Four different prototypes, each based on the US market Elantra GT were spied testing in the US this week alongside a convoy of Prius models.
The four Elantras all had different bodies, suggesting Hyundai is working out the most aerodynamic Prius-style shape for its upcoming hybrid. Both the standard five-seat Prius and the seven-seat Prius+ were part of the convoy, suggesting Hyundai will offer two differently-sized hybrid models.
There were no charging points on the cars, suggesting a parallel hybrid rather than a plug-in setup.
Hyundai first previewed its intention to take on the Prius with its 2010 Blue-Will concept. The Blue-Will concept was powered by a 1.6-litre direct-injection petol engine in conjunction with a 134bhp electric motor.
