Decoding the acronym soup: OEM, SAAR, ASP, and beyond
# Decoding the acronym soup: OEM, SAAR, ASP, and beyond
An analyst opens a Ford earnings call transcript. Within the first two minutes she hits "SAAR", "ASP", "BEV mix", and "ADAS take rate". If those four terms slow you down, you read automotive documents at half speed. This lesson fixes that. Master roughly 30 acronyms and a handful of routine calculations, and you will parse any earnings call, analyst note, or supplier deck without flinching.
The players: who makes what
OEM (original equipment manufacturer)
The company whose badge is on the car: Toyota, Volkswagen, General Motors, Stellantis. Confusingly, "OEM" is also used by suppliers to mean "the automaker I sell to." Context tells you which.
Tier 1, tier 2, tier 3 suppliers
The supply chain in layers. A Tier 1 sells finished systems directly to the OEM (Bosch sells braking systems, Continental sells tires and electronics). A Tier 2 sells components to the Tier 1. A Tier 3 sells raw materials or basic parts. Bosch, Denso, ZF, Magna, and Continental are the giant Tier 1s.
The balance of power
In 2025 the largest OEM groups by global volume were Toyota, Volkswagen Group, and Hyundai-Kia, each in the range of roughly 8 to 11 million vehicles per year (estimates). In China, BYD became the dominant domestic force and a serious global exporter. Tesla remains the BEV benchmark but sells far fewer total units than the legacy giants.
The market size numbers
You need two reference points cold.
SAAR (seasonally adjusted annual rate)
The single most quoted demand figure. Take one month of vehicle sales, strip out seasonal noise (December and summer distortions), and project it to a full-year pace. If dealers sold a February volume that annualizes to 16 million, the SAAR is "16 million."
US SAAR: roughly 15 to 16 million light vehicles per year (2024 to 2025 estimates). A SAAR above 17M signals a hot market; below 14M signals trouble.
Europe (EU + EFTA + UK): roughly 13 million new passenger car registrations per year (2024 to 2025 estimates), still below the pre-2020 peak near 15M.
US figures usually mean light vehicles: passenger cars plus light trucks (which includes most SUVs and pickups). Heavy trucks are counted separately. In the US, light trucks and SUVs now dominate sales, roughly 80% of the mix (estimate).
The money numbers
MSRP (manufacturer's suggested retail price)
The sticker price the OEM recommends. The dealer can sell above or below it.
ASP (average selling price)
The actual average price customers pay across all units. This is the number that moves earnings. US new-vehicle ASP has hovered around 47,000 to 48,000 USD (2024 to 2025 estimates), up sharply from pre-2020 levels near 35,000 USD.
Incentives
Cash the OEM or dealer puts back on the hood to move metal: rebates, cheap financing, lease deals. Rising incentives usually signal softening demand. Analysts watch "incentive spend per vehicle" closely.
Worked calculation: ASP net of incentives
An OEM reports MSRP of 45,000 USD and average incentives of 3,000 USD per vehicle. Transaction ASP is:
Net ASP = 45,000 - 3,000 = 42,000 USD per vehicle
Revenue on 100,000 units = 42,000 x 100,000 = 4.2 billion USD
Raise incentives to 5,000 USD and revenue drops to 4.0 billion USD on the same volume. That 2,000 USD swing is why incentive discipline dominates earnings calls.
Powertrain acronyms
This is where non-technical readers get lost. Learn these five.
ICE (Internal Combustion Engine): traditional gasoline or diesel engine.
BEV (Battery Electric Vehicle): battery only, no engine. Tesla Model 3, VW ID.4.
PHEV (Plug-in Hybrid Electric Vehicle): battery you can plug in, plus an engine backup.
HEV (Hybrid Electric Vehicle): self-charging hybrid, no plug. The classic Toyota Prius.
FCEV (Fuel Cell Electric Vehicle): runs on hydrogen. Niche, small volumes.
"EV" loosely means any plugged vehicle, but precise notes distinguish BEV from PHEV. "xEV" is shorthand for all electrified types combined.
BEV mix and take rate
BEV mix is the share of a company's sales that are battery electric. Take rate is the share of buyers who choose a given option (a BEV variant, or an ADAS package). In Europe, BEVs were roughly 14 to 16% of new car registrations in 2024 to 2025 (estimate). In the US, BEV share was lower, roughly 8 to 10% (estimate). China ran far ahead of both.

Technology and safety acronyms
ADAS (Advanced Driver Assistance Systems): automated safety and convenience features (automatic emergency braking, lane keeping, adaptive cruise control). A major revenue and margin lever, sold as software and hardware packages.
