Which Chrysler Aspen Version Should You Buy?
The Chrysler Aspen has a single generation, produced from 2006 through 2008 as an SUV 5-doors. Consequently, the meaningful buying decision is not between generations but between its four listed modifications: 4.7 AT RWD, 4.7 AT AWD, 5.7 AT RWD, and 5.7 AT AWD. The 5.7 AT offers substantially more power and torque, while the 4.7 AT versions are lighter.

Consequently, the meaningful buying decision is not between generations but between its four listed modifications: 4.7 AT RWD, 4.7 AT AWD, 5.7 AT RWD, and 5.7 AT AWD. The 5.7 AT offers substantially more power and torque, while the 4.7 AT versions are lighter. Choosing RWD minimizes kerb weight; choosing AWD increases both kerb and gross weight. Reliability, interior equipment, prices, and availability are not measured in the supplied data, so they cannot support a recommendation here.
Chrysler Aspen generations: what changed?
There is only 1 generation of the Chrysler Aspen in the catalogue, covering 2006–2008. It uses the SUV 5-doors body and contains four versions. No separate restyling or later generation is listed, so a buyer comparing a Chrysler Aspen 2007 with a Chrysler Aspen 2008 is comparing vehicles from the same generation. Changes between individual model years are not measured.
Searches for a Chrysler Aspen 2009, Chrysler Aspen 2026, or Chrysler Aspen hybrid refer to configurations outside the supplied production data. Hybrid specifications are not measured, and the catalogue does not list a generation produced after 2008.
Chrysler Aspen engine options and specs
Every listed Aspen has a front, longitudinal, naturally aspirated Gasoline V-shaped engine with 8 cylinders, 2 valves per cylinder, and Distributed injection (multi-point). Every version also uses an Automatic gearbox with 5 gears. The differences that matter are engine displacement, output, drive system, and weight.
| Version | Power | Torque | Displacement | Fuel | Cylinders and layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|
| 4.7 AT | 234 hp (172 kW) at 4600 rpm | 393 Nm at 3600 rpm | 4701 cm³ | Gasoline | 8, V-shaped | No | Automatic, 5 gears | RWD |
| 4.7 AT | 234 hp (172 kW) at 4600 rpm | 393 Nm at 3600 rpm | 4701 cm³ | Gasoline | 8, V-shaped | No | Automatic, 5 gears | AWD |
| 5.7 AT | 340 hp (250 kW) at 5200 rpm | 502 Nm at 4200 rpm | 5654 cm³ | Gasoline | 8, V-shaped | No | Automatic, 5 gears | RWD |
| 5.7 AT | 340 hp (250 kW) at 5200 rpm | 502 Nm at 4200 rpm | 5654 cm³ | Gasoline | 8, V-shaped | No | Automatic, 5 gears | AWD |
The 5.7 AT adds 106 hp, 78 kW, and 109 Nm over the 4.7 AT. Its displacement is 953 cm³ greater. Calculated from the catalogue figures, the 4.7 AT produces about 49.8 hp per litre, whereas the 5.7 AT produces about 60.1 hp per litre. The 5.7 AT therefore provides about 10.3 more hp per litre, in addition to its higher total output.
The 4.7 AT has a compression ratio of 9 and a bore and stroke of 93 × 86.5. The 5.7 AT has a compression ratio of 9.6 and a bore and stroke of 99.5 × 90.9. Engine-oil specifications, engine-swap compatibility, and engine-bay measurements are not measured.
Chrysler Aspen performance, mpg, and economy
Acceleration from 0–100 km/h is not measured for any 4.7 AT or 5.7 AT version. City, highway, and combined fuel consumption are also not measured for every version. CO₂ output and environmental class are not measured. This means the available specifications cannot establish which Aspen engine has better mpg or lower emissions.
A maximum speed of 180 km/h is listed for both the RWD and AWD 4.7 AT. Maximum speed is not measured for either 5.7 AT. The absence of a 5.7 AT figure should not be interpreted as evidence that it is slower or faster.
