Page "Porsche 968" Paragraph 2

The 968 was powered by an updated version of the 944's straight-4 engine, now displacing 3. 0 L with 104 mm bore, 88 mm stroke and producing 240 PS ( 236 hp / 177 kW ).

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 among other more minor revisions.

The 968's engine was the second-largest 4-cylinder ever offered in a production car up to that time.

A new 6-speed manual transmission replaced the 944's old 5-speed, and Porsche's dual-mode 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 ever 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.
