All drag race events in Forza 3 are limited by horsepower and power train, and they take place on our eighth-mile and quarter-mile drag strips (although we also have the one-mile and half-mile drag strip tracks in the game as well)
Each drag event is a series of three race days, and each race day consists [of] three heats. In classic tournament style, the winners of each race face each other in the next round while the losers are matched up.
We've added 50 percent more car upgrades to Forza 3 from the previous game, which already had plenty to begin with. That said, we don't have specific drag racing part upgrades, like line lock, drag-specific fuel pumps, or drag-specific superchargers. What we've got are a ton of upgrades to mix and match, such as different tire compounds and separate front and rear tire sizes. Managing these upgrades can make your car very good at launching--drive train swaps, engine swaps--basically all the components that make your car really fast for drag racing
Tire temperature is already set to [an] optimum condition to maximize grip. We initially designed a burnout and staging-style minigame within the mode, but it just didn't feel like Forza. We really wanted to emphasize the skills of tuning and racing, not burnout and staging. Instead, we decided to emphasize tuning and racing. We will have plenty of folks who will dominate the drag racing scoreboards because they're going to understand it's not just about holding down the right trigger button when the tree lights up. For instance, launching a car efficiently off the line is a carefully learned skill. Traction control doesn't kick in at launch. Plus, automatic does not shift as quickly as manual transmission, and using manual with clutch gets you even faster shift times still. So those who master manual transmission and manual with clutch will be cutting off small amounts of time with their shifts, and in drag racing, every tenth of a second counts.
It's even possible to get multiple cars on the grid drag racing simultaneously, which makes for some interesting team-based battles. By default, it's set up to be a heats-based tournament.
