Introduction:

Toyota has once again proven its prowess in producing high-performance cars with the introduction of the GR Corolla and GR Yaris. These models are touted for their excellence in engineering, design, and performance, as they were developed under Toyota’s Gazoo Racing (GR) division. In this article, we will explore the process of how Toyota builds these impressive machines.

Design Process:

The creation of the GR Corolla and GR Yaris starts with a vision from the Gazoo Racing team, which works closely with Toyota’s design division. This collaboration is essential in ensuring that both vehicles strike a balance between practicality and performance.

Developing the Chassis:

Both the GR Corolla and GR Yaris have a unique platform designed to accommodate high-performance components. Toyota engineers focus on developing a rigid structure, which utilizes high-strength materials and robust welding techniques. This results in a platform that offers excellent rigidity while managing weight effectively.

Powertrains:

Toyota equips both models with state-of-the-art powerplants that deliver exceptional performance while maintaining reliability. The 1.6-liter turbocharged three-cylinder engine powers the GR Yaris, producing an impressive 268 horsepower and 273 lb-ft of torque. On the other hand, the larger 2.4 L Inline-4 engine is likely to be placed under the hood of GR Corolla delivering close to 300 horsepower.

Transmission:

The power produced by these engines is transmitted through highly efficient and advanced drivetrains. The GR Yaris benefits from a 6-speed manual transmission equipped with a limited-slip differential for optimal power delivery to all four wheels.

Similarly, the GR Corolla also boasts a manual transmission to cater to driving enthusiasts’ preferences.

Suspension Systems:

One key aspect of any performance-oriented vehicle is its suspension system. Both models feature sophisticated suspension setups that use MacPherson struts in the front and double-wishbone rear suspension. This design allows for maximum grip and control, particularly during high-speed driving and cornering.

Aerodynamics & Weight Reduction:

Aerodynamics play a crucial role in the performance of the GR Corolla and GR Yaris. Toyota uses extensive aerodynamic research to optimize both models’ bodies for maximum downforce and minimal drag. Weight reduction is also a priority, with the use of lightweight materials like carbon fiber reinforced plastics (CFRP), aluminum, and high-tensile steel.

Quality Control & Testing:

Once the components and subassemblies are manufactured, they undergo several stages of quality control checks. Additionally, both the GR Corolla and GR Yaris are subjected to rigorous testing at various racetracks, including the renowned Nürburgring circuit. This helps Toyota ensure that its vehicles meet stringent performance standards before being released to the public.

Conclusion:

The GR Corolla and GR Yaris are prime examples of Toyota’s commitment to producing high-performance vehicles under their Gazoo Racing division. From design concept to production, careful planning and attention to detail are evident throughout every aspect of these cars, resulting in truly remarkable machines that continue to push the boundaries of automotive performance.