AD / AV (Autonomous Driving / Autonomous Vehicle): full self-driving. Still limited to robotaxi pilots (Waymo).
SDV (Software-Defined Vehicle): a car whose features are controlled by software and updated OTA (Over-The-Air), like a smartphone. The strategic buzzword of the decade.
BOM (Bill of Materials): the full parts list and cost to build one vehicle. Battery cost dominates a BEV's BOM.
Manufacturing and operations acronyms
JIT (Just-In-Time): parts arrive at the line exactly when needed, minimizing inventory. Efficient but fragile, as the 2021 to 2022 chip shortage exposed.
CKD / SKD (Completely / Semi Knocked Down): vehicles shipped as kits and assembled locally, often to dodge import tariffs.
Days of supply / DSI: how many days of sales the dealer inventory would cover at the current pace. Around 60 days is considered healthy in the US. Well above signals a glut; well below signals shortage.
Capacity utilization: how full the factories run. Below roughly 80% and fixed costs crush margins.
Worked calculation: days of supply
A brand has 90,000 vehicles in dealer inventory and sells 1,500 per day.
Days of supply = 90,000 / 1,500 = 60 days
Sales slow to 1,000 per day and days of supply jumps to 90. Expect incentives to rise next quarter.
Knowledge check
1. An analyst reads a supplier deck where the company describes selling finished braking systems directly to Toyota and refers to Toyota as its 'OEM.' What is the most accurate interpretation of this usage?
2. Why is SAAR preferred over simply reporting one month's raw vehicle sales when assessing demand?
3. A company sells electronic control chips to Bosch, which integrates them into a braking system sold to General Motors. How is the chip company best classified?

Regulation acronyms you will actually see
Regulation drives product strategy, so these appear constantly.
CO2 targets (EU): the European Union sets binding fleet-average CO2 emission limits per manufacturer, enforced by the European Commission. Miss them and you pay per-gram fines. These rules are the main engine pushing European BEV volume.
CAFE (Corporate Average Fuel Economy): the US fuel-economy standard, administered by NHTSA (National Highway Traffic Safety Administration).
EPA (Environmental Protection Agency): sets US tailpipe emissions and the range labels you see on EV window stickers.
Euro 7: the EU's latest pollutant emission standard for new vehicles, tightening limits on tailpipe and brake/tire particulates.
NCAP (New Car Assessment Program): independent crash-test ratings. Euro NCAP in Europe drives which safety features become standard.
The US EPA fuel economy site is a free, reliable place to check any US model's official range and efficiency.
Financial and reporting acronyms
Kept strictly to sector usage.
Volume: units sold or produced. The starting point of every model.
Mix: the blend of what sold. A shift toward pickups and BEVs is "favorable mix" if those carry higher ASP.
Content per vehicle: for suppliers, the dollar value of parts they put in each car. Growing content per vehicle (more electronics, more ADAS) is the supplier growth story.
Warranty reserve / recall: money set aside for future repairs. Spiking warranty costs are a quality red flag.
Practical due diligence checks
When you evaluate any automotive company or claim, run these fast checks.
1. Volume vs. mix vs. price. If revenue rose, decompose it. Was it more units, richer mix, or just price hikes? Price-driven growth in a softening market is fragile.
2. Incentives trend. Rising incentives plus rising inventory equals demand weakness, no matter what the headline ASP says.
3. Days of supply by brand. Above 90 days signals coming discounts.
4. BEV mix vs. regulatory need. In Europe, check whether a company's BEV mix is high enough to meet CO2 targets and avoid fines.
5. Supplier content exposure. For a Tier 1, ask which powertrain its content leans toward. Heavy ICE-only content is a declining book.
6. Warranty and recall trend. A sudden jump often precedes a profit warning.
Key Takeaways
SAAR is the demand pulse. Anchor on roughly 15 to 16M US light vehicles and roughly 13M European car registrations per year (2024 to 2025 estimates).
ASP net of incentives, not MSRP, drives revenue. A 2,000 USD incentive swing on 100,000 units moves 200 million USD.
Learn the five powertrain acronyms cold: ICE, BEV, PHEV, HEV, FCEV, and always distinguish BEV from PHEV in "BEV mix."
Days of supply near 60 is healthy. Rising inventory plus rising incentives is the classic demand-softening signal.
Regulation (EU CO2 targets, US CAFE) sets product strategy. Check whether a company's BEV mix meets its regulatory obligations before trusting its margin story.
