High fuel efficiency at the same time as an exhilarating driving sensation-this is the result of coordination between the engine, which is sometimes called the heart of the car, and the drive train, which transmits the power generated by the engine to the tires.
Engine combustion technologies have been intensively applied to maximize thermal efficiency and improve fuel efficiency.
The engine boasts further evolution in improved combustion and loss reduction technology. By also incorporating hybrid vehicle technology, it delivers fuel efficiency at the same time as driving performance.
Designed for a small vehicle size, the engine combines direct injection with a turbocharger to provide compact dimensions. In this way, it delivers both fuel efficiency and a brisk driving style.
Designed for a large vehicle size, the engine combines direct injection with a turbocharger to provide compact dimensions. With the added advantage of port injection, it delivers both fuel efficiency and high-quality driving performance.
Innovations in combustion have achieved high thermal efficiency, low noise, low emissions, and high performance, delivering a quietness that belies the diesel engine along with powerful driving performance.
The drive train technology offers power management, which maximizes engine performance, and improved transmission efficiency, which conveys that power to the tires without wastage, contributing to improved fuel efficiency.
Widening of the gear ratio range to exploit the engine's region of high efficiency plus improved transmission efficiency deliver a responsive driving performance combined at a high level with outstanding fuel efficiency.
The multi-speed transmission, with its wide and close gear ratio, and use of comprehensive friction-reducing measures deliver outstanding fuel efficiency and exciting driving performance.
Toyota will continue to evolve gasoline/diesel vehicle technology to drive the further widespread adoption of eco-cars.
