The goal is to beat your vehicle’s fuel economy ratings, which you do by eco-driving.

Eco-driving is easy to learn and you may already use some eco-driving tactics. Here are a few examples.

Plan Ahead
Use a traffic app like Waze to avoid congested routes and adjust your travel times when possible.
Reduce Weight
Don’t use your trunk as an extra closet! Additional weight makes your engine work harder.
Minimize Idling
Whenever you idle, your MPG is zero. Avoid long lines at the drive thru by parking and going inside.
Slow Down
Slow down a little! Vehicles differ, but MPG declines sharply for most cars when they go above 65 MPH.

How It Works

The app helps you reduce emissions and save money.

CarPrint works with your car’s OBD port and your mobile device.

Purchase an On-Board Diagnostics (OBD) reader, plug it into your car’s OBD port, pair it with the CarPrint app, and off you go.

The two-inch Bluetooth reader transmits engine data to your phone or tablet, which uploads it to our website where you can see your trip maps and stats.

How You Benefit


Americans drive an average of 280 hours per year – that’s a lot of time in the car.

The CarPrint app takes the boredom out of driving and makes driving interesting.

The objective is to beat your vehicle's fuel economy ratings on as many trips as possible. You know... the city and highway fuel economy ratings that your vehicle manufacturer says are feasible.

How the planet benefits

CarPrint Helps Protect Our Planet One Trip at a Time.

An average passenger car driver adds FIVE TONS of carbon dioxide to the atmosphere each year.

By eco-driving, you can travel just as far on much less fuel. You save money while you help protect the environment.

The more relaxed driving style is good for your heart and your planet.

Volkswagen, Toyota, General Motors. Take your pick. Car companies have been in the news for overstating fuel economy ratings. CarPrint data on real world fuel economy will help us hold car companies accountable.
