1985โ†’1989 Hartge H35-24

The H35-24โ€™s were the top model in Hartgeโ€™s 1980โ€™s E30 H35 line up and was released in October of 1985. Conversions began on the BMW E30 range in 1981 initially as a tuning house until in 1985 when Hartge were granted manufacturer status by the German Motor Vehicle Authority (KBA). From then on all Hartge cars received a Hartge motorsport VIN plate that was attached to the vehicle in place of the original BMW one.

The H35 (from 1981) and H35-24 (from 1985) could have different motor configurations depending on that year they were produced and the market they were intended for, all were based on the BMW M30 โ€œbig sixโ€ Block. Initially the H35 using the 3 46 EB @ 199 kw (M30B34) from the 5 series BMW where the H35-24 used the 3 56 ED @ 210 kw (M88/3) 24 valve motor modified from the BMW M1 for BMWs use in the M635csi. From 1986 Hartgeโ€™s attention moved to the new E30 M3 this led to the development of the last of the H35โ€™s the H35-24s also initially with the M88/3.

Later H35 conversions used the next generation of BMW motors from the 5 and 6 series. From 1988 the H35 used the M30B35 and the H35-24 and 24s using the S38B35. Initial conversions where done on the BMW E30 323i until 1986 when the 325i was used as the donor into the early 1990โ€™s, bar the โ€œsโ€ that used the M3.

The H35-24 time in the limelight was relatively short as the H35-24s M3 conversions soon over shadowed it, therefore are a rare vehicle, with only six originally produced by the factory in 1985 with the M88/3.

Production numbers are difficult to determine as conversions/builds were only done on request and also carried out by authorised Hartge agents outside of Germany. Source: Hartge Brochures and Technical documentation (KBA & TUV submission 12/84)
