The "fixed" math on FastestLaps is excellent. The site provides a theoretical Power-to-Weight ratio (hp/t). When comparing two cars, it fixes the math for you:
The fastestlaps compare cars fixed methodology requires discipline. You cannot simply add two cars to the box and look at the first number.
Your action plan:
By following these four rules, you turn FastestLaps from a confusing archive of random numbers into the most powerful automotive benchmark tool on the web. So go ahead—fix your variables, compare your cars, and find out which machine truly rules the tarmac.

FastestLaps "Compare Cars" tool has been updated and is fully functional on their Create Comparison Key Features of the Comparison Tool: Side-by-Side Analysis : You can now compare up to 4 vehicles simultaneously, including road-legal cars and motorcycles. Performance Scoring
: The tool automatically calculates winners based on a weighted sum of track lap times and straight-line performance data (acceleration and top speed). Timeline Views : Users can toggle between standard comparisons and a Timeline view
to see how performance has evolved between different model generations. Detailed Specs fastestlaps compare cars fixed
: The comparison includes metrics such as lateral acceleration (skidpad), braking performance, and power-to-weight ratios. Troubleshooting Common Issues:
If you previously experienced issues with the "Compare" feature, ensure the following to avoid errors: Select Specific Trims
: Ensure you have selected a specific variant (e.g., "Model Y Performance" vs. "Model Y Long Range") as the tool requires precise model data to generate a side-by-side. Check Data Availability
: Comparisons only work for vehicles already in the database. You can browse the latest additions, such as the Chevrolet ZR1X Toyota Supra Final Edition , to ensure they are live. between two particular models? Compare cars - FastestLaps.com
One of the most interesting elements of tracking this data is spotting the "Ring Taxis"—cars that seem to defy their weight. When you compare a modern electric sedan (like a Tesla Model S Plaid) against a traditional supercar, the data divergence is shocking. The EV annihilates the acceleration benchmarks (0-100 km/h, 0-200 km/h) but often falls apart in the "Fixed Track" comparison on longer, twistier circuits due to braking fade and weight inertia.
FastestLaps exposes the manufacturer's hand. If a car is incredibly fast on the autobahn but sluggish at Tsukuba, the site reveals that the manufacturer prioritized high-speed stability over agility.
Let’s run a quick comparison using the tool. The "fixed" math on FastestLaps is excellent
At first glance, the Honda wins by 2.5 seconds. But look deeper in the compare view. On a shorter track like Willow Springs:
That’s over a second on a short lap. The Compare tool immediately shows you where the Honda gains time (corner entry grip) and where the Golf fights back (wet conditions or standing start acceleration).
Now that the page is fixed, here is the correct workflow to get actionable data.
Step 1: Navigate to the Database Go to the "Lap Times" or "Cars" tab. Do not use the global search for comparison; it often breaks the referrer link.
Step 2: Select Your First Car Click on the car’s name. On its individual profile page, look for the green button labeled "Compare this car".
Step 3: Add the Rival You will be taken to a secondary menu. Use the filter (Brand, Drivetrain, Year) to find the second car. Click "Select".
Step 4: The "Fixed" Setting
Once both cars load, immediately check the URL. It should look like:
fastestlaps.com/comparisons/[car_a]-vs-[car_b] By following these four rules, you turn FastestLaps
If the layout is broken, append ?layout=fixed to the end of the URL manually and press Enter. This hardcodes the layout.
Before diving into the "fixed" methodology, let’s address the elephant in the room: Variability.
When you look at a manufacturer’s claimed Nürburgring time, it is usually set by a professional driver on a closed track, on brand-new tires, with optimal weather, and often in a pre-production car with extra aero bits.
If you try to compare a Porsche 911 GT3’s time from Sport Auto magazine (which uses a partial "bridge to gantry" section) with a Lamborghini Aventador’s time from a YouTube influencer (who might be using a different tire compound), you are comparing apples to oranges.
This is why the user query for fastestlaps compare cars fixed has emerged. Users want the site to fix the variables:
The most common "fixed" comparison on forums involves ignoring raw horsepower and fixing the analysis to Power-to-Weight Ratio (lb/hp). FastestLaps calculates this automatically. By fixing this variable, you can predict which car will be faster on a straight line regardless of manufacturer claims.
Once you have the "fixed" view working, you can manipulate the data.
