Toyota replaces 1.33-liter engine in Yaris with more efficient 1.5-liter unit

Here is good news for those planning to purchase a new Toyota Yaris in Europe – a new powerplant is on the way. This new engine will be more powerful – with more output and more torque – than the powerplant that it is replacing.

Soon to be gone from the Toyota Yaris will be the current 1.33-liter 16-valve DOHC Dual VVT-i engine that slots above the 1.0-liter entry-level powerplant. With a displacement of 1,329 cc, this engine is able to deliver up to 99 hp of output and up to 125 Nm of torque available at 4,000 rpm. When paired to a six-speed manual transmission, the 1.33-liter Dual VVT-i petrol engine consumes just 4.9 liters of fuel per 100 km (combined). When mated to a continuously variable transmission (CVT), this 1.33-liter engine eats up 5.1 liters of fuel per 100 km (combined). In combined driving, this powerplant only emits 114 grams of carbon dioxide per kilometer, both when paired to either the manual gearbox or the CVT.

In terms of performance, the 1.33-liter Dual VVT-i engine allows the Toyota Yaris subcompact car to accelerate from zero to 100 kilometers per hour (62 mph) in around 11.7 seconds for the manual version and 12.6 seconds for the CVT version of the subcompact.

While already dynamic and boasting of low fuel consumption and low carbon dioxide emission levels, the 1.33-liter engine will be out soon. This is primarily because of the need to fit the Toyota Yaris with a powerplant that could comply with the future Euro 6c emissions standard as well as with Real Driving Emission (RDE) homologation requirements. Thus, in anticipation of these future requirements, Toyota commenced the development of a new engine that would replace the current 1.33-liter petrol engine. The development of the new engine – with a higher displacement of 1.5 liters – was of €150 million ($161 million) in investments made by the Japanese carmaker. This new 1.5-liter engine – produced by Toyota Motor Industries Poland – is now compliant with both the Euro 6c and RDE measures while delivering more output and more torque.

In terms of power, the new 1.5-liter engine is able to develop 108 hp (110 PS) of max output and 136 Nm (100 lb.-ft.) of peak torque available at 4,400 rpm. With this amount of power, a Toyota Yaris equipped with this new engine could sprint from standstill to 100 km/h (62 mph) in around 11.0 seconds, when the powerplant is paired to a manual transmission.

Aside from the higher levels of output and torque, the new 1.5-liter mill is also friendlier with the environment. This new 1.5-liter engine is expected to boast of 12-percent better fuel economy and lower carbon dioxide emissions than the 1.33-liter powerplant that it is replacing. This is thanks to the employment of a water-cooled exhaust manifold that helps restrict the gas temperature.
