What is the Dodge Magnum based on?
Chrysler LX platform
The Dodge Magnum is based on the rear-wheel-drive Chrysler LX platform with Chrysler executives confirming that structural elements of the car's foundation such as the toe board, safety cage architecture, as well as the load-path philosophy being utilized by then-partner, Mercedes-Benz.
Why was the Dodge Magnum discontinued?
The Dodge Magnum was discontinued due to low sales, competition from other models like the Charger, and a market shift towards SUVs. Chrysler's financial struggles during the 2008 economic crisis also led to the cancellation of less profitable models, and the Magnum was replaced by the Dodge Journey.
- Low sales and market trends: Sales declined after peaking in 2005, and the overall market for station wagons was shrinking as more consumers shifted to SUVs and crossovers.
- Internal competition: The Dodge Charger, which shared the same platform, was a much more popular car and likely cannibalized Magnum sales.
- Economic downturn: The 2008 financial crisis forced Chrysler to cut costs and discontinue unprofitable models to survive.
- Replacement model: The Dodge Journey was introduced to take the Magnum's place in the lineup.
Is the V8 Magnum a good engine?
Yes, the V8 Magnum is generally considered a good and reliable engine, especially the 5.9L and 5.2L models, but it has some well-known issues that require attention. Its strengths include good power for its era, affordability and availability of parts, and a reputation for longevity with proper care. The main drawbacks are common problems like intake manifold plenum gasket leaks, which cause oil burning, and the potential for cracked cylinder heads in some cases.
Pros
- Good power and torque: The Magnum V8 offered strong performance for its time, making it capable for both daily driving and towing.
- Reliability: It is known for being a robust and long-lasting engine, with many examples exceeding 300,000 miles when properly maintained.
- Affordable parts: The engines were produced in large numbers for many different Chrysler vehicles, meaning parts are widely available and relatively inexpensive.
Cons
- Plenum gasket leaks: A very common issue is the intake manifold plenum gasket failing, which allows oil to leak into the lifter valley and be consumed by the engine, leading to oil burning.
- Cracked cylinder heads: The factory cast-iron cylinder heads can be prone to cracking, especially on high-mileage engines.
- Lack of modern power: While powerful for its time, its horsepower and torque figures lag behind newer V8 engines from today's market.
Overall
The V8 Magnum is a solid, dependable engine, particularly if you find one with a well-maintained history. It is a workhorse that can last a very long time, but it's wise to budget for and be prepared to address the common problems, especially the intake plenum gasket leaks.
Is the Dodge Charger built on a Mercedes platform?
The Dodge Charger is not built on a Mercedes-Benz chassis, but rather on the Chrysler LX platform, which incorporated structural elements and suspension components from Mercedes-Benz during the DaimlerChrysler partnership. Specifically, the rear suspension design was based on the Mercedes-Benz W211 E-Class, and the five-speed automatic transmission and rear differential were also sourced from Mercedes-Benz. While the platform is Mercedes-derived, it has been heavily modified and redesigned by Dodge to meet the needs of the Charger and Chrysler 300.
- Shared platform components: The LX platform for the Charger and Chrysler 300 shares structural elements and some suspension and drivetrain components with Mercedes-Benz models from the era.
- Specific component examples: The Charger uses a five-link rear suspension from the Mercedes E-Class, along with a rear differential and a 5-speed automatic transmission from the Mercedes-Benz S-Class.
- Extensive modifications: The platform has been significantly modified and strengthened by Dodge over the years to suit the specific performance goals of the Charger and to align with the company's design philosophy.
- Not a direct carryover: While the connection is strong, it is inaccurate to say the Charger uses a direct Mercedes-Benz chassis. The platform has been extensively re-engineered.
