According to reports, Toyota is working on an upgraded version of its popular Yaris GR. Trusted Japanese magazine Best Car has revealed that the high-performance subcompact hatchback will be introduced this fall with a more powerful engine and some styling enhancements. The production is expected to begin early next year.

Sources close to Toyota have informed Best Car that the turbocharged 1.6-liter engine will receive modifications to deliver an impressive 300 horsepower with a torque rating of 272 pound-feet (370 Newton-meters). This gives it a 28-hp advantage over the Yaris GRMN introduced earlier this year as a limited edition model exclusively in Japan, where only 500 units were made available. However, the rumored GR Yaris would have slightly less torque, with a decrease of 15 lb-ft (20 Nm), compared to the full-powered GRMN which boasted 287 lb-ft (390 Nm).
