Pick the tool that matches how you work: quick run timing, dash-mounted feedback, phone-based logging, or deeper coaching data after the event.
How we chose
This roundup favors short-course autocross needs over road-course feature lists. The main filters were startup speed, display readability, predictive timing behavior, data depth, and whether the unit makes sense when runs are separated by only a few minutes.
We also weighted cockpit visibility and mounting, because a timer that hides in a phone screen or takes too long to stage can be the wrong tool even if it has more features on paper.
Where the choice is between a standalone display, a phone app, and a logger, the decision should follow your workflow. If you want the simplest timing check, the display matters more than video. If you want coaching, you need data you can review later.
Autocross lap timer decision matrix
| Option | Course suitability | Startup speed | Display readability | Predictive timing | Data depth | Ideal driver type |
|---|---|---|---|---|---|---|
| Racelogic VBOX LapTimer | Very strong for short, low-speed course runs | Fast once mounted and powered | Strong standalone visibility | Yes | Moderate to deep, depending on workflow | Driver who wants instant feedback without a phone |
| AIM Solo 2 | Very strong for autocross staging and repeat runs | Fast dashboard workflow | Clear 2-inch display | Yes, through lap timing workflow | Moderate, with track database support | Driver who wants a dash-mounted timer with simple review |
| Dragy DRG70 | Strong if you are comfortable with a phone-first setup | Slower than a dedicated screen if the phone is not ready | Depends on the phone and mount | Yes | Moderate, with 3D replay in the app | Driver who already prefers app-based logging |
| Racelogic PerformanceBox | Good for mixed autocross and straight-line testing | Good as a standalone logger | Useful, but less focused on quick glance timing than a dedicated lap timer | Yes for timing use | Higher, with straight-line and G-force data | Driver who wants broader test data, not just run times |
| VBOX Video HD2 | Best when you want review, not the fastest staging workflow | Slower because video and overlay setup matter | Depends on how you review footage later | Timing is part of the system | Very high | Coach or driver building a coaching archive |
| Phone app plus Multi-GNSS receiver | Usable, but less ideal when runs are short and staging is rushed | Can be quick if the app stays ready | Depends on phone placement and sunlight | Often yes, app-dependent | Moderate | Budget buyer who accepts workflow compromises |
| Starlane CORSARO-II R GPS Lap Timer and Data Recorder | Strong for drivers who want a dedicated logger with predictive timing | Good standalone workflow | Good as a dedicated unit | Yes | Moderate to high | Driver who wants a cableless standalone recorder |
Racelogic VBOX LapTimer: best for fast standalone timing
The VBOX LapTimer fits drivers who want a dedicated, standalone unit with fast readout and predictive timing. Racelogic lists it as a 25 Hz GNSS data logger and predictive lap timer display, and it is positioned for track use with instant driver feedback.
That matters in autocross because the useful part of the run ends quickly. A glanceable display can tell you whether a change helped before you leave the grid area for the next pass.
The drawback is simple: this is built around timing and feedback first, not around a phone-style experience or all-in-one video review. If you want the deepest post-run coaching layer, you will need more than the base timer.
AIM Solo 2: best for dash-mounted timing
The AIM Solo 2 suits drivers who want a dashboard mount, Bluetooth connectivity, and a compact screen they can read without reaching for a phone. AIM lists a 2-inch display and a database of more than 2,000 tracks, which helps when you want a dedicated timer with a familiar workflow.
For autocross, that combination is useful because the timer stays visible during staging and between runs. The shorter the course, the more valuable a quick glance becomes.
The main drawback is that a 2-inch display is still a small display. If you want richer analysis than timing and basic session reference, you may eventually want a separate logger or video workflow.
Dragy DRG70: best for phone-first users
The Dragy DRG70 is the better fit if you want the timing device to live behind the app. Dragy says it supports up to 25Hz GPS laptiming, and its app includes predictive timing and 3D map replay, so it leans toward a smartphone-dependent workflow.
That can work well for drivers who already keep a mount in the car and like reviewing sessions on a phone after the run. The Bluetooth connection also keeps the hardware side light.
The tradeoff is startup discipline. If the phone is not ready, the workflow is slower than a dedicated display, and sunlight can make quick glances harder than they are on a purpose-built screen.
Racelogic PerformanceBox: best for mixed test data
The PerformanceBox is the right choice when autocross timing is only part of the picture. The same source lists it as a 10 Hz GPS data logger that measures lap and split times, G-forces, speed, braking distance, and straight-line checks such as 0-60 and 0-100 testing.
That makes it useful if you want one device for cone-course runs and other setup checks. If a suspension change affects braking or launches as much as corner exit, this kind of logger gives you more than a single time on the screen.
The drawback is focus. A 10 Hz logger can be enough for many short-course drivers, but it is less centered on quick standalone display timing than a purpose-built lap timer.
