Opel Zafira Tourer ecoFLEX: Lounge on Wheels with just 119 g/km CO2
*Economical and agile: Master of versatility easily manages balancing act
*Effective: Start/Stop-System and ecoFLEX technologies for lower fuel consumption
*Powerful: Efficient 2.0 CDTI turbo diesel with 96 kW/130 hp and up to 300 Nm
Rüsselsheim. Shortly after the new Zafira Tourer goes on sale in the fall, Opel will also offer an especially low CO2 ecoFLEX version of the seven-seat monocab. Equipped with Start/Stop and a comprehensive package of ecoFLEX technologies, the new Opel Zafira Tourer 2.0 CDTI ecoFLEX emits just 119 g/km CO2. This makes it one of the lowest-emission compact monocabs while featuring output of 96 kW/130 hp and maximum torque of 300 Nm.
Just like its ecoFLEX siblings, the Zafira Tourer 2.0 CDTI ecoFLEX puts to rest the preconception that low consumption and emissions inevitably have a negative impact on driving performance. The Zafira Tourer ecoFLEX with the 130 hp, 2-liter, four-cylinder-common-rail turbodiesel featuring optimized combustion control and reduced internal friction consumes just 4.5 liters of diesel per 100 km in the combined cycle. Maximum speed is 193 km/h and the monocab reaches the 100 km/h mark in 11.4 seconds. The combination of efficient diesel engine with optimized and wider-ratio six-speed manual transmission also contributes to it successfully managing the balancing act between performance and consumption.
Comprehensive: Measures to reduce consumption and emissions
A whole range of measures undertaken on and around the engine as well as on the body plays a large role in the new Zafira Tourer 2.0 CDTI ecoFLEX’s reduced consumption. For improved aerodynamics, the body is 10 mm lower and an active aeroshutter is integrated in the radiator grille. While it remains open to maintain optimal temperature at low speeds and when the engine is running under high thermal load such as on inclines and when in towing mode, the aeroshutter automatically closes at higher speeds and directs driving wind around the car. This results in improved aerodynamics, lower fuel consumption and lower CO2 emissions. The Zafira Tourer 2.0 CDTI ecoFLEX has 225/50 R17 low-rolling-resistance tires. The shift indicator – an illuminated gauge located between the speedometer and revolution counter – signals the driver the ideal moment to shift up and helps to adapt to a fuel-saving driving style.
Efficient and dynamic: Optimized engine and transmission management
The optimized engine management system, which was designed by Opel engineers for the four-cylinder 2.0-liter common-rail turbodiesel unit with 96 kW/130 hp, guarantees top efficiency. Maximum torque of 300 Nm is available at 1,750 - 2,500 rpm. The new multiple injection system at 1,600 bar improves the combustion process and reduces consumption. To reduce friction in the engine, the camshaft is supported by needle bearings. Cylinder pressure sensors in the glow plugs (Cleantech Combustion Technology) enable very accurate combustion control. A variable displacement oil pump delivers only the necessary oil pressure. This is controlled by the engine control module and helps to reduce the CO2 emissions.
Intelligent: Energy recuperation in engine overrun mode
To ensure optimum electrical energy management, Opel introduces a braking energy recuperation system which recovers kinetic energy via the generator in engine overrun mode, converting this to electrical energy and feeding it into the battery. This happens automatically when the driver takes his/her foot off the accelerator pedal or presses the brake pedal. When the battery is sufficiently charged, the generator output is greatly reduced and the electrical energy consumers are powered in a fuel-saving manner by the buffered electrical energy. This relieves the engine from having to drive the generator when accelerating and thus reduces consumption and emissions. In addition – like in all Zafira Tourer models – a clutch only activates the air conditioning compressor when it is actually needed.
Effective: Start/Stop system reduces engine idling
The Start/Stop system developed by Opel will be available more than 30 vehicle-engine combinations by the spring of 2012, helping to improve long-term environmental compatibility. With Start/Stop, the engine stops automatically as soon as the driver shifts into neutral, releases the clutch and the rpm needle moves to the special Autostop position. The driver then just shifts into first gear to drive off again. A powerful battery ensures maximum reliability of the electrical system and immediate engine start-up at all times. For reasons of safety and passenger comfort, temperature controls and the brake booster vacuum control remain active during the Autostop phase. When deemed necessary, for instance in slow-moving stop-and-go traffic, the driver can manually deactivate the system with the “eco” switch.
