The Formula R is a racing car that only appears in Grand Theft Auto: Chinatown Wars.
The Formula R assumes the design of a modern Formula One racing car, and as a result is not meant to be roadworthy and available on the streets of the game. The car's performance is predictably of the highest end, being very fast in acceleration and top speed, although its steering and brakes remains average-to-good; its durability is also poor than average, owing to its construction.
The Formula R is only obtainable after unlocking the BOABO Auto Merchant feature and attain bronze medals in all street races, to which point the car will become available at the Auto Merchant for $5,000 each. However, one can get a Formula R without this method by doing the S&M Grand Slam race. With opponents being Formula Rs, one must not finish the race but instead go to the finishing line once the other drivers have completed. Using your car, push the Formula R towards your nearest safehouse and try to push the vehicle into the garage from the side. When driven out, the car will be unlocked.
