Toyota’s hot-hatch GR Corolla is a three-cylinder oddity that is very appealing to enthusiasts. In this full review we take a deep dive into the GR Corolla and also compare it to another odd-cylinder-count fun-to-drive car…the Audi TT RS. But wait, there’s more! We also spent time with Ford’s Bronco Raptor and with the help of the boys from Sons of Speed, we took the GR Corolla to our super secret testing facility for another race to see how these two unique offerings would fare.
