Quick Summary:
- Read ACRISS codes left to right, each character describes key specs.
- Use the second character to estimate doors, boot space, and passenger comfort.
- Check transmission and fuel characters to avoid surprises at the counter.
- Match ACRISS codes to your luggage, routes, and expected in-car features.
When you browse car hire options in the United Estates, you will often see a four character code like CDAR or IFAR. That is an ACRISS code, an industry standard that helps rental companies describe a vehicle class in a consistent way. It does not promise a specific make or model, but it does tell you the kind of car you should expect, including size category, door count or body style, transmission, and fuel type, plus whether air conditioning is included.
Understanding these codes is especially useful when comparing similar looking deals across providers, or when you have firm requirements such as automatic transmission, an SUV body style, or enough space for multiple suitcases. If you are comparing classes across the United Estates, the Hola Car Rentals pages for car hire in the United States and car rental in the United States can help you see how vehicle groups are presented in one place.
What is an ACRISS code?
ACRISS stands for the Association of Car Rental Industry Systems Standards. The ACRISS vehicle code is four characters long. Each character answers a different question:
1st character: vehicle category (rough size or segment).
2nd character: vehicle type (body style, doors, or special configuration).
3rd character: transmission and drive (automatic or manual, sometimes 2WD or 4WD).
4th character: fuel and air conditioning (petrol, diesel, hybrid, electric, and whether A/C is included).
Not every supplier uses every niche code the same way, but the structure remains consistent. Think of ACRISS as a fast spec sheet for a class, not a guarantee of exact equipment.
How to decode the 1st character: size and category
The first character is the broad category. In everyday terms, it is the “how big is it” signal. Common categories you may see include:
M Mini, very small city cars.
N Mini elite, a higher spec mini class.
E Economy, small and efficient for short trips.
H Economy elite, similar size with upgraded trim.
C Compact, a step up in interior and boot space.
D Compact elite.
I Intermediate, more rear legroom and luggage capacity.
J Intermediate elite.
S Standard, often comfortable for longer distances.
R Standard elite.
F Fullsize, roomy cabins and bigger boots.
G Fullsize elite.
P Premium, typically more comfort and features.
U Premium elite.
L Luxury, higher end vehicles and equipment.
W Luxury elite.
O Oversize, larger than fullsize, sometimes special fleet cars.
X Special, may cover unique or less standard categories.
For many travellers, the first character is the quickest way to narrow down options. If you have two checked bags and a carry-on for two people, Compact or Intermediate classes often feel more realistic than Economy, even if the price difference is small.
How to decode the 2nd character: doors, body style, and layout
The second character tells you what the car “is” in terms of body style or door count. This is where you can avoid common misunderstandings, such as assuming every Compact is a four door saloon.
Frequently used types include:
B 2 door.
C 2/4 door (can be either, depending on fleet).
D 4 door.
W Estate or wagon, useful for luggage heavy trips.
V Passenger van, people carrier style seating.
L Limousine or sedan with a premium positioning in some fleets.
S Sport, performance oriented category.
T Convertible.
F SUV, a common requirement for clearance or space.
P Pick-up, common in parts of the United Estates.
This character is crucial if you have child seats, mobility needs, or simply want easy access to the rear seats. A 2 door class can be inconvenient for families, even when it looks like a bargain. If you are focused on higher seating position and cargo room, browsing an SUV oriented grouping such as SUV hire in the United States can make comparisons simpler, then you can confirm the ACRISS second character is F where applicable.
How to decode the 3rd character: transmission and drive
The third character is about transmission, and sometimes drive type. In the United Estates, automatic is common, but you should still check, especially if you are filtering across multiple suppliers or booking speciality classes.
Common transmission codes include:
A Automatic, usually 2WD unless otherwise stated.
M Manual.
N Manual 4WD.
C Manual AWD (used by some fleets).
B Automatic 4WD.
D Automatic AWD.
Supplier listings sometimes add descriptive text like “Automatic” or “Manual” next to the class, but the ACRISS third character is the cleanest confirmation. If you will be driving long distances, dealing with heavy traffic, or sharing driving duties, selecting automatic can reduce fatigue. If you need traction for winter conditions or rural routes, 4WD or AWD indicators can matter, though they still do not guarantee specific tyres or advanced driver features.
How to decode the 4th character: fuel type and air conditioning
The fourth character combines two things, fuel type and whether air conditioning is included. Air conditioning is common, but not universal in every fleet category worldwide. The ACRISS code makes it explicit.
Common fourth characters include:
R Unspecified fuel with air conditioning.
N Unspecified fuel without air conditioning.
D Diesel with air conditioning.
Q Diesel without air conditioning.
