At the Geneva Motorshow (March 7-17, 2013) Opel will introduce its all-new generation diesel engine, the 1.6 CDTI ECOTEC, in the Zafira Tourer. This new powertrain is the cleanest diesel engine in Opel’s history. Equipped with Opel’s “BlueInjection” SCR technology (selective catalytic reduction), it already meets the strict Euro 6 emissions limits. The new generation 1.6 CDTI ECOTEC unit delivers 100 kW/136 hp and 320 Nm of torque for outstanding fuel efficiency in the Zafira Tourer of just 4.1 l/100 km consumption and 109 g/km CO2. No other compact monocab on the market place offers such a great combination of high torque, performance (with a maximum speed of 193 km/h) and fuel economy. The new state-of-the-art Opel four-cylinder 1.6-liter diesel engine does not only set benchmarks for performance with its high power and torque density but also for refinement with an outstandingly low level of noise, vibration and harshness.

The new 1.6 CDTI ECOTEC diesel and its innovative engine control unit have been entirely developed in-house by a global team of engineers in Turin, Rüsselsheim and the USA. It further expands the Zafira Tourer’s broad powertrain offer. This comprises five diesel – including a new high performance 2.0 BiTurbo CDTI engine with 143 kW/195 hp – and four gasoline engines, as well as an LPG and a CNG Turbo variant. The extensive choice ensures that a wide range of customer needs and tastes are met. “Opel continues to spice up its already successful Zafira Tourer with new and exciting German-engineered technology,” says Mike Ableson, Opel Board Member and GM Europe Vice President, Engineering. “Our new generation 1.6 CDTI ECOTEC unit is not only the cleanest diesel engine in Opel’s history. It just makes our Zafira Tourer stand out once again: There simply is no other car that offers such a perfect blend of high performance, impressive fuel economy, excellent refinement and top class quality in a seven-seat layout.”

The award-winning Opel Zafira Tourer – most recently a recipient of the 2012 ‘Golden Steering Wheel’ from readers of European car magazines – combines premium class ambience and leading flexibility inside the cabin with cutting-edge technologies, some of which are unique in the segment and enhance safety and comfort. Technical highlights include the mechatronic FlexRide chassis system, the second-generation Opel Eye front camera, the AFL+ adaptive forward lighting system and a panoramic windshield which floods the cabin with natural light. Extra flexibility inside the Zafira Tourer is provided by the new generation Flex7 system, including the unique lounge seating function which gives passengers an unprecedented amount of space in the second row.

1.6 CDTI ECOTEC has class-leading refinement, performance and environmental compatibility

Featuring closed-loop combustion control and an aluminum block, the all-new 1.6 CDTI ECOTEC diesel engine starting in the Zafira Tourer at the Geneva Motor Show will replace existing 1.7-liter engines and certain lower-powered versions of the 2.0-liter range. Class-leading attenuation of noise, vibration and harshness, high power/torque density and low fuel consumption were the main development objectives. Initially maximum power and torque have been set at 100 kW/136 hp and 320 Newton meters respectively; compared to the 1.7-liter engine of the older generation, these are increases of respectively 4.6 and 6.6 per cent. Compared to similarly powerful 2.0 liter diesels in the Zafira Tourer, the fuel consumption of new generation 1.6 CDTI has been reduced by up to 10 per cent.

The Zafira Tourer 1.6 CDTI’s moderate fuel consumption and extremely low emissions – comparable to those of the gasoline-engine version – are made possible by the use of Opel’s “BlueInjection” selective catalytic reduction (SCR) system.

In this environmentally-friendly exhaust after-treatment process 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 (NOx) enters the catalyst in the exhaust gas, and is then selectively reduced to nitrogen and water.
