Opel Flextreme Concept GT/E, exposed to premiere in Geneva, will have an autonomy of 500 km.
Opel will unveil the Flextreme concept electric coupe GT/s in the 80th edition of the Geneva Motor Show (March 4 to 14), it having an autonomy of 500 km. Opel Flextreme GT/E, which has a length of 4.7 meters, illustrating how extended range electric propulsion technology (E-REV) can be used in large or medium sized cars, as well as compact cars such as the future of Amper .
Opel calls it the strategy “e-mobility unlimited“. It is to adapt the E-REV drive system and the limits of the exclusive power of the battery, designed cars of all segments of the automotive market.
Thanks design concept Flextreme Opel GT/s is drag coefficient of 0.22, which help achieve a speed exceeding 200 km / h, and energy conservation and expand the autonomy movement.The vehicle has low ground clearance and a broad structure, front and rear lights in the shape of the wing, front grille and distinctive C pillars designed lecture and body strong, sculptural forms.
“Flextreme Concept GT/E prefigures things to come in future from Opel,” said Frank Weber, Vice President Product Planning and Organizational. “Bold, expressive and extremely effective, it is the product strategy that we use for all our future vehicles, large and small, across all market segments.”
Low proportions, like a coupe, the Flextreme GT/s explores the development potential of the new Opel design language. The front with simple design features include a low bonnet line and an extended section in front, framed by lights with LEDs in the shape of the wing, signature brand. They are carved deep into the front wings and bonnet line. New radiator grille of the trapezoidal shape is narrow, but bold. Prominent chrome bar in the shape of the wing bears a large Opel logo, which also has the role of plug for the battery pack loading Flextreme concept GT/E.
The upper part of the radiator grille is used for cooling air intake, the lower is covered with a translucent panel. The absence of additional inlet slits allow a low front, aerodynamics, and ensuring compliance with future requirements for pedestrian protection.
Sculptural hood with central line bearing the signature of Opel, has narrow longitudinal slits on both sides to ensure venting the engine compartment. Powerful wings and body parts wheels curve, toward the back.
Profile Flextreme concept GT/E is distinguished by innovative C pillars, shortened. This design course allows extending back arched windows below the roof line, emphasizing the flowing lines of the side bodywork. The dynamic nature of the car is underlined even more by this plea blade, Opel‘s characteristic, now a curved line that starts from the C pillar to the bottom of the front wing.
Access to the car is facilitated by the rear hinged rear doors, an evolution of the concept Opel currently FlexDoors monocab new generation Meriva. To keep a harmonious exterior appearance, all the door handles were replaced with light sensors. When are covered with hand driver or a passenger, it opens doors. To reduce resistance, exterior mirrors on the front doors were also replaced with small cameras placed on the pillars A.
Back line includes sculptural passages of wheels, which emphasizes more ground clearance and low and wide structure of the Flextreme concept GT/E. The appearance of a hatchback coupe is supplemented with large tilt angle, which integrates optical blocks shaped rear wing with LED, taking the form of headlights. As if the Insignia Sports Tourer, tailgate has a curved design on the sides, which provide better access to the trunk. Rear window is slightly convex widened to improve aerodynamics.
Transparent glass panel set in the center of the roof can be adapted to allow sun rays to heat inside in winter, but gaining a shade closed to maintain coolness in summer. A channel located in the lower edge of the roof is to further cool the battery and electronic components.
Managing aerodynamics and weight reduction
Because the front of small, low height of the roof (1308 mm) and part of the body flat and covered car cut the air with minimum turbulence.
Aerodynamics was optimized through a series of measures. Alloy wheels are relatively narrow 21 inches to reduce drag, using 195/45 tires with low rolling resistance. Simple insertions mounted level, also help to minimize air currents.
Minimum front air intake improves air circulation in front of the vehicle and the curve of the body above the rear to further reduce drag.
Flextreme Concept GT/s experience also potential active modification of form. At speeds above 50 km/h, a vertical panel extends from the slot venting passages behind the rear wheels.These spoilers side 350 mm long directs high velocity air currents around the back of the vehicle, reducing even more turmoil.
Measures to reduce body weight can remember using lightweight outer panels of composite material with carbon content, with polycarbonate windows and structural components of aluminum alloys. Compared with conventional materials, they provide a weight reduction of 40%, contributing to the decrease of energy consumption and increased vehicle autonomy.
The concept is under the hood E-REV power train of GM, which has been developed for the Opel amps. Although larger and has a top speed exceeding 200 kilometers per hour Flextreme concept GT/s is designed to provide the same performance Amper: a functional autonomy of up to 60 km on the energy provided by battery, with zero CO2 emissions, and total autonomy of over 500 km. Average fuel consumption is estimated at 1.6 l/100 km with CO2 emissions below 40 g / km.
Unlike a hybrid car, the wheels are always electric concept. For trips up to 60 km, energy is provided by a lithium-ion battery pack to form the letter T located beneath the floor and rear seats.
However, unlike an electric car battery acted alone, Flextreme concept GT/E eliminates any concern for the autonomy of movement and fear of running out of energy source. Small generator / gasoline engine produces power without discontinuities, if the resources are low battery. Thus, autonomy is extended over 500 km, until the moment you can recharge by connecting to the electricity network or can be fuel vehicle refueling.
Electric propulsion engine unit generates instantaneous torque of 370 Nm, which ensures a planned acceleration from zero to 100 km/h in less than nine seconds.
Flextreme Concept GT/s is still a step in the strategy Opel ongoing electrification of vehicles, including a broad portfolio of products that use batteries technologies, with extensive autonomy, with drive hybrid and fuel cell.
