The potential transfer of the Toyota GR Corolla’s turbo-three engine to a Lexus

The turbocharged, 1.6-liter three-cylinder engine first seen in the rally-inspired GR Yaris and also utilized in the GR Corolla may potentially be included in a Lexus model. The brand showcased this engine in a concept car earlier in 2024, and recent reports suggest that this model is set for production.

If you’re unfamiliar with the LBX name, it refers to a compact crossover based on the Yaris Cross that was revealed in 2023 and created for international markets, excluding the United States. While the standard model lacks a sporty flair, Lexus delved into the idea of a more performance-focused version with the LBX Morizo RR concept introduced at the 2024 Tokyo auto show.

This concept, featuring a refined version of the turbocharged three-cylinder engine from the Yaris and Corolla, may soon be produced. According to John Pappas, CEO of Lexus Australia, a production model of the Morizo RR is likely but not yet confirmed. Toyota chairman Akio Toyoda, who reportedly drives the concept personally, also hinted at a potential production model in a promotional video.

The Morizo RR boasts a unique version of the turbo-three engine, producing 305 horsepower and 295 pound-feet of torque. Contrastingly, the GR Corolla offers a similar power output but with 273 pound-feet of torque, while the updated GR Yaris provides figures of 280 horsepower and 287 pound-feet of torque. The reason for the power variance remains unclear. The concept includes all-wheel-drive and an eight-speed automatic transmission, with uncertainty regarding the potential inclusion of a six-speed manual in the production model.

Additionally, the Morizo RR concept features suspension enhancements, high-performance tires, and a more aggressive body kit, distinguishing it from the standard LBX model. The overall design appears plausible and realistic, rather than an overly futuristic concept unlikely to hit showroom floors anytime soon.

If the Morizo RR concept proceeds to production, more details are expected to emerge in the upcoming months. While there is no indication of the crossover being available in the US, where the standard LBX is not offered, it remains intriguing to see if the 1.6-liter engine could be utilized in other Lexus models developed for the American market.
