BMW’s second generation M5 followed the same recipe as the outgoing E28; manual transmission, rear-drive, howling inline-6 under the hood. But the E34 was far from a copy of the car that was really credited with being the first super sedan. BMW upped with power first with the 3.6 liter version of the S38; though the increase in displacement was a scant 82 ccs, the result was impressive. BMW Motorsport GmbH fit a new cam, a higher compression head, and a new engine management system to yield 311 horsepower at a rev-busting 6,900 rpms. They weren’t done.
In 1992 M upped the capacity again, this time to just 5 cc shy of 3.8 liters. Even higher compression, a further revision in electronic management, and a few other odds and ends now netted 340 horsepower and 300 lb-ft of torque. Again, they weren’t done. Perhaps tired of Audi cornering the go-fast-5-door market with their 200 20V Avant, in 1992 BMW launched the M5 Touring. Production began in March 1992 and ran through 1995. All E34 M5 Tourings were left-hand drive 3.8 models, and a total of 891 were produced.
BMW opted not to bring the enlarged motor or the M Touring model to the United States, as the 540i took over the top rungs of North American production. But now legal for importation, these rare Ms are one of the more desirable models around:
