Nice shots, and not too dark! A word of advice, try not to center your shots strait at the car. for instance, on your third shot, try zooming out and panning to the right a little, to give it a greater sense of action. Also, play around with the focus and such. Using your third picture as an example again, place your focus near the bottom right corner, hit square to use the focus, and lower the shutter speed. That will give it a higher sense of speed.
Utilize these techniques for your next update, and it should be outstanding.
Possibly after your Nissan update, do an American muscle car one. 💡
