The BMW 3 Series Touring (E30), specifically the 325iX variant produced from 1988 to 1993, represents a significant expansion of the iconic 3 Series lineup. Introduced as BMW’s first all-wheel-drive wagon, the 325iX aimed to combine the practicality of a station wagon with the performance and handling BMW was becoming renowned for. This model, based on the E30 chassis (which received a facelift in 1987), offered a unique proposition in the European market, appealing to buyers seeking a versatile vehicle capable of handling diverse road conditions. The 325iX sat at the upper end of the E30 Touring range, offering a substantial performance upgrade over the base models.

Powertrain & Engine Architecture
The heart of the 325iX is the M20B25, a 2.5-liter inline-six engine. This engine, a cornerstone of BMW’s engineering prowess during the 1980s and early 1990s, features a cast-iron block and an aluminum cylinder head. It utilizes multi-port fuel injection, delivering a precise fuel mixture for optimal combustion. The M20 engine is known for its smooth power delivery and robust construction. The 325iX’s version produces 170 horsepower at 5800 rpm and 222 Nm (163.74 lb-ft) of torque at 4300 rpm. The engine’s all-aluminum head features two valves per cylinder, operated by a single overhead camshaft. The five-speed manual transmission was the only transmission option offered, providing a direct connection between the engine and the all-wheel-drive system.
Driving Characteristics
The 325iX offered a distinct driving experience compared to its rear-wheel-drive counterparts. The all-wheel-drive system, a viscous coupling type, provided enhanced traction, particularly in inclement weather or on slippery surfaces. While the added weight of the AWD system (approximately 150 lbs over the RWD models) slightly impacted acceleration, the improved grip translated to more confident handling and stability. The 325iX wasn’t a sports car in the purest sense, but it offered a balanced and engaging driving experience. The five-speed manual transmission provided precise gear changes, and the engine’s torque curve allowed for effortless cruising. Compared to the higher-output 328i, the 325iX prioritized usability and all-weather capability over outright performance.
Equipment & Trim Levels
The 325iX was generally well-equipped for its time. Standard features included power windows, central locking, and an upgraded sound system. The interior typically featured cloth upholstery, although leather was available as an option. The dashboard layout was typical of the E30, with a functional and driver-focused design. Optional extras included a sunroof, air conditioning, and upgraded audio systems. The 325iX trim level was positioned as a premium offering within the E30 Touring range, reflecting its advanced all-wheel-drive system and enhanced features.
Chassis & Braking
The E30 Touring chassis was modified to accommodate the all-wheel-drive system. The rear suspension was revised to incorporate a rear differential and driveshafts. The 325iX featured disc brakes on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) was standard, further enhancing safety. The suspension utilized coil springs and shock absorbers, offering a comfortable yet controlled ride. The steering was hydraulically assisted, providing light and precise steering feel.
Market Reception & Comparison
The 325iX was well-received in markets where all-wheel-drive was highly valued, such as Germany, Switzerland, and Canada. Critics praised its handling, stability, and practicality. However, the added weight and slightly higher price compared to the rear-wheel-drive models were noted. Fuel economy, at around 24 mpg combined, was reasonable for the time but not exceptional. Compared to the 325i (rear-wheel drive), the 325iX offered superior traction and all-weather capability, while the 328i provided more outright performance. The 325iX appealed to buyers who prioritized safety, practicality, and confident handling over pure speed.
Legacy
The BMW 325iX Touring holds a special place in BMW history as the company’s first all-wheel-drive wagon. The M20 engine is known for its durability and relatively simple maintenance requirements. Today, well-maintained examples are sought after by enthusiasts and collectors. While not as common as the rear-wheel-drive E30s, the 325iX offers a unique and rewarding driving experience. The all-wheel-drive system, while not as sophisticated as modern systems, remains effective and reliable. The 325iX represents a pivotal moment in BMW’s evolution, demonstrating the company’s willingness to innovate and expand its product offerings.
