Opel Astra Sedan
The Opel Astra Sedan boasts the Astra's progressive, proportionally balanced design and dynamic lines. With the latest upgrade of the Astra family of cars earlier this year, designers further honed the distinctive brand face that was first presented in this model line, while ensuring the car is still clearly recognizable as a member of the Astra family. Elements such as the sharply drawn "eyebrows" above the fog lamps serve as a blueprint for future Opel models, while the dynamic V-shaped front is also eye-catching. The headlamp housings in stylish chrome look also convey an additional sense of quality.
Well-balanced proportions are the basis for the harmonious body lines of the Opel Astra Sedan. It is based on the station wagon's long wheelbase, providing a generous 2703 millimeters (90 mm more than hatchback) between the axles and helping to create ample leg room for rear passengers. The new roof line flows elegantly into the tailgate, which turns slightly upward at the end to form an integrated spoiler for optimized aerodynamics. The Opel Astra Sedan achieves a drag coefficient of cD = 0.3, resulting in a drag area (cD x A) of 0.68 m².
At 4.59 meters long, 1.75 meters wide and 1.46 meters high, the Opel Astra Sedan is a fully grown family sedan with a trunk to match. It offers a luggage compartment volume of 490 liters (VDA standard), which expands to a maximum of 870 liters (measured to the upper edge of the fronts seats with the rear seat backs folded down). Maximum load width is 907 millimeters, with the luggage compartment offering a maximum width of 1170 mm and a maximum length of 995 mm, which can be expanded to 1721 mm.
The new-edition Astra's interior boasts surfaces with an even more high-quality look and feel. Distinctive design elements in the cockpit include the prominent center console, additional chrome rings for the air conditioning and radio controls, as well as new trim for the doors and instrument panel, which also boasts three-dimensional instruments. The top Cosmo variant features décor trim and inlays made from luxurious piano lacquer surfaces on the center console and steering wheel as standard.
Wide range: Four engines and four transmissions available
Four state-of-the-art ECOTEC gasoline and diesel engines are available for the four-door Astra: two gasoline engines (1.6 ECOTEC/115 hp, 1.8 ECOTEC/140 hp) and two diesel engines (1.3 CDTI/90 hp, 1.7 CDTI/100 hp). The transmission range includes five-speed and six-speed manual gearboxes, four-speed automatic, as well as an enhanced automated Easytronic manual transmission.
The entry-level 1.6 ECOTEC gasoline engine's maximum output is 85 kW/115 hp at 6000 rpm. Combined with the five-speed manual transmission, the Opel Astra Sedan accelerates from zero to 100 km/h in 11.7 seconds and reaches a top speed of 191 km/h. The modern weight-optimized unit features cam-phase technology, which varies the two camshafts to correspond to the driving situation via a vane-type hydraulic adjuster. This dynamically adjusts the continuous variable valve timings for the intake and outlet sides in every operating state, further reducing both consumption and emissions. Maximum torque of 155 Nm is delivered at 4000 rpm. Combined fuel consumption with the manual gearbox is 6.6 liters per 100 kilometers. The optional five-speed automated Easytronic transmission, which comes with Hill Start Assist (HSA), further reduces fuel consumption to 6.4 liters. The ESPPlus-based HSA system makes starting the car on an uphill gradient easier by preventing the car from rolling backwards without the use of the handbrake. After releasing the brake pedal, pressure in the system is maintained for 1.5 seconds, giving the driver enough time to select a gear and press the accelerator. It also prevents the car from rolling forwards when attempting to drive backwards up a hill.
The top-of-the-line 1.8-liter, 103 kW/140 hp gasoline engine promises plenty of driving fun. In order to optimize consumption and performance, this high-tech engine also operates with two variable camshafts, just like its smaller brother.
With a power output per liter of 57 kW, the 1.8 ECOTEC engine is one of the most powerful in this displacement class. Ninety percent of the 175 Nm maximum torque is available over a wide range from 2200 to 6200 rpm, which ensures lively performance even at low engine speeds for relaxed driving.