VBOX Video HD2: best for coaching and review
VBOX Video HD2 is the best fit when review matters more than instant timing. The same source describes it as a dual-camera 1080p video system with GPS data logging and a live graphical overlay, which is the kind of setup a coach can use to connect driving inputs to what the car did on course.
This is useful if you want to compare lines, hand position, or where the car picked up speed after a slalom. A logger plus video is more work to set up, but it gives you far more context after the run.
The drawback is obvious: it is not the fastest path if all you want is a simple time between runs. It is a review system first.
Which one should you buy?
If you want the fastest autocross workflow, start with a standalone GPS timer. If you want the cleanest cockpit view, choose the unit with the easiest display to read in bright light. If you want coaching, move up to video or deeper logging only after the basic timing workflow is solved.
As a rule, choose timing first, analysis second. A phone app or a feature-heavy logger can be a good fit, but only if it still lets you stage quickly and read the result without digging through menus.
Say your runs are short and the grid is busy. A timer that wakes instantly and shows a predictive split is more valuable than a system that can do more things after you get home.
Suppose you are chasing a setup change on a 45-second autocross course. A display that shows immediate driver feedback can tell you whether the change helped before the next run cools off in the paddock.
Solo use case
Pick a standalone timer if you want repeatable run data with the least distraction. For solo autocross, quick acquisition and an easy-to-read display matter more than a long feature list.
Pro use case
Pick a logger if you want to compare runs, see split behavior, and review braking or speed data after the event. The PerformanceBox and VBOX Video HD2 are the more serious paths here because they add context beyond a single time.
Coach use case
Pick a video-plus-data workflow if you are trying to show a driver what changed from one run to the next. The overlay and replay matter because they connect the number on the screen to the line and inputs that produced it.
- Confirm the workflow. Decide whether you need a standalone display, a phone-first app, or a logger with review software.
- Check the screen and mount. In autocross, a readable display and a secure cockpit position are worth more than extra menu depth.
- Match data depth to your goal. Use a simple timer for run-to-run comparison, then move to video or straight-line logging only if you need coaching insight.
How to choose
Start with the course, not the spec sheet. Autocross rewards fast wake-up, predictive timing, and a display you can read in the car without losing focus on the course worker, the starter, or the next grid spot.
Then decide whether you need standalone timing or deeper analysis. A GPS lap timer gives you predictive lap timing, lap and split timing support, and repeatable run data. A data logger adds more context, and a video system adds the most review value.
For many autocross drivers, the biggest question is not whether a unit has the most features. It is whether the unit gets you a clean number fast enough to use it before the next run.
What is the best lap timer for autocross drivers?
For most autocross drivers, the best lap timer is a GPS or GNSS unit with a fast receiver, predictive timing, and a display you can read at a glance. The best choice depends on workflow: standalone timing for speed, phone-based timing for flexibility, and logging systems when you want coaching data after the run.
Do I need GPS or an app for autocross lap timing?
GPS or GNSS timing is usually the better fit for autocross because it gives you repeatable run data, predictive timing, and split support without depending entirely on the phone’s interface. An app can work, but a dedicated timer usually starts faster and is easier to read in bright paddock light.
How accurate are phone GPS lap timers at autocross?
Phone GPS lap timers can be useful, but their accuracy depends on the phone, the app, the mount, and how well the receiver maintains a stable fix. On short autocross courses, the bigger issue is often workflow: if the app is slow to open or hard to read, the timing data is less useful in practice.
Can a lap timer show predictive lap times and deltas?
Yes. Predictive lap timing is one of the most useful features for autocross because it lets you see whether the current run is quicker before the run is over. Delta-style feedback matters when you are comparing setup changes, because it helps separate a better line from a worse one more quickly.
Which lap timer works best without a dedicated screen?
A phone-first unit works best if you do not want a dedicated screen, but it is a compromise. Dragy-style workflows can be convenient, especially with Bluetooth and app replay, yet a separate display is usually easier to glance at during autocross staging and between runs.
What features matter most for short autocross courses?
Short autocross courses reward quick startup, strong cockpit visibility, predictive timing, and enough GPS or GNSS update speed to keep the timing stable through quick direction changes. Data depth matters too, but only after the device can show a useful result fast enough to guide the next run.
Is a 10 Hz GPS lap timer enough for autocross?
For many drivers, yes. A 10 Hz GPS lap timer can be enough for autocross because the runs are short and the practical need is repeatable timing, not endurance-race telemetry. Faster 25 Hz units can add value when you want finer data resolution or more immediate driver feedback.
What’s the difference between a lap timer and a data logger?
A lap timer focuses on timing a run and giving you a result quickly. A data logger records more detail, such as speed traces, G-force, braking distance, replay, and sometimes video. For autocross, a timer helps you pick the next setup change; a logger helps you explain why the change worked.
