Last year my ex wife bought a new Toyota Yaris and it was like a little Dream Car for her, though she said it is a bit sluggish off the mark. (auto) So I sent her specs I googled on the new Performance version: Toyota GR Yaris Breaks Cover With 257 Horsepower, All-Wheel Drive ! It has the world's most powerful three-cylinder engine installed in a road car. The Yaris hasn’t exactly been the most exciting car in its segment, but Toyota changed opinion about the supermini, with the performance GR model.
