Within the next 12 months, Vauxhall/Opel’s core will be replacing its petrol and diesel lineup with three all-new engine families that are expected to lead the industry when it comes to CO2 emissions, economy, torque and refinement. At the top of this range is a new 1.6-litre turbo petrol engine that features direct injection and Start/Stop technology. Its CO2 emissions level is lower by 13% compared with its predecessor. The four-cylinder SIDI (spark ignition direct injection) ECOTEC engine will be offered in different outputs and through a number of car lines. What make it stand out from rivals are its torque levels, combined with outstanding linearity, reduced noise, strong performance and low fuel consumption. Its engineers were able to attain a maximum torque of 300Nm from 1700rpm, leading to the top-of-the-class specific output of 187.5Nm per litre.
In addition, its peak power increased to 200PS at 4700rpm, higher by 20PS compared to the current 1.6T. Duncan Aldred, Chairman and Managing Director of Vauxhall Motors, said that the quality, reliability and driveability of its cars are improving at an unmatched rate. Aldred said that the appeal of its cars will increase some more and strengthen its commitment to making first-class products as it replaces its core engine ranges with high-output and high efficiency units.
The 155PS 2.2-litre ECOTEC, the first spark ignition direct injection engine of Vauxhall, appeared first in the 2003 Signum and Vectra models, with the Zafira following on its tails. But now, the Insignia 2.0-litre turbo continues the direct injection theme. It is presently offered with 220PS and as high as 250PS in several European markets. For the upcoming summer, the new Astra VXR will use a tuned variant of the same engine, with a bespoke cylinder head and turbocharger that generates 280PS but has CO2 emissions of only 189g/km. The Szentgotthardt plant in Hungary will start production in late 2012.
