Vauxhall set for a trio of new engine ranges


In the next 12 months, we’ll be replacing the core of our petrol and diesel line-up with three all-new engine ranges that promise to lead the industry for C0₂ emissions, economy, torque and refinement.

The first of these is a new 1.6-litre turbo petrol engine with direct injection and start/stop technology that cuts C0₂ emissions by 13 per cent, compared with its predecessor. The four-cylinder spark ignition direct injection (SIDI) ECOTEC engine will be available in various outputs and across several car lines.


What sets this new engine apart from rivals is its levels of torque, combined with excellent linearity, reduced noise, strong performance and low fuel consumption. Engineers achieved maximum torque of 300Nm from 1700rpm, resulting in a class-leading specific output of 187.5Nm per litre. Peak power also increased to 200PS at 4700rpm – up 20PS from the existing 1.6T.


“The quality, reliability and driveability of our cars is improving at an unprecedented rate,” says Duncan Aldred, Chairman and Managing Director of Vauxhall Motors. “Replacing core engine ranges with high-output, high efficiency units will enhance our cars’ appeal still further and reinforce our commitment to producing first-class products.”


Our first SIDI engine, the 155PS 2.2-litre ECOTEC, appeared in the 2003 Signum and Vectra models, and then in the Zafira. Today, the Insignia 2.0-litre turbo continues the direct injection theme. It’s 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, which produces 280PS with emissions of just 189g/km.


Production of the SIDI ECOTEC 1.6-litre turbo engine will begin at the Szentgotthardt plant in Hungary in late 2012.
