While BMW wouldnâ€™t launch the U.S.-spec iX until 1988, Europeans were introduced to the concept in 1986. Unlike Audiâ€™s quattro system which utilized a rearward driveshaft tacked on to a front-wheel drive transmission output shaft, BMW mated a transfer case and two viscous couplings, which effectively were front and rear limited-slips. This was very different from Audiâ€™s contemporaneous system, which relied on the driver to lock the rear and center differentials that were otherwise open. The 325iX was able to be mated to an automatic transmission long before Audi would do so in the small chassis. BMWâ€™s system was also more rearward biased, with 67% of the power being sent to the back wheels. While still more prone to understeer than a standard 325i, it was less so than the Audi.
But outside, there was little fanfare to celebrate the massive change in drivetrain technology. The iX just got a simple lower body kit similar to the Scirocco 16V kit and a single “X” after the 325i designation on the trunk. That’s it. European examples could even be more stealthy, like this ’86 that sports wheel covers. And this one in particular is quite special, as it’s never been road registered and has traveled just 500km since new. Pricing? The ‘E30 Tax’ is strong, my friends.
