Understanding how sales shift between brands, body types, and regions is critical for anyone watching the U.S. auto industry. The U.S. Automotive New Vehicle Sales and Market Share Dashboard makes it simple to track these changes month-over-month, providing a clear view of which brands are gaining ground, which are losing share, and where sales momentum is building.

This free, interactive dashboard is powered by the Foureyes inventory dataset, which collects VIN-level merchandising data from over 20,000 U.S. franchise dealership websites daily. By tracking when vehicles appear and leave dealership websites, then resolving for dealership trades, we can reliably estimate monthly sales and calculate market share across brands.

Whether you’re a dealer benchmarking your dealership against competitors, an OEM analyzing regional shifts in demand, or an analyst tracking how body types perform over time, this dashboard gives you the timely, high-level insights you need in one place.

In this article, we’ll walk through each section of the dashboard, define the terms used in the dashboard, and answer some frequently asked questions. If you have additional questions, you can always contact us.

Monthly New Auto Sales

At the top of the dashboard, you’ll find the Monthly New Auto Sales chart. This view highlights how many new vehicles were sold each month over the past 12 months.

If you want to know more details on a given month, hover over that month’s dot on the line. It will show the daily sales curve for that month.

If you want to explore one or more specific brands, you have two options. First, you can use the brand filter directly below the chart to dynamically adjust the data:

• To select one make, simply click the name.
• To select multiple, specific brands, hold down Ctrl (Windows) or Command (Mac) while clicking.

Or two, you can use the Brand and Body Type Filters. In the brand box, click the arrow to see all the brands in a drop-down list. Unselect any brands you want to exclude, or unclick “All” and then select only the brands you want. Be sure to click “Apply” when you are done so your selections are applied.

Follow this same process if you want to see the data by Type (e.g., car, SUV, truck, van), or by Brand and Type.

Your selections here filter all the way down the page, including the Market Share, Median Daily New Inventory, and State-level sections. This is so you can keep analysis consistent across the full dashboard. To look at the full dataset again, simply refresh the page, or use the “Reset View” button at the bottom of the dashboard.

By filtering by brand or type, you’re better able to spot sales momentum. For example, you can see which brands are climbing in sales volume after new model releases or incentive campaigns, and which are trending down month to month.

Market Share of Sales by Brand

Beneath the sales trendline, the Market Share of Sales by Brand chart shows how sales are distributed across manufacturers. Each color band represents a brand’s share of total sales for the month.

Market share offers a direct lens into competitiveness. If a brand’s share grows steadily, it may reflect strong supply, attractive incentives, or rising consumer preference. Shrinking share, meanwhile, can signal challenges with inventory, pricing, or marketing effectiveness.

If you’d like more information on a specific brand, hover over its colored bar to see its market share percentages for the year.

Remember, the above filters allow you to narrow your view by both brand and body type. For instance, if you’re interested to see if the market share for trucks is changing, select “Truck.” The view will change to only show brands selling trucks, and clicking deeper shows the details of that trend for trucks within the brand.

State-by-State Sales and Inventory Changes

The lower half of the dashboard brings in regional insights through side-by-side state maps:

• New Auto Sales by State: Shows which states saw sales growth or decline compared to the selected time period.
• Inventory Levels by State: Tracks how supply changed across regions, helping you understand if shifts in sales are tied to availability.
• Percent Change Summaries: Quick reference boxes summarize total U.S. sales and inventory changes so you can see the national picture at a glance.

Hovering over any state will provide you with details by brand. Clicking on any state will filter the rest of the dashboard to that geography. If you’re interested in a specific region, select multiple states using Ctrl + click to easily compare specific regions to the national trend. This will also update the percent change reference boxes.

Toolbar and Usability Features

It's easy to miss a small white toolbar running along the bottom of the dashboard, but with it you can:

• Undo or redo actions
• Reset the view
• Refresh data
• Pause or replay animations
• Download charts (Image, PDF, PowerPoint)
• Enter full screen

Frequently Asked Questions

Q: How does this dashboard compare to OEM or government sales reports?

A: While OEM and government reports provide official figures, they are often published with significant delay. This dashboard gives a near real-time perspective using a consistent methodology applied across all brands.

Q: Why track market share monthly instead of quarterly?

A: One of the advantages of Foureyes data is that it is more timely than traditional quarterly or annual reports. By reporting monthly, users get a more timely view of brand competitiveness and consumer preference shifts. By clicking into the data, you can engineer quarterly views. Or you can subscribe to Foureyes inventory data to get the exact timeline you want, down to daily or going all the way back to January of 2020.

Q: Which brands are gaining the most market share right now?

A: Market share shifts monthly, and trends differ by region and body type. Check the live dashboard to see which brands are climbing nationally or in specific states. It’s free, updated monthly, and doesn’t require a login.

Q: What can regional sales data reveal?

A: State-level sales data highlights geographic differences in consumer demand. For example, SUVs may dominate in some regions. Or it can show temporary explanations for drops in performance. For example, a powerful hurricane in the Southeast could temporarily reduce inventory and sales in a cluster of states, explaining away a perceived downturn.

Q: Do analysts use this dashboard for forecasting?

A: Since the Foureyes Sales and Market Share Dashboard is free and requires no login, we don’t know the users. However, analysts across financial and predictive disciplines do subscribe to our inventory data to track month-to-month sales momentum, market share shifts, and regional variations to inform demand forecasts, identify early signals of consumer preference changes, and support valuation models. To learn more, contact us.

Q: What role does inventory play in shaping sales trends?

A: One driver of growth or decline can be supply constraints. We show supply data at a state-level side-by-side with sales to help analysts distinguish demand-driven changes from supply-side bottlenecks.

Q: How do incentives or new model launches show up in this data?

A: Spikes in monthly sales or increases in market share often reflect the impact of incentives, promotions, or new model introductions. By watching for these shifts, you can measure the effectiveness of market activity in near real time.

Q: Can I share insights from this dashboard?

A: Yes. You can cite the Foureyes U.S. Automotive New Vehicle Sales and Market Share Dashboard in your work, presentations, or media coverage. Please include a link back so readers can access the live dashboard. For media inquiries or comments from Foureyes, please contact us at hello@foureyes.io.
