The Ford Aerostar 4.0 V6 Long 4 WD XL, produced from 1989 to 1997, represented a significant offering in Ford’s minivan lineup. Positioned as a more capable and spacious variant, the “Long” wheelbase model, combined with the 4.0-liter V6 engine and four-wheel drive, aimed to appeal to families needing both passenger and cargo space, along with all-weather capability. This particular trim, the XL, typically included a higher level of standard features compared to base models. The Aerostar competed directly with the Chrysler Caravan/Dodge Voyager and the Chevrolet Astro/GMC Safari, offering a distinctly Ford approach to the burgeoning minivan market.

Powertrain & Engine Architecture
The heart of the Aerostar 4.0 V6 XL was the 3.9-liter (3958 cc) Ford Essex V6 engine. This engine, internally designated as the 4.0L, was a naturally aspirated, 90-degree V6 featuring a cast iron block and aluminum cylinder heads. It utilized a multi-port fuel injection system, providing improved fuel efficiency and throttle response compared to earlier carbureted designs. The engine produced 155 horsepower at 4200 rpm and 298 Nm (219.79 lb-ft) of torque at 2400 rpm. The 4WD system was typically a part-time setup, engaging the rear wheels when needed for enhanced traction. The transmission was a four-speed automatic, chosen for its ease of use and suitability for family transportation. While not a performance-oriented transmission, it was generally reliable and provided adequate shifting for everyday driving.
Driving Characteristics
The Aerostar 4.0 V6 with the automatic transmission offered a comfortable, if not particularly sporty, driving experience. Acceleration was adequate for merging onto highways and passing slower traffic, but it wasn’t a quick vehicle. The automatic transmission’s gear ratios were geared towards fuel economy and smooth operation, rather than aggressive acceleration. The four-wheel drive system provided enhanced stability and traction in inclement weather, making it a practical choice for regions with snow or rain. Compared to the 3.0-liter V6 versions, the 4.0L offered noticeably more power, especially when fully loaded with passengers and cargo. However, it lacked the responsiveness of the five-speed manual transmission available on some models.
Equipment & Trim Levels
The XL trim level of the Aerostar 4.0 V6 Long 4 WD typically included features such as air conditioning, power windows and locks, an upgraded sound system, and enhanced interior trim. Upholstery was usually cloth, with options for leather available. The “Long” wheelbase provided significantly more cargo space behind the third row of seats compared to the standard wheelbase models. Optional extras included a rear entertainment system, cruise control, and a heavy-duty towing package. The interior design was functional and family-oriented, with durable materials and ample storage compartments.
Chassis & Braking
The Aerostar utilized a body-on-frame construction, which contributed to its durability and towing capacity. The front suspension featured an independent double wishbone design, while the rear suspension employed a solid axle with coil springs. This setup provided a reasonably comfortable ride, although it wasn’t as refined as the fully independent suspensions found in some competing minivans. Braking duties were handled by ventilated discs at the front and drum brakes at the rear. Anti-lock brakes (ABS) were included as standard equipment on the XL trim, enhancing safety. Steering was hydraulic power-assisted, providing relatively light and easy steering effort.
Market Reception & Comparison
The Aerostar 4.0 V6 Long 4 WD XL received generally positive reviews for its spacious interior, comfortable ride, and all-weather capability. Critics noted that the 4.0-liter V6 provided sufficient power for most driving situations, but some found the automatic transmission to be somewhat sluggish. Fuel economy was typical for a large, four-wheel drive minivan of the era, averaging around 16-18 mpg in combined driving. Compared to the 3.0-liter V6 models, the 4.0L offered a significant performance advantage, but at the cost of slightly lower fuel economy. The Aerostar’s body-on-frame construction, while durable, also contributed to a higher curb weight compared to some unibody competitors.
Legacy
The Ford Aerostar, while eventually replaced by the Windstar, remains a fondly remembered minivan for many owners. The 4.0-liter V6 engine, when properly maintained, proved to be a relatively reliable powertrain. However, like many vehicles of its age, it is susceptible to age-related issues such as corrosion and wear on rubber components. Today, well-maintained Aerostars are becoming increasingly sought after by collectors and enthusiasts, particularly those looking for a classic American minivan with all-wheel drive capability. Parts availability is generally good, although some specific trim pieces may be difficult to find. The Aerostar’s robust construction and spacious interior continue to make it a practical and appealing choice for those seeking a vintage family vehicle.
