Following the immense success of the rally-inspired GR Yaris overseas, Toyota’s Gazoo Racing division needed an offering for the North American market. After years of workβ€”including delays brought on by Toyota CEO Akio Toyoda, who wasn’t initially satisfied with the prototypeβ€”their result was the Toyota 2023 GR Corolla. Sharing the unique 1.6 liter three-cylinder G16E-GTS engine with the GR Yaris, the GR Corolla puts out an impressive 300 horsepower and 273lb-ft of torque.

So, what does having one of the most powerful three-cylinder engines in history mean? Well, it means you’re in for a lot of fun. But it also means when you’re driving hard, you’ve got to keep that straight-three engine cool. That’s why we’ve been hard at work developing the aluminum Performance Radiator for the 2023+ Toyota GR Corolla.
