The Porsche 944, a mid-engined sports car produced from 1982 to 1991, established itself as a highly capable and refined machine within the marque's lineup. The 944 S, introduced in 1987, built upon the foundations of its predecessor with a number of significant enhancements. Notably, it received a larger 2.7-liter engine, generating 162 horsepower, a power increase that translated into a more spirited driving experience. Additionally, the 944 S featured a revised suspension for improved handling, larger brakes for enhanced stopping power, and a host of aesthetic refinements, including a distinct rear spoiler and a more aggressive front fascia. This combination of improved performance, handling, and styling cemented the 944 S as a compelling option for driving enthusiasts.

The 944 S evolved further with the arrival of the 944 S2 in 1989. This iteration boasted a larger 3.0-liter engine with 208 horsepower, marking a substantial power upgrade. The S2 also benefited from a revised transmission with shorter gear ratios, allowing for quicker acceleration and more responsive performance. Further enhancing the S2's dynamic capabilities, Porsche implemented a Torsen limited-slip differential, promoting excellent traction and handling, especially in demanding conditions. Visually, the S2 could be identified by its wider rear wheel arches, accommodating the larger tires required for its increased power output. The 944 Turbo, introduced in 1985, offered an even more potent performance package. With a turbocharged version of the 2.5-liter engine, producing 217 horsepower, the 944 Turbo provided exhilarating acceleration and a thrilling driving experience. The Turbo was further distinguished by its unique aerodynamic enhancements, including a larger rear spoiler and a distinctive front air dam.