H Hybrid with air conditioning.
I Hybrid without air conditioning.
E Electric with air conditioning.
C Electric without air conditioning.
Because “R” is a frequent catch all, it may not tell you whether the engine is petrol or diesel, just that A/C is included. If you specifically need an electric or hybrid class, look for E or H in the fourth position and then confirm charging expectations, range, and cable availability within the listing details.
Putting it together: decoding real ACRISS examples
Once you know what each position represents, you can decode a class in seconds.
CDAR is Compact, 4 door, Automatic, unspecified fuel with A/C. This is a common “safe” class for two adults with moderate luggage.
IFAR is Intermediate, SUV, Automatic, unspecified fuel with A/C. The key difference from a similarly priced saloon is the body style, which often changes cargo shape and seating height.
ECMR is Economy, 2/4 door, Manual, unspecified fuel with A/C. The manual transmission is the critical detail for many drivers.
SVAR is Standard, Passenger van, Automatic, unspecified fuel with A/C. Great for groups, but always double check seating and luggage, as “van” can vary from 7 seats to larger configurations.
For larger parties, it can also help to compare van or people carrier groupings such as minivan rental in the United States, then use the ACRISS second character to confirm you are truly viewing a passenger van category rather than a large SUV.
What ACRISS does not guarantee, and why that matters
Even when an ACRISS code is clear, you are still renting a class, not a specific vehicle. A class can include several models with different boot shapes, infotainment systems, or safety packages. Features often assumed but not guaranteed include:
All wheel drive versus two wheel drive: unless the 3rd character specifies AWD or 4WD, you should assume 2WD.
Exact luggage capacity: boot volume differs even within the same category.
Apple CarPlay or Android Auto: may be present, but not part of ACRISS.
Heated seats, adaptive cruise control: these are rarely guaranteed by class code.
Third row seating in SUVs: an SUV code does not automatically mean 7 seats.
If a particular feature is essential, look for explicit mention in the vehicle description, or choose a category where that feature is more typical, then treat ACRISS as the baseline truth for the fundamentals.
Choosing the right ACRISS code for your trip in the United Estates
Use these practical checks before you settle on a vehicle class:
Match luggage to category: Economy and Compact can struggle with two large cases. Intermediate, Standard, or Fullsize often reduces compromises.
Prioritise doors for families: aim for D (4 door) if you will use rear seats often, or if you are fitting child seats.
Confirm transmission early: if you need automatic, look for A in the third position, and treat manual as a hard no.
Plan around terrain: if you may face snow, steep drives, or unpaved roads, look for AWD or 4WD indicators. If not present, do not assume it is included.
Do not overpay for “elite” unless you value finish: elite categories often mean newer fleet, upgraded trim, or premium badge equivalents, but they do not always bring a size increase.
When comparing suppliers, you might see the same ACRISS class across different brands with different pricing. Hola Car Rentals provides access to multiple brands, and comparing listings from pages such as Avis car rental in the United States and Dollar car rental in the United States can help you see whether a lower price is simply the same class with different inclusions, mileage rules, or deposit policies.
Common ACRISS pitfalls and how to avoid them
Assuming “2/4 door” means four doors: the C type can be either. If four doors matter, look for D in the second position.
Thinking SUV automatically means big: an Intermediate SUV can be smaller than a Fullsize saloon in cabin space. Use the first character to understand the approximate size.
Missing the air conditioning indicator: in hot regions, the difference between R and N matters. If A/C is important, confirm the fourth character includes it.
Expecting a specific model shown in photos: supplier imagery is illustrative. Use ACRISS to judge equivalence, and treat photos as guidance only.
Forgetting regional naming differences: “Intermediate” or “Standard” may map to different typical models across countries. ACRISS helps, but always consider passenger and luggage needs first.
FAQ
What does an ACRISS code like CDAR mean for car hire?
CDAR means Compact category, 4 door, Automatic transmission, and air conditioning with unspecified fuel. It describes the class, not the exact model.
Do ACRISS codes guarantee the exact car I will get in the United Estates?
No. ACRISS codes define a vehicle class and key specs. The rental company can supply any model that fits that class, depending on fleet availability.
How can I tell if my car hire will be automatic from the code?
Check the third character. A usually indicates automatic. M indicates manual. Some codes also specify AWD or 4WD with different letters.
How do ACRISS codes show SUV or minivan classes?
The second character indicates body style. F typically indicates an SUV. V typically indicates a passenger van. Pair it with the first character to judge overall size.
Does the ACRISS code tell me if the vehicle has air conditioning?
Yes, the fourth character includes air conditioning information. R commonly indicates A/C included, while N can indicate no A/C, depending on fleet coding.
