New greener Vauxhall enginesMay 18, 2012
Vauxhall is replacing the majority of its powertrains over the next year with greener petrol and diesel engines.
The company claims that the new units will lead the industry for CO 2
emissions, economy, torque and refinement.
The first new engine will be a 1.6-litre turbo petrol unit with direct injection and Start/Stop technology that will cut CO 2
emissions by 13 per cent compared with its predecessor. The four-cylinder SIDI (spark ignition direct injection) ECOTEC engine will be available in various outputs and across several car lines.
The company claims that its levels of torque, combined with excellent linearity, reduced noise, strong performance and low fuel consumption will set it apart from its rivals. Maximum torque of 300Nm is achieved from 1700rpm, resulting in a class-leading specific output of 187.5Nm per litre. Peak power is also increased to 200PS at 4700rpm – up 20PS versus the existing 1.6T.
Vauxhall’s first spark ignition direct injection engine, the 155PS 2.2-litre ECOTEC, was first seen in the 2003 Signum and Vectra models, followed by the Zafira. Today, the Insignia 2.0-litre turbo continues the direct injection theme, and is currently available with 220PS and up to 250PS in some European markets.
This summer, the new Astra VXR will adopt a tuned version of the same engine, with a bespoke cylinder head and turbocharger, that produces 280PS, yet produces CO 2
emissions of just 189g/km.
