The 2018 5.7 Hemi represents the mature evolution of Chrysler’s legendary pushrod V8, delivering dependable power and capability across its family of Ram trucks and Dodge SUVs. This naturally aspirated workhorse combines classic American muscle engineering with modern fuel management and emissions compliance, resulting in a powertrain built for both trailering adventures and daily commutes.
Technical Specifications and Output
Under the hood, the 2018 5.7 Hemi maintains its displacement at 5,654 cc, producing 395 horsepower and 410 pound-feet of torque. These figures are consistent across the Ram 1500 lineup and the Dodge Durango and Challenger variants that utilize this engine. The power is fed to the wheels through a reliable eight-speed automatic transmission, providing a balance of performance and fuel efficiency that suits both work and leisure driving requirements.
Fuel Economy and Efficiency
Efficiency is a strong point for the 2018 model year, with the Hemi-equipped Ram 1500 achieving an EPA-estimated 17 miles per gallon in the city and 23 miles per gallon on the highway. When equipped with the eTorque mild-hybrid system, which integrates a belt-driven starter generator, the engine can shut off at stops to conserve fuel. This setup results in an estimated 20 city / 26 highway MPG, a significant improvement over earlier generations.
Applications and Vehicle Compatibility
This robust engine was offered across multiple model lines in 2018, ensuring versatility for different consumer needs. It served as a top-tier option for the Ram 1500, providing ample power for towing and hauling duties. The same powertrain was also available in the Dodge Durango, offering families a blend of space, performance, and capability, while the Dodge Challenger utilized it to deliver engaging, rear-wheel-drive excitement.
Towing and Payload Capacity
One of the primary strengths of the 5.7 Hemi in the 2018 model year is its capability in demanding scenarios. The Ram 1500 equipped with this engine and the appropriate towing package can tow up to 7,730 pounds. Payload capacity reaches around 1,730 pounds, depending on the specific configuration and cab style. This makes the setup ideal for contractors, outdoor enthusiasts, and anyone who needs to move heavy equipment or recreational gear regularly.
Reliability and Maintenance
Mechanically, the 5.7 Hemi is renowned for its durability and straightforward design. The pushrod valve train reduces the number of components susceptible to high-RPM failure, contributing to a long service life. With proper maintenance, including regular oil changes and adherence to the scheduled service intervals, this engine is known to log high mileage without major issues, making it a trusted choice for used vehicle buyers.
Common Considerations and Ownership Costs
While generally reliable, owners should be aware of specific maintenance items. The 5.7 Hemi can be prone to lifter tick if not maintained with the correct oil viscosity and filtration. Spark plugs are another component that may require attention before the 100,000-mile mark due to the engine’s design. Parts availability is excellent, thanks to the engine’s long production history, ensuring that repairs can be conducted efficiently and cost-effectively.
Technology and Features
Incorporated within the 2018 model year, the 5.7 Hemi benefited from several technological upgrades. Variable valve timing (VVT) optimizes performance and efficiency across the rev range, while the aforementioned eTorque system aids in refinement. The engine is managed by a sophisticated engine control unit that balances power delivery, fuel economy, and emissions compliance, ensuring the powertrain meets stringent modern standards.
