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>

From October 1992 through 1995, Porsche offered a lighter-weight "Club Sport" version of the 968 designed for enthusiasts seeking increased track performance. Much of the 968's luxury-oriented equipment was removed or taken off the options list; less sound deadening material was used, power windows were replaced with crank-driven units, upgraded stereo systems, A/C and sunroof were still optional as on the standard coupé and Convertible models. In addition, Porsche installed manually adjustable lightweight [[Recaro]] racing seats rather than the standard power-operated leather buckets (also manufactured by Recaro), a revised suspension system optimised and lowered by 20&nbsp;mm for possible track use, 17-inch wheels (also slightly wider to accommodate wider tyres) rather than the 16-inch as found on the coupé and wider tyres, 225 front and 255 rear rather than 205 and 225 respectively. The four-spoke airbag steering wheel was replaced with a thicker-rimmed three-spoke sports steering wheel with no airbag, heated washer jets were replaced with non heated, vanity covers in the engine bay were deleted, as was the rear wiper. The Club Sport has no rear seats, unlike the 2+2 Coupé.<ref>{{cite web|url=https://www.classicdriver.com/en/article/cars/modern-classics-porsche-968-cs|title=Modern Classics: Porsche 968 CS|date=10 November 2014|work=Classic Driver|access-date=4 May 2019}}</ref><ref>{{cite web|url=https://www.thedrive.com/flat-six-society/6280/factory-lightweight-porsche-968-clubsport-is-the-one-you-really-want|title=Factory Lightweight Porsche 968 Clubsport Is The One You Really Want|date=1 December 2016|first=Bradley|last=Brownell|publisher=The Drive|access-date=4 May 2019}}</ref>

Model year 1993 Club Sport models were only available in Grand Prix White, black, Speed yellow, Guards red or Maritime blue exterior colours. Seat backs were colour-coded to the body. "Club Sport" decals were applied to UK market cars in either black, red or white but there was a 'delete' option.

For model year 1994, Riviera blue replaced Maritime Blue and a number of other colours and option packs were available including the option to add comfort rear seats with an electric boot release.

All Club Sports had black interiors with simpler door cards similar to the 944. Due to the reduction in the number of electrical items the wiring loom was reduced in complexity which saved weight and also the battery was replaced with a smaller one, again reducing weight. With the no frills approach meaning less weight, as well as the optimising of the suspension, Porsche could focus media attention on the Club Sport variants fast road and track abilities. This helped to slightly bolster the flagging sales figures in the mid-1990s. The Club Sport variant achieved a 'Performance Car Of The Year' award in 1993 from Performance Car magazine in the UK. Club Sport models were only officially available in the UK, Europe, Japan & Australia, although "grey market" cars found their way elsewhere. The declared weight of the 968&nbsp;CS is {{Convert|1320|kg|lb|0|abbr=on}}, ~{{Convert|100|kg|lb|0|abbr=on}} lighter than the regular 968. Acceleration from a standstill to {{convert|97|km/h|mph|abbr=on}} takes 5.6 seconds and top speed is {{convert|260|km/h|mph|0|abbr=on}}.<ref>{{cite web|url=https://www.hemmings.com/blog/article/1992-1995-porsche-968/|title=1992-1995 Porsche 968|date=April 2010|first=David|last=LaChance|publisher=Hemmings Sports and Exotic|access-date=4 May 2019}}</ref>

Out of a total of 1538 cars produced by Porsche, 1232 were registered as 968 CS. The remaining 306 cars were registered as "968 Sport" (see below).

A UK-only version called "968 Sport", was offered in 1994 and 1995, and was essentially a Club Sport model (it uses CS chassis numbers) with various model year 1994 option packs to create the P35 "CS UK Luxury Pack". This added an alarm, power windows / mirrors, electric release boot, central locking, sunroof and cloth ''comfort'' front and rear seats (the same front seats were a non cost option on the CS). With the added electrics the larger wiring loom was used. At £32,995, the 968 Sport was priced £4,500 lower than the standard 968, but had most of the latter's desirable "luxuries" and consequently outsold it by a large margin (306 of the 968 Sport models compared to 40 standard 968 coupés).<ref name=Morgan>[[#PM98|Morgan (1998)]]</ref><ref>{{cite web|url=https://classicsworld.co.uk/news/road-test-1993-porsche-968-sport/|title=Road Test – 1993 Porsche 968 Sport|date=28 February 2018|work=Classics World|access-date=4 May 2019}}</ref>

=== 968 Turbo S ===
In 1993, Porsche Motorsports at Weissach briefly produced a [[Turbocharger|turbocharged]] 968 Turbo S, a fairly odd naming choice for Porsche which usually reserves the added "S" moniker for models that have been tuned for more power over a "lesser" counterpart, such as with the 911 Turbo. The 968 Turbo S shared the same body and interior as the Club Sport and visually can be identified by the NACA bonnet hood scoops, adjustable rear wing, three-piece speedline wheels and deeper front spoiler. The car had the suspension lowered by {{cvt|0.7|in|mm|1|abbr=on|order=flip}} and was {{cvt|45|lb|kg|0|abbr=on|order=flip}} lighter than the standard 968.<ref>{{cite web|url=https://carbuzz.com/news/rare-porsche-968-turbo-s-one-of-only-14-in-the-world|title=Rare Porsche 968 Turbo S One Of Only 14 In The World|date=15 March 2019|first=Martin|last=Bigg|publisher=Carbuzz|access-date=4 May 2019}}</ref> The 968 Turbo S was powered by a 3.0&nbsp;L engine with an 8-valve SOHC cylinder head (from the 944 Turbo S) and 944S2 style engine block. Tests conducted in 1993 returned a 0 to {{convert|97|km/h|mph|0|abbr=on}} time of 4.7 seconds and a top speed of {{convert|282|km/h|mph|abbr=on}}. The engine generated {{convert|309|PS|kW hp|abbr=on}} at 5,600 rpm with a maximum torque of {{convert|500|Nm|lb.ft|0|abbr=on}} at 3,000 rpm.<ref name = "Christophorus (2_93)"> '' Christophorus '' Porsche Magazine, Issue No. 2 of 1993.</ref><ref name = "Jürgen Barth (S182)">[[#JBGB|Barth and Büsing]], p. 182. </ref><ref name = "Jürgen Barth (S179)">[[#JBGB|Barth and Büsing]], p. 179. </ref> Only 14 were produced in total and only for sale in mainland Europe.
