Standard equipment includes air conditioning, cruise control, CD-radio with six loudspeakers, power windows, on-board computer, heated power exterior mirrors, radio remote control central locking, height and reach-adjustable leather steering wheel, height-adjustable "Easy Entry" seats with memory function, rear seats with armrest and load-through hatch, and fog lamps.

The Cosmo version also comes with remote control for the roof and a sports steering wheel. Options include the keyless central-locking system "Open & Start", stationary heating, automatic air conditioning, park pilot, mobile phone console with Bluetooth interface, a selection of infotainment and navigation systems, adaptive IDSPlus chassis (Interactive Driving System) with electronic Continuous Damping Control (CDC) and steering-linked AFL bi-xenon headlamps (Adaptive Forward Lighting).

The standard stereo CD-radio has six loudspeakers, RDS and speed-dependent volume control. It is also available with MP3 function. Hi-fi fans will appreciate the CDC 40 Opera sound system with 6 x CD changer; thanks to its powerful 150 watts and seven premium loudspeakers, it has superior sound. The CD 70 Navi complements this with a navigation system including dynamic route guidance. The top DVD 90 Navi includes a DVD-ROM with street maps from 23 European countries and digital travel guide. The 6.5-inch color info display (16.5 cm; optional for CD 70 Navi) allows for precise map display with direct destination selection.



High-tech for driving dynamics and active safety

The IDS chassis (Interactive Driving System) endows the Astra TwinTop with good road-holding, while the optional IDS sport chassis including SportSwitch offers a sportier ride. Unique high-tech options such as the adaptive IDSPlus chassis with electronic Continuous Damping Control (CDC) set the new Astra TwinTop further apart from its competitors. Active driving safety systems such as ABS, ESPPlus and brake assist, all standard equipment, also help to avoid potential accidents.

Top driving performance is ensured by a range of engines featuring four gasoline units (77 kW/105 hp to 147 kW/200 hp) and the 110 kW/150 hp 1.9 CDTI common-rail diesel with Diesel Particulate Filter (DPF) as standard. The top-of-the-line engine is the 147 kW/200 hp 2.0 turbo ECOTEC unit enabling a top speed of 237 km/h. The turbo engines come with front-wheel drive and six-speed manual transmission. The Astra TwinTop's drag coefficient is an excellent 0.31.


Active roll-over protection system

Opel Astra TwinTop body and underbody, based on its Astra GTC sister model, were specially reinforced for the particular demands of a cabriolet. Engineers were therefore able to increase torsional rigidity, important for extremely precise chassis tuning. Compared to the previous Astra Cabrio, an improvement of 30 percent was achieved. To minimize the consequences of a roll-over, the Astra TwinTop features a highly stable windshield frame and active roll-over protection system as standard. A special yaw rate sensor in the airbag control system recognizes sudden vehicle turning motions along the longitudinal or transversal axis. In the event of an impending roll-over, the control system activates the seat-belt tensioners. Simultaneously, two solid aluminum safety roll bars behind the rear seats deploy upwards and lock tight within 0.2 seconds. The system is also activated if the airbag sensors for front or side impacts report a collision. This means the roll bars are in place even if the collision causes a power failure and then a roll-over occurs. The mechanism also works with the roof closed, offering even greater protection. The additional SAFETEC system, which encompasses all active and passive safety elements, also includes two-stage front airbags for driver and front passenger, thorax/pelvis side airbags in front, and three-point safety belts for all passengers. Driver and front passenger also benefit from active head restraints which help to reduce the risk of whiplash in the event of a rear collision.
