A lap time set at 10°C (ideal for turbo cars) is not equal to a lap at 35°C (ideal for cooling). FastestLaps rarely stores this metadata.
Lap times don’t measure smiles per hour. A slow Miata might be more fun than a fast Nissan GT-R. So use the tool to settle bets about speed, but never forget: the best car isn't always the one with the lowest number.

Step 1: Navigate to the "Compare cars" page.
You’ll find it in the top navigation menu under "Rankings" or directly via fastestlaps.com/compare. fastestlaps compare cars fixed
Step 2: Select your first car. Start typing. The search is smart. “M4 CSL” will pop up instantly.
Step 3: Add your rival. Click "Add car" and search for the competitor. Want chaos? Compare a Porsche 911 GT3 RS against a Tesla Model S Plaid.
Step 4: Look at the "Shared Tracks" table. This is the magic section. Ignore the individual best times. Scroll down to Circuits where both cars have run. Here you will see:
Step 5: Filter by "Same driver" (if available). The holy grail. When a pro driver (like Randy Pobst or Sport Auto) pilots both cars back-to-back, that’s the closest thing to a laboratory test you will ever get. A lap time set at 10°C (ideal for
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.
The primary appeal of FastestLaps is its ability to strip away the marketing fluff. When you pull up a comparison, you are met with hard data: lap times.
The beauty of the platform lies in its aggregation. It compiles times from major automotive publications (Sport Auto, MotorTrend, Car and Driver), manufacturer claims, and independent user-submitted sessions. This allows you to cross-reference. If Car A ran a 7:40 at the Nürburgring with a pro driver, but Car B ran a 7:45 with a journalist, the comparison tool allows you to contextualize that gap. It creates a fixed reference point: the track doesn't lie. Ready to settle a score
If you want the most "fixed" comparison possible, you must look at the Simulated Laptimes section on FastestLaps.
For newer cars that haven't been tested back-to-back, FastestLaps allows simulation data (usually via Assetto Corsa or rFactor physics mods).
If you see a note that says "Simulated time – Buttonwillow" and two cars are listed side-by-side, you are looking at the purest "fixed" mathematical comparison available on the internet today.
Most comparison sites show you two cars side-by-side, but they mix lap times from different years, different weather conditions, and different drivers. That’s useless.
FastestLaps solves this by focusing on shared track data. When you compare two cars, the system prioritizes lap times where both vehicles lapped the same circuit, ideally on a similar date.
For example:
