Choose the right racer for the right track. Here's the quick overview on each of the available vehicles witch you can customize as you level up!:
Buffalo 46-TR - Handling: 4 Acceleration: 7 Speed: 4
The car you start off in, you'll want to upgrade to the next vehicle as soon as possible, so go for clean laps, grab that extra XP and level up to Apprentice as soon as possible.
Yugana SB-23 - Handling: 5 Acceleration: 5 Speed: 6
It might take a little while to get going, compared to the Buffalo 46-TR, but for tracks with good straights and minimal cornering this beauty will get you well on your way to finishing off the challenges.
Loewenmech X3-53 - Handling: 4 Acceleration: 5 Speed: 7
Another vehicle that favors raw speed over a quick start, the Loewenmech is a decent upgrade once you've achieved Engineer rank.
Protagonist TI33 - Handling: 7 Acceleration: 5 Speed: 4
A rather sluggish, yet agile craft, the Protagonist is unlocked once you hit the rank of Senior Engineer.
Nousagi RS-55 - Handling: 7 Acceleration: 5 Speed: 6
If you favor taking sharp corners at blistering speeds, upgrade to the Nousagi RS-55 once you've achieved Expert rank.
Berserkur 4582 - Handling: 5 Acceleration: 6 Speed: 7
The last vehicle, and it's unlocked when you hit Veteran level. The best all-rounder you can get your hands on.
