I think race = nascar tracks
Full speed = no braking "don´t release the gas" if you must release gas, drift or brake its not a fs.
"Full speed with drift" may be another style = same as above, but the car slide some times, becouse the speed is to high to keep the grip, or you need to drift without release the gas.

I would say that no "official" definition should be made.

Styles are naturally somewhat subjective. Every person will have his own definition.

But I also believe many of us share a similar idea of what most of these styles are, even if we may not agree on the specifics.

Listed below is how I personally define these styles and modes. It's not meant to be definitive, but just to give an idea. There may be newer players who are just joining us, and it may give them a more well rounded view of what kinds of maps there are in the world of TM.

The list is also not exhaustive. There are no doubt styles which have a following of which I'm not familiar. Besides this, there are parts of the community that have different names for the styles I list below. I've only listed what I believe to be the most heard styles around TMX/MX.

I also believe that new styles will emerge, as they have with every new environment. So do NOT get locked into a certain genre. Be inventive, explore new ideas in the editor, and always see what's possible to push the boundaries of the game forward. Don't be afraid to blur the lines and create something fun and original.

Probably the highest honor an author can get is to be recognized as having his own style. GanjaRider maps are immediately identifiable, as are maps by Edge, Nukedragon, DaKKoN, arkone, tmjonas, and others. Their maps can surely be classified in the larger styles listed below, but they also transcend these styles and fully define their own mapping style with every map they release.

Without further ado, some styles and modes of TrackMania....

--------------------------------- STYLES in TIME ATTACK or ROUNDS --------------------------------------

Time Attack is all about setting the best time possible. You have a set amount of time on the server in which you can do as many runs as you want. When the timer hits 0:00, the person with the best time wins.

In Rounds everyone starts at the same time. It's all about placing as highly as you can to maximize your points for the round. Rounds mode has a point limit, for instance 125 points. Multiple runs are played by everyone on the server until someone goes over 125 points. When that happens, whoever has the most points wins.

Normal (or Race)
An easy or intermediate track that would be good for online racing. Some corners, but nothing too difficult. A very clearly designed route. Little to no transitions. A few jumps, but very easy ones. A good track for beginners to drive on. Alternatively, this could also be defined as a track which incorporates 2 or more styles listed below in a single map.

FullSpeed
A track which can be driven without letting off the gas for the entire run. Stylistically they usually have very gradual turns, which is fine because you're going at a very high speed. Big jumps, wallrides, loops, inversions, and corkscrews are common, but not required. The entire route is tuned to maximize speed. Boosters are used liberally, though they may only be needed at the start, in order to build up speed quickly.

Tech
A map, usually made for competitions or rounds mode. It will feature tight corners, a slower average speed, technical passages throughout. The track can have a lot of flow. Emphasis is put on perfecting a good driving line through the map.

SpeedTech
Similar to tech, but with longer turns. Sometimes boosters. A higher average speed than tech. Fast drifts.

Offroad
A track built with primarily the terrain blocks as a driving surface. These sections could be connected with small sections of road for CPs or to redirect the driver.

Laps
Pretty self explanatory. A map with more than one lap, using the lap start block as a starting point. The driving style of the track could be any of the other styles mentioned.

LOL
A short map, usually under 20 seconds. The map usually has one crazy idea in it that probably requires a perceived degree of luck to get a good time.

Mini
Similar to a LOL map in length, but stylistically more focus is placed on the track being technical. Skill will gain the best time, not luck.

Endurance
The style of the map may vary between tech, speedtech, and fullspeed... or even "normal". Generally the map is at least two minutes long. Many endurance maps are five or more minutes long. A good endurance map will not have any section that is too hard to pass, or blind for the driver. The route will be clearly defined, good signage is a must (where applicable). If reuses are used, they must be intuitive so the driver will not get lost. The route is usually varied so the driver will recognize each passage, even on successive runs. Traditionally, this style has been driven the most in the Coppers Millions Cup.

Transitional
The main focus of the map is placed on the transitions between blocks. Transitions are created when traversing on or off a part of a block that wasn't intended to be its primary use. This usually results in needing precision driving to navigate the transitions. The builder will usually set up a transition by setting up a driving line into the transition. This will enable the driver to naturally flow through the transition with little effort beyond needing to be lined up for it. Satisfaction is derived from successfully traversing each transition smoothly and completing the map with a good time. Difficulty may vary widely. Some maps may incorporate one or two transitions and still be focused primarily on tech or fullspeed. Whatever the primary focus of the map is defines it's category.

RPG
Think of them as Adventure maps. Generally it's understood that the map requires a texture mod. Much emphasis is put on epic scenery and a challenging route with many challenges. Depending on the difficulty, the driver may need to respawn repeatedly to refine their skills and pass on to the next section. The map is usually themed (e.g. An ancient temple, a spaceship, a boat, etc.). Driving on pipes and narrow walls is common, but not required. There is usually some intermediate driving between more challenging parts. Some believe RPGs also require a story with specific objectives, because you are role-playing (as the name RPG means Role Playing Game). Generally these maps are a little longer. On average they may take anywhere from 20 minutes to a couple hours to complete for an average driver. Those who are experts at the genre may complete the same map in about 5 to 15 minutes. Some more difficult challenges may have the driver traversing the map for several hours.You may also read the TrackMania RPG Blog's definition of RPG

Trial
Similar to RPG, but less about story and atmosphere. The track is usually not themed. More emphasis is put on individual sections being difficult to traverse. Generally there's not any easy driving. The map may have some very frustrating parts that require a seemingly inordinate amount of skill to pass. The degree of satisfaction from completion: very high.

