For the 1987 model year, the 944 S (the S being the abbreviation of '''S'''uper) was introduced.<ref>{{Cite web |title=Everything you need to know about the Porsche 944 |url=https://www.porsche.com/ |access-date=2024-03-01 |website=www.porsche.com |language=en}}</ref> The 944 S featured a high performance naturally aspirated, dual-overhead-cam 16-valve {{convert|190|PS|kW hp|0|abbr=on}} version of the 2.5&nbsp;L engine (M44/40) featuring a self-adjusting timing belt tensioner. This marked the first use of four-valves-per-cylinder [[cylinder head|head]]s and DOHC in the 944, derived from the 928 S4 featuring a redesigned camshaft drive, a magnesium intake tract/passages, magnesium valve cover, larger capacity oil sump, and revised exhaust system. The alternator capacity was 115 amps. The wheel bearings were also strengthened and the brake servo action was made more powerful. Floating 944 calipers were standard, but the rear wheel brake circuit pressure regulator from the 944 turbo was used. Small '16 Ventiler' script badges were added on the sides in front of the body protection mouldings. Performance figures included 0-{{convert|100|km/h|mph|abbr=on}} being achieved in 6.5 seconds (Best) and a {{convert|232|km/h|mph|abbr=on}} top speed due to a {{cvt|1296|kg|lb|0|abbr=on}} curb weight. It also featured an improved programmed Bosch Digital Motronic 2.1 Computer/DME with dual knock sensors for improved fuel performance for the higher 10.9:1 compression ratio cylinder head. Like the 944 Turbo, the 944 S received progressive springs for improved handling, larger front and rear anti-roll bars, revised transmission and gearing to better suit the 2.5&nbsp;L DOHC engine's higher 6,800 rpm rev limit. Dual air bags, limited-slip differential, and an anti-lock braking system were optional on the 944 S.

A Club Sport touring package (M637) was available as was the lightweight 16-inch CS/Sport Fuchs 16x7 and 16x9 forged alloy wheels. This version was raced in Canada, Europe and in the IMSA Firehawk Cup Series held in the U.S. Production was only during 1987 and 1988. It was superseded in 1989 by the 'S2' version. The 1987 944 S' power-to-weight ratio was such that it was able to accelerate from 0 to 100&nbsp;km/h in 6.5 seconds thus matching the acceleration of its newer larger displacement 3.0&nbsp;L 944&nbsp;S2 sibling.
