Stillborn: 1989 BMW M5 convertible

These days BMW's M division is pretty busy, cranking out all manner of sport-tuned models in every form. You can get an M3 as a coupe, convertible or sedan, the M5 in sedan or wagon form, and the M6 as either a coupe or a convertible, in addition to M versions of the Z4. But back in the late '80s, the selection of M cars was much more limited. Not that the engineers in the sporting division weren't trying, though. Case in point is this M5 cabrio prototype that almost made it into production, but was canceled at the last minute.
Starting with an E34-generation M5 sedan, engineers in Munich chopped off the roof, strengthened the chassis and replaced the four doors with two longer ones. (If you think the idea is entirely absurd, just look at the Audi A4 cabrio and its quattro GmbH-tuned versions.) The resulting M5 convertible prototype was actually scheduled to debut at the 1989 Geneva Motor Show and even priced at £50k for the British market, but fearing that its addition to the BMW line-up would create demand for a conventional 5-series convertible and subsequently harm sales of the existing 3-series cabrio, BMW executives decided to kill the project. Only one prototype of the M5 convertible was made bearing ZS license plates from the BMW Individual program, as you can see in the gallery below.

Every time I see clean, older BMW's, my hate for Chris Bangle is renewed.

It doesn't look that bad, but why would they use the E34 5er, when they had the E24 6er coupe to work with.

The e24 was on the way out (discontinued in 89, the year this would have debuted) whereas the e34 had just dropped in 87. Put the newest chassis not the one that's been kicking around since 76. Also, it looks a lot better with the even hood/trunk proportions, the e24 would have been all hood and no trunk (which, don't get me wrong, look amazing in coupe format but probably would have looked funny in cabrio).

I could see it harm 3 series sales at the time. Also would have harm 6 series coup sales. Nice effort though.

So BMW was afraid to add another model because it might cannibalize sales of existing models? My, how things have changed! They went from just 3, 5 and 7 series to what, like 100 models now?
Wow, that M5 'vert looks great. Would've bought one (well not in '89 because I was in high school, but later.)

I'm thinkin' maybe they killed it because it looks almost exactly like the 3 series convertible of that vintage. I have one, and from these photos, it's almost like lookin' in my garage!

It does look damn good doesn't it. This car just looks awesome, I couldn't imagine seeing this sleek machine going down the road in 1989.

Looks a lot better than the current 6-series. I used to have an '87 325i... God I loved that car!

It's very nice, no doubt about it but I prefer the E30 M3 convertible. (Probably because I'm freakin' biased.)

They were worried about sales being cannibalized... by a more expensive model. Why would customers opting to buy a higher-priced model be considered a problem?

I love it, it's amazing.
I'm sure it would run with a current or last gen 3 series cabrio more then then any current M car though.
In short, I love it and I want it.

this looks awesome... but imagine how the modern (e60) equivalent would look -- *barf*

It looks really good as a coupe. Must be a blast to drive.

BMW should have just continued with the 6-series if they were thinking about selling a M5 convertible.
speaking of which, when will we get a 6-series with the twin-turbo in-line six cylinder? that would be a great addition to the U.S. market
