Distinguished Wellness Seats for New Opel Astra

– Art of German engineering: All-new comfort seats from Opel
– Unique in compact class: With massage and memory function, plus much more
– Tradition at Opel: AGR (Campaign for Healthier Backs) seal of approval
– Attractive offer: Ergonomic AGR driver’s seat already available from 390 euros

Rüsselsheim. The new Opel Astra celebrates its world premiere at the International Motor Show (IAA) in Frankfurt this fall (September 17 – 27, 2015), but it is already clear today: never before has there been so much luxury in the compact class. The Astra is lighter, more efficient and offers state-of-the-art features; thanks to its advanced seating technology, it makes every drive a relaxing journey. AGR (Campaign for Healthier Backs) certified premium Opel ergonomic seats provide excellent long-distance travel seating comfort. They continue the Opel tradition of award-winning, back-friendly seats. Beyond being 18-way adjustable including side bolster adjustment, they are now optionally available with further comfort features such as massage and memory function along with ventilation – a unique combination in the compact class. Rear seat passengers can also look forward to more luxury – in addition to more legroom, heated outer rear seats are optional. Astra customers can treat themselves to these luxury seats that are completely developed in-house at Opel for very attractive prices – the driver’s seat with the AGR seal of approval is already available from 390 euros.

“Seating is among the most important elements in a vehicle as it delivers safety, comfort, and design. It is one of the reasons we place such a high priority- with the support of our partners- on the development of our seating systems,» says Charlie Klein, Vice President Vehicle Engineering at Opel. «The new Opel Astra seats continue to deliver on the promise of excellence and are a reflection of the skill and commitment of our engineers and designers. The Astra seats provide advanced features in the compact segment that are normally found only in the premium class.»

Lightweight: Seat alone ten kilos lighter

Development of the seating environment in the new Astra already began nearly five years ago for the over 100 employees in the team of experts. “Especially integration of the relatively bulky seats must be considered from the very beginning. This means the seats have to fit into the car accurately to the last millimeter – in every direction,” says Andrew Leuchtmann, Senior Manager GME Interiors. A very challenging task, as the seat components are one of the car’s largest parts. Seat production alone accounts for around ten percent of the total production costs of a new car model.

At the same time, the seats have a large impact on total weight. That is why for their new development, the engineers first had to minutely examine all single elements of the Astra comfort seats that come as standard. “Compared to the predecessor, not one single part is identical,” says the expert. In order to offer rear seat passengers 35 millimeters more legroom, the seat back of the new comfort front seat was made much more compact. State-of-the-art calculation methods enable this, as do lighter polyurethane foams and ultra-high-strength steels that are built in under the seat upholstery. “So the new seats are around ten kilos lighter than those in the previous model,” explains Leuchtmann. This is not only true for the driver and co-driver seats – the new Astra’s rear seats are also lighter and more compact, their contouring was optimized and thigh support was enhanced with a steeper seat tilt.

AGR seal of approval for ergonomic seats

“In-vehicle ergonomics is more than just the seat contouring, it already begins with the positioning of the seat in the car,” says Leuchtmann. The Opel experts also further optimized the Astra comfort seat in this regard, positioning it lower. “This especially accommodates taller drivers with a sporty driving style,” he explains. Thanks to a 65-millimeter height adjustment span – the largest in the segment – shorter drivers are also guaranteed an optimum seating position. With the optional premium ergonomic seat’s memory function, this can even be saved at the press of a button. This is ideal for fleet vehicles with the same group of drivers or couples who share the new Opel Astra. The base version of the optional ergonomic seats comes with four-way electropneumatically adjustable lumbar support (forwards, backwards, up and down), variable seat cushion tilt, cushion length adjustment and a seat form with contours that adapt to the natural curvature of the spine. The premium ergonomic seats also feature electropneumatically adjustable side bolsters that support the body by making the seatback narrower or wider. All these exemplary ergonomic elements made it clear to the AGR (Campaign for Healthier Backs), an independent association of doctors and experts dedicated to preventing back problems, that the new Astra also deserves the AGR seal of approval.

Wellness massage, climate control and heating included

Seats should not only keep drivers securely in place, they should also keep them warm or cool depending on the prevailing conditions. The new Astra comfort seat features passive climate control, meaning breathable surface fabrics and perforated polyurethane foams that considerably improve transporting away moisture and thereby the micro climate in the seat. The new Astra’s premium ergonomic seats can do both – keep warm and cool. Small fans suck air, and thus the moisture that develops when someone is in the seat, away from the body. In the winter, integrated seat heating keeps the driver and co-driver as well as both outer rear seat passengers comfortably warm. Those who want to turn their car into a wellness mobile on longer journeys can enjoy a massage at the push of a button – and arrive at their destination even hours later relaxed and free of aches or pains.

