Mazda6 engine light may illuminate due to reasons such as poor mixture combustion, sensor issues, maintenance problems, or fuel quality problems. It is recommended to seek professional repair at a specialized service center. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, and more. The Mazda6 has a body length, width, and height of 4670mm, 1780mm, and 1435mm respectively, with a wheelbase of 2675mm. The Mazda6's front bumper and chrome-plated winged grille adopt Mazda's coupe-style design, and the door side moldings have been removed.
