Forza Motorsport 6 is a single-player and multiplayer racing simulation game featuring over 450 licensed cars and 26 tracks from around the world. Players compete in professional-style motorsport events that emphasize authenticity, vehicle variety, and detailed environments.

The single-player campaign, called Stories of Motorsport, organizes races into themed series based on different disciplines and eras of racing. Players progress through championships that highlight touring cars, endurance races, muscle cars, and modern supercars, with narration providing historical and contextual information. Events are structured to showcase both high-performance vehicles and lesser-known categories, offering variety across multiple racing formats.

Gameplay retains the simulation focus of earlier entries in the series. Each car is modeled with attention to handling, physics, and customization, with options to adjust difficulty through assists such as braking lines, traction control, and rewinds. The Drivatar system, first introduced in Forza Motorsport 5, continues to generate AI opponents that mimic the racing styles of real players, offering competitive and adaptive challenges in both single-player and online races.

New to this installment is the introduction of wet-weather racing and night events. Rain affects traction, visibility, and braking distance, with puddles dynamically forming on the track surface to force changes in driving lines. Night races alter the experience further by reducing visibility and requiring careful use of headlights. Unlike fully dynamic systems, these conditions are tied to specific tracks and events, but they add additional challenge and variety to racing scenarios.

Multiplayer modes include both structured events and custom lobbies, allowing for races against AI or human opponents. Online play supports large grids of cars and includes competitive leagues, hoppers, and user-generated race formats. Split-screen multiplayer is also available for local play.

Secondary features include in-depth car customization with paint, decals, and performance upgrades. A progression system rewards credits and experience, which can be spent on acquiring new cars or tuning existing ones. Showcase events highlight unique challenges, such as racing against iconic vehicles or competing in special formats.

The presentation emphasizes broadcast-style authenticity, with commentary, race intros, and detailed replays. Track selection includes both real-world circuits, such as Daytona, Brands Hatch, and Circuit de Spa-Francorchamps, and fictional courses created for the series. Nine of the available tracks debut in this entry, expanding the series’ variety of racing environments.
