Rally Pace Notes Explained: What Every Number and Call Means
Rally Pace Notes Explained: What Every Number and Call Means
Watch an onboard rally camera for the first time and the first thing you'll notice, after the noise, is that the co-driver never stops talking. A string of numbers and short words, rattled off calmly while the car is doing everything it can to throw both of them off the road. To anyone new to the sport, it sounds like a foreign language. It basically is one — just a very efficient one.
Why rally needs this system at all
In circuit racing, a driver learns a track by driving it over and over until the layout is memorized. Rally doesn't offer that luxury. A stage might only be driven once, ever, at competition speed, on a public road that changes with the weather and the light. Reacting to what you can see through the windscreen simply isn't fast enough — by the time a driver can properly see a blind crest or a tightening hairpin, they're already too late to set the car up for it.
Pace notes solve this by moving the information earlier. Before the event, the crew drives the stage at a controlled pace and writes down exactly what's coming, corner by corner. On event day, the co-driver reads those notes back in real time, timed so the driver hears about a corner just before it arrives — not when they can see it, but when they need to already be reacting to it.
Reading the numbers
The core of most pace note systems is a severity scale, usually running from 1 to 6:
1 is about as tight as a corner gets — close to a hairpin. 6 is barely a corner at all, fast enough that a skilled driver might barely lift off the throttle.
Everything in between is a gradient. A "3" is a solid mid-speed corner; a "5" is fast and confident. The scale isn't universal between every co-driver or every rally system in the world, but the shape of it — low number means slow down a lot, high number means barely slow down — holds everywhere.
The words that come with the numbers
Numbers alone don't capture everything a driver needs to know, so a handful of short modifiers do the rest of the work:
"Tightens" — the corner gets sharper as it goes on, so don't commit to full speed too early. "Opens" — the opposite: the corner relaxes, so there's more room to carry speed on the way out. "Long" — the corner lasts longer than its number alone would suggest. "Into" — there's no gap before the next corner; the two should be treated as one continuous read, not two separate decisions. "Crest" — a blind rise in the road. Depending on speed, a crest can turn into a genuine jump, which is usually called out separately. Cautions — anything that doesn't fit the corner-by-corner shorthand: a bridge, a water splash, an off-camber bump. These get flagged on their own because missing one can end a rally outright.
Put together, a real call might sound something like "left four into tightens three, don't cut" — a fast-ish left-hander that gets sharper as it goes, immediately followed by another corner, with a warning not to clip the inside apex. All of that, delivered calmly, with maybe two seconds' notice, at well over 100 km/h.
Why the co-driver's job is harder than it looks
The driver gets to focus entirely on the car. The co-driver is reading notes off a page, tracking distance traveled, and doing it all while experiencing every bump, crest, and near-miss the driver is causing — without a steering wheel to brace against. A small misread, or a note that doesn't match what's actually on the road that day, can be the difference between a clean stage and a rally-ending mistake. It's easy to watch a rally and only notice the driver; the results usually say otherwise.
Where this shows up beyond real rallying
This same tension — trusting a plan made in advance versus reacting to what's actually happening — is exactly why co-driver skill matters as much as it does in games that simulate rally management. In Overcrest, a co-driver's notes accuracy is a real stat that affects how often a driver gets caught out mid-stage, alongside a separate calmness rating for how well they hold things together when a stage goes wrong. It's a small detail, but it's there because the real skill it's modeling is genuinely that important.
