LUTON, UNITED KINGDOM – Feb 14, 2013: Vauxhall’s Zafira Tourer MPV will be the first model to feature the new generation 1.6 CDTi Start/Stop diesel engine, the first engine announced in a new family of state-of-the-art, four cylinder diesel units.

With its world premiere at the Geneva Motor Show next month, this cutting-edge powertrain is Vauxhall’s cleanest diesel engine ever and is equipped with BlueInjection selective catalytic reduction (SCR) technology that meets strict Euro 6 emissions regulations.

Strong and powerful, the 1.6 CDTi unit delivers 136PS and 320Nm of torque while also offering outstanding fuel efficiency of 68.9mpg combined and 109g/km CO2. This allows the Zafira Tourer to offer a combination of high torque, performance (with 0-60mph in 10.4 seconds) and fuel economy.

Available in the summer and featuring closed-loop combustion control and an aluminium block, this new four-cylinder 1.6-litre diesel engine is not only the benchmark for performance with its high power output and torque density but also for refinement with low levels of noise, vibration and harshness. It was developed entirely within GM by a global team of powertrain engineers.

Further expanding the Zafira Tourer’s broad powertrain offer, the range now comprises five diesels, including a new high performance 2.0 BiTurbo CDTi engine with 195PS, and two petrol engines.

“Vauxhall continues to develop its award-winning model range with new and exciting technology,” said Duncan Aldred, Vauxhall’s Chairman and Managing Director. “This new powertrain is Vauxhall’s cleanest diesel engine in its illustrious 110 year history.”

SCR is an environmentally-friendly exhaust after-treatment in which a harmless diesel exhaust fluid named AdBlue, consisting of urea and water, is injected into the exhaust gas. The solution decomposes into ammonia, which is then stored on a catalyst substrate. Nitrogen oxide enters the catalyst in the exhaust gas, and is then selectively reduced to nitrogen and water.
