The final DLC package is titled 'Colin McRae: Flat Out'. The release of downloadable content follows a fortnightly schedule, and includes the return of rally locations from the first game, as well as cars such as the Škoda Fabia and BMW M1. Codemasters later introduced a more comprehensive tutorial for setting up the car to make the process more accessible for newcomers, amateurs and players who have been deterred from exploring setup options in the past. Players are also able to make a wider range of strategic choices, such as tyre compounds softer tyres offer more grip but wear out faster, while harder tyres are more durable but produce slower stage times. Damage sustained during a rally carries over from event to event. However, other elements such as customising liveries, signing sponsors and expanding team facilities were removed. The 'My Team' mode introduced in Dirt 4 is expanded upon, requiring players to hire specialist engineers to maintain the car. There is no rewind function and damages not only have a visual but also mechanical effect, with it being possible to sustain 'terminal damage', which automatically ends whatever race the car is in as a DNF. The gameplay therefore demands maximum concentration, especially as some stages can take more than ten minutes to complete. The surface of the stages is also subject to degradation as more cars pass over a stage, more than 100 layers ensure that the road surface will start to shift and break up, affecting grip levels. The weather also affects visibility in stages. The game also features a new weather modelling system where changes in the weather affect the relative level of grip and require players to take a more nuanced approach to driving. Every car can have its setup adjusted before a race.

This was later expanded to thirteen locations through downloadable content. Dirt Rally 2.0 lets players choose between a total of fifty cars, including the aforementioned World Rallycross Supercars, historic rally cars from the 1960s through the 1980s, Groups A, B and R rally cars, and modern rally cars from the 1990s to the late 2010s. There is also a rallycross mode with World Rall圜ross Supercars (including the lineup of the 2018 season) and eight circuits from the FIA World Rallycross Championship.

These stages are remastered versions of the stages included in the original Dirt Rally. Codemasters also announced plans to expand the game through the release of downloadable content, and released stages in Finland, Germany, Greece, Monte Carlo, Sweden and Wales. The game features stages in Argentina, Australia, New Zealand, Poland, Spain and the United States. Players compete in timed stage events on tarmac and off-road terrain in varying weather conditions. Dirt Rally 2.0 is focused on rallying and rallycross.
