Opel’s Flextreme Concept Car
Opel’s Flextreme concept car, boasts the body of a dynamic monocab, as well as the completely new environmentally friendly E-Flex electric propulsion concept and a host of innovative details.

Plug-in – full capacity after three hours of charging at 220 volts
three-cylinder turbo gasoline engine designed for operation with gasoline or E85 (a mixture of 85 percent ethanol and 15 percent gasoline).
Exterior design: Dynamic design language in compact monocab form
The long Flextreme was also designed following the motto of technological efficiency: vehicle weight and aerodynamics are optimized by using advanced materials and simulation technology. The result is a wide range of innovative solutions.
Doors: Unconventional and practical
In keeping with the vehicle’s extraordinary features, access to the FlexLoad® luggage compartment is through two butterfly rear tailgate doors that individually swing open upwards along the central axis of the vehicle. The advantage is that the Flextreme’s trunk is accessible from the side when parked tightly against a wall or another vehicle.
Interior: Futuristic and top technology
Honeycomb
structures, which are characterized by low weight and high rigidity,
are used extensively in the Flextreme’s interior. This functional,
geometric structure can be found in the instrument panel’s lower
portion, cabin floor, cargo floor and above the center tunnel where the
lithium-ion batteries are located
