How fast is the Dodge Magnum?

The Dodge Magnum’s speed depends on the engine and configuration; the fastest factory version with the 5.7-liter Hemi can sprint from 0 to 60 mph in roughly 6 seconds and reach top speeds around 140–150 mph, while base models with smaller engines are notably slower. The Magnum was produced from 2005 to 2008 and offered several powertrains aimed at balancing practicality with performance.

Engine options and performance

Overview of the main powertrains and their general performance figures.

• 2.7-liter V6: about 190 horsepower and roughly 180–200 lb-ft of torque. This was the base engine and prioritizes efficiency over outright speed.


• 3.5-liter V6: about 250 horsepower and around 250 lb-ft of torque. A step up that improves acceleration noticeably over the smallest engine.


• 5.7-liter Hemi V8 (RT): about 345 horsepower and roughly 375 lb-ft of torque. The quickest option, delivering the strongest straight-line performance.

Notes: horsepower and torque figures can vary slightly by model year and market, and the actual performance depends on transmission, gearing, tires, and vehicle condition. The Magnum’s wagon body style and weight influence real-world acceleration even with the V8.

Performance benchmarks by variant

To give readers a sense of acceleration and speed, here are commonly cited factory-era numbers by engine. Real-world results can vary based on conditions and equipment.

• 0–60 mph:
  
  
  
  • 2.7L V6: roughly 9.5–10.5 seconds
  
  
  • 3.5L V6: roughly 7.0–7.5 seconds
  
  
  • 5.7L Hemi V8: roughly 5.8–6.5 seconds
  
  
  
  


• Top speed (where permitted by gearing and electronics):
  
  
  
  • 2.7L V6: about 125–130 mph
  
  
  • 3.5L V6: about 130–140 mph
  
  
  • 5.7L Hemi V8: about 140–150 mph
  
  
  
  

These ranges summarize the Magnum’s performance spectrum across its main configurations. The faster versions deliver a brisk pace for a mid-2000s wagon, while the smaller engines emphasize daily practicality and efficiency.

Historical context and availability

The Dodge Magnum was produced from 2005 through 2008, built on the Chrysler LX platform as a wagon variant of the Charger/RWD lineup. It never entered mass production with a true high-performance SRT version; the performance emphasis came mainly from the V8-powered RT model. Reviews from the era praised its combination of cargo space and surprisingly strong straight-line speed for a large wagon, though handling and agility were not in the same league as contemporary sports cars.

Today, the Magnum remains a niche collectible for enthusiasts who value rear‑ticket practicality paired with American muscle-car grunt. Dodge did not revive the Magnum name as a new wagon in later generations, but its blend of space and speed remains a point of reference for mid‑2000s performance wagons.

Summary

In summary, the Dodge Magnum’s speed depends heavily on the engine choice. The 5.7-liter Hemi RT is the fastest, delivering confident acceleration and a top-end in the upper 140s to around 150 mph. The smaller 2.7L and mid-range 3.5L engines offer progressively slower, but still respectable, performance for a wagon. Across its 2005–2008 production window, the Magnum balanced practicality with a surprising degree of straight-line speed, making it a notable chapter in Dodge’s muscle‑car era.

How much horsepower does a Dodge Magnum 5.7 have?

340-horsepower
The Magnum R/T RWD comes with a 340-horsepower 5.7-Liter HEMI multi-displacement engine, five-speed AutoStick automatic transmission, touring suspension, performance anti-lock four-wheel disc brakes and rear-wheel drive.

How fast is a 2005 Dodge Magnum RT?

The top speed of a 2005 Dodge Magnum RT is 155 mph (250 km/h), as it was electronically limited by the factory. While the 5.7L Hemi engine is capable of more, the limiter prevents the vehicle from exceeding this speed. The SRT8 version, which was produced in later years and not 2005, could reach a higher top speed of around 170 mph. 

• 2005 Magnum RT (5.7L Hemi): The top speed is electronically limited to 155 mph (250 km/h). 
• Magnum SRT8 (later years): This model is capable of a top speed of approximately 170 mph (273 km/h), according to sources on YouTube and Forza Community Forums. 

Is the 5.9 V8 Magnum a good engine?

Yes, the 5.9 Magnum is generally considered a good, reliable, and powerful engine, especially when it receives proper maintenance. It is known for its low-end torque and durability, with many owners reporting high mileage, but it does have some common issues like intake manifold and exhaust manifold bolt problems. While its fuel economy is poor, its overall strength and longevity make it a solid choice if properly cared for. 
Pros of the 5.9 Magnum

• Power and torque: It offers excellent low-end torque and was one of the most powerful V8s of its time, making it great for towing and hauling. 
• Durability: The engine is known for its robustness and can last for hundreds of thousands of miles with proper maintenance. 
• Parts availability: The 5.9 Magnum was used in many Dodge vehicles, so parts are relatively inexpensive and easy to find. 

Cons of the 5.9 Magnum

• Fuel economy: It is not fuel-efficient, typically averaging around 12-13 mpg. 
• Common issues: A major known weakness is the plenum gasket leak on the intake manifold. Another common problem is broken exhaust manifold bolts, particularly on the passenger side. 
• Head cracks: The original cylinder heads are prone to cracking, especially if the engine is overheated or abused. 

How to maintain and improve the 5.9 Magnum

• Address the plenum gasket: Replace the stock plenum gasket with an upgraded aftermarket one to prevent leaks. 
• Check exhaust manifold bolts: Inspect and replace broken or rusted exhaust manifold bolts. 
• Perform regular maintenance: Change the oil, filter, and other fluids regularly. 
• Avoid abuse: The engine is not a high-performance racing engine. Driving it aggressively can lead to cracked heads. 
• Consider aftermarket heads: If replacing heads, consider aftermarket options to improve performance and durability.
