New Toyota Yaris marks first use of TNGA for compact; new hybrid system



In Japan, Toyota Motor Corporation (Toyota) unveiled the new Yaris model. Scheduled to go on sale in Japan starting in mid-February 2020, the new Yaris will be exhibited at VenusFort in Odaiba, Tokyo during the Tokyo Motor Show 2019. The new Yaris will also be on display in showrooms throughout Japan from the end of October to December.

The first-generation Yaris was created in 1999 to serve as a global standard for compact cars by listing Toyota's full portfolio of technology. Toyota has redesigned the platform and all major components, including the engine, transmission, and suspension to achieve generous cabin space and outstanding basic performance in a minimal size.

The new Yaris is a new-generation compact car that adopts Toyota's New Global Architecture (TNGA) platform, on which Toyota will base its compact cars for developing countries in the future, and features components built entirely from the ground up, including the engine , Hybrid System, transmission, and suspension.

In addition to the light yet highly rigid body and low center of gravity, the Yaris is offered with four different powertrains to deliver agility, superior comfort, and smooth and direct acceleration:

  • The newly developed 1.5-liter inline three-cylinder Dynamic Force Engine and Direct Shift-CVT;

  • The 1.5-liter Dynamic Force Engine with New-generation Hybrid System;

  • The 1.5-liter Dynamic Force Engine with 6-speed manual; and

  • An improved 1.0-liter engine with a compact and lightweight CVT.

In addition to pursuing Toyota's ongoing goal of developing the world's highest fuel efficiency for a hybrid vehicle, the new Yaris is offered with the E-Four (electric four-wheel drive system), a first for a compact Toyota car.

Toyota is among the first to adopt an array of advanced features challenging the common hierarchy based on car size, such as Advanced Park, Toyota's advanced parking support system (a first for a Toyota vehicle); the latest Toyota Safety Sense, which has been expanded to detect oncoming cars when turning right at an intersection and pedestrians crossing the street when turning right or left; Turn Tilt Seats (equipped by Toyota for the first time) which facilitates entry and exit of the vehicle; and Display Audio (standard on all models), which can connect to smartphones.

An accessory power outlet (1,500 W) is available for the hybrid version of the cars. With the accessory, electricity from the vehicle can be used to power electrical appliances and appliances using the same type of electrical outlets found at home. Additionally, the vehicle can serve as an emergency power generator in cases such as blackouts.

This marks the 20th year since the first Yaris debuted, so we wanted to build a new-generation compact car that goes far beyond customers' preconceptions about building a class on the strengths of the Yaris as a compact car while revamping the platform, powertrain, and all other components . Compact cars are driven by many, so offering a pleasurable drive was a priority, but it also prompted us to use the Yaris as the starting point of cars with the world's highest level of fuel efficiency and secure safety technology.

TNGA for compact cars. The new Yaris model is Toyota's first car to adopt the GA-B platform for compact cars, which features a body developed to be lightweight and highly rigid with a low center of gravity. The platform achieves both superior handling stability and a high-quality ride by shedding 50 kg in vehicle weight compared to the conventional model, increasing torsional rigidity by at least 30%, and lowering the center of gravity by 15 mm. It also delivers driving performance beyond its class by being agile yet confident and natural (the vehicle remains stable while driving naturally responsive to driver's intentions).

TNGA platform for compact cars


The newly developed 1.5-liter inline three-cylinder Dynamic Force Engine is based on TNGA design philosophy. This engine uses high speed combustion technology, such as a longer stroke and expanded valve angle to achieve both low fuel consumption and high output.

Toyota also enhanced the 1.0-liter inline three-cylinder engine through various improvements that include increased tumble flow, higher EGR (exhaust gas recirculation) rate, and reduced friction to achieve nimble driving and lower fuel consumption.

1.0-liter engine and Super CVT-I


The new generation 1.5-liter Hybrid System (adopted by Toyota for the first time) achieves greater fuel efficiency by enhancing the efficiency of the entire system and by adopting a dedicated engine designed for the Hybrid System and other newly developed hybrid units.

Advanced features for safety, security, comfort, and convenience. The new Yaris comes standard with Toyota Safety Sense, Toyota's latest active safety package.

The pre-collision safety system detects pedestrians during the day and night and cyclists during the day to help prevent collisions and mitigate damage. The sensing system has been expanded to prevent accidents at intersections by detecting oncoming cars when turning right and pedestrians crossing the street when turning right or left (adopted by Toyota for the first time).

Toyota also added Low Speed ​​Acceleration Control (adopted by Toyota for the first time) to support the prevention of collisions caused by pedal misapplication at reduced speeds. This uses millimeter-wave radar and a mono camera to detect bicycle riders and pedestrians immediately in front of the car. This control helps prevent collisions and mitigate damage by suppressing the engine output or lightly applying brakes to suppress acceleration if there is an object in front of the car and the accelerator pedal is depressed with excessive force when starting from a standstill or during low- speed operation.

Yaris also features:

  • Dynamic Radar Cruise Control with full-speed range that supports driving behind another car;

  • Lane Tracing Assist (LTA that enhances steering so cars can remain centered on the same lane when using radar cruise control;

  • Automatic High Beam (AHB) that switches between high beam and low beam headlights; and

  • Road Sign Assist (RSA) that displays road signs recognized by the camera on the display so drivers do not miss them.

The new Yaris is also equipped with a Secondary Collision Brake, which contributes to mitigate the damage caused by secondary collisions. The Secondary Collision Brake and brake lights are automatically activated if the SRS air bag sensor detects a collision and activates the air bags. This decelerates the vehicle to mitigate damage caused by secondary collisions.

For the first time, Toyota is introducing Advanced Park, which represents the cutting edge of Toyota's Advanced Parking Support System and is based on Toyota's automation concept of having the car and driver act as partners.

This system supports parking operations by controlling not only the steering wheel but also the accelerator and brakes (the driver only needs to operate the shift lever according to the instructions). The system alerts the driver with audible warnings and uses the brakes to help avoid minor collisions by using cameras and ultrasonic sensors to monitor the car's vicinity.

By setting the parking spot in advance, the system can also park in spots without white lines — a world first.
