Rally racing is a motorsport in which cars start one at a time, usually a minute or more apart, and race the clock over closed point-to-point roads called special stages. Each car carries a driver and a co-driver, who reads pace notes, normally written on a slow reconnaissance drive. The crew with the lowest total time, stage times plus penalties, wins; a World Rally Championship round typically has 15 to 25 stages over three or four days. Mars Rally Championship, a free browser rally game, uses the same format: timed point-to-point stages and a co-driver calling pace notes.
What is rally racing, and how does it work?
Rally racing turns a road into a time trial. Organisers close a section of road, a forest track in Finland or an icy Alpine pass in France, and it becomes a special stage, numbered SS1, SS2 and so on. Cars start it alone, one to three minutes apart in the World Rally Championship (WRC), so nobody races side by side. The opponent is a time on a screen.
Each stage is timed to a tenth of a second, says the WRC's own explainer. A round's stages total about 350 km at most, and a single stage can be under 2 km or over 50 km.
The word rally also covers slower formats, such as regularity rallies scored on holding a set average speed; this post is about stage rally, the flat-out kind. Most free browser games with rally in the name fail that format, and our guide to the free rally games you can play online sorts out the ones that pass.
Rally vs rallycross, rally raid and circuit racing
Four disciplines share cars, dirt and sometimes the word rally.
| Discipline | How cars start | Course | Surfaces | One event | Navigation | Winner |
|---|---|---|---|---|---|---|
| Stage rally (WRC) | One at a time, 1–3 min apart | Closed roads, point to point | Gravel, asphalt, snow, ice | 15–25 stages, up to about 350 km timed | Co-driver reads pace notes from recce | Lowest total time, penalties included |
| Rallycross | Up to 8 side by side | Short circuit, lapped, with a joker section | Asphalt plus gravel or dirt | About 3-minute races: heats, then a final | None; learnt in practice | First across the line in the final |
| Rally raid (Dakar) | Staggered, against the clock | Desert and tracks between GPS waypoints | Sand, dunes, rock, gravel | Dakar 2026: about 8,000 km, nearly 5,000 of them timed | Organiser's roadbook, no recce | Lowest total time, penalties included |
| Circuit racing | The whole field together | Closed circuit, lapped | Mostly asphalt | Laps or a set time on a known track | None | First across the line |
Rallycross began as rally cut down for television. The first event ran at Lydden Hill in Kent on 4 February 1967, and the TV producer behind it, Robert Reed, wanted to reduce "seven days and 3,000 miles to seven minutes and one mile". Cars race door to door, and in many series each must take a longer joker section at least once per race, which is where the tactics live.
Rally raid is off-road rallying on a far bigger scale. Its best-known event, the Dakar Rally, ran from 3 to 17 January 2026 in Saudi Arabia: a prologue and 13 stages. Nobody gets a recce or pace notes. Crews navigate from the organiser's roadbook between GPS-checked waypoints, and on marathon stages they spend the night at a bivouac without their mechanics.
What happens between rally stages?
Between the stages run road sections, or liaisons, on open public roads, where crews drive among ordinary traffic and keep to the speed limits. That is why a rally car must be road legal.
Each road section has a target time and ends at a time control, where the co-driver hands in the time card. Under FIA rules, checking in late costs 10 seconds a minute and checking in early costs a full minute a minute. The asymmetry has a purpose: arriving early must never pay, or crews would race on public roads.
A WRC day usually has three timed service stops: 15 minutes in the morning, 30 at midday, cut from 40 in the FIA's 2026 rule update, and 45 in the evening. Overnight the cars sit in parc fermé, where nobody may work on them. Between services, only the crew may work on the car, with the tools and spares it carries.
Recce, pace notes and the co-driver
No crew may practise a stage at speed. Most rallies allow recce instead, short for reconnaissance: in the WRC, two passes of each stage in a road car, under a GPS-enforced speed limit, with the driver dictating notes to the co-driver. Some national rallies allow none, and the co-driver reads the organiser's route book.
