The opposition were no match for the unbeaten four-year-old, dubbed the Usain Bolt of horse racing, as he pulled away from the pack to stroll to his 11th win in 11 races.
Frankel, a 1-10 favourite ridden by Tom Queally, finished ahead of Excelebration (5-1). Side Glance (33-1) was third.
"I'm not surprised Frankel won but I am relieved as no horse is a certainty," trainer Henry Cecil told the BBC.
"He's a great, great horse. He did exactly what I thought but he is still improving.
"We will leave our options open now. He will tell me what to do, I don't tell him. Will he go abroad? It's very unlikely," added Cecil.
