1970 'Cuda vs 1970 Challenger: The Mopar Sibling Rivalry
Two E-body platforms, one legendary rivalry — which Mopar deserves your garage?
Compare the 1970 Plymouth 'Cuda and 1970 Dodge Challenger head-to-head on styling, engines, performance, rarity, and current market value.
Brothers in Arms: The E-Body Story
In 1970, Chrysler launched its most ambitious muscle car platform yet — the E-body. Shared between Plymouth and Dodge, this architecture gave birth to two of the most desirable American cars ever built: the 'Cuda and the Challenger. While they share fundamental engineering, each car developed its own distinct personality, fan base, and market trajectory. The 'Cuda was the shorter, more aggressive street brawler, while the Challenger offered a slightly longer wheelbase and more grand-touring character. Understanding these differences is key to choosing the right one for your collection.
Engine Lineup Compared
Both cars had access to Chrysler's legendary engine family, but the packaging differed. The 'Cuda offered the famous 340 Six Pack, the 383, the 440 Six Barrel, and the ultimate Hemi. The Challenger R/T mirrored most of these options but also offered the unique SE (Special Edition) luxury package. The real headline is the 426 Hemi — available in both cars, it produced 425 hp and remains the single most iconic American muscle car engine ever built.
- 'Cuda 340: 275 hp — The balanced small-block option, light and rev-happy
- Challenger R/T 383: 335 hp — The standard big-block, great low-end torque
- 'Cuda 440 Six Barrel: 390 hp — Triple two-barrel carbs on a massive wedge engine
- Challenger R/T 440 Magnum: 375 hp — Single four-barrel, smooth highway power
- 'Cuda 426 Hemi: 425 hp — The holy grail, fewer than 652 built across all body styles
- Challenger R/T 426 Hemi: 425 hp — Slightly more common but equally legendary
Design Philosophy
The 'Cuda rides on a 108-inch wheelbase — two inches shorter than the Challenger's 110. That doesn't sound like much, but it gives the 'Cuda a noticeably more compact, aggressive stance. The Challenger's extra length creates a more relaxed, elongated profile that some prefer for its GT character. Both cars feature Chrysler's signature 'coke bottle' fender lines, but the 'Cuda's grille is more pointed and predatory while the Challenger wears a wider, more refined face. The 'Cuda's rear treatment with its taillights integrated into the bumper is more distinctive; the Challenger's full-width taillight panel is cleaner.
Driving Experience
The 'Cuda's shorter wheelbase makes it feel more darty and responsive in corners. It transitions faster and feels more like a sports car than a cruiser. The Challenger, with its extra two inches and slightly heavier standard equipment, rewards a more relaxed driving style. On the highway, the Challenger is the more comfortable companion. At the drag strip, the 'Cuda's lighter weight (by about 50–80 lbs in comparable trim) gives it a fractional advantage. Both cars share the same torsion-bar front suspension and leaf-spring rear, so ride quality and handling fundamentals are very similar.
Current Market Values (2026)
This is where the cars diverge dramatically. The 'Cuda — particularly in Hemi and convertible form — commands some of the highest prices in the entire collector car market. A Hemi 'Cuda convertible sold for $3.5 million in 2024, making it one of the most expensive muscle cars ever auctioned. The Challenger, while still highly desirable, generally trades at a 20–40% discount to comparable 'Cuda models, making it arguably the better value.
- 'Cuda 340 hardtop: $70,000–$110,000
- Challenger R/T 383 hardtop: $55,000–$85,000
- 'Cuda 440 Six Barrel: $120,000–$200,000
- Challenger R/T 440 Six Pack: $90,000–$160,000
- 'Cuda Hemi hardtop: $250,000–$500,000+
- Challenger R/T Hemi hardtop: $180,000–$350,000
The Verdict: Which E-Body Should You Buy?
If pure investment potential is your priority, the 'Cuda — especially in high-option configurations — has historically outperformed. If you want more car for less money with virtually identical engineering, the Challenger R/T is the smarter buy. For street driving enjoyment, the 'Cuda's shorter wheelbase makes it slightly more engaging. For long-distance cruising and show presence, the Challenger's longer body and available SE luxury options are hard to beat. Both are blue-chip collectibles that will continue to appreciate. The best advice? Buy the one that makes you turn around and look at it after you park.
