Italian Car VIN Options Guide: Fiat and Alfa Romeo Terms
Fiat and Alfa Romeo equipment records use names that don't explain themselves: MultiAir, Q4, DNA, Ti, Lusso, Veloce, Quadrifoglio, Abarth, Trekking. Most are Italian words or long-running brand labels for trims, engines, and drivetrain systems. To find out which of them apply to a particular car, enter its 17-character VIN in the VIN lookup. You'll see the car's basic identity from the public VIN decoder and, when a record is available, its factory build sheet, with each installed item listed by sales code and description. The glossary that follows helps you read those lines. Names and contents shift by model year and market, so treat a trim name as a starting point and the car's own record as the answer.
Trim and version names
| Term | Where you'll see it | What it means |
|---|---|---|
| Pop, Sport, Lounge | Fiat 500; the same names also appear on the 500X in some years | Fiat trim names. Pop is the entry level, Sport leans toward sportier styling, and Lounge toward comfort and convenience. |
| Abarth | Fiat 500, 124 Spider | Fiat's performance label, named for the tuning company Carlo Abarth founded. On the 500 it brings a turbocharged engine; on both models it adds firmer chassis tuning and its own styling. |
| 500c | Fiat 500 | The cabriolet version, with a power fabric roof that slides back while the side pillars and door frames stay in place. |
| Trekking | Fiat 500X | A trim with more rugged, off-road-inspired styling. |
| Classica, Lusso | Fiat 124 Spider | Trim names. Lusso is Italian for luxury, and the Lusso trim adds comfort and upscale features over the Classica. |
| Sprint, Ti | Alfa Romeo Giulia, Stelvio, Tonale | Sprint is an entry trim name used in recent model years. Ti, historically short for Turismo Internazionale, sits above it with more comfort and convenience equipment. |
| Veloce | Alfa Romeo Giulia, Stelvio, Tonale | Italian for fast. A sport-oriented trim with its own styling and, depending on model and year, performance-focused equipment. |
| Quadrifoglio | Alfa Romeo Giulia, Stelvio | Italian for four-leaf clover, Alfa Romeo's long-standing performance emblem. Quadrifoglio versions use a twin-turbocharged 2.9-liter V6. |
Engine and drivetrain terms
- MultiAir. Fiat's electro-hydraulic system for controlling the intake valves, which varies valve lift and timing. It appears on the 1.4-liter engines in the North American Fiat 500 and 124 Spider and on the 2.4-liter four offered in the 500X. MultiAir Turbo adds a turbocharger.
- Turbo and twin-turbo. Four-cylinder Giulia and Stelvio models use a turbocharged 2.0-liter engine; the Quadrifoglio's V6 uses two turbochargers.
- Q4. Alfa Romeo's all-wheel-drive system on the Giulia and Stelvio. It runs mostly as rear-wheel drive and sends torque to the front axle when needed. On the build sheet, look for the drivetrain line rather than trusting a badge.
- DNA. Alfa Romeo's drive-mode selector: Dynamic, Natural, and Advanced Efficiency. Quadrifoglio models add a Race mode. Because the selector is standard, it says little about a car's options on its own.
- Plug-in hybrid. The Tonale arrived in North America as a plug-in hybrid, pairing a turbocharged gasoline engine with electric drive. For the 2026 model year the U.S. Tonale switched to a turbocharged gasoline engine without the plug-in system, so check the powertrain line rather than assuming every Tonale plugs in.
Build sheet vocabulary
- Sales code. A short alphanumeric code for one item, package, or production instruction. The description beside it is what matters to a reader; the code is how the factory tracks the item.
- Package or group. A bundle ordered as one line that adds several features at once. On Alfa Romeo models especially, packages often explain the gap between two cars of the same trim.
- Standalone option. A single item ordered on its own, such as a paint color, wheel design, or sunroof.
- Paint entries. In the site's sales code navigator, paint colors often carry codes starting with P, such as PWL, listed as Brilliant White. Related entries handle how paint was ordered or applied, like 6CV, listed as Two Tone Paint Tracking.
- Delete. A line that removes something normally included. The navigator, whose list spans Stellantis brands rather than Fiat and Alfa Romeo alone, includes KT8, for example, as Delete Ram Badge.
- Tracking and order codes. Production and ordering entries rather than equipment, such as 58E, listed as Manual transmission Tracking. They don't add anything to the car.
The sales codes explainer covers how codes and descriptions fit together in more depth.
How to look up a specific car's equipment
- Copy the VIN from the windshield plate, the driver's door jamb label, or the registration.
- Enter all 17 characters in the lookup. The letters I, O, and Q never appear in a VIN, so a character that looks like an O is a zero.
- Confirm the identity fields. Make, model, and model year should match the car in front of you.
- Read the build sheet in groups: powertrain first, then paint and interior, then packages, then individual options.
- Match unfamiliar lines against the terms above or the sales code navigator, and set aside administrative or tracking entries.
- Compare the record with the car. Missing or extra equipment may mean later changes; wheels, audio, and badges are frequently swapped.
If no build sheet comes back, common reasons include a mistyped VIN, a car built for another market, or an older model; availability differs from one VIN to the next. For the most option-heavy models, see the Quadrifoglio options and Fiat 500 options pages.
