⚙️ Engine Specifications

Engine Family:

Likely based on Fiat's Lampredi or Pratola Serra engine families, common in Fiat models of that era. Specific displacement and configuration would depend on the Mirafiori variant.

Engine Configuration:

Could be inline-4 or V6 depending on the specific Mirafiori model. The 'Mirafiori' name was historically associated with larger sedans and coupes.

Fuel Type:

Gasoline (Petrol)

Stock Horsepower:

Variable based on specific engine (e.g., 1.6L, 1.8L, 2.0L, or V6). Ranges typically from 90-130 HP for 4-cyl and 150-200+ HP for V6.

Stock Torque:

Variable. Approximately 130-180 Nm for 4-cyl and 180-250+ Nm for V6.

Fuel Delivery:

Fuel Injection (likely multi-point or sequential)

Ignition System:

Electronic Ignition (Distributorless or Coil-on-Plug)

🔧 Transmission

Type:

Likely a 5-speed Manual Transmission

Type:

Optional 4-speed Automatic Transmission

Drive Layout:

Rear-Wheel Drive (RWD)

📐 Dimensions

Body Styles:

Historically, the Mirafiori name was applied to Fiat sedans, coupes, and estates. The 2004 context implies a later iteration or a specific market interpretation, possibly related to Fiat's larger RWD sedans.

Wheelbase:

Varies significantly by specific model, but typically in the 2500-2700mm range for Fiat sedans of that era.

Wheel Bolt Pattern:

Commonly 4x98 or 5x100 for Fiat vehicles of this period, depending on the model and era.

🛡️ Safety Features

Crash Test Results:

Specific ratings for a 2004 Fiat Mirafiori are not widely documented under this exact name for major global markets. Fiat's safety standards in the early 2000s were evolving.

ABS:

Available, often as an option or standard on higher trims.

Airbags:

Front airbags typically standard, side airbags may have been optional.

💡 Technology Features

Audio System:

Basic AM/FM radio with CD player likely standard. Cassette player on earlier models. Upgrades common.

Climate Control:

Manual or automatic climate control depending on trim level.

Cruise Control:

Optional on many trims.

Connectivity Options:

Limited by era. Likely no advanced Bluetooth or USB connectivity on base models. Aftermarket head units common.

🔧 Maintenance

Oil Change Interval:

Typically 10,000-15,000 km or 12 months, depending on oil type and driving conditions. After modifications, monitoring oil condition is crucial.

Spark Plug Replacement:

Around 60,000-100,000 km, depending on spark plug type (e.g., standard, platinum, iridium). Performance modifications may necessitate more frequent checks.

Engine Oil:

Likely SAE 10W-40 or 5W-40, API SJ/SL or ACEA A2/A3. Always consult the specific vehicle's owner's manual or Fiat specifications for the correct grade and specification.

Coolant:

Ethylene glycol based coolant, typically with a pink or blue additive. Fiat specifications should be consulted for correct type and mixture ratio.

Transmission Fluid Manual:

GL-4 or GL-5 rated gear oil, viscosity typically 75W-90 or 80W-90.

Transmission Fluid Automatic:

Dexron III or equivalent automatic transmission fluid (ATF).

Common Failures:

Potential issues on older Fiats can include electrical gremlins, rust in certain body areas, aging rubber components (hoses, seals), and occasional ignition or fuel system component failures. Modifications can exacerbate these if not performed correctly.

Modification Impacts:

Increased strain on engine internals, potential for detonation with incorrect tuning, exhaust leaks, and increased emissions if catalytic converters are compromised.

📚 Vehicle History

Fiat History:

Fiat, founded in 1899, is one of Italy's oldest and largest automobile manufacturers, known for its innovation and popular compact cars, as well as larger sedans and performance models throughout its history.

Mirafiori Legacy:

The Fiat Mirafiori nameplate was originally introduced in 1974 for a large family sedan and later used for a range of sedans, coupes, and estates produced until the early 1980s. The 2004 designation in the product name suggests either a retrospective naming convention for a vehicle that shares its spirit or a specific aftermarket interpretation, as Fiat had moved to different naming conventions by 2004.

Manufacturing Location:

Fiat vehicles are primarily manufactured in Italy, but also in other countries through joint ventures and subsidiaries.

🏆 Awards & Recognition

Historical Accolades:

While the original Mirafiori model received positive reviews for its comfort and space in its era, specific awards for a 2004 variant are not applicable as Fiat had moved to different model lines by then. Fiat vehicles in general have received numerous 'Car of the Year' awards across various models over the decades.
