Holden Astra Sri 2.2
Powertrain
Holden engineers carried out extensive validation testing to ensure that the new generation 2.2 litre 16 valve ECOTEC DOHC engine specified for the Astra SRi satisfies a wide range of Australian requirements.
The engine develops 108kW of power at 5,800rpm and 203Nm of torque at 4,000rpm using premium unleaded fuel. It achieves fuel consumption figures of 9.0 litres/i 00km on the city cycle and 5.8 litres/i 00km on the highway cycle with manual transmission and 9.0 litres/i 00km on the city cycle and 5.6 litres/i 00km on the highway cycle with automatic transmission. The Astra SRi is also tuned to run on standard unleaded fuel.
The Astra SRi 2.2 litre engine is mated to heavy duty versions of Astra's five-speed, close ratio manual transmission and optional four speed electronic automatic.
Fuel consumption of the car is good - we recorded a figure of 8.4 litres/100 while the AS2877 government test figures are 9 litres/100km (city) and 5.8 litres/100km (highway). NVH is generally up to class levels, with engine noise particularly well suppressed. However on some road surfaces we noticed a lot of deep, boomy noise from the tyres and suspension.
