Three modified American muscle cars go head-to-head in the UK — a tuned 770-horsepower Camaro ZL1, a stock 808-horsepower Hellcat Redeye, and an 859-horsepower Mustang saddled with the only manual gearbox in the fight. Carwow’s drag race has racked up nearly 14 million views, largely because of how close the supposedly disadvantaged stick-shift car gets. Watch the full run to see if horsepower or gearbox wins out.
