Opel Antara GTC Concept (2005)

Opel Antara GTC Concept

+ Sporty concept of an off-road coupe
+ New SUV interpretation of dynamic Opel design

Rüsselsheim/Frankfurt. With its four-wheel drive Antara GTC concept vehicle (Gran Turismo Crossover), Opel demonstrates just how dynamic and athletic an SUV (Sport Utility Vehicle) can actually be. The study has its premiere at the International Motor Show in Frankfurt (IAA) from September 15-25, 2005. With the characteristic three-door design (length/width/height: 4530/1970/1640 mm), Opel shows a particularly sporty interpretation of an SUV and its dynamic design language in this special vehicle format. With the striking LED headlamps that run well into the fenders, and the brand's typical crease in the engine hood, the front of the four-seater accentuates Opel's new design line. Viewed from the side, attention is captured by the frameless windows that drop right down and contribute to the coupe-like silhouette.

"The Antara GTC concept vehicle conveys 'adventure' - even when standing still. It leverages Opel's current design language and reinterprets it for the SUV genre," explains Bryan Nesbitt, Executive Director, GM Design Europe. "Contrary to traditional off-road concepts, the Antara GTC communicates that its true home is more on the road than on rough terrain."

For Alain Visser, Executive Director for European Marketing at Adam Opel AG, the Antara GTC is a convincing ambassador of the brand: "Anyone who has been lucky enough to see the Antara GTC has felt instinctively: 'Here comes a strong Opel.' As a surprisingly sporty SUV concept, the study also symbolizes Opel's innovative strength."

With a number of optical and technical details and typical Opel versatility in the interior, the study also sets out to satisfy demanding practical requirements. The tailgate, for example, has a pantographic hinge. Thanks to this innovative design, when it is opened, it swings upwards and to the front so that the person loading the vehicle is not forced to take a step backwards. This provides more convenient access to the load compartment. The two rear seats can be folded away completely from the rear of the vehicle, producing a completely flat loading area. The front seats are anchored on mono-rails and look as if they are floating. With the aid of an EasyEntry system, they slide forward at the press of a button up to the instrument panel to allow the passengers to climb more easily into the rear seats.

Beneath the hood, the Antara GTC features a 212 hp twin-turbo version of the 1.9 CDTI four-cylinder engine. The transverse installed concept power plant produces 400 Nm starting at 1400 rpm, and, like all 1.9 CDTI engines in Opel models, is equipped with a maintenance-free particulate filter (DPF). In combination with the six-speed automatic transmission, the performance is outstanding: computer simulations show a top speed of over 210 km/h and an acceleration from zero to 100 km/h in around 8 seconds.

With the Antara GTC, Opel is continuing its series of exciting studies, each of which accentuates the new dynamic design language in various vehicle classes and reinterprets it for the particular segment. They include concepts such as the GTC Genève (Geneva 2003), Insignia (IAA 2003), Trixx (Geneva 2004) and VX Lightning (London 2003).

Strong Common-Rail Diesel with Twin-Turbo Technology

The Opel SUV study is powered by a 156 kW/212 hp twin-turbo version of the successful 1.9 CDTI ECOTEC common-rail diesel engine. With its hefty torque at low engine speeds (max. 400 Nm from 1400 rpm.), the two-stage turbocharged concept diesel unit is absolutely ideal for this type of vehicle. In combination with the six-speed automatic transmission, computer simulations yield statistics that are impressive for the four-wheel driven Antara GTC concept: A top speed of over 210 km/h and an acceleration from zero to 100 km/h in around 8 seconds.

The transversally installed four-cylinder engine features two overhead camshafts, four valves per cylinder and a variable turbo blade geometry. The fuel supply to the cylinders is controlled by a common-rail system with a pressure of up to 1600 bar.

The heart of the innovative twin-turbo technology of the concept diesel engine is forced aspiration through two exhaust-driven turbochargers, which unlike "biturbo" systems operate in series rather than in parallel: A smaller, highly responsive turbocharger for the low engine speed range, a larger turbocharger designed for high output to take over as the revs build up. Thanks to its superior efficiency, the twin-turbo system can achieve an extremely high specific power output, without disadvantages in fuel consumption and exhaust emissions. Like all Opel's 1.9 CDTI production cars, the Antara GTC concept is equipped with the maintenance-free diesel particulate filter system (DPF).

The modern chassis of the Antara GTC is also dedicated to agile handling. McPherson struts are used on the front axle, and there is a four-link axle at the rear. The rack-and-pinion power steering guarantees precise handling.
