The Last True Muscle Car

The 2018 Dodge Challenger occupies a unique position in the automotive landscape - a genuinely large, unapologetically powerful muscle car in an era of downsized turbocharged everything. While competitors chased efficiency and handling, Dodge doubled down on displacement and power, culminating in the 840 hp Demon launching this model year.

For used buyers, the Challenger offers something increasingly rare: V8 muscle car experience at accessible prices. The platform is proven reliable, parts are plentiful, and depreciation has made even high- performance variants accessible. Whether you want a comfortable V6 cruiser or a supercharged monster, the Challenger lineup has options.

SXT: Entry Point

The base SXT features the 3.6L Pentastar V6 producing 305 horsepower - adequate for a car this size but missing the muscle car soul. Available with RWD only (AWD requires GT). Good for buyers who want the styling without V8 costs. The V6 is smooth and efficient but the exhaust note reveals its lack of cylinders.

GT: All-Weather Muscle

GT adds all-wheel drive to the V6 Challenger - the only way to get AWD in this platform. It includes sport suspension, larger brakes, and unique styling. For buyers in snow states who need AWD but want Challenger styling, GT is the only option. The AWD system is effective but adds weight.

R/T: Our Recommendation

R/T is where Challenger comes alive. The 5.7L HEMI V8 produces 375 horsepower with that distinctive HEMI rumble. Fuel economy is reasonable for a V8 (19/30 mpg with the 8-speed). Insurance costs remain manageable. R/T delivers the muscle car experience without Scat Pack pricing. Available with manual or automatic transmission.

R/T Scat Pack: Performance Value

Scat Pack upgrades to the 6.4L HEMI producing 485 horsepower - a massive jump from R/T. Includes bigger Brembo brakes, sport suspension, and performance exhaust. For buyers wanting serious straight-line performance, Scat Pack delivers 90% of SRT experience at significant savings. The widebody option adds aggressive fenders and wider tires.

SRT 392: Track Focused

SRT 392 shares the 6.4L HEMI with Scat Pack but adds active Bilstein suspension, launch control, SRT-specific interior, and refined calibration. Its more track-focused than Scat Pack with better weight distribution and tuning. Worth the premium for track day enthusiasts; Scat Pack is better value for street use.

SRT Hellcat: Supercharged Madness

The supercharged 6.2L HEMI produces 707 horsepower in standard form - enough to overwhelm the rear tires in most conditions. Hellcat is about straight-line acceleration and the supercharger whine that announces your presence. Insurance, fuel, and tire costs are substantial. For enthusiasts who understand what theyre buying, nothing else compares.

Based on current nationwide market listings

Engine Details

3.6L Pentastar V6

The 305 hp V6 is smooth, efficient, and proven reliable across millions of Chrysler products. It moves the Challenger adequately but without drama. Paired with the 8-speed automatic or available 6-speed manual (on SXT Plus). Fuel economy reaches 30 mpg highway.

5.7L HEMI V8

The 375 hp 5.7L delivers classic V8 character with modern efficiency features including Multi-Displacement System (MDS) cylinder deactivation. The distinctive HEMI exhaust note is part of the experience. Reliable with proper maintenance including cylinder deactivation system care.

6.4L HEMI V8

The 485 hp 6.4L (392 cubic inches) is a naturally-aspirated powerhouse. No turbo or supercharger means linear power delivery and excellent reliability. This engine can take significant abuse while delivering consistent performance. The larger displacement means more low-end torque than the 5.7L.

6.2L Supercharged HEMI

The Hellcat engine produces 707 hp through a 2.4L supercharger. Despite the extreme output, reliability has been good when maintained properly. The supercharger requires premium fuel and more frequent oil changes. Cooling system maintenance is critical.

Common Issues and Concerns

HEMI Tick

A ticking noise on cold startup is common on HEMI V8s, related to lifters and the MDS system. Its typically harmless but annoying. Some owners have lifters replaced; others live with it. Listen during test drive cold start and decide if it bothers you.

Transmission Behavior

The ZF 8-speed can exhibit hesitation during light acceleration as it hunts for the optimal gear. Software updates improve behavior. In Sport mode, the transmission is more decisive. Manual transmission eliminates this concern entirely.

Suspension Wear

Higher-mileage Challengers may develop suspension clunks from worn bushings and ball joints. These are wear items rather than defects. Budget for suspension refresh around 70K-80K miles. Performance variants wear suspension faster due to harder driving.

Buying Recommendations

Best Value Configuration

Target: 2018 Challenger R/T Plus, 40,000-60,000 miles, documented service history, stock condition. Price: $24,000-$30,000. This delivers the HEMI muscle car experience with reasonable costs.

Performance Value

Target: 2018 Challenger R/T Scat Pack, under 50,000 miles, stock or lightly modified. Price: $32,000-$38,000. The 485 hp 6.4L provides serious performance at attainable pricing.

Maximum Power

Target: 2018 Challenger SRT Hellcat, under 40,000 miles, documented maintenance. Price: $52,000-$62,000. Supercharged madness for enthusiasts who understand ownership costs.
