Opel Flextreme GT/E shows not only a study that conveys the concept of Ampera as an electric vehicle with a longer range in the middle, but also a technology carrier for aerodynamic optimization. The Flextreme despite a series of measures the wind and has a drag coefficient of just 0.22. The underbody of the 1.31 meter high and 4.70 meters long vessel is smooth, cameras in the A-pillar, the rear view mirror and replace also reduces air vortex. The narrow 21-inch alloy wheels reduce drag, and special 195/45er tires reduce rolling resistance. At speeds above 50 kph further from the ventilation slots of the rear wheel arches parallel to the body from vertical spoiler. The 350 mm long baffles direct the air flow-around the tail and thus also reduce turbulence, improving the air flow. The roof was also designed to be especially streamlined and has a glass pane. As they pass through in winter the sun’s rays and thus warming the interior, the glass darkens in the summer and makes for a pleasant climate. The wheels are covered with transparent lids.
The Opel Flextreme GT/E Concept drives like the Ampera, comes the end of 2011 to the market, is also up to 60 kilometers purely electrically, before a small engine helps to recharge the lithium ion battery during operation, thus a total of more than 500 kilometers with Electric drive possible. The average fuel consumption is around 1.6 liters per 100 kilometers. This corresponds to CO2 emissions of less than 40 grams per kilometer. The Flextreme is more than 200 km/h fast, from the start, the available torque is 370 Newton meters and provides for an acceleration from zero to 100 km/h in under 9 seconds.
