How to Check Vehicle Safety and Fuel Economy with Claude
Check Vehicle Safety and Fuel Economy with Claude and ToolRouter. Compare safety ratings, fuel economy, and recall status across vehicles before buying.
Tool
Use Claude with Vehicle Data to compare safety ratings and fuel economy across vehicles and get an interpreted assessment. Claude can explain what a 4-star versus 5-star safety rating means in practical terms, calculate annual fuel cost differences at your mileage, and flag whether any recall affects a critical safety system.

Steps
Once connected (see setup above), use the Vehicle Data tool:
- Name the vehicles you want to compare and your annual mileage if relevant.
- Ask Claude to run `safety_ratings`, `fuel_economy`, and `check_recalls` via `vehicle-data` for each vehicle.
- Ask Claude to compare the results side by side and explain the practical significance of any differences.
- Ask Claude to give a clear recommendation based on your priorities — safety, running cost, or both.
Example Prompt
Try this with Claude using the Vehicle Data tool
Use vehicle-data to compare safety ratings, fuel economy, and recall history for: (1) 2022 Toyota Corolla and (2) 2022 Honda Civic. I drive about 12,000 miles per year. Run safety_ratings, fuel_economy, and check_recalls for each. Tell me which is safer, which is cheaper to run, whether either has outstanding recalls, and which I should buy if my priority is safety.
Tips
- Provide your annual mileage so Claude can calculate annual fuel cost differences, not just MPG figures.
- Ask Claude to explain what a recall covers specifically — a recall for a seat adjustment motor is very different from a brake system recall.
- Ask for a clear recommendation rather than just a comparison — it forces Claude to weigh the trade-offs explicitly.
