Common Meanings of AFE in Automotive
- Average Fuel Economy – a driver-facing metric showing fuel efficiency.
- Advanced Flow Engineering (aFe) – a well-known aftermarket performance parts brand.
- Authorization for Expenditure – an accounting/finance term used in dealership, fleet, or OEM project management.
- (Less common, but occasionally seen) Automatic Front End – shorthand in some older technical or diagnostic documents, though rare today.
Contextual Explanation
1. Average Fuel Economy
- Where it applies: This is the most common meaning in modern cars. It shows up on dashboards or infotainment displays, typically calculated in miles per gallon (MPG) or liters per 100 kilometers (L/100 km).
- Why it matters: Helps drivers monitor fuel efficiency over a trip or lifetime, encouraging economical driving. OEMs include it as part of trip computers and energy management systems.
2. Advanced Flow Engineering (aFe)
- Where it applies: Not an engineering acronym, but a brand name. aFe Power is a major aftermarket manufacturer specializing in cold air intakes, performance filters, exhaust systems, and tuners.
- Why it matters: Car enthusiasts, tuners, and performance shops use “aFe” as shorthand when referencing the company’s products, which are popular for boosting horsepower, torque, and intake sound.
3. Authorization for Expenditure
- Where it applies: Internal documentation at OEMs, dealerships, and fleet management companies. An AFE form is often required before approving a repair program, capital purchase, or major warranty action.
- Why it matters: It’s an administrative tool, not something a driver will see on a dashboard. But if you’re in dealership management or corporate fleet service, you’ll run into it.
4. Automatic Front End (rare/dated usage)
- Where it applies: Sometimes appears in legacy service documentation or shorthand for automatic front-end alignment/test equipment.
- Why it matters: Mostly historical; unlikely to confuse modern drivers but worth noting for technicians reviewing older manuals.
Example Use Cases
- Dashboard/Trip Computer: A driver presses the “INFO” or “CAR” button and sees “AFE: 27.5 MPG” displayed, showing their running average fuel economy.
- Aftermarket Catalog: An enthusiast browsing a tuner website might see “aFe Momentum GT Cold Air Intake System” listed as an upgrade option.
- Dealership Paperwork: A service manager fills out an “AFE Request” form to approve funding for a major tool purchase.
- Older Technical Manuals: A 1980s alignment machine might reference “AFE calibration,” though this is not common anymore.
Summary Takeaway
In cars, AFE most often means “Average Fuel Economy” on your dashboard, but it can also refer to the aftermarket performance brand aFe Power, or an accounting term (“Authorization for Expenditure”) in dealership/fleet settings. For everyday drivers, if you see “AFE” on your dash, think fuel efficiency.