Stunt
This was a category on TMUF TMX. It's not to be confused with Stunt mode. A track made in the Stunt style would feature a series of challenging stunts, like flips or halfpipe jumps, to pull off, connected by road passages. The goal is to set a good time while traversing the stunt parts with speed, not to get stunt points.

Maze
Probably multiple routes to the finish. Many dead ends. A confusing route. There could be hidden CPs if the author chooses. Or CPs could be used as waypoints so you know you're on the right path. Multiple vertical levels add length to the track. Alternatively this style is known as a labyrinth.

PressForward (aka PF)
Hold the Accelerator. 3 2 1 GO! Enjoy the show! These tracks require no driving at all. The author has already designed the entire route to be driven with only the forward key pressed. Generally the most exciting ones of this genre have the car flying through the track with much speed and doing things (usually with much precision) that you could never do as a normal driver. It's preferred if maps of this style are at least a minute long, though 2 to 3 minutes is even more rewarding to watch. The longer the map, the more work that goes into testing it during the build process. Spinoffs of this genre include PressRight (PR), PressLeft (PL), PressNothing (PN), as well as others. There have been some maps that also incorporate freestyle moves to dazzle the viewer.

-------------------------------------------- TIME ISN'T A CONCERN --------------------------------------------

Freestyle
An open map with different areas designed for freestyle driving. Think of it like a giant skatepark. Usually there are CPs at key points so you can respawn repeatedly to refine your skills on a certain grind or some other freestyle move. The goal isn't to finish, but to set up a good "run". Try to chain together as many cool tricks as you can to make an epic run. Save your replay, edit it to the applicable part, and share it with the freestyle community. This has been a very high profile part of TrackMania since it was first introduced/invented by the community.

Freeroam
An open map for casual driving. Not meant to be finished. No specific route.

Hide & Seek
A map with good spots to hide from your opponents. Similar to freeroam, but with the goal of finding other drivers.

------------------------------------------------- STUNT MODE ----------------------------------------------

Stunt mode is all about getting the most points you can before your timer runs out. You may have a minute or two to complete a stunt run before starting another. It's played online in much the same way as Time Attack in that you have maybe 6 minutes (or whatever the server is set at) in which to hone your "run" and get the most points. Finish before the timer runs out or risk losing all your points.

As of the writing of this post, it has not been implemented in Canyon yet.

I don't know the names of these styles. But I've observed some basic kinds of stunt maps...

• A map which requires you to drive from point A to point B through several CPs and stunt jumps or flips and get as many points as possible in the process.[/item]
  
• A map designed much like freestyle maps. Open, with many areas to rack up points. There is usually a central CP which you can respawn at, should you crash... with a loss of some points... but will allow you to rack up some more points before finishing at one of the many finishes scattered around the map.[/item]
  
• A map which starts with a quick CP... then a red booster and jump into the scenery outside the build area. Flips, bounces, crashes, all kinds of stunts can be chained together to maximize points. Usually the driver will respawn multiple times with a loss of some points, but with a goal to gaining many more each time. The finish is right next to the CP. When the timer runs low, you quickly drive in the finish with no loss of points.[/item]

----------------------------------------------------- OTHER ---------------------------------------------------------

In older TrackMania versions there was of course Platform and Puzzle modes as well. Quickly I'll summarize those.

Platform
There is no timelimit. The goal is to get through the map with as few respawns as possible. As a result, the map is designed with jumps that usually require air control. Engine killers may also make it difficult to get enough speed to make it to the next CP. The fewer respawns you take, the more points you get. Some also compete for best times, although that is not the primary goal of this mode.

Puzzle
You are given a set number of blocks that the author has chosen. Some blocks are already placed (and locked into their positions) in the map. Usually CPs, the Start, and the Finish. You must use the available blocks to build a route through the map to get the best time.

you writing nolifer

I'm loving the new 30,000 character limit!

I'm getting a 404 error when I click on the link.

eyebo says:
It seemed fitting to put it there.

it doesn't ^^

Okay, that part of MX isn't open yet. I didn't realize that. Oops!

Anyway, I've put my post back here again.

I realize now I went a little beyond the scope of the topic, which is just fullspeed.

Eyebo, you didn't went beyond scope of the topic. Fullspeed was only an example.
The question now would be if this should become (maybe after an improvement by the community) an official definition or just an overview for those confused by so many styles?
Well done eyebo!

I think a definition must be a bit more concise than the posted by eyebo. Anyway I think he defined quite well all styles.

My version:

Styles:
Fullspeed: You can/must finish it without using brakes and without letting off the gas.
Tech: Track based on drifting. You must use brakes to start drift.
Speedtech: I'm not sure about this. Where ends tech and starts speedtech? Nobody knows. XD
Fullspeedtech: You can/must finish it without using brakes and without letting off the gas. You must drift in some corners. (This means a drift because of a slide or a turning-jump with slide-landing. Remember: You din't pressed the brake button)
LOL: Usually short, track based on tricky stunts.
Stunt: Track based on stunts.
Normal/Race: Not sure again. Is this the definition for the tracks wich not fits on other styles? XD
PX: You have to press something all the time: PF, PB, PF+Left...

Not styles
This is just a description of the track itself. All descriptions can fit all styles.
Laps: Start and finish are in the same block.
Mini: Short track. (Under 30 seconds?)
Endurance: Long track. (Over 2 minutes? 5?)

i would say its like a bonus. Transitional Tech, Transitional Fullspeed etc etc^^ like an attribute
