From Board Game Geek:
Formula Dé is a fast-paced racing game in which the cars' top speeds are limited by having to end a certain number of turns in each curve of the racetrack. This can be tricky, because although players can regulate their speeds by choosing which gear to be in and each gear allows a certain range of movement, the exact amount is determined randomly. Great fun for a big group.
From the publisher:
We've been telling you about it recently - F1 is making a comeback in stores: Formula Dé is dead, long live Formula D! Get ready to push your engine to its limit, to hug the curves in the tight corners, but also to keep up with your opponents to take advantage of the air flow and pass them to win... Taking risks and planning ahead are two qualities you'll need as a pilot if you want to stand on the highest step of the podium! Formula D is also the excitement of illegal racing in the streets of big cities - anything goes: custom cars, nitro acceleration, drifting in the curves, dirty tricks... The game mechanics stay the same, but use specific rules, cars and tracks. You will also discover, in this new edition of Formula D, elements unseen up to now, such as painted race cars, dashboards, pilot profiles, and tracks... Very soon we'll unveil the new, high-tech elements which have been created in our ultra-secret lab.
