BMW introduced the 525tds for the 1992 model year. This new series of cars were variants of the E34 5 Series, and were powered by BMW's M51D25 engine. This intercooled 2.5L inline six turbodiesel engine produced 140hp, and sent its power to the rear wheels through manual or automatic transmission options. The 525tds was only available as a rear wheel drive sedan, and was built until 1996, although the model series continued life in the next generation E34 BMW 5 Series.
