High torque and low fuel consumption
- Only 4.8 liters of fuel per 100 kilometers
- Very compact, high-tech, common-rail diesel with variable turbocharger
- High refinement, new six-speed manual transmission standard equipment
The state-of-the-art engine made its dÃƒÆ’Ã†â€™Ãƒâ€šÃ‚Â©but 18 months ago in the diesel-record-setting ECO Speedster. Now a new 66 kW/90 hp version of the 1.3 CDTI common-rail turbo-diesel with 200 Nm torque powers the Astra while consuming only 4.8 liters of fuel per 100 km. The new engine comes as standard with a newly developed, six-speed manual transmission and impresses with its smooth performance and high refinement. The Astra 1.3 CDTI makes its world premiere at the RAI Amsterdam Motor Show from February 10-20, 2005. Customers in Germany can order the new engine in the five-door Astra beginning in spring.
Developed by Fiat-GM Powertrain, the 1248 cm3 four-valve power unit with a compression ratio of 18:1 features cutting-edge diesel technology. Its high-pressure common-rail injection system (1600 bar) provides up to five injections per cycle, for ultra-fine fuel atomization - a key factor for smooth running and performance. A highly stable grey cast iron casing (bore x stroke: 69.6 x 82 mm) further contributes to the engine's exceptionally smooth running characteristics. The bed-plate and cylinder head are machined in lightweight aluminum. Contrary to the 51 kW/70 hp 1.3 CDTI unit with 170 Nm, which is offered in the Corsa, Tigra, Combo and Agila models, the new engineÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€šÃ‚Â´s turbocharger features variable geometry, enabling maximum torque of 200 Nm at 1750 to 2500 rpm. Peak power of 66 kW/90 hp is delivered at 4000 rpm. The very compact 1.3 CDTI (length/width/height: 460/500/650 mm) is the smallest common-rail turbo-diesel engine in the world.
With specific power and torque values of 72.1 hp and 160.26 Nm per liter displacement respectively, the 90 hp 1.3 CDTI is one of the top four-cylinder diesel engines in the industry. It takes the five-door Astra 1.3 CDTI to a top speed of 172 km/h, and accelerates from zero to 100 km/h in 13.7 seconds. Thanks to an oxidation catalyst near the engine and cooled exhaust gas recirculation, the Astra 1.3 CDTI complies with the Euro 4 emissions standard.
The Astra 1.3 CDTI is an extremely economical car, not only due to its low displacement and fuel consumption (urban/extra-urban/combined: 6.2/4.0/4.8 liters per 100 km), but also thanks to its exceptionally long service intervals (up to two years/up to 50,000 km) and maintenance-free, chain-driven valve gear.
