The Supra was offered with a 2.0 L 12-valve SOHC inline-six engine (M-EU, chassis code MA45) or the 2.6-liter 12-valve SOHC inline-six engine (4M-E, chassis code MA46). The Japanese model was equipped with the smaller 2.0 L engine so that buyers would not incur an additional tax under vehicle size and engine displacement regulations. Both engines were equipped with electronic fuel injection. The installation of the larger engine did obligate Japanese buyers to pay a higher annual road tax, making owning the car more expensive than the smaller Celica.
