Red fastback and black coupe—representing Ford Mustang GT and Dodge Challenger R/T—driving side-by-side on a desert highway at sunset, no logos or text.

Introduction:

Two icons, two playbooks. The Ford Mustang GT (S650) pushes modern handling and tech; the Dodge Challenger R/T (Last Call, 2023) doubles down on retro charm and V8 rumble. Here’s a concise, data-driven comparison to help enthusiasts pick their poison.

Line-Up & Context

  • Mustang GT: Current-gen (S650), 5.0L “Coyote” V8, 6-MT or 10-AT, broad dealer availability.

  • Challenger R/T: 375 hp & 410 lb-ft from the 5.7L HEMI.

Real-world quickness

  • 0–60 mph (tested): Mustang GT ~4.2 s (auto, performance exhaust); Challenger R/T typically ~5.0–5.3 s depending on spec and tires.
  • Quarter-mile (tested): Mustang GT around 12.5 s @ ~114 mph; R/T commonly mid-13s @ ~103–105 mph.

Transmission & Character

  • Mustang GT: 6-speed manual (rev-matching) or 10-speed automatic; aggressive gearing and advanced drive modes aid launch and pace.
  • Challenger R/T: 6-speed manual or 8-speed automatic; tall gearing, relaxed shifts; excels in straight-line surge and highway loafing.

Chassis, Handling & Brakes

  • Mustang GT: Lighter, shorter wheelbase; eager turn-in and strong skidpad grip; optional MagneRide and Performance Pack sharpen response.
  • Challenger R/T: Bigger, heavier grand-tourer feel; stable straight-line cruiser; braking and corner entry require more distance and patience.

Practicality & Cabin

  • Mustang GT: 2+2 layout with supportive seats; adequate trunk (coupe) for weekend bags.
  • Challenger R/T: Class-leading space for a muscle coupe; real adult-friendly rear seat and a huge 16.2 cu ft trunk.

  • Mustang GT (5.0L): EPA combined 17–19 mpg (manual/auto). Premium recommended.
  • Challenger R/T (5.7L): EPA combined 18 mpg (manual) or 19 mpg (auto).

Tip: Highway cruising narrows the gap; city driving widens it.

Ownership Reality (2025+)

  • Buying new: Mustang GT is current and widely available in multiple trims.
  • Buying Challenger R/T: Focus on late-build 2023 examples; verify “Last Call” items, mileage, and service history.
