Hot on the heels of the introduction of the new Scion iM at the New York Auto Show last week, we learn today that a turbocharged gas engine has found its way into the parent company’s Toyota Auris counterpart for Japan. The new turbo is also on tap for the European Auris later this year.
Toyota says the refreshed Auris with its new turbo engine plus a new safety package went on sale in Japan today. This latest redesign “advances the Auris brand by building on the individuality and performance that has defined the model since its first generation.” In addition, Toyota has combined the best of the model’s new features by creating the high-end 120T grade.
The 120T comes with Toyota’s newly developed 1.2-liter direct-injection turbo engine (8NR-FTS), and also offers an extensive range of comfort and convenience features. This small displacement engine puts out 85kW (116ps) and 185Nm (18.9 Kgf-m) of torque. Instead of flat-out performance, this engine is designed for economical operation and low emissions.
The engine pairs a single-scroll turbocharger with a cylinder head that uses an integrated water-cooled exhaust manifold to optimize exhaust temperature. This enables adaptive intake cooling that is not affected by the engine’s thermal load. The result is said to be responsive acceleration and maximum torque across a wide rpm range.
Toyota says it has also improved combustion speed by creating a strong tumble flow (a vertically-rotating swirl) inside the cylinder. This, together with advanced D-4T technology, creates an ideal air-fuel mixture. In addition, continuous variable valve timing on the intake (VVT-iW) allows the engine to use the Atkinson cycle by adjusting valve timing according to load. These improvements combine to produce maximum thermal efficiency of 36 percent, a “leading level among mass-produced gasoline engines.”
Peak torque is generated at a wide range of rpms between 1,500 rpm and 4,000 rpm. This, combined with Super CVT-i adjusted to bring out the best in the turbo engine, is designed to for responsive acceleration and smooth, performance.
Thermal efficiency has been improved by using an exhaust manifold integrated with the cylinder head, a larger variable angle VVT-iW (intake side), and an advanced D-4T fuel injection system. Additionally, the Stop & Start idling-stop function improves fuel efficiency.
At 19.4 km/L, fuel efficiency exceeds the Japanese government’s 2015 fuel economy standards (as specified in the Act on the Rational Use of Energy) by at least 10 percent. Additionally, emissions are at least 75 percent lower than the 2005 standards set under the Japanese government’s Approval System for Low-emission Vehicles. As a result, the 120T grade is eligible for the Japanese government’s subsidies and tax incentives for eco-cars.
Standard Auris 120T features include a specially designed instrument panel with wood-grain finish, and seat fabric made from a combination of Ultra-suede leather and artificial leather for a smooth feel. Driver experience is further enhanced with other features such as cruise control, heated driver and passenger seats, and an auto anti-glare inside rear view mirror.
As part of Toyota’s multi-faceted approach to support safety on the road, the recently-announced Safety Sense C package uses both a laser radar unit and a camera to achieve reliability and performance. The package comes standard on 1.2-liter turbo and 1.8-liter models, and is available as an option on 1.5-liter models.
Pre-Collision System (PCS) uses a camera and laser radar to detect objects ahead of the vehicle, and when there is a possibility of collision it prompts the driver to brake with an audio and visual alert. If the driver fails to brake in time, the system automatically applies the brakes, reducing speed by approximately 30 km/h to help prevent or mitigate the collision. The operational range of PCS covers speeds at which at least 80 percent of rear-end collisions occur (i.e. relative speeds of between approximately 10 km/h and 80 km/h).
Lane Departure Alert (LDA) uses a camera to detect white and yellow lane markings. If the vehicle starts to deviate from the lane, LDA alerts the driver with an audio and visual alert.
Automatic High Beam (AHB) helps ensure excellent forward visibility during nighttime driving. It uses a camera to detect the headlights of oncoming vehicles and the taillights of vehicles ahead, and then automatically switches between high beams and low beams so as not to interfere with the vision of other drivers.
A newly added special function alerts drivers with an audio and visual alert when preceding vehicles have started to move after waiting at a traffic signal. This is a standard feature on 1.2-liter turbo and 1.8-liter models, and is available as an option on 1.5-liter models.
