Sonic test-drive a certain race car
(Art have been glazed)
The context: Tails borrowed that race car from Dodon Pa and had Sonic test-drive it, and he's not amused that Sonic's stressed the car's engine by abusing the boost-pod function (which temporarily ionizes and compresses air intake and boosts the engine power, but at the risk of engine blow).
The car in question is the Nu-Asurada AFK-0 from Future GPX Cyber Formula anime series, except it's white-colored. Double as a voice actor joke, as Jun'ichi Kanemaru (the JP voice of Sonic) voiced Hayato Kazami in that anime series.
