Opel Zafira Tourer ecoFLEX : a ‘lounge’ on wheels that emits only 119 g of CO2/km

Shortly after the start of sales of the new Zafira Tourer, Opel will offer a ecoFLEXversion with extremely low CO2 emissions, a van with seven seats. Beingequipped with Start / Stop and a comprehensive package of technologiesecoFLEX Opel Zafira 2.0 CDTI ecoFLEX Tourer emits just 119 g CO2 per kilometer. Because of this feature, the car is between compact MPV with the lowest emissions, developing a power of 96 kW/130 hp and generates peak torque of 300 Nm.

Like other family members ecoFLEX ecoFLEX 2.0 CDTI Zafira Tourer contradictpreconceived idea according to which reduce fuel consumption and emissionsinevitably has a negative impact on driving performance. Zafira Tourer ecoFLEXwith 130 hp turbodiesel engine with a displacement of 2 liters, 4 cylindercommon-rail injection system with optimized control of the combustion process andreduce internal friction, consumes just 4.5 liters of diesel per 100 km in thecombined cycle test.

Top speed is 193 km / h, the van accelerates from 0-100 km / h in 11.4 seconds.The combination of efficient diesel engine and transmission system optimized six-speed manual transmission ratios higher and also contributes to the success ofwhich is kept balance between performance and consumption.

Comprehensive measures to reduce gas consumption and emissions

To reduce consumption of the new Zafira 2.0 CDTi ecoFLEX Tourer has adopteda range of measures around its engine and components, as well as body, holdingthe lead in obtaining these results. To improve aerodynamics, the body waslowered by 10 mm and grille has been integrated into active air shutter. It remains open to maintain optimum temperature at low speeds when the engine operates athigh thermal load, such as rail or road in towing mode, closing automatically at higher speeds and directing airflow around the vehicle.

This improves aerodynamics, reduce fuel consumption and CO2 emissions. Zafira2.0 CDTI ecoFLEX Tourer is equipped with 225/50 R17 tires with low rolling resistance. Gear change indicator – dial speedometer and tachometer positioned between the light – signals the driver the ideal time to change into a higher gearand helps to adopt a management style which ensures lower fuel consumption.

Efficient and Dynamic optimized engine and transmission management

Optimized engine management system, which was designed by engineers at Opelunit powered turbodiesel four-cylinder displacement of 2.0 liter common-railinjection system, which has an output of 96 kW/130 hp guarantee maximum efficiency. Maximum torque of 300 Nm is available at speeds between 1,750 and 2,500 rpm. Multiple new injection system at a pressure of 1,600 bar, improves the combustion process and reduce fuel consumption.

To reduce friction in the engine camshaft is supported by needle bearings.Cylinder pressure sensors for the glow plugs (Cleantech combustion technology)provide a very precise control of combustion. A variable flow oil pump provides oilpressure needed exactly. This is controlled by the engine control module and help reduce CO2 emissions.

Smart: in energy recovery mode engine Overspeed

To ensure optimal management of electricity, Opel introduced a recovery systemthat recovers energy during braking kinetic energy through the generator in the engine Overspeed mode, turning it into electricity to power the battery. This occursautomatically when the driver releases the accelerator pedal or brake pedalpressed. When the battery has sufficient charge, it significantly reduced the amount of electricity produced by the generator, electric consumers being fed fuel-savingmode using electricity stored.

Thus, the engine generator will not have to act upon acceleration, reducing fuel consumption and emissions. In addition, as with all Zafira models Tourer,compressor cooling system is activated via a coupler only when needed.

Efficient: the Start / Stop operation periods reduce engine idling

By the spring of 2012, start / stop system created by Opel will be available to over 30 vehicle combinations – engine, helping to improve long-term compatibility withenvironmental protection standards. The Start / Stop the engine immediatelyprovides automatic shutdown of the driver selects the gear to neutral, releaseclutch and tach needle moves Autostop special position. To restart the driver only need to switch to first gear.

A powerful battery ensures maximum reliability of the electrical system andimmediately start the engine at any time. For reasons of safety and passenger comfort, temperature control elements and vacuum brake booster phase remain active during hitchhiking. When it deems it necessary, for example in case of slowtraffic, with frequent stops and starts, the driver can deactivate the systemmanually, using switch “eco”.
