FLEXTREME.

The Opel Flextreme is more than a demonstration of the Opel commitment to the latest green technology, it is proof that the future can be stylish as well as practical.

The Flextreme body’s key characteristics highlight the new elements of Opel design language: more sculpted surfacing molding, clear style elements such as narrow, boomerang-shaped lights and sloping swage line in the side graphics. The Flextreme was also designed following the theme of technological efficiency: vehicle weight and aerodynamics are optimised by using advanced materials and simulation technology.

The bottom edge of the windscreen has been pulled forward, so the bonnet with its characteristic crease is very short. The integrated power socket allows the car to be charged at any mains supply.

A look at the front of the car quickly reveals that the front grill and rims are covered by lightweight transparent trim, which is made from polycarbonate to improve aerodynamics while maintaining visual aesthetics. The same is true for the special light alloy wheels. Like the wheel design, the large boomerang-like curved front light units are visually deceptive.

From the rear the centre opening, butterfly doors form the most immediate feature. Also the relief of the blade motif is carried around the whole curvature of the back. The unique rear lamp clusters with wing lights are virtually invisible until lit, they also wrap around to give even more sense of symmetry. The central focus falls firmly upon the Opel blitz.

Just like all the other windows and a large part of the roof, the windscreen is made of especially light polycarbonate. The Flextreme’s panoramic windscreen provides a light and spacious interior ambience and stretches over most of the roof, which is reinforced by a spine-like composite structure that extends all the way to the rear floor.

New approaches to space, comfort and light, characterise the interior design of the Opel Flextreme.

Set directly under the windscreen, the large panoramic display in the interior is especially eye-catching. The display fields are configurable. They can show a complete all-around view of the car’s surroundings, for example, instead of exterior mirrors the Flextreme has two side cameras, one front-facing and one rear-view camera. A second display on the centre console features touch-screen operation for air conditioning, infotainment and navigation functions as well as the drive selector gate.

A clever storage system at the front and back of the center tunnel offer Opel-typical flexibility. Front and rear passengers can stow items such as mobile phones, MP3 players, iPods and PDAs in two drawers. The electrical devices are wirelessly recharged in the drawers and Bluetooth-capable systems can transmit their data to the onboard infotainment system.

Honeycomb structures, which are characterised 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, load floor and above the central tunnel where the lithium-ion batteries are located.

With the rear-hinged back doors (FlexDoor®) that enable comfortable access to the interior, a large transparent roof and two tailgate doors that open from the side and swing upwards (FlexLoad®), the concept car embodies Opel’s tradition of particularly flexible and practical body concepts with attractive designs.

This also includes the FlexLoad’s additional underfloor luggage compartment the latest in a series of innovative Opel solutions such as the Zafira’s seating system (Flex7®) and the integrated rear carrier system Flex-Fix® found in the Corsa and Meriva.

And the big surprise is the integration of two high-tech electric personal transporters (PT’s), ingeniously packaged below the cargo floor. They can be used in areas where cars are restricted, thereby adding an extra mobility option. The electric scooters provide up to a 38 km (23 miles) of clean mobility.

The Opel Flextreme uses the revolutionary E-Flex propulsion system, which is also referred to as Voltec technology.

E-Flex is a new family of electrically driven propulsion systems specifically engineered for future small- and mid-sized vehicles. The “E” stands for electric drive; the “Flex” represents the architecture’s adaptability. The system allows the flexible use of electricity from a wide range of sources: the generator can run on power from the grid, from a small internal combustion engine consuming unleaded petrol, diesel or bioethanol (E85 – a mixture of 85% ethanol and 15% petrol), or from a fuel cell.

This means that the vehicle’s drive system can be adapted exactly to the needs and infrastructure of specific markets.

In contrast to conventional vehicles and hybrids, the E-Flex system uses an electric motor, powered by a lithium-ion battery, to propel the Opel Flextreme concept for up to 55 km of electric-drive-only range. In this case, a 1.3 CDTI onboard engine generates additional electricity to replenish the battery and extend the vehicle’s driving range. Fully charged, the Flextreme’s 55-km all-electric driving range is enough for most daily commuters in Europe to travel without using any diesel fuel or emitting any CO2.

The Flextreme concept is a good indication of what low-emission mobility could look like in the mid-term.
