In Opel strategy to achieve greater independence from fossil fuels, electricity plays an important role. The 4.7 meters long Flextreme Opel GT / E Concept demonstrates how the long-term electric vehicles (E-REV) technology can be plugged into a large or medium-sized vehicles and compact cars such as the future AMPERA Opel .
Opel calls this strategy of e-mobility is limited: to customize the E-REV highly efficient drive system – which eliminates the limitations of battery power only – for vehicles in all market segments. To make driving with zero emissions of CO2 style Flextreme Opel GT / E concept shows that size does not matter.
Design also allows the Flextreme is Opel GT / E concept for achieving the projected drag co-efficient of only 0.22, which helped her to reach 200 km / h speed, higher and save energy and extend the driving range. Stand-out visual features, including the down position and width, the front and rear lights shaped wings, nose and distinctive grille, floating C-pillar and the muscular, chiseled body.
“The Flextreme Opel GT / E concept shows the form that will come from Opel,” said Frank Weber, Vice President, Corporate and Product Planning. “Bold, expressive and very efficient, it is our product strategy apply to all our future vehicles, large and small, across all market segments.”
Exterior Design: the effectiveness of expressing emotions
Low, coupe-like proportions Flextreme Opel GT / E Concept explores the potential development of new language as Opel – art sculpture meets German precision – in an envelope is optimized for aerodynamic efficiency.
Clean, Styling front has a low hood line and forward fuselage widened, which held the wing-shaped LED light signature. This is engraved on the front fenders, hood and crossing lines. New trapezoidal grille running thin but thick. Prominent wing-shaped chrome bar Opel carrying a large sign, which is an outlet to charge Flextreme Opel GT / E Battery Concept.
The top of the screen used to give air, the bottom is covered by a translucent panel. The absence of additional air supply allows low frontal area for aerodynamic efficiency and also allows the Flextreme Opel GT / E concept to meet future pedestrian protection.
A sculpted hood with the signature crease lines Opel central elements narrow longitudinal vents on each side to pull air out of the engine compartment. Muscle wings and the rear wheel-arch swept to the side of the body.
, Profile Flextreme Opel GT / E concept is distinguished by innovative, turn off the C-pillars. This design allows the floating greenhouse will be extended to the rear under the curved roof line, emphasizes the flowing lines of the side of the body. Dynamic character of the car was also stressed by a new pattern of expression signature blade Opel, now based online crimping the bottom of the C-pillar to the bottom of the front bumper.
Access to the cabin is reinforced by the adoption of rear doors hinged at the rear, an evolution of the concept of FlexDoors Opel Meriva minivan next generation. To maintain a clean appearance, every door handle is replaced by the light sensor. This has triggered an open door when closed by the driver or passengers’ hand. To reduce the turbulence of the air outside the front door of the mirror also absent, replaced by a small camera that shoots at the base of the A-pillars.
At the back, strong shoulder line includes wheel arch statue is more emphasized Flextreme Opel GT / E of a broad concept, stuck to the ground position. Coupe see addressed by scraping a large truck carrying the wing-shaped LED light that echo the shape of the headlights. From the Insignia Sports Tourer, the tailgate has a cover design for increased access to the trunk. Deep glass screen slightly convex to increase the airflow.
A panel of translucent glass remained in the middle of the roof is adaptive, allowing sunlight to warm the interior in the cold of winter, but the evil coolness in summer. A canal to the rear of the roof is cooling extra batteries and electronic components.
The management of air flow and reduce weight
An integral part of the Flextreme Opel GT / E Concept expressive eyes is the effective execution of design. Small frontal area, low roof height (1308 mm) and a base plate covered every opportunity possible to split the air with minimal disruption.
A series of measures to optimize the management of airflow. 21-inch alloy wheels are relatively close to reduce wind resistance, and fitted with 195/45, lower rolling resistance tires. Obviously, flush-mount trim inserts also minimize air turbulence.
Minimal increase the intake flow of air around the nose of the car and sweep the underbody in place, like Venturi, at the rear to reduce drag.
Flextreme Opel GT / E concept also explores the potential change in the active form. At speeds above 50 mph, the vertical bar extends along the body of extracting air from each slot in the back of the rear wheel-arch. The 350 mm long side guide spoiler high airflow speed around the rear corners of the car, thereby reducing the amount of turbulence.
Weight reduction for the body, including the use of lightweight carbon composite exterior panels, polycarbonate windows and aluminum alloy structural components. Compared to conventional materials, it offers a savings of 40 percent by weight which also contribute to reducing energy consumption and increase driving range.
Innovative propulsion
GM efficient concept also includes an innovative program E-REV drive system has been developed for Opel Ampera. Flextreme Opel GT / E Concept demonstrates the flexibility of this technology to display a large, medium size vehicle.
Apart from the greater size and a maximum speed of over 200 miles per hour, Flextreme Opel GT / E concept is projected to offer performance similar to Ampera: pile driving range 60 km – with zero tailpipe emissions CO2 – and the total range of over 500 km. The average fuel consumption is estimated at 1.6 l/100 km with CO2 emissions below 40 g / km.
Unlike hybrid vehicles, the Opel Flextreme Wheel GT / E concept supported each time by electricity. For the typical travel up to 60 km, the energy provided by the T-shaped lithium-ion batteries located under the floor and the rear seat.
However, unlike a battery electric vehicle only Flextreme Opel GT / E concept eliminates the possibility of the reach of anxiety for fear of drifting without power. Small gasoline engine / generator was engaged to provide cheap energy supply whenever the battery is discharged. In this mode, the driving range is extended to more than 500 km, until the plug-in rechargeable battery or a car to refuel.
In a motor control unit provides a significant power 370 Nm of instant torque, agile performance and projections of zero to 100 km / h in under nine seconds.
The Flextreme GT / E concept is the next stage which lasted Opel’s strategy for the electrification of the car, which includes a variety of portfolio products that use batteries, extending coverage, hybrid technology and fuel cell.
