What engines came in the 2007 Dodge Charger

The 2007 Dodge Charger offered three engine choices, each with different power output and fuel consumption. The base engine was a 2.7-liter V6 producing 190 horsepower and 190 pound-feet of torque. The mid-range option was a 3.5-liter V8 with 250 horsepower and 250 pound-feet of torque. The top-tier engine was a 5.7-liter HEMI V8 that generated 370 horsepower and 395 pound-feet of torque.

All three engines paired with a 5-speed automatic transmission. The 2.7-liter V6 was standard on base SE and SXT models. The 3.5-liter V8 came on the R/T trim, though some R/T models could be ordered with the HEMI. The 5.7-liter HEMI was standard on the SRT8 performance variant and available as an upgrade on R/T models.

Key Takeaways

  • The 2007 Charger came with a 2.7-liter V6, 3.5-liter V8, or 5.7-liter HEMI V8, each paired to a 5-speed automatic transmission.
  • The base V6 delivered 190 horsepower and achieved the best fuel economy of the three options, though real-world mileage varied by driving conditions.
  • The HEMI V8 produced 370 horsepower but consumed significantly more fuel, especially in city driving or heavy traffic.
  • Transmission reliability was generally solid across all three engines, though the HEMI's higher output meant more stress on drivetrain components over time.
  • Used 2007 Chargers with higher mileage often show transmission wear, so a pre-purchase inspection of the transmission's shift quality is worth the cost.

Fuel economy for each engine

The 2007 EPA ratings varied significantly by engine choice. The 2.7-liter V6 was rated at 17 miles per gallon city and 25 highway. The 3.5-liter V8 dropped to 16 city and 24 highway. The 5.7-liter HEMI V8 fell further to 14 city and 22 highway. These are EPA estimates; real-world mileage depends on driving style, traffic conditions, and maintenance.

Owners of HEMI-equipped Chargers often report fuel economy closer to 12 to 16 mpg in mixed driving, particularly in stop-and-go city conditions. Highway driving in a HEMI can reach the EPA estimate or slightly better if you maintain steady speeds. The V6 tends to perform closer to its EPA rating in real use, making it the most predictable choice if fuel cost is a primary concern.

Performance and acceleration

The 2.7-liter V6 accelerates from 0 to 60 mph in roughly 8.5 to 9 seconds, adequate for daily driving but noticeably slower than the V8 options. The 3.5-liter V8 cuts that time to approximately 7.5 to 8 seconds. The 5.7-liter HEMI achieves 0 to 60 in the 5.8 to 6.2 second range, a substantial jump that reflects the engine's 370 horsepower and the SRT8's performance-tuned suspension.

The HEMI's advantage extends to passing power and highway merging. The extra torque makes the Charger feel planted and responsive at speed. The V6, by contrast, requires more planning when merging on busy highways or passing slower traffic. The 3.5-liter V8 sits in the middle—adequate for most driving situations but without the reserve power of the HEMI.

Transmission durability and common issues

The 5-speed automatic transmission in the 2007 Charger is a Chrysler TorqueFlite unit that generally holds up well when maintained. Regular fluid changes every 30,000 to 60,000 miles extend its life significantly. However, some owners report delayed engagement or slight hesitation when shifting, particularly as mileage climbs past 100,000 miles.

The HEMI V8 puts more stress on the transmission than the V6 or 3.5-liter V8, so HEMI-equipped Chargers may show transmission wear sooner if the previous owner drove aggressively or neglected maintenance. When shopping for a used 2007 Charger, take it for a test drive and pay attention to shift smoothness, any clunking when shifting into Drive or Reverse, and whether the transmission hesitates when accelerating from a stop. A transmission fluid inspection can reveal whether the fluid is still red and clean or dark and burnt-smelling, which signals internal wear.

Maintenance costs and parts availability

Parts for the 2007 Charger remain widely available because the model is still common on used car lots and the Dodge platform was produced in high volume. Engine oil, filters, spark plugs, and brake components are inexpensive and straightforward to source from any auto parts retailer. Replacement engines and transmissions are also available from salvage yards at reasonable prices, which matters if you are considering a higher-mileage example.

Routine maintenance—oil changes, coolant flushes, and brake service—costs roughly the same as for other mid-size sedans from that era. The HEMI V8 requires premium fuel (91 or 92 octane), which adds to fuel costs but does not significantly change maintenance expenses. Suspension components, particularly control arms and bushings, can wear out by 100,000 miles, and replacement runs $300 to $800 depending on which parts need work.

Resale value and what to expect

A 2007 Charger with average mileage (around 120,000 to 140,000 miles) typically sells for $6,000 to $12,000 depending on condition, engine choice, and local market demand. HEMI-equipped models command a premium of $1,500 to $3,000 over comparable V6 or 3.5-liter V8 examples. SRT8 models, which came standard with the HEMI and performance upgrades, can reach $14,000 to $18,000 if well-maintained.

Condition matters more than mileage for this model. A well-maintained 2007 Charger with 150,000 miles and full service records will hold value better than a neglected example with 90,000 miles. Check the Kelley Blue Book or NADA Guides for your specific region, as prices vary by geography and local demand for muscle cars.

Comparing the 2007 Charger to its rivals

The 2007 Charger competed directly with the Pontiac Grand Prix, Buick Lucerne, and Chrysler 300. The Grand Prix offered similar engine options and performance but has become harder to find parts for since Pontiac ceased production in 2010. The Lucerne was more conservative in styling and performance but offered a smoother, more luxury-focused ride. The Chrysler 300 shared the Charger's platform and engines but commanded higher prices and attracted buyers seeking a more upscale interior.

If you prioritize raw performance and lower purchase price, the 2007 Charger HEMI undercuts the 300 while delivering comparable power. If you want better fuel economy and lower maintenance costs, the V6 Charger beats the V8 options but trails the Grand Prix in some performance metrics. The choice depends on whether you value acceleration and power or efficiency and affordability.

Frequently Asked Questions

Is the 2007 Charger V6 reliable for daily driving?

Yes. The 2.7-liter V6 is a proven engine with no major design flaws. It requires regular oil changes and coolant maintenance, but owners commonly report 150,000 to 200,000 miles without major repairs. The main wear items are the transmission and suspension components, not the engine itself.

How much does it cost to replace a transmission in a 2007 Charger?

A rebuilt transmission typically runs $1,500 to $2,500 installed, depending on your location and whether you use a dealer or independent shop. A used transmission from a salvage yard costs $800 to $1,200 plus installation. A new OEM transmission can exceed $3,500 before labor.

Can I use regular fuel in a 2007 Charger HEMI?

The HEMI is designed for premium fuel (91 or 92 octane) and will run on regular (87 octane), but you will lose performance and fuel economy. The engine's computer adjusts timing to prevent knock, which reduces power output. Stick with premium for best performance and efficiency.

What is the difference between the 2007 Charger R/T and SRT8?

The R/T came standard with the 3.5-liter V8 but could be ordered with the HEMI. The SRT8 came only with the HEMI and included performance suspension, upgraded brakes, and a more aggressive exterior. The SRT8 is faster and handles better but costs more to buy and maintain.

Should I buy a 2007 Charger with over 150,000 miles?

It depends on maintenance history. A well-documented example with regular oil changes and transmission service can be reliable. Get a pre-purchase inspection focusing on transmission smoothness, suspension wear, and engine compression. Avoid examples with no service records or evidence of hard driving.
