PSA Peugeot Citroen has developed its Hybrid4, previously called HYmotion4, which is planned for initial use in the Peugeot 3008 crossover to appear in 2011. As an example of the versatility of this parallel hybrid architecture, Peugeot recently displayed the striking Peugeot SR1 ‘Grand Touring Car.’ The SR1 is a 2+1 coupe with third passenger seat located between two front seats. Entry to this seat is facilitated by the center console that slides forward for better access.
The Hybrid4 features an internal combustion engine driving the front wheels and an electric motor driving the rear wheels, with no mechanical connection between the two. The SR1 concept uses a 1.6 liter THP (Turbo High Pressure) gasoline engine, a four-cylinder, 16-valve turbocharged engine developed in conjunction with BMW.
The SR1 engine produces 218 horsepower. When combined with the rear mounted 95-horsepower electric motor, a total of 313 horsepower is available for peak performance. Details of the Peugeot 3008 have yet to be revealed. However, shown in Prologue HYmotion4 form, it used a 163 hp, 2.0 liter four-cylinder turbodiesel and a 36 hp electric motor.
Besides four-wheel-drive, the Hybrid4 allows an electric-only mode at lower speeds to make it a zero emission vehicle. When both engine and motor are used it features a combined fuel consumption of only 48 mpg. The SR1 also has four-wheel steering with steering angle controlled as a function of road speed.
