The Secret BMW M8 Is The Only V12 Powered M-Car Ever Made: The E31 Story — Jason Cammisa Revelations

This is the history of the BMW E31 8-series, including a special M8 model that lacked any M badging. The 850CSi received the same M-treatment as the E36 M3, but nobody knows it was, legally, an M8. === If you like this content, we'd love to have you join Hagerty Driver's Club!

The 850i was one of, if not the, most technologically advanced cars in the world. Its list of industry firsts is enormous, and includes drive-by-wire, CAN-bus technology, and the first German V-12 in 50 years. But BMW forgot to install the fun. the 850i was a sales disaster. At its debut in 1989 at the Frankfurt Auto Show IAA, BMW received 35,000 orders — enough to sell out 3 years of planned production. However, once the car magazines drove it, the reviews were brutal and customers cancelled their orders. (Largely in favor of the R129-chassis Mercedes SL.) 850i sales were so poor that BMW cancelled plans to make an E31 convertible, and also killed off the planned M8, which used the McLaren F1's S70/2 640-hp V-12 with ITBs and carbon intakes. Instead, M engineered a less-expensive M8, the formula for which was duplicated exactly for the US-market E36 M3: an M engine (the S70B56 — bored and stroked to 5.6 liters, with hot cams and high compression), a 6-speed manual with short gearing and LSD, quicker steering, and a full suspension and brake upgrade. Also, European versions got "AHK," which is rear-wheel steering — and were homologated for sale as the M8/E, produced by BMW Motorsport GmbH. The reviews were outrageously positive — and the car sold out. But most enthusiasts don't know it even exists, because the badge didn't say M8. It said BMW 850CSi — chosen to celebrate earlier M cars like the M635 CSi. With 380 hp and 406 lb-ft of torque, the CSI certainly had power, but BMW hadn't yet discovered the Power of the M Badge. The BMW E31 was sold as the 850i (M70 5.0-liter V12), the 850Ci (M73 5.4-liter V12, automatic only), and the 840Ci (both M60B40 and M62B44 4.0 and 4.4-liter V-8s, automatic only.) The 850CSi was available only with the 5.6-liter V-12 and a 6-speed manual.
