The future is fascinating

The overall style and design of the Flextreme GT/E Concept is a further evolution of the Vauxhall design-language first seen in the Insignia and the all-new Astra. The Flextreme GT/E Concept carries many clues to future design elements in Vauxhall cars.

Low, road hugging and confident, the Flextreme GT/E Concept is a full 5-door coupé with four, full-size seats.

  • Expressive wing-type headlamps to emphasise the sculptured lines.

Profile design

From the side the iconic sculpted profile conveys the welcoming yet sporting nature of the Flextreme GT/E Concept.


Key features include:

  • Low coupé-like profile, creating optimum, wind-cheating teardrop shape
  • Rear view cameras instead of outer mirrors
  • Rear-hinged FlexDoors®
  • Fingerprint-recognition sensors to replace door handles
  • “Floating” C pillars for longer glazed area
  • Full-length glass roof
  • New interpretation of the “blade” side-sculpting first seen on the Insignia.

Rear design

Even a brief glance reveals that the rear treatment is designed with characteristic dynamism.


Key features include:

  • Prominent protective bumpers
  • Broad 'shoulders'
  • Rear lights that echo the unique 'wing' motif of the front daylight-running lights.

Adaptive translucent roof

A full-length glass sunroof makes the interior of the Flextreme GT/E Concept light and airy. It is light-sensitive so that, as the sunlight and heat increase, it darkens protectively.


The sunroof delivers:

  • Controlled natural light and heat
  • Power-saving for the air conditioning
  • A refreshing, naturally lit inner ambience.

FlexDoors® system


Access to the rear seats is made easier by the evolved, unique portal doors first seen on the Meriva. Benefits of the FlexDoors® system include:

  • Front and rear doors open independently of each other
  • Easier rear cabin entry in tight parking spaces.
