How Much Quicker Is the Newest Version of Tesla FSD? This Test Put It Against Old Software to Find Out
A reaction-time test pits the latest Full Self-Driving software against an older build to measure real-world gains.
A new test from InsideEVs set out to measure how much quicker the newest version of Tesla's Full Self-Driving software is by running it head-to-head against an older build, with reaction time as the metric.
What Happened
The comparison focused on hardware response and reaction-time performance between the latest FSD release and prior software. The test was designed to quantify whether the newest version delivers a measurable speed advantage in how quickly the system reacts while driving.
Why It Matters
For owners, faster reaction time can translate into smoother, more confident behavior in real-world scenarios where split-second decisions matter. For buyers weighing an FSD subscription or upgrade, it offers a concrete way to judge whether newer software versions are meaningfully better than what came before.
The Bottom Line
The test puts the newest Tesla FSD version directly against older software on reaction time — a useful benchmark for anyone tracking how much progress each update actually brings.
