Engine and Performance Output

The 2018 Dodge Charger SRT 392 is powered by a 6.4-liter V8 engine that produces 485 horsepower and 475 pound-feet of torque. This engine pairs with an eight-speed automatic transmission and rear-wheel drive. The combination allows the vehicle to accelerate from 0 to 60 mph in approximately 3.6 seconds, with a top speed of 190 mph.

The engine uses a traditional gasoline fuel system with a fuel tank capacity of 18.5 gallons. Fuel consumption varies based on driving conditions, but the EPA rates the 2018 model at approximately 16 mpg in city driving and 25 mpg on the highway, with a combined rating of 19 mpg.

Key Takeaways

  • The 2018 Charger SRT 392 runs a 6.4-liter V8 engine producing 485 horsepower and 475 pound-feet of torque with an eight-speed automatic transmission.
  • EPA fuel economy ratings are 16 city, 25 highway, and 19 combined mpg, which reflects the vehicle's performance-oriented design.
  • The vehicle meets EPA Tier 2 emissions standards and carries a gross vehicle weight rating of approximately 4,500 pounds.
  • Annual registration and inspection requirements depend on your state, as emissions testing rules vary by location.

Emissions Standards and Classification

The 2018 Dodge Charger SRT 392 meets EPA Tier 2 Bin 8 emissions standards, which were the federal requirement for that model year. This classification means the vehicle was designed to control nitrogen oxides, particulate matter, and volatile organic compounds within limits set by the Environmental Protection Agency.

The vehicle is not classified as a low-emission vehicle (LEV) or zero-emission vehicle (ZEV), which means it does not may have access to for special incentive programs in states like California that offer tax credits or carpool lane access for cleaner vehicles. However, it remains street-legal in all 50 states and meets the baseline emissions requirements for registration and inspection.

Fuel Type and Tank Capacity

The 2018 Charger SRT 392 requires regular unleaded gasoline with an octane rating of 87 or higher. The fuel tank holds 18.5 gallons, which provides a driving range of approximately 350 to 465 miles depending on whether you are driving primarily on highways or in city conditions.

The vehicle does not have a hybrid or alternative fuel option. Dodge did not offer a plug-in hybrid or electric variant of the SRT 392 in 2018, so gasoline is the only fuel source available for this model.

Weight and Dimensions

The 2018 Charger SRT 392 has a gross vehicle weight rating (GVWR) of approximately 4,500 pounds. The vehicle itself weighs around 4,130 pounds, leaving roughly 370 pounds of capacity for passengers and cargo combined. These figures vary slightly depending on whether the vehicle has optional equipment like a sunroof or upgraded audio system.

The overall length is 200.3 inches, width is 75.7 inches, and height is 58.5 inches. The wheelbase measures 120 inches, which contributes to the vehicle's stable handling at high speeds despite its substantial weight.

Registration and Inspection Requirements

Registration and emissions testing requirements for the 2018 Charger SRT 392 depend on your state. Most states require annual or biennial vehicle inspections that include emissions testing, though some states have eliminated routine emissions tests for newer vehicles. A few states, including California and New York, have stricter emissions standards and may require more frequent testing.

When you register the vehicle, you will need to provide the vehicle identification number (VIN), proof of ownership, and proof of insurance. Some states charge higher registration fees for vehicles with larger engines or higher horsepower ratings, so check your state's Department of Motor Vehicles website for specific fee schedules.

Maintenance and Environmental Considerations

The 2018 Charger SRT 392 requires regular maintenance to keep emissions systems functioning properly. This includes scheduled oil changes (typically every 10,000 miles), air filter replacements, and spark plug service. The vehicle's catalytic converters and oxygen sensors are critical to emissions control and should be inspected during routine service.

If the check engine light appears, the vehicle's onboard diagnostic system has detected a problem that may affect emissions performance. A mechanic can read the diagnostic trouble code using a scanner to identify the specific issue. Addressing emissions-related problems promptly helps maintain fuel efficiency and keeps the vehicle compliant with state inspection standards.

Frequently Asked Questions

Does the 2018 Charger SRT 392 may have access to for any tax credits or incentives?

No. The 2018 Charger SRT 392 does not meet the criteria for federal or state tax credits because it is not a low-emission or alternative-fuel vehicle. Some states offer incentives only for electric vehicles, plug-in hybrids, or vehicles meeting LEV standards, which this model does not.

Can I drive the 2018 Charger SRT 392 in California?

Yes, the vehicle is street-legal in California and all other states. It meets federal emissions standards, though California has its own stricter standards. The 2018 model meets California's requirements for that year, so registration and inspection are handled the same way as in other states.

What happens if my vehicle fails an emissions test?

If the vehicle fails an emissions inspection, you will need to have it serviced by a mechanic before you can renew your registration. Common causes include a faulty oxygen sensor, a loose gas cap, or a problem with the catalytic converter. Once repairs are made, you can request a retest at your local inspection station.

How often do I need to get an emissions test?

This varies by state. Some states require annual testing, others every two years, and some have eliminated routine testing for vehicles newer than a certain model year. Check your state's Department of Motor Vehicles or environmental agency website to find the specific requirement for your location.

Is the 2018 Charger SRT 392 more fuel-efficient than earlier SRT models?

The 2018 model's 19 mpg combined rating is comparable to or slightly better than earlier SRT 392 generations, though fuel economy depends heavily on driving habits and conditions. Highway driving yields better mileage (25 mpg) than city driving (16 mpg) due to the engine's efficiency at steady speeds.
