Horizon Driving Simulator

Opening Horizon Driving Simulator for the first time presents a familiar sight: a garage with a single car, a few buttons for tuning and customization, and a map showing available races. The game wastes no time throwing players into its open-world driving experience, but the initial impression is heavily shaped by what happens after the first few minutes. Players quickly discover that the game's promise of "ultimate open-world driving" comes with a set of practical realities that shape every session.

The setup process is straightforward. After a short loading screen, the player is placed in a garage with a basic vehicle. The interface is clean, with clear icons for performance tuning, visual customization, and race selection. However, the onboarding does not explain how the tuning system interacts with the visual customization, nor does it warn about the potential for bugs that can erase hours of work. This lack of guidance becomes apparent when players begin experimenting with the deeper systems.

Performance tuning in Horizon Driving Simulator is surprisingly detailed for a mobile game. Players can adjust turbos, pistons, intakes, and transmissions, each affecting acceleration, top speed, and handling. The game also allows adjustments to aerodynamics, tire pressure, and suspension. These settings can dramatically change how a car behaves on different tracks. For example, lowering tire pressure improves grip on off-road sections but reduces top speed on highways. Players who take the time to fine-tune these parameters often report a noticeable improvement in race performance.

When Tuning Meets Customization: A Clash of Systems

Where the game's complexity truly shines—and falters—is in the interaction between performance tuning and visual customization. Players can spend considerable time adjusting engine components to shave seconds off lap times. Then, they can switch to the visual editor to apply custom paint jobs, vinyls, and wide-body kits. The visual editor is robust, allowing for detailed decal placement and color selection. However, a recurring issue emerges: after applying a custom paint job and exiting the editor, the paint job sometimes disappears upon entering a race or reloading the garage. This is not a one-off glitch; multiple user reviews across both Google Play and the Apple App Store report the same problem. The frustration is compounded because the game does not save visual customizations reliably, forcing players to reapply their designs repeatedly.

This clash between the two systems highlights a deeper problem: the game's physics engine does not fully integrate visual modifications with performance changes. A wide-body kit, for instance, should theoretically alter aerodynamics and weight distribution. In Horizon Driving Simulator, however, visual mods appear to be purely cosmetic. They do not affect handling or speed. This disconnect between what the game visually represents and how it actually performs can be jarring for players coming from more simulation-focused titles like Forza Horizon. One player noted that the game "offers a similar driving simulation experience to Forza Horizon, great for those wanting a taste of Forza," but also pointed out that "the vehicle physics are not identical to Forza Horizon." The lack of integration between visual and performance systems is a key reason why.

The Reality of Performance: Ads, Bugs, and Offline Mode

Real-world performance of Horizon Driving Simulator is a mixed bag. The game runs smoothly on most mid-range devices, with users praising its optimization. "It runs smoothly on low-end devices, making it accessible to a wider audience," one review stated. Graphics are another strong point, with multiple users describing them as "great" and "reminiscent of Forza Horizon." However, the game's performance is hampered by two major issues: excessive ads and a broken offline mode.

Advertisements appear frequently, often between races and during menu transitions. While the game is free, the ad frequency has been a point of contention. One user on the Apple App Store complained, "โฆษณาเยอะไปหน่อย" (too many ads), while another on Google Play noted that ads interrupt the flow of gameplay. The offline mode is an even more significant problem. The game's description suggests it can be played without an internet connection, but multiple users have reported that this is not the case. "I couldn't play it offline it said it was an offline game but no," wrote one frustrated player. This discrepancy between the advertised feature and the actual experience undermines trust in the developer.

Bugs are another persistent issue. Beyond the paint job glitch, users have reported cars disappearing from their garages, the nitrous system failing in drag races after updates, and occasional crashes during stunts. One user on Google Play wrote, "我玩了一年半我的車不見了" (my car disappeared after a year and a half), indicating that progress loss can be severe. The developer, JM Game Studios, has released multiple updates addressing "bug fixes" and "performance optimizations," but the changelogs are often vague, listing only "resolved various issues" without specifics. The most recent update (v2.6.4) added a new car and redesigned stunt ramps on the Airport map, but did not address the paint job or offline mode complaints.

Technical Details and Version History

Horizon Driving Simulator requires Android 7.1 or higher, making it compatible with devices released in the last several years. The APK size varies by version, with the latest builds hovering around 155 MB. The game also supports controller input, including PS4, PS5, and Xbox controllers, which is a welcome feature for players who prefer physical controls over touchscreen. The iOS version requires iOS 15.0 or later and has a significantly larger file size of approximately 530 MB, suggesting different asset optimization between platforms.

The version history shows a pattern of incremental updates. Version 1.8.1, released in October 2025, was 124.7 MB. By version 2.5.3 in June 2026, the size had grown to 155.8 MB. The most recent version as of this writing is 2.6.4, released on June 25, 2026. The changelog for 2.6.4 includes a new car, track improvements (redesigned stunt ramps on the Airport map), and the usual "bug fixes." However, the persistent issues with paint jobs and offline mode suggest that the core problems remain unresolved. The developer has not publicly acknowledged these specific bugs, and the vague changelog entries do little to reassure users.

The game's permission requests are not detailed on the Play Store page, but based on similar racing games, it likely requires storage access for saving game data and possibly location for GPS-based features (though this is not confirmed). The app's privacy policy indicates that data is encrypted in transit, but some data is shared with third parties, including location and financial information. This is a concern for privacy-conscious users, especially given the game's free-to-play model with in-app purchases.
