The 2004 Miata specs outline a driving experience defined by its near-perfect 50/50 weight distribution, a naturally aspirated 1.8-liter engine producing 140 horsepower, and a lightweight curb weight of just 2,395 pounds. This specific model year represents the pinnacle of the original NC platform, offering a raw and engaging connection to the road that remains the benchmark for affordable sports cars. Understanding these specifications is key to appreciating why this generation of the MX-5 Miata continues to be a sought-after classic among driving enthusiasts.
2004 Mazda Miata Engine and Performance Specifications
At the heart of the 2004 model is the 1.8-liter MZR LF-VE inline-four engine, a refinement of the legendary rotary-style powerplant known for its high-revving nature and linear power delivery. The official 2004 Miata specs detail a compression ratio of 9.5:1, paired with a multi-port fuel injection system that ensures efficient combustion across the rev range. Power is rated at 140 horsepower at 6,500 rpm, while torque peaks at 127 lb-ft at 4,000 rpm, providing a responsive and eager acceleration from any gear.
Drivetrain and Dimensional Specifications
The standard transmission is a five-speed manual, though a four-speed automatic was available for those prioritizing convenience over direct control. The rear-wheel-drive layout is fundamental to the car's balance, transmitting power efficiently to the rear wheels. In terms of physical dimensions, the 2004 Miata measures 156.1 inches in length, 66.5 inches in width, and 48.3 inches in height, sitting on a wheelbase of 86.6 inches. These figures contribute to its exceptional maneuverability and agile handling characteristics.
Chassis, Suspension, and Handling Dynamics
Engineered for precision, the 2004 Miata utilizes an independent double wishbone suspension at both the front and rear axles. This setup, combined with front and rear sway bars, allows the car to hug the road with confidence, minimizing body roll during cornering. The steering system is a rack-and-pinion type, offering tactile feedback that makes the driver feel an integral part of the machine. The overall suspension tuning prioritizes handling over comfort, making it a joy to drive on winding roads.
Brakes, Wheels, and Tires
Stopping power is delivered via ventilated disc brakes at all four corners, a setup that is more than adequate for the car's lightweight construction. The 2004 Miata typically came equipped with 14-inch alloy wheels shod with P205/55R16 all-season tires, providing a balance of grip, comfort, and longevity. These braking and wheel specifications are perfectly matched to the car's dynamics, ensuring controlled deceleration and stable high-speed performance.
Fuel Economy, Dimensions, and Practical Considerations
Efficiency is a strong point for the 2004 model, with the Environmental Protection Agency (EPA) estimating fuel economy at 27 miles per gallon in city driving and 33 miles per gallon on the highway. This is a direct benefit of the lightweight chassis and efficient engine, making it an economical choice for both daily driving and weekend excursions. The trunk space behind the seats offers 5.3 cubic feet, expandable to 15.9 cubic feet with the rear seats folded, providing versatility for light cargo needs.
