Acceleration from rest to 100 km/h takes just 7.5 seconds at sea level - with little drop off at altitude - and the Coupe has a top speed of 245 km/h.
For the 2003 model year the Astra Coupe receives a power increase from 141 kW up to 147 kW at 5 600 r/min for the turbocharged and intercooled Opel ECOTEC Z20LET engine.
Peak torque is a healthy 250 Nm and significantly this level of torque is available from just under 2 000 r/min right through to 5 300 r/min.
Further good news is that Opel engineers have achieved the increase in power together with a slight improvement in fuel economy.
Fuel consumption for the urban cycle is 12.4 l/km while an efficient 6.7 l/100km can be achieved in a top gear cruise. A combined fuel consumption of 8.8l/100km can be achieved.
Also new for the 2003 model year on the Astra Coupe is a refreshed interior with cloth trim. This black cloth trim has a 'waffle weave' design.
As with all models in the Astra 2003 model range the Astra Coupe is covered by the Opel Fixed Cost Motoring Plan.
Valid for five years or 100 000 km this motoring plan covers a wide range of service and maintenance costs to provide excellent value for money motoring and low overall motoring costs.
Options exist to purchase extensions to the Opel Fixed Cost Motoring Plan to provide tyre cover or mileage extensions to 105 000 km, 120 000 km, 135 000 km, or 150 000 km.
Latest generation engine
The Astra Coupe features a latest generation Opel ECOTEC engine with an innovative integral turbo charger system in which the exhaust manifold and turbo housing are combined, together with other associated components, in a single module.
This all adds up to lower weight, compact dimensions, and importantly shorter gas flow paths between the exhaust ports and the turbine.
This integrated turbo module weighs just 7.1 kg, just about 1.3 kg heavier than the cast exhaust manifold of a comparable naturally aspirated engine.
This shortened gas flow paths are important as they add to the efficiency of the turbo thanks to reduced heat losses while the compact nature of the turbo installation adds to the overall space and weight efficiency of the engine.
The four-valve per cylinder twin overhead camshaft engine reacts instantaneously to throttle inputs and delivers its high levels of power and torque with little hint of lag.
Two counter-rotating balance shafts ensure added refinement through a smoother and quieter engine.
A latest generation engine computer system attends to the management of this jewel of an engine.
Among the items it controls are the turbo boost pressure (a maximum of 1.84 bar is allowed) via a wastegate and rotary valve, both integrated into the turbo module; drive by wire accelerator inputs; the mixture as indicated by the hot-film air mass meter; the sequential fuel injection, and the engine ignition timing through individual-coil direct ignition.
A cylinder selective engine knock control is also controlled by the electronic management system.
Features
The Astra Coupe Turbo is fitted with 16X6J alloy wheels fitted with 205/50 tyres. Safety features include Opels patented "Pedal Release System", and front and side airbags for front seat occupants.
Seatbelt pre-tensioners work in concert with the airbags and side impact beams add strength to the doors.
Interior features include an aluminium-look gear knob and sill plates, a handbrake lever with a soft-feel surface and two-colour leather trimmed steering wheel that compliments the overall interior feel.
Sports seats and a full range of adjustments, air conditioning, audio system with CD player, as well as an on-board computer, cruise control and anti-theft alarm and transponder key anti-theft protection are all included in the standard equipment list.
Power assisted steering is of the electro-hydraulic type and side mirrors and windows are power operated.
The Astra Coupe Turbo is fitted with an Electronic Stability Program (ESP), which integrates and coordinates the ABS, electronic braking-pressure distribution (EBD) and traction control systems.
The ESP uses wheel speed sensors as well as other inputs for steering angle, yaw rate, and lateral acceleration, to identify the driver's desired direction of travel and compare that to the cars actual movement.
