Garages

The first garage you inhabit provides you with the ability to store two cars and to have one driver and support mechanics.

Upon completing the first local grand prix, you are upgraded to the second garage. The second garage now allows you to hire a second driver. Additionally you can now house four cars and four mechanics per driver.

After clearing the Japan level grand prix, you move onto the world level and are now given the largest garage. It's now possible to build and store six cars as well as six mechanics per driver.

Car Bodies

Basic
Roadster The Roadster is the most basic car. Better suited to asphalt then ice, but can be upgraded to be a passable vehicle. Allows two additional add-ons and can be successfully produced by a level 1 mechanic.

Off Road
Buggy The Buggy is the entry level off-road car. It allows 3 parts to be added on and is fair on dirt and ice. Requires a barely trained mechanic for optimal build. Unlocked by upgrading Roadster 25%. Upgrade 50% to unlock The Proto Car.
Proto Car The Proto Car is an upgraded buggy. Better overall stats but remains a good car for dirt and ice. Upgrade 50% to unlock The Super Car. Requires a good mechanic for optimal build.
Super Car The Super Car is the final upgrade to the buggy. It carries 4 slots for add-ons and has very high speed and durability. Unmodified it is not suitable for ice. Requires expert mechanics for optimal build.

Drag Cars
Dragster The Dragster is the entry level high speed car. It allows 2 parts to be added on and is weak on dirt and ice. What the car lacks in durability it makes up for in speed. Moderate mechanic required. Available by winning the Snowville GP. Upgrade to 50% to unlock the Cigar Car.
Cigar Car The Cigar Car is the second version of the Dragster. Improvement over all basic stats, remains unsuitable for any surface except for asphalt. Well trained mechanics needed. Upgrade to 50% to unlock the Spiral Car.
Spiral Car The Spiral Car is the third variety of the dragster. Equally upgraded in all stats with an additional expansion slot. Needs modifications for acceptable performance on dirt and ice. Very high to expert mechanic needed for best build.

Open Wheel
Wing Car The Wing Car is the entry level open wheel car. Exchanging acceleration for control. In basic form, best used on asphalt. Unlockable by winning Japan GP. Upgrade 50% to unlock The Sonic Car.
Sonic Car The Sonic Car is an upgraded Wing Car. Greatly improves on the weak acceleration of the Wing Car, also not an ideal car for dirt and ice. Requires a good mechanic for optimal build. Upgrade 50% to unlock Aero Car.
Aero Car The Aero Car is the final form of the Wing Car. Highest default handling of the basic car bodies with moderate upgrades in durability and speed over the Sonic Car. Additional add-on slot. Very good to expert mechanic needed for optimal build.

Special
The Banana Car has modest stats but earns data and experience very quickly. Can be created in a New Game plus as the first car, albeit with very humble performance. Unlockable by placing first in the Chimp Island GP.
Duck Car Duck Car. Maximize ad revenue while driving a duck. Unlockable by completing Autoburg Sponsorship.
The SL is a steam locomotive, exchanging any attempts at handling for raw acceleration and durability. Not suitable for dirt, but modest performance on ice. Unlockable by completing Kairo Insurance Sponsorship.
The Kairo Kar is a laughably fragile vehicle that will not even survive a lap around any track without significa upgrades. Even still, it's incredibly powerful and dirt cheap. S Rank! Unlockable by winning the Kairo Island GP.
Mach Car, an obvious riff on Speed Racer. Posses no real weak point save for its difficult in construction and poor performance on dirt and ice. Unlockable by upgrading both the Spiral Car and the Aero Car to 50% each.

Special Characters

Add Ons

Each car will have a pre-determined number of 'slots' for tech add-ons. These add-ons will improve stats, give bonuses and features to cars that normally wouldn't have them (i.e. ice driving). All add-ons have a rank (the difficulty associated with installing them) as well as a deployment cost (the price to add to your car). Additional technology is usually available by winning races, pleasing sponsors or upgrading existing technology beyond 80%.

Sponsors

Sponsors play a vital role in acquiring funds as well as unlocking special parts for your cars. In general, a sponsor will have a target that they wish to reach. They will pay you a semi-yearly revenue, plus bonus if you do well. Once they reach their target they will give you a reward and introduce you to a new sponsor. Higher race finishes as well as a driver with good appeal will please sponsors faster.

Errors

After clearing Mocha Cola you're informed you can now research Hyper Oil, but Car Camera appears in the research list. However researching "Car Camera" will give you the Hyper Oil item.

The same is true after completing Cheapy P's, who give you Car Camera which appears as Hyper Oil in the research list.
