I'm a bit of an M5 freak so here's my take. The F90 and F10 have their own special editions but there's nothing much interesting going on there. Instead, the E34 had the most special/limited editions of any M5 generation.
First, is the
Winkelhock Edition. It was named after one of BMW's factory racing driver, Joachim Winkelhock who won the Nurburgring 24 Hours with a BMW M3 in 1990 and 1991. BMW approached him and asked him to create a special version of the E34 M5. As a result, it's a stripped out version but with Recaro seats, wider rear tires, and red seatbelts. Only
51 examples were made.
Second, is the
Cecotto Edition. Johnny Cecotto was an F1 driver and same affair with Winkelhock, he went on to create one special edition E34 M5. But instead of stripping out stuff from the car, he added more things like heated seats, wood trim, a power sunroof, and automatic climate control. The car was only available in two colours, Lagoon Green or Mauritius Blue, and had the option of interiors between Silvergray/Light Silvergray and Parchment/Light Parchment. Only
22 examples were made.
Third, is the
Naghi Motors Edition. Naghi Motors is an Arabian importer of BMW and they asked BMW to build them a limited edition E34 M5 for their country. As a result, it had a Euro-spec 3.6-liter M5, with a catalytic converter deletion. Also include are factory M rear spoiler, Shadowline exterior trim, and Recaro SR front seats in leather-cloth with a bit of M stripe on the front bonnet. Only
15 examples were made.
Fourth, is the
Elektra Edition. The different thing this time is it's in touring form. Hooray! As I understand, the car was requested by the Italian BMW dealers to create a limited edition E34 touring based ordered not through BMW M, but through BMW Individual. It was available in either Sterling Silver with Marine Blue leather, or British Racing Green with Tobacco leather, and features a very special gear knob. Only
20 examples were made.
Finally, is the usual
20 Jahre Motorsport Edition. I mean the name kinda explains itself, is to celebrate BMW M's 20th anniversary. The car was fitted with a 3.8-litre inline-six producing 335 horsepower, only available in Mugello Red and featured M-Technic rear-view mirrors, and Alcantara trimming on the seats, door panels, steering wheel, shift lever, and park-brake lever. Only
20 examples were made.
So there you go. A long list of special/limited edition E34 M5
