With a sharp knife, lightly score both sides of steak in a crisscross pattern. Place steak in a large ziplock bag.
In a medium bowl, combine teriyaki sauce, cola, onion, garlic, vinegar, oil and hot sauce, whisking well to combine. Reserve 1/2 cup of marinade. Pour remaining marinade over steak in ziplock bag, seal bag and turn over a few times to thoroughly coat. Refrigerate for 2 hours.
Preheat broiler and place a rack 3 inches from heat source. Let steak and marinade sit at room temperature for 15 minutes. Remove steak from bag; discard excess marinade. Season steak on both sides with salt and pepper. Place steak on a broiler pan and broil for 6 minutes. Turn steak, brush with reserved marinade and broil for 6 minutes longer (for medium rare).
Remove steak to a cutting board, tent with foil to keep warm and allow to rest for 10 minutes. Carve steak into thin slices and serve.
