New Generation 1.6 Turbo begins powertrain renewal at Opel
Opel is fundamentally renewing its engine range. Three completely new gasoline and diesel families are replacing the core of the current portfolio. The aim is to take an industry lead, not just with fuel consumption and emissions but with specific torque and noise reduction.
The first new engine to be introduced is a turbocharged 1598 cc, four cylinder gasoline unit with direct injection and Start/Stop. The new SIDI (Spark Ignition Direct Injection) ECOTEC engine will be available in various power outputs and across several car lines. Production at the Szentgotthardt plant in Hungary will begin in late 2012.
Smooth acceleration, strong pulling power, low noise levels and low fuel consumption were the main focus. The emphasis was on torque with the engineers achieving up to 187.5 Nm per liter of displacement – a benchmark for gasoline engines produced in high volume. Maximum torque is up to 300 Nm and is already available at 1,700 rpm. Peak power of up to 200 hp is reached at 4,700 rpm. Compared to the predecessor 1.6 liter turbocharged gasoline engine, fuel consumption and CO2 have been cut by 13 percent.
The first Opel engine with Spark Ignition Direct Injection technology, the 114kW/155 hp “2.2 ECOTEC Direct” made its debut in Opel’s Signum and Vectra in 2003, succeeded by the Zafira. In 2007, the GT offered the first turbocharged gasoline engine with Direct Injection from Opel, a 2.0 liter unit with 194kW/264 hp. One year later this engine was introduced in the Insignia and was available in the Opel flagship in two variants: 162 kW/220 hp and 184kW/250 hp. The new Astra J OPC will be powered by the latest version of this engine offering an output of 206kW/280 hp.
