This year’s Yaris WRC cars feature improved aerodynamics, with increased front downforce and a better overall aerodynamic balance courtesy of a new bumper and guard package.

The updated cooling system might not be a factor in early rounds held during the northern hemisphere winter, but should come into play in later rounds, including the final round at Coffs Harbour in November.

Strengthening the driver line-up is Estonia's two-time WRC event winner Ott Tänak, who joins Jari-Matti Latvala and Esapekka Lappi.

Toyota's return to world rallying with the Yaris last year saw it finish third in the manufacturer championship, with Latvala fourth in the drivers' standings.

Team principal and rally legend Tommi Mäkinen said the team is ready to build on its solid debut season.

"We saw last year that the Toyota Yaris WRC was already capable of winning rallies," he said.

"This was a great achievement by the team, but the competition also allowed us to discover areas where we can improve.

"With more time and learning, we have been able to update the aerodynamics and improve the engine cooling.

"I'm very excited that we're going to keep learning this year, as part of our mission to make ever-better cars."
