The most efficient way to get detailed car specs is to use a combination of online resources. Start with third-party automotive websites like Edmunds or Kelly Blue Book (KBB), which provide standardized, easily comparable data. For the most definitive information, cross-reference this with the official manufacturer's website for the specific model you're researching. For used cars, a vehicle identification number (VIN) decoder is essential for getting the exact equipment a car left the factory with.
When reviewing specs, focus on key metrics that directly impact your driving experience. Horsepower and torque determine acceleration and towing capability, while EPA-estimated MPG (miles per gallon) figures are critical for calculating long-term fuel costs. For electric vehicles (EVs), the driving range and charging time are the most important specifications. Cargo space, often measured in cubic feet, and safety ratings from the Insurance Institute for Highway Safety (IIHS) are also vital for practical decision-making.
Here is a comparison of key specs for three popular 2024 midsize SUVs to illustrate the data you should look for:
| Specification | 2024 Honda CR-V EX | 2024 Toyota RAV4 XLE | 2024 Ford Escape ST-Line |
|---|---|---|---|
| Engine | 1.5L Turbocharged 4-cylinder | 2.5L 4-cylinder | 1.5L Turbocharged 3-cylinder |
| Horsepower | 190 hp | 203 hp | 181 hp |
| Torque | 179 lb-ft | 184 lb-ft | 190 lb-ft |
| EPA Combined MPG | 31 MPG | 30 MPG | 31 MPG |
| Cargo Volume (behind 2nd row) | 39.3 cubic feet | 37.5 cubic feet | 37.5 cubic feet |
| IIHS Top Safety Pick | Yes | Yes | No |
Don't just rely on numbers. Seek out professional reviews that explain how these specs translate to real-world driving, such as how a car's chassis tuning (the setup of its suspension and frame) affects ride comfort. Owner forums can also provide long-term reliability insights you won't find in a spec sheet.

I always go straight to the carmaker's website. It's the source of truth for what's available right now. You can use the "build and price" tool to pick a trim level and add options; the site updates the specs and price instantly. It's perfect for seeing what features come standard and what costs extra. After that, I check Edmunds to see how those specs stack up against competitors. It gives you the full picture.

If you're looking at a used car, the spec sheet from the model year might not be enough. You need the VIN. That number is the car's fingerprint. Plug it into a free VIN decoder online, and it will tell you the exact factory-installed equipment for that specific vehicle. This is the only way to be 100% sure about the engine size, transmission, and optional features the car actually has, preventing any surprises after you buy it.

Honestly, the best specs come from people who already own the car. I spend hours on forums and Reddit. You'll find owners talking about their real-world gas mileage, which is often different from the official EPA number. They'll tell you if the cargo space is actually usable or if the back seat is comfortable for a long trip. It’s unvarnished, practical info that the official brochures won’t give you. The numbers are important, but the everyday experience is what really matters.

For a quick, side-by-side comparison, automotive media sites are unbeatable. Platforms like Motor Trend or Car and Driver conduct instrumented testing, providing data like 0-60 mph acceleration times that are often more realistic than manufacturer claims. They also test real-world highway fuel economy. Their reviews contextualize the specs, explaining if a car with slightly less horsepower feels quicker due to better transmission tuning. This approach combines hard data with expert analysis to help you understand the performance you can actually expect.