Opel is the leading volume manufacturer of ergonomic seats with the AGR seal of approval. The first ergonomic Opel seat was introduced with the Signum in 2003. Today, in addition to the new Astra, the certified and popular seats can be ordered for many Opel models including the Insignia, Meriva, Zafira Tourer, Mokka and Cascada. “We want to really speed up the democratization of good seats – more Opel models with AGR seats will follow,” promises Andrew Leuchtmann.

Nuevo Astra con tecnología avanzada: motor 1.4 ECOTEC Turbo de inyección directa

[i]– Mecánica de gasolina con cuatro cilindros, completamente de aluminio.
– Respuesta inmediata: reacción dinámica al acelerador y grandes prestaciones.
– Tecnología avanzada: inyección directa de gasolina y turbocompresor para lograr la mayor eficiencia.[/i]

Rüsselsheim/Madrid. Opel mostrará en el Salón del Automóvil de Frankfurt el nuevo motor 1.4 ECOTEC Turbo de inyección directa por primera vez en el nuevo Opel Astra. El motor turbo comprimido de cuatro cilindros con inyección directa central de combustible estará disponible con dos niveles de potencia 125 CV/92 kW y 150 CV/110 kW.

Esta combinación vincula a este nuevo motor de aluminio con el recientemente presentado 1.0 ECOTEC Turbo de inyección directa ya conocido del Opel ADAM y el nuevo Corsa. De hecho, el nuevo cuatro cilindros de 1.4 litros puede considerarse el hermano mayor del de tres cilindros y un litro. Ambos motores pertenecen a la familia de motores pequeños de gasolina; un grupo de mecánicas de tres y cuatro cilindros con cubicajes inferiores a 1.6 litros.

Nueva referencia: motor de cuatro cilindros silencioso como un susurro

Se ha prestado una gran atención durante la fase de desarrollo del motor 1.4 litros Turbo a la respuesta dinámica y altas prestaciones, al tiempo que se ha contenido el consumo de combustible. El motor entrega muy pronto un par máximo de hasta 245 Nm. El máximo está disponible entre las 2.000 y las 4.000 rpm, una zona sorprendentemente amplia. Las condiciones son perfectas para combinar la diversión de conducir con la eficiencia en el consumo.

Según los datos preliminares, el potente motor turbo equipado con tecnología Start/Stop tiene un consumo de sólo 4,9 litros de gasolina cada 100 kms en ciclo combinado (114 gr de CO2 por km). Por tanto, el motor 1.4 litros Turbo podrá competir en prestaciones incluso con motores de dos litros y sustituirlos. Los ingenieros han prestado gran atención al nivel sonoro y el comportamiento frente a las vibraciones durante el desarrollo del nuevo motor, al igual que ya hicieron al desarrollar el motor de un litro y tres cilindros. El bloque motor ha sido construido teniendo en mente la reducción de la resonancia, el cárter de aceite se ha dividido en dos partes, la integración de la culata en el colector de escape está aislada, se ha diseñado una tapa de la distribución que absorbe ruido, se han desacoplado las válvulas de inyección y la cadena de la distribución se ha recortado para que tenga baja concentricidad.

“Nuestro nuevo motor turbo de cuatro cilindros con 1.4 litros e inyección directa central responde a los atributos de potente, eficiente y silencioso. Fabricado completamente de aluminio, además de ser respetuoso con el medio ambiente, establece nuevos niveles en confort de conducción”, dice Christian Müller, vicepresidente de GM Powertrain Europe.

Por su construcción, el nuevo motor 1.4 ECOTEC Turbo de inyección directa añade menos peso al vehículo. Sólo el bloque motor de aluminio pesa 10 kilos menos que el de acero forjado del actual 1.4 litros turbo siendo la elección perfecta para el nuevo y eficiente Opel Astra. Es precisamente en cuanto a eficiencia donde el nuevo 1.4 litros turbo muestra sus avances tecnológicos. Para hacer el motor lo más ligero posible, el cigüeñal es hueco, la bomba de aceite es de baja fricción y trabaja con dos niveles de flujo según sea necesario. Todo el motor está diseñado para funcionar con aceites de baja viscosidad 5W-30. Todas estas medidas aseguran una gran eficiencia en el consumo de combustible.

Mientras que los motores de tres cilindros de Opel son los representantes típicos de los motores de cilindrada reducida (más pequeños, ligeros y eficientes), los ingenieros de Opel hablan de “cilindrada optimizada” cuando, por ejemplo, hablan del perfecto equilibrio entre la eficiencia a alta y baja carga del nuevo 1.4 litros Turbo de cuatro cilindros.
