Vauxhall unveils Euro6-compliant new large 2.0-litre eco engine
Vauxhall has unveiled its new, more powerful Euro6-compliant 168bhp 2.0-litre CDTi diesel engine ahead of the Paris Motor Show which will open later this week. The engine will find its way under the bonnet of the Zafira Tourer and the Insignia – helping the latter to fend off the likely increase in threats that stronger revised versions of the Volkswagen Passat and Ford Mondeo will present. The new engine will replace the existing and ageing 2.0-litre CDTi unit.
Compared to the engine it replaces, the new engine will deliver a 5% improvement in the power that is on offer, an enhanced 14% more torque (295lb ft at from 1750rpm to 2,500rpm), but reduced fuel consumption and CO2 emissions. Other benefits which are provided by the new engine is an increase in smoothness as a result of a 5dB reduction in engine noise.
Key to the new engine’s clean running is the addition of Selective Catalytic Reduction (SCR) which operates under Vauxhall’s ‘BlueInjection’ banner. SCR technology requires owners to use AdBlue fuel additives to help the new diesel run cleaner – something which until now has only been necessary on vans. The AdBlue additive is required to remove harmful NOx emissions from the exhaust gases.
Stuart Harris, Vauxhall’s Head of Carline Brand, told first4auto: “This sophisticated engine makes a perfect partner for our top models, including Insignia and Zafira Tourer. It’s high power density, refinement and frugality place it among the very best diesels in its class”.
The company says that the new 2.0 CDTi is the first of a new family of large diesel engines developed by parent company, General Motors. The engines will be manufactured at the company’s Kaiserslautern engine plant in Germany. The new engine is the result of a £3.2 billion investment Vauxhall plan to make to overhaul its powertrains. Eventually, the company says there will be 13 new engines being brought to the market by 2016.
The new 2.0-litre engine will make its maiden appearance in the Insignia next year. Vauxhall refused to be drawn into providing us an answer to our question about whether the engine could also find its way eventually into the new Astra when it arrives. The engine follows the release of a range of new 1.6-litre petrol and diesel engines, as well as the 1.0-litre 3-cylinder petrol powertrain that will be available to order in the ADAM supermini from this month.
