1985→1989 Hartge H35-24

The H35-24’s were the top model in Hartge’s 1980’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 “big six” 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 Hartge’s attention moved to the new E30 M3 this led to the development of the last of the H35’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 1990’s, bar the “s” 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)
