Heat: Pedal to the Metal was already a remarkably complete racing game, so the challenge for any expansion is not to fix what was never broken, but to find new ways of making us reconsider the road ahead. Heat: Rocky Roads, published by Days of Wonder and Asmodee, takes the familiar 1960s Grand Prix setting and adds two new circuits, a ninth racer, fresh upgrade and sponsorship cards, and another four Championship events. The result is very much an expansion rather than a reinvention, but that is hardly a problem when the underlying game remains as enjoyable as it was when we first reviewed it. The new content mostly succeeds because it understands exactly what makes Heat work: every extra rule needs to feed back into that wonderfully tense balance between speed, positioning and engine management.
The most substantial additions are the Germany and South Africa circuits, and they offer noticeably different challenges. Germany introduces another use of chicanes, where two consecutive corners force us to think about our speed over a sequence of turns rather than treating each bend as an isolated obstacle. The circuit otherwise gives us some welcome breathing room, with long stretches where building speed and setting up the next technical section become equally important. It is perhaps the more immediately accessible of the two tracks, and its chicanes fit naturally into the existing rules without requiring players to learn an entirely new system. At the same time, that familiarity means Germany does not radically alter the way Heat plays. It is a good track, but those hoping for another major twist may find it somewhat conservative.
South Africa is where Rocky Roads becomes considerably more interesting. Its defining feature is gravel, with numerous spaces around the corners carrying a simple but effective penalty: if we finish our movement on gravel, we must discard a Heat card from our engine if we have one available. It sounds minor, but because Heat cards are such a precious resource, the effect can dramatically influence which racing line we choose. Suddenly, taking a seemingly advantageous slipstream or pushing a little farther around a corner can leave us paying for it afterwards. The seven-corner circuit consequently demands much more attention to positioning, and several of its slower, tightly spaced bends make successfully navigating the course feel like a test of precision rather than simply speed. It can be punishing, particularly when we fall behind early, and the length of the circuit can make that deficit feel difficult to recover from, but experienced players may find precisely that tension its biggest attraction.
That interaction becomes even more compelling when the expansion’s new Sliding Skirts upgrades and sponsorship cards enter the picture. These introduce an Extra Slipstream effect that can be activated during the appropriate movement step, allowing us to perform another slipstream in the same turn and carry applicable bonuses into that additional movement. The potential is considerable: a well-timed combination can turn a car sitting several places back into a serious threat on a long straight. Naturally, it is not something we can simply activate whenever we want, since slipstreaming requires other cars to be in the right positions, which makes these cards more situational than their raw power initially suggests. That is actually what keeps them interesting. A spectacular multi-car chase can produce one of those memorable Heat moments, while a poorly timed upgrade can simply occupy space in our hand.
The additional cards also feed nicely into the Championship system. Four new Event cards allow the two new circuits to become part of a longer season, preserving one of the base game’s best features: turning individual races into a broader campaign where our decisions and upgrades carry forward. The selection here is somewhat modest, however, especially for players who already own the previous expansions. Nineteen new Upgrade and Sponsorship cards is useful rather than transformative, and the Championship additions could have benefited from more variety. The larger card pool can also dilute the chances of seeing specific upgrade types in smaller games, meaning that some of the new ideas will naturally make a greater impact with larger groups. Still, the new content is easy to integrate, and Rocky Roads does not burden the excellent underlying system with unnecessary complexity.
Then there is the new white racer, complete with matching player board, gear lever and starting deck. Adding another player is hardly a glamorous feature, but for a game that already thrives when several cars are battling for position, it is a practical and welcome addition. The new components match the established visual language closely, while Vincent Dutrait’s artwork once again gives the tracks a colorful period-racing identity rather than making them look like generic modern circuits. The boards are attractive without sacrificing readability, and the chunky cars and gear levers remain among the most satisfying physical elements of the game. Production quality is consequently exactly where we would expect it to be from a Days of Wonder release. Our only real complaint is one of practicality: once several expansions are combined, the original storage solution becomes increasingly awkward, with some of the additional cars and player components lacking dedicated space.
Ultimately, Heat: Rocky Roads does not make the mistake of trying to reinvent Heat: Pedal to the Metal. Instead, it expands the game’s racing vocabulary with two worthwhile circuits, a clever new way of exploiting slipstreaming and the useful option of bringing another racer to the starting grid. Germany is the safer and more immediately approachable addition, while South Africa is the more distinctive track and arguably the one that gives experienced players the most to think about. It is also an expansion that is easier to recommend to people who already know they love Heat than to newcomers, because the base game remains the essential purchase and Rocky Roads is ultimately more about extending an excellent formula than transforming it. For dedicated Heat players, however, that may be exactly the point: there are more races to win, more opportunities to burn through our engine’s reserves and, thanks to that extra slipstream, a few more ways to steal victory from someone who thought they were safely in front.
