saab b204l

The Saab H engine is a redesign of the Saab B engine, which in turn was based on the Triumph Slant-4 engine.
Despite the name it is not an H engine or horizontally opposed engine, but a slanted inline-4. The H engine was introduced in 1981 in the Saab 900 and was also used in the Saab 99 from 1982 onwards. H stood for high compression; higher compression was part of the update from B to H engine. It continued in use in the 900/9-3, 9000, and 9-5. The 2003 GM Epsilon-based 9-3 switched to the GM Ecotec engine, leaving the 9-5 as the sole user of the H engine. The H family of engine was used in the first-generation 9-5 until it was discontinued in 2010. The tooling and know-how was sold to BAIC. The latter B2X4 and B2X5 engines have in practice nothing in common with the early B engines except cylinder spacing....
