The E39 BMW M5 Touring is firmly in the second category \u2014 a prototype so close to perfect, so achingly close to what BMW enthusiasts had always wanted, that its absence from showrooms still stings more than two decades later.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">Back in 2009, as part of the celebrations marking the 25th Anniversary of the BMW M5, we were among a select group of journalists invited to Munich for a very private look at M GmbH\u2019s history. The setting was a secret garage tucked away from the public eye, and inside it sat some of the most extraordinary and rarely-seen BMWs ever created \u2014 the kind of room that makes a car person go quiet. Alongside the <a href=\"https:\/\/www.bmwblog.com\/2022\/06\/11\/e60-m5-csl-top-secret\/\">M5 CSL<\/a> and the never-produced <a href=\"https:\/\/www.bmwblog.com\/2026\/02\/23\/bmw-e34-m5-convertible-confirmed-cancelled\/\">M5 Convertible<\/a> sat the E39 M5 Touring, parked there as if it were the most natural thing in the world.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">This was 2009 \u2014 before Instagram, before YouTube vlogs, before every significant moment got documented, shared, and dissected in real time. There were no live streams, no tweet threads, no viral reels from inside that garage. Just a handful of journalists, a few old school cameras, and a car that BMW had never officially photographed for public release. It felt genuinely secret in a way that\u2019s nearly impossible to replicate today.<\/p>\n<h3>One Of The Biggest Secrets In Garching<\/h3>\n<p><a href=\"https:\/\/www.bmwblog.com\/wp-content\/uploads\/BMW-M5-E39-Touring-07.JPG\"><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone size-medium wp-image-22959\" title=\"BMW-M5-E39-Touring-07\" src=\"https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/BMW-M5-E39-Touring-07-750x562.jpg\" alt=\"The rear end of the E39 BMW M5 Touring\" width=\"750\" height=\"562\" srcset=\"https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/BMW-M5-E39-Touring-07-750x562.jpg 750w, https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/BMW-M5-E39-Touring-07-1024x768.jpg 1024w, https:\/\/www.bmwblog.com\/wp-content\/uploads\/BMW-M5-E39-Touring-07.JPG 1600w\" sizes=\"(max-width: 750px) 100vw, 750px\"\/><\/a><\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">And what a car to keep secret. Contemporary reports from the event indicated the E39 M5 Touring carried the sedan\u2019s 5.0-liter S62 V8, producing 400 horsepower and 500 Nm (369 lb-ft) of torque. In other words, the full M5 experience \u2014 just with room for a set of skis, a dog, a family\u2019s worth of luggage, or all three at once.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">To understand why this car is so mythologized, you have to understand what the <a href=\"https:\/\/www.bmwblog.com\/2025\/08\/06\/bmw-e39-5-series-buying-guide-2025\/\">E39 generation<\/a> means to BMW enthusiasts. The E39 M5 is widely regarded as one of the greatest performance sedans ever made \u2014 not just for its <a href=\"https:\/\/www.bmwblog.com\/2025\/04\/15\/bmw-s62b50-engine-reliability-efficiency-tuning\/\">S62 engine<\/a>, but for the way it looked. Chris Bangle\u2019s divisive flame-surfacing era was still a few years away, and the E39 carried a timeless, understated elegance that BMW has been quietly trying to recapture ever since. Long hood, perfectly proportioned flanks, a greenhouse that sits just right \u2014 it ages in a way that almost no modern car does. People don\u2019t just like the E39; they love it with the kind of devotion usually reserved for things that can\u2019t be replaced.<\/p>\n<h3>What A Design This Was<\/h3>\n<p><a href=\"https:\/\/www.bmwblog.com\/wp-content\/uploads\/BMW-M5-E39-Touring-10.JPG\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-22965\" title=\"BMW-M5-E39-Touring-10\" src=\"https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/BMW-M5-E39-Touring-10-750x562.jpg\" alt=\"The interior of the E39 BMW M5 Touring\" width=\"750\" height=\"562\" srcset=\"https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/BMW-M5-E39-Touring-10-750x562.jpg 750w, https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/BMW-M5-E39-Touring-10-1024x768.jpg 1024w, https:\/\/www.bmwblog.com\/wp-content\/uploads\/BMW-M5-E39-Touring-10.JPG 1600w\" sizes=\"auto, (max-width: 750px) 100vw, 750px\"\/><\/a><\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">Now imagine that body stretched into a Touring. The long roofline flowing back, the estate proportions adding visual drama without sacrificing an ounce of the sedan\u2019s grace. A practical, everyday car that could genuinely embarrass sports cars on a winding road. The M5 Touring would have been the ultimate sleeper \u2014 the station wagon that had nothing to prove and everything to offer.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">So why didn\u2019t it happen? Reporting at the time suggested BMW M shelved the project due to rear-axle and dynamics-related compromises \u2014 the longer Touring body reportedly creating challenges that couldn\u2019t be resolved without affecting the precise handling character M insists upon. Concerns about market size are said to have played a role as well, though neither reason has been formally confirmed by BMW in an official statement.<\/p>\n<p><a href=\"https:\/\/www.bmwblog.com\/wp-content\/uploads\/BMW-M5-E39-Touring-03.JPG\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-22950\" title=\"BMW-M5-E39-Touring-03\" src=\"https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/BMW-M5-E39-Touring-03-750x562.jpg\" alt=\"\" width=\"750\" height=\"562\" srcset=\"https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/BMW-M5-E39-Touring-03-750x562.jpg 750w, https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/BMW-M5-E39-Touring-03-1024x768.jpg 1024w, https:\/\/www.bmwblog.com\/wp-content\/uploads\/BMW-M5-E39-Touring-03.JPG 1600w\" sizes=\"auto, (max-width: 750px) 100vw, 750px\"\/><\/a><\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">What is confirmed is the car\u2019s place in history. BMW Group Classic acknowledges the E39 M5 was produced exclusively as a sedan, and that the Touring prototype remained a one of one. BMW M\u2019s own heritage materials note the Touring version was only ever made in prototype form.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">One car. One secret garage. And a room full of journalists who got to see, just once, what could have been.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Article Summary BMW secretly built a one-off E39 M5 Touring prototype packing the sedan&#8217;s 5.0-liter S62 V8 with 400 horsepower and 500 Nm of torque \u2014 but it never made it to production due to rear-axle dynamics compromises and concerns over market size.
