redesigned, featuring fully coloured rounded taillamps. Special bulbs were used in the taillamps which either illuminated a small area in amber colour when the turn signals were activated or in white when the car was reversing. PORSCHE badging was fitted between the taillights just below the model type number. The rear apron was integrated into the smoothened rear bumper. While the exterior of the car was rounded and smoothed, the interior was largely unchanged and mostly shared with the preceding 944 S2 with the exception of switches and control knobs. The 968 also featured numerous small equipment and detail upgrades from the 944, including a Fuba roof-mounted antenna, updated single lens tail lamps, "Cup" style 16-inch alloy wheels, a wider selection of interior and exterior colours, a slightly updated "B" pillar and rear quarter window to accommodate adhesive installation to replace the older rubber gasket installation. Models 968 Like its predecessor, the 968 was offered in coupé and convertible bodystyles. The 968 was powered by an updated version of the 944's Inline-four engine, now displacing 3.0 L with a 104 mm bore and an 88 mm stroke and rated at at 6,200 rpm and 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 systems, 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 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 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. Much of the 968's chassis was carried over from the 944 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
