Toyota has developed a 2.0-litre engine that it claims is the most thermally efficient gasoline unit in production.
The new four-cylinder engine is said to have a thermal efficiency of 40% â€“ 1%, short of what the Toyota Prius offers with its 1.8-liter hybrid powertrain.
Toyota has said the engine can reach unprecedented levels of fuel economy, because of friction, reducing technology and more efficient exhaust and cooling systems.
Will be implemented through the Toyota new global architecture (TNGA) models in the coming years.

The new 2.0-litre petrol engine will also be available with hybrid electric power. In this capacity, to adapt to the Prius 41% thermal efficiency, but provides the best performance thanks to its larger capacity. The peak power to 169bhp and torque of 128lb ft.
This hybrid powertrain is expected to be introduced via the upcoming Auris, which is scheduled for unveiling at the Geneva motor show next week.
It will be one of two hybrid powertrains offered in the new Auris, with the existing version of the 1.8-liter hybrid powertrain remaining as the entry point, although in an updated form.
Expanded hybrid line-up made with the new 2.0-litre engine should, in part, to fill the gap left by the parties, the diesel Auris. Toyota dropped the diesel version of the Auris last year and a half the demand is low, with only 651 units sold in 2017.

Toyota has also developed a more efficient CVT gearbox that uses the world’s first gear for initial acceleration. This essentially gives the exchange the fastest off-the-line response of a standard automatic, but it also allows for the increased efficiency of a CVT during the movement.
In the meantime, Toyota has created a torque vectoring system for the petrol all-wheel-drive models that can separate the front axle for pure rear-wheel drive. This system will be introduced in Toyota’s all-wheel-drive and off-road models in the near future, with claims of improved fuel economy.
Toyota new technology comes at a time when it comes to making big changes in the UNITED kingdom. The Japanese automaker looks set to replace its low-selling Avensis sedan with a new model Corolla.
Even if it has not been available in Britain for 11 years, the Corolla has been sold in other markets, such as in a saloon. The new car will have a strong technical links to the Auris, using the same base and engines.
