Though definitely not as unique or attention-grabbing as the 1989 E34 M5 soft-top Convertible that we showed you in an earlier post here on Carscoop, the one-off E39 M5 Touring prototype that was also revealed by BMW at a special event in Germany commemorating the 25 years of the M5 and photographed by the folks over at 'Bimmertoday', is certainly worth a second look .The E39-based M5 Touring, which for various reasons never made it pass the prototype phase, was powered by the same naturally-aspirated 4.9-liter V8 engine with 400 ponnies as its sedan doppelganger.
The only other M5 Touring to be series produced by BMW other than today's V10-powered model (E60 sedan / E61 Touring), was the E34 M5 that was fitted with an inline-six cylinder engine.