Pace notes give a distance, a direction and a severity for each corner, usually on a 1-to-6 scale that our explainer on the 1-to-6 corner system decodes. The co-driver reads them a call or two ahead of the car and runs the time card between stages. What a rally co-driver does covers the seat in full.
How is a rally won?
A rally is won by the lowest total time: every special-stage time plus every penalty. A stage win is worth only the time it gains, so a crew can win a rally without setting a single fastest time.
Take two crews over three stages. Crew A wins two by 3.0 seconds each and crew B wins the third by 5.0 seconds, so A leads by 1.0 second on stage times. If A checks in two minutes late at a time control, the 20-second road penalty hands the rally to B by 19 seconds. Checking in one minute early would have cost A a full minute.
Points decide the championship, not the rally. In 2026 the WRC pays 25, 17, 15, 12, 10, 8, 6, 4, 2 and 1 to the top ten overall, plus 5 to 1 for the fastest five over Sunday's stages, the Super Sunday classification, and 5 to 1 on the Power Stage, the rally's last stage. A perfect weekend is worth 35 points.
Surfaces, cars and the 2026 WRC season
Rally runs on whatever surface the road has. As of September 2026 the WRC season has 13 rounds on four continents, after Rally Saudi Arabia was dropped from the original 14. Eight are on gravel: Kenya, Portugal, Greece, Estonia, Finland, Paraguay, Chile and Sardinia. Four are on asphalt: Monte-Carlo (often icy), Croatia, the Canary Islands and Japan. Sweden runs on snow. Sardinia, on 1 to 4 October, is now the final round.
Gravel adds a handicap with no circuit equivalent: the first car on the road sweeps the loose stones off the line for everyone behind it. So start order matters: on the first full day of a WRC round the championship leader usually starts first, paying for the lead.
The cars come in five classes on the FIA's Rally Pyramid, and WRC events run the top three. Rally1, the top class, lost its 100 kW hybrid unit for 2025, with the air restrictor cut from 36 to 35 mm and the minimum weight from 1,260 to 1,180 kg. Rally2, a 1.6-litre turbocharged four-wheel-drive car, fills WRC2, the FIA's regional championships and many national ones. Rules confirmed for 2027 move the top class to spaceframe cars built to a €345,000 cost cap, with Rally2 cars eligible alongside them.
What a rally game can copy, and what it cannot
A game can reproduce a special stage closely and everything around it barely at all. In Mars Rally Championship each stage is a timed point-to-point run through checkpoints: Stage 2, The Long Run, is 2,306 metres through 12 of them, and Stage 1, The Opener, 1,164 metres through 8, both short next to a WRC stage. The co-driver calls on the same 1-to-6 scale, with notes derived from each stage's checkpoint geometry, shown on the HUD and spoken on an 8-second lookahead, because braking from 100 km/h on Mars takes about 125 metres.
The Mars Cup runs the open stages back to back on one cumulative time, and damage carries from one stage to the next. The repair zone sits at each stage's start: the rover heals there at 20 HP a second, but only while stopped, and the clock keeps running. Restart mid-cup and the cup ends: like a real crew, you get one run at each stage.
What the game leaves out is everything between the stages: recce, road sections, time controls and a service park. With one rover there are no classes or championship points, and on a single-stage run you can restart as often as you like, which no real crew gets.
Mars Rally Championship is free, runs in a browser tab with no download and no account, and works on a phone or a school Chromebook. Up to 8 pilots can race a stage at once, with no collisions, each timed from their own start.
Where to try this
- Run the Mars Cup: both open stages on one cumulative time, damage carried over.
- The stage list has both routes, their lengths and their medal times.
- Games like DiRT Rally sorts the rally sims worth installing, free and paid.
- How to get faster at rally games covers braking points and exit speed.
