In 1984 the Saab ”B202”–engine was introduced, that pawed the way for the modern turbocharged 4-cylinderengine. Downsizing as we know now means that a smaller engine has the same power and torque characteristics as a bigger naturally aspirated one, but still with the lower fuel consumption and exhaust emissions from the smaller one.
The engines cylinder volume was 1.985cc and the new cylinder head had 4 valves per cylinder. The engine management system was a combination between the new Bosch LH-Jetronic and the Saab APC-system with knockregulation. This engine was introduced in the Saab 900 T16 Aero ( SPG on the US-market ) and later in the Saab 9000.
The maximum power was 160-185hp and the maximum torque was 255-273 Nm.
Thanks to it´s engine characteristics and special exhaust note, the Saab B202 today has a cult status among the enthusiasts.
