Continuing on my all-wheel ‘driveatribe’, I’d be remiss to not discuss BMW’s take on moving power around to all four wheels. While BMW wouldn’t launch the U.S.-spec iX until 1988, Europeans were introduced to the concept in 1986 – the same year as the Golf syncro. Unlike Audi’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 Audi’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. BMW’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.
Compared to other E30 models, the 325iX was a slow seller – BMW moved just 6,346 over the four production years between 1988 and 1991, putting these on just about equal footing with the M3 in terms of rarity. But two factors make finding clean ixs even harder; where they were used, and how they were used both result in rust being a big concern and it’s hard to find low-mileage examples. But while the odometer reading is stratospheric on today’s first-year ’88 2-door, it’s undergone a never-seen full restoration to return it to unbelievable condition. Also unbelievable? The price…
