Like its predecessor, the 968 was offered in coupé and convertible bodystyles.<ref>{{cite web |title=Model Versions |url=https://www.porsche.com/usa/accessoriesandservices/classic/models/968/ |publisher=Porsche |access-date=25 June 2024}}</ref> The 968 was powered by an updated version of the 944's [[straight-four engine]], now displacing 3.0&nbsp;L with a 104&nbsp;mm bore and an 88&nbsp;mm stroke and rated at {{convert|240|PS|kW hp|0|abbr=on}} at 6,200 rpm and {{convert|305|Nm|lbft|0|abbr=on}} of torque at 4,100 rpm. Modifications to the engine include a higher 11.0:1 compression ratio, lighter crankshaft, crankcase and pistons along with revised intake valves and intake manifold. Changes to the 968's powertrain also included the addition of Porsche's then-new [[VarioCam]] [[variable valve timing]] system, newly optimized induction and [[exhaust system]]s, a dual-mass flywheel, and updated engine management electronics. The 968's engine was the fourth-largest four-cylinder engine ever offered in a production car at that time. A new 6-speed manual transmission replaced the 944's old 5-speed, and Porsche's dual-mode 4-speed [[Tiptronic]] [[automatic transmission|automatic]] became an available option. Both the VarioCam timing system and Tiptronic transmission were very recent developments for Porsche. The Tiptronic transmission had debuted for the first time only 3 years prior to the debut of the 968, on the 1989 [[Porsche 964|Type 964 911]]. The VarioCam timing system was first introduced on the 968 and would later become a feature of the Type 993 air-cooled six-cylinder engine.<ref name="AMS (12_91_S62)">''Auto, Motor und Sport'' Magazine, Issue Nr. 12 of 1991, p. 62.</ref><ref name="AMS (16_91_S25)">''Auto, Motor und Sport'' Magazine, Issue Nr. 16 of 1991, p. 25.</ref><ref name = "Jürgen Barth (S174)">[[#JBGB|Barth and Büsing]], p. 174.</ref>

Much of the 968's chassis was carried over from the 944&nbsp;S2, which in itself shared many components with the 944 Turbo (internally numbered ''951'') due to lack of development funds at the time. Borrowed components include the [[Brembo]]-sourced four-piston brake calipers on all four wheels with ventilated brake rotors, ABS,  aluminium semi-trailing arms and aluminum front A-arms, used in a [[Macpherson strut]] arrangement. The steel unibody structure was also very similar to that of the previous models. Porsche maintained that 80% of the car was new.<ref>{{cite web|url=https://www.pistonheads.com/news/ph-feed-porsche/porsche-968-ph-buying-guide/34290|title=Porsche 968: PH Buying Guide|date=31 May 2016|work=PistonHeads|access-date=4 May 2019}}</ref><ref>{{cite web|url=https://www.autoblog.com/2015/06/30/porsche-968-motorweek-retro-review-video/|title=The dream of the '90s is alive in Porsche 968 retro review|date=30 June 2015|first=Jonathon|last=Ramsey|publisher=Autoblog|access-date=4 May 2019}}</ref><ref name = "Jürgen Barth (S169)">[[#JBGB|Barth and Büsing]], p. 169.</ref>

The 968 can attain a top speed of {{convert|252|kph|mph|0|abbr=on}} when equipped with the manual transmission and has a 0&ndash;{{convert|100|kph|mph|0|abbr=on}} acceleration time of 6.5 seconds.<ref name="MOT (15_91_S20)">''Mot'' Magazin, Issue Nr. 15 of 1991, p. 20.</ref>

For the 1993 model year, the 968 received minor changes which included a pollen filter to increase the cleanliness of the air being channeled through the air conditioner and the introduction of special packages. The seat package included heated driver and front passenger seats, the sound package included an additional amplifier in the coupé and two additional speakers installed at the rear in the convertible while the suspension package included larger 17-inch wheels and an improved braking system with cross-drilled brake discs.<ref name = "Jürgen Barth (S175)">[[#JBGB|Barth and Büsing]], p. 175.</ref>
