2008-2009 Chrysler Aspen 4.7 i V8 16V (303 Hp) FlexFuel 4WD Automatic

Technical Specifications

The Chrysler Aspen 4.7i V8 4WD Automatic was produced for a limited time, spanning the 2008 and 2009 model years. It represented Chrysler’s entry into the full-size SUV segment, designed to compete with established models from General Motors and Ford. The Aspen shared its platform with the Dodge Durango, but aimed for a more refined and upscale experience. This particular variant, equipped with the 4.7-liter V8 engine, a four-speed automatic transmission, and four-wheel drive, was positioned as a mid-range offering, balancing capability with affordability. It was intended to appeal to families needing substantial space and towing capacity, with the added benefit of FlexFuel capability.

Powertrain & Engine Architecture

The core of the Aspen 4.7i is the 4.7-liter (286.99 cubic inches) V8 engine, designated with the engine code EVD. This engine is a member of Chrysler’s third-generation 4.7L family, featuring a robust cast iron block and lightweight aluminum cylinder heads. The engine utilizes a single overhead camshaft (SOHC) valvetrain with two valves per cylinder, a design chosen for its simplicity and reliability. Fuel delivery is handled by a multi-port fuel injection system, ensuring precise fuel metering for optimal performance and efficiency. The engine generates 303 horsepower at 5650 rpm and 329.69 lb-ft of torque at 3950 rpm. A key feature of this engine is its FlexFuel capability, allowing it to operate on gasoline or blends containing up to 85% ethanol (E85). The four-speed automatic transmission, while proven and durable, is a relatively older design compared to the five- or six-speed automatics becoming common at the time.

Driving Characteristics

Behind the wheel, the Aspen 4.7L 4WD Automatic offered a comfortable and capable driving experience, though it wasn’t particularly sporty. Acceleration was adequate for everyday driving and highway merging, but noticeably slower than the 5.7L HEMI-equipped models. The four-speed automatic transmission, while reliable, lacked the responsiveness and efficiency of more modern gearboxes. This resulted in slightly higher engine speeds during highway cruising and less precise gear selection. The four-wheel-drive system provided enhanced traction in various weather conditions and on slippery surfaces, making it a confident all-season vehicle. Towing performance was a strong suit, with the Aspen capable of handling substantial loads. The body-on-frame construction contributed to a comfortable ride, absorbing bumps and imperfections in the road, but also resulted in some body roll during cornering.

Equipment & Trim Levels

The standard equipment list for the 4.7i V8 4WD Aspen included features such as air conditioning, power windows and locks, a CD player with an auxiliary input jack, and cloth upholstery. Stepping up to the Limited trim level added more luxurious appointments, including leather upholstery, heated front seats, a premium sound system, and automatic climate control. Optional extras included a rear-seat DVD entertainment system, a power sunroof, and upgraded alloy wheels. Safety features were comprehensive, including anti-lock brakes (ABS) and multiple airbags. The interior design prioritized functionality and spaciousness, offering ample room for passengers and cargo. While the materials used were of good quality for the price point, they didn’t quite match the luxury found in some competing SUVs.

Chassis & Braking

The Aspen’s chassis employed a traditional body-on-frame construction, providing a robust and durable foundation. The front suspension utilized an independent torsion bar setup with a double wishbone design, while the rear suspension featured a coil spring and elastic beam configuration. This combination aimed to balance ride comfort with handling stability. The braking system consisted of ventilated discs at the front and solid discs at the rear, providing adequate stopping power. Anti-lock brakes (ABS) were standard, enhancing braking control in emergency situations. The steering system was a rack-and-pinion design, offering responsive steering feel. The Aspen’s substantial weight (2305 kg / 5081.66 lbs) contributed to its stable handling characteristics, but also limited its agility.

Market Reception & Comparison

The Chrysler Aspen, including the 4.7L V8 variant, received a mixed reception from automotive critics. While its spacious interior, comfortable ride, and towing capacity were praised, the outdated four-speed automatic transmission and relatively poor fuel economy were common criticisms. Compared to the 5.7L HEMI-equipped Aspen, the 4.7L version offered less power and performance, but at a lower price point. Fuel economy was slightly better with the 4.7L engine, though still not competitive with more modern SUVs. When compared to rivals like the Chevrolet Tahoe and Ford Expedition, the Aspen offered a competitive price but often lacked the refinement, features, and brand recognition of those established models.

Legacy

The Chrysler Aspen was discontinued after only two model years, due to declining sales and the introduction of more fuel-efficient and technologically advanced SUVs. The 4.7L V8 engine, while generally reliable, is known to be susceptible to certain issues, including oil leaks and potential cylinder head cracking. The four-speed automatic transmission, while durable, is less efficient than newer transmissions. Today, the Aspen 4.7L V8 4WD Automatic can be found on the used car market at relatively affordable prices. It remains a viable option for buyers seeking a spacious, capable SUV with towing capacity, but prospective buyers should be aware of the potential maintenance needs associated with the engine and transmission. Its brief production run and relatively low sales numbers have contributed to its status as a somewhat overlooked, yet capable, full-size SUV.
