubcap designs. First shown at the 1988 Geneva Motor Show with tentative specifications but only going on sale with the introduction of the 1989 model year cars, a 16-valve version of the larger B230 engine was introduced (B234). This model has nearly as much peak power as the turbo version and was Volvo's first multi-valve engine.
