Five-door is first variant of fifth generation model range, adaptive, electronic IDSPlus suspension system, Continuous Damping Control (CDC), common rail turbo-diesels up to 150 hp and petrol engine power up to 200 hp

Vauxhall today released the first details of its fifth generation Astra range – dynamic looking, fun to drive and with a host of features new to the compact cars class.

The new model goes on sale next spring and will first be seen at the Frankfurt International Motor Show in September.

The technological highlights of the fifth generation Astra include the adaptive suspension system IDSPlus (Interactive Driving System) with Continuous Damping Control (CDC).

Lighting first

Vauxhall’s new AFL (Adaptive Forward Lighting) headlamp system, is offered for the first time in the Astra-size segment.

More state of the art engineering is illustrated with automatic headlamp activation, which switches the car’s lights on automatically in the dark, and new TWINPORT petrol and common rail turbo-diesel engines.

The new Astra offers more passenger space than its predecessor, thanks to its slightly increased overall dimensions (around 5.5 in/14 cm longer, 1 inch/2 cm wider and 4 cm/1.6 in higher).

Initially five petrol and three turbo-diesel engines – 1.4 to 2.0 litre with power outputs in the 80-200 hp range – will be available.

All are ECOTEC four-valve units that meet the Euro 4 exhaust emission standard. New are the 1.9-litre CDTI diesel (150 hp) and the 170 hp 2.0-litre turbo petrol engines (alongside the 200 hp version due to go into Astra in 2005), coupled as standard to a new six-speed manual transmission. Vauxhall is also offering a five-speed manual gearbox, an automatic and Easytronic automated manual transmission.

Externally a high shoulder-line, strong wedge shape, pronounced wheel arches and clear-cut window graphics are all a part of Vauxhall’s new design cues. The bold face features a wide grille and three-dimensional, clear-glass headlamps.

Sleek appearance

The large rear lamps have a special light-scattering, "translucent" technology. The low curved roof-line, combined with the tapering front and rear overhangs, the long wheelbase (103 in/2.61 metres) and the wide track, all work together to give the new Astra a sleek appearance. It will for the first time in Astra, feature 18-inch light-alloy wheels available direct from the factory as an option.

The suspension features MacPherson struts and a subframe at the front, and a torsion beam with double-walled, U-shaped profile at the rear. The design not only retains all the advantages of a conventional torsion beam axle – such as minimal space requirements, low weight and high camber control – but can also be precisely tuned to the specific requirements of different variants within the model range.

A major option is the adaptive IDSPlus suspension system with Continuous Damping Control (CDC). The basis is a new electronic architecture with three CANBUS systems (Controller Area Network).

Thanks to CDC, the dampers react in real time to variations in the road surface or driving style and adjust themselves automatically to the prevailing conditions. With the IDSPlus system, the Astra’s driver can switch to a sport mode that regulates the damping characteristics as well as the response of the accelerator pedal and the power assistance of the electro-hydraulic steering.

With the automatic and Easytronic transmissions the gears are also selected at higher engine speeds.

The five-door model will be followed later by the estate and sporty three-door.

Prices will be announced closer to on-sale date.
