Why Upgrade

Data CarQueryAPI never had

Built for apps that need more than just a year/make/model dropdown.

Towing Capacity
Max towing by year, make, model and trim. 4,072 vehicles covered. Essential for fleet, trailer, and RV apps.
New in 411
Oil Capacity + Viscosity
33,931 records with exact quart count, oil type (synthetic/conventional) and viscosity. Built for shop management and maintenance apps.
New in 411
Tire Sizes + Bolt Patterns
6,237 tire records and 4,714 bolt pattern records by year/make/model. Everything a wheel and tire app needs.
New in 411
Horsepower Data
16,269 records covering HP, torque, engine displacement and drivetrain by year and trim level.
New in 411
Always Online
Hosted on Cloudflare's global edge network. Sub-200ms worldwide. No more "account suspended" surprises.
2026 Data
CarQueryAPI stopped updating in 2019. Every 411 dataset covers through 2026 - 7 years of vehicles you were missing.
