These two old and very popular models, eclipse GST and GSX, have their full meaning as Grand Sport Turbo and Grand Sport X, respectively. These two models are actually similar in their engines and styling, but the major difference between them is their transmission layout. If you drive the eclipse GST, you will find out that you can only use the wheels at the front to propel the vehicle; this is simply because it is a front-wheel vehicle.
On the other hand, if you drive the eclipse GSX, you will notice that the power of the vehicle is transferred to all the four wheels. This is simply because the GSX is a four-wheel-drive vehicle. Hence, the eclipse GST is characterized by all the features you can find in a front-wheel-drive (FWD) vehicle or engine.
Also, the eclipse GSX is characterized by all the features you can find in a four-wheel drive (4WD) vehicle or engine.
