The 320is has a 2.0 S14 engine (1990cc), a stroked version ( 93,4 x 72,6 ) of the E30 M3's 2.3 S14 four cylinder, producing 192 bhp or 141 kW at 6900 rpm. It also shares the dogleg Gertag gearbox and taller ratio 25% limited slip diff from the M3.
Four door models have standard exterior but two door models were fitted with the M-Technic II body kit, consisting of a front spoiler, side skirts and a rear spoiler. Two door models had Shadowline (dechroming) and the bumpers, mirrors and spoilers were body coloured.
The interior is fitted with front sport seats, M-Technic steering wheel, electric windows and the dials are the same as in the E30 M3 but without the red needles. An oil temperature gauge is integrated in the rev counter.
