The TToyota Yaris GR It broke our schemes in every way. On the one hand, never before has a compact of its size behaved like the GR Yaris and never before has Toyota put so much meat on the grill.
Sitting at the top of the new Yaris range, the GR Yaris is a unique model that benefits from the technical and design skills of TOYOTA GAZOO Racing and Tommi Mäkinen Racing, Toyota’s WRC partner. In addition to being the official homologation model for the development of the next Yaris WRC, the new GR Yaris also has all the attributes that owners are looking for to compete successfully in local rally competitions.
The lower roofline improved the capacity of the GR Yaris to cut the air, while the placement of the new 1.6 turbo engine further back, near the center of the structure, and the battery in the trunk, helped to achieve a better balance of the chassis and, with it, better driving feel , stability and response.
The three-door body is made from lightweight materials such as carbon fiber polymer and aluminum to achieve an impressive power-to-weight ratio, while the new platform allows for a wider rear track and a new rear suspension system. double triangle. Reinforcements have also been introduced under the side bars to ensure maximum suspension performance.
Although the new GR Yaris sits at the top of the new Yaris range, it features a unique design, with a three-door body and a 91mm lower roof, which forms a coupe-like silhouette, intensified by the rear doors. Frameless. At the front, the grille design and lower molding express the true GR status of the new GR Yaris, while the wide rear and powerful wings accommodate 18-inch alloy wheels.
The GR Yaris’s engine is a new turbocharged three-cylinder unit with innovations such as multi-oil-injected piston cooling, large-diameter exhaust valves and a machined intake port. With a displacement of 1,618 cm3, it develops a maximum of 192 kW / 261 hp and 360 Nm of torque.
The compact and lightweight DOHC 12-valve engine is mated to a six-speed manual transmission designed to match its high levels of torque.
The body is predominantly constructed from lightweight materials, such as a new carbon fiber polymer for the roof, which can be compression molded. Aluminum is used on the hood, doors and tailgate.
As a result, the GR Yaris has the power of a C-segment high-performance sports car, but the weight of a B-segment model —tare of 1,280 kg—. Its power-to-weight ratio of just 4.9kg/hp helps achieve 0-100km/h acceleration in less than 5.5 seconds and an electronically limited top speed of 230km/h.
The performance of the GR Yaris is based on a new GR-FOUR four-wheel drive system, designed to optimize the power distributed to each wheel, as well as being simple and light.
Torque distribution between the front and rear axles is regulated by a highly responsive coupling. As an option on the Circuit Pack, two Torsen-type limited-slip differentials manage the distribution between the left and right wheels, to offer natural and direct control of the vehicle.
Now, thanks to Akrapovič, homeowners will be able to purchase the Slip-On Race Line Titanium and the Evolution Link Pipe SS.
The sound will be managed by two megaphone-shaped titanium tailpipes which are specially coated to resist any color change at high temperatures.
three resonators further refine the sound experience to create a sporty racing tone, fully enhancing the character of the engine with a deep, enthusiastic sound.
Like all good exhausts, the technical data is modified and the complete exhaust system produces power gains of 13.5 kW (18 hp) at 5,900 rpm and torque increases of 21.8 Nm at 5,900 rpm – as well as a interesting weight saving of 5.6 kg-.
Not bad, right?
