The Mercedes-Benz 190D, 190Db, and 190SL were a series of compact executive cars produced by Mercedes-Benz from 1982 to 1993. They represented a significant departure from the brand's traditional large sedans, offering a more affordable and fuel-efficient option without compromising on the expected Mercedes-Benz quality and engineering. The 190D was powered by a 2.0-liter naturally aspirated diesel engine, offering impressive fuel economy but a relatively slow acceleration. The 190Db, an updated version of the 190D, featured a turbocharged diesel engine, significantly boosting power and performance while maintaining remarkably good fuel efficiency. The 190SL, a two-door coupé version, was powered by a petrol engine, offering a more spirited driving experience. All three models shared a common platform with a longitudinally mounted engine and rear-wheel drive. They were renowned for their robust construction, advanced suspension design, and sophisticated interior. Notable features included a double-wishbone front suspension and a multi-link rear suspension, offering comfortable ride quality and excellent handling. The interior was known for its elegant design and high-quality materials. The 190 series was also a pioneer in safety innovations, introducing features like anti-lock brakes (ABS), electronic stability program (ESP), and driver airbags. Despite their compact size, the 190s offered ample passenger space and trunk capacity. While the 190D and 190Db found favor among frugal buyers, the 190SL gained a reputation as a stylish and dependable sports coupe. The 190 series was a success for Mercedes-Benz, cementing the brand’s reputation for quality and innovation in the compact executive car segment.
