Developed in partnership with Citroen and Peugeot and launched alongside the C1 and 107 (later renamed the 108), the Toyota Aygo needed just a few years to become one of the most appreciated vehicles on the mini car market. Praised for its bold styling, agile handling, peppy three-cylinder engine, and rock-solid reliability, the Aygo is among the most popular of small hatchbacks in Europe. Redesigned in 2014, the second-generation Aygo received its mid-cycle facelift at the 2018 Geneva Motor Show.

The first-generation Aygo was launched with two small-displacement engines. The gasoline option was a 1.0-liter three-cylinder rated at 67 horsepower and 69 pound-feet of torque, while the diesel version used a 1.4-liter four-cylinder with 54 horses and 96 pound-feet. The redesign from 2014 saw Toyota drop the diesel and add a 1.2-liter gasoline unit from PSA instead. The 1.0-liter mill, shared with many other Toyota models, as well as the Citroen C1 and Peugeot 108, continued with certain upgrades.