The output-to-weight comparison is more useful than an unsupported acceleration estimate. The 4.7 AT RWD carries about 9.40 kg per hp, while the 4.7 AT AWD carries about 9.72 kg per hp. The 5.7 AT RWD carries about 6.53 kg per hp, and the 5.7 AT AWD carries about 6.82 kg per hp. On the supplied numbers, both 5.7 AT versions have a clearly stronger power-to-weight relationship than their 4.7 AT equivalents.
Chrysler Aspen dimensions, weight, and capacity
Exterior dimensions, including length, width, and height, are not measured. Ground clearance and wheel sizes are also not measured for all four versions. Each version has a 102-litre tank.
| Version | Drive | Kerb weight | Gross weight | Ground clearance | Tank | Wheel sizes |
|---|---|---|---|---|---|---|
| 4.7 AT | RWD | 2200 kg | 2948 kg | not measured | 102 litres | not measured |
| 4.7 AT | AWD | 2275 kg | 3039 kg | not measured | 102 litres | not measured |
| 5.7 AT | RWD | 2220 kg | 2948 kg | not measured | 102 litres | not measured |
| 5.7 AT | AWD | 2320 kg | 3039 kg | not measured | 102 litres | not measured |
Moving from the 4.7 AT RWD to the 4.7 AT AWD adds 75 kg of kerb weight. Moving from the 5.7 AT RWD to the 5.7 AT AWD adds 100 kg. For either engine, AWD raises gross weight from 2948 kg to 3039 kg, a difference of 91 kg.
Among RWD versions, the 5.7 AT weighs only 20 kg more than the 4.7 AT while adding 106 hp and 109 Nm. Among AWD versions, the 5.7 AT weighs 45 kg more than the 4.7 AT for the same output gains. These comparisons strongly favor the 5.7 AT when engine output relative to vehicle weight is the priority.
All versions use Independent, spring front suspension and Dependent, spring rear suspension. Front and rear brakes are Disc across the range, so the supplied chassis specifications do not distinguish one engine or drive configuration from another.
Chrysler Aspen reliability and problems
Reliability records, common problems, maintenance costs, repair history, and owner-survey results are not measured. The data therefore provides no factual basis for declaring the 4.7 AT, the 5.7 AT, RWD, or AWD more reliable. A used-car decision should not treat engine size, power, or lower kerb weight as a substitute for reliability evidence.
Interior specifications and trim-level equipment are likewise not measured. Consequently, searches for a Chrysler Aspen interior or Limited specifications cannot be answered from this dataset, and equipment differences should be checked separately for an individual vehicle.
Which Chrysler Aspen version should you buy?
For the strongest numerical case, choose the 5.7 AT RWD. It combines 340 hp and 502 Nm with a kerb weight of 2220 kg, giving the best weight-per-horsepower figure in the range at approximately 6.53 kg per hp. Compared with the 4.7 AT RWD, it supplies 106 hp and 109 Nm more while adding only 20 kg.
Choose the 5.7 AT AWD when AWD is required and engine performance remains the priority. It retains 340 hp and 502 Nm, but its 2320 kg kerb weight is 100 kg above that of the 5.7 AT RWD. Its approximate 6.82 kg per hp remains better than either 4.7 AT version.
Choose the 4.7 AT RWD when the lowest listed kerb weight matters more than maximum output. At 2200 kg, it is the lightest Aspen in the data. It produces 234 hp and 393 Nm, reaches a listed maximum speed of 180 km/h, and weighs 75 kg less than the 4.7 AT AWD.
Choose the 4.7 AT AWD only when the combination of the 4.7 AT engine and AWD specifically matches the requirement. It has the same 234 hp and 393 Nm as the 4.7 AT RWD but weighs 2275 kg, making it 75 kg heavier. No fuel-consumption or reliability figure is available to show that this configuration compensates for its extra weight elsewhere.
In short, the 5.7 AT RWD is the output-focused choice, the 5.7 AT AWD pairs the stronger engine with AWD, and the 4.7 AT RWD is the lightest option. Prices are not supplied, so “what the extra money buys” cannot be quantified financially; what the larger engine demonstrably buys is 106 hp, 109 Nm, and a better power-to-weight ratio.