In combination with the five-speed manual gearbox, the Astra 1.8 accelerates from zero to 100 km/h in 10.2 seconds and reaches a top speed of 207 km/h. Combined fuel consumption is 7.4 liters per 100 kilometers. With the optional four-speed automatic transmission, maximum speed is 188 km/h and acceleration from zero to 100 km/h takes 11.4 seconds. Combined fuel consumption is 7.8 liters per 100 kilometers.
Low fuel consumption is a trademark of modern Opel diesels. At market launch, the new Opel Astra Sedan was available with the very compact 1.3 CDTI ECOTEC with 66 kW/90 hp and maximum torque of 200 Nm at between 1750 and 2500 rpm. The multi-injection unit features variable geometry turbocharging and intercooling. The Opel Astra Sedan with the 90 hp, 1.3 CDTI engine needs only 5.1 liters of fuel per 100 kilometers (combined). With its standard six-speed gearbox, the Astra 1.3 CDTI reaches 172 km/h and accelerates from zero to 100 km/h in 13.7 seconds.
Fuel supply to the multi-injection system with five nozzles is controlled by a solenoid valve. The injection system is characterized by minimal response time (max. pressure 1600 bar), resulting in extremely fine fuel atomization and up to five injections per cycle. This not only ensures exceptionally economical consumption and favorable emissions values, but also refined and low-noise operation. For example, a pre-injection during the warm-up period reduces cold-start knock to a barely perceptible level. This engine, the world's most compact four-cylinder common-rail diesel unit with turbocharger and named "Engine of the Year 2005" by the media (length/width/height: 460/500/650 mm), is equipped with a lightweight aluminum cylinder head and a weight-optimized grey cast iron engine block. The four-valve engine's two overhead camshafts are powered by a cog-belt drive and activate the valves via roller cam followers.
Shortly following its market launch, the Opel Astra Sedan became available in a more powerful version with a new 1.7-liter common-rail diesel power unit with 74 kW/100 hp. The 1.7 CDTI has a variable-turbocharger and develops a maximum torque of 240 Nm. The 1.7 CDTI engine comes with a six-speed gearbox.
The Astra offers top agility and precise handling with high levels of driving safety. The Opel Astra Sedan's IDS suspension (Interactive Driving System) is designed and tuned for exceptional agility and a high level of active safety.
Major contributions are made by the ESPPlus (Electronic Stability Program) and enhanced McPherson front suspension with hydroformed subframe. The latter provides increased driving comfort thanks to decoupled support bearings and weight-dependent spring rates. The rear wheels are on a specifically adapted torsion-beam axle with double-walled U-pattern section. This construction combines the advantages of conventional wishbone axles like reduced space requirements, lower weight and high chamber thrust rate, with the ability to make exact adjustments to the very specific requirements of various models within the model range. In manufacturing the torsion beam axle, the patented Magnetarc welding technique is used.
This makes various wall thicknesses possible for the torsion profile (stabilizing effect against sideways tendencies) and various angling tendencies in the profile cross-section (control and self-steering effects).
Standard safety features of the Opel Astra Sedan include front and rear disc brakes (ventilated in front), ABS, Cornering Brake Control (CBC), brake assist, as well as the fuel-saving Electro-Hydraulic Power Steering (EHPS). This energy-saving hydraulic pump, which is activated by an electric motor, is only used when needed, thereby reducing fuel consumption.
Cornering Brake Control (CBC) optimizes braking distance and driving stability, also when braking in curves. When wheel sensors register different wheel rpm right and left in a curve, braking force at the inner wheels is reduced while brake pressure is applied under the ABS limit. This creates torque that stabilizes the vehicle. Brake assist is a sub-function of the brake booster. It progressively generates the maximum braking pressure if the brake pedal is pressed particularly quickly, thus reducing the braking distance.
Standard wheel size is 6.5 x 15 with tires 195/65 R 15-91 H. 6.5 x 16 wheels with 205/55 R 16-91 H tires are available as an option for all models. Gasoline versions can also be fitted with 215/45 R 17-91 V tires on 7J x 17 wheels.Hide -
