Brad Keselowski says every race is still big for the NASCAR Sprint Cup series and its new car.

The defending Cup champion says there have been compelling racing and great battles so far this season even though teams haven't fully developed the new models that look more like their passenger car counterparts.

The next test for the new cars is at Texas, the high-banked 1 1/2-mile track where the first night race of the season will be Saturday night. It also is where testing was held last fall that NASCAR officials say was one of the pivotal moments in the development of the car.

Robin Pemberton, NASCAR vice president of competition, said Thursday that teams seem pretty happy with the package they've been given to start the season.
