2017 Toyota Yaris getting new 1.5-liter petrol engine image

The usually mundane Yaris has had a great period lately – last December the WRC version came out, this month the official road-going motorsport inspired model also became official and there was even a leak with its facelift in Japan.

The WRC-inspired Yaris features “more than 210 horsepower (156 kilowatts)” and shows early cues of the facelift that is surely coming, and we now know the refreshed model will also feature a new 1.5-liter, naturally-aspirated engine in its standard version. The new unit is coming to replace the 1.33-liter unit in use today, coming with increased power and fuel economy. It will offer 110 hp (82 kW), which is 12 hp (9 kW) above the current one, and also a peak torque of 101 pound-feet (138 Newton meters).

The Yaris has always been slightly geared towards the European market, and the new engine is even produced in n Poland as part of a $161-million investment, coming with “better performance and a more enjoyable drive,” but it’s also 12 percent more fuel efficient, according to the NEDC tests. The new Yaris 1.5 will sprint to 62 mph in exactly 11 seconds, which is almost a second better than the old one, and also made the switch from the Otto to the Atkinson cycle to “gain optimum efficiency in different driving conditions,” coming with a 38.5 percent thermal efficiency value, “among the best on the market.”
