The Toyota Aygo is built on the successful GA-B platform of the Toyota Global New Architecture (TNGA), first introduced with the new Yaris—the current Car of the Year 2021 in Europe—and more recently with the Yaris Cross.
At 3,700mm in length, the new Aygo X is 235mm longer than its predecessor, although the wheelbase is increased by just 90mm. The front overhang is 72mm less than Yaris, while maximum wheel size is increased to 18”.
