Environmental care is one of the core values at Volvo Car Corporation.
That is why we were faced with an extra-tough challenge when Volvo developed the Volvo XC90, since SUVs are relatively large vehicles with powerful engines.
"We know that many of today’s SUV owners are uncomfortable about the fact that their vehicles produce higher emissions and consume more fuel than most passenger cars do," says Hans Wikman, the Project Director behind the development of the Volvo XC90.
ULEV and ULEV II
The Volvo XC90 will take the lead in the SUV segment as regards both fuel economy and emissions. The 6-cylinder petrol engine meets the American ULEV (Ultra Low Emission Vehicle) requirements, while the 5-cylinder petrol engine already meets ULEV II, a standard that does not come into force until model year 2004.
What is more, the Volvo XC90 meets these standards in 50 American states, a clear demonstration that Volvo Cars regards the environment as equally important everywhere.
In Europe, the petrol engines in the Volvo XC90 already meet the Euro 4 requirements, which come into force in the year 2005.
The new Volvo Cars 5-cylinder diesel engine is among the very cleanest on the market today, offering top-class fuel economy.
The low emissions and the low fuel consumption have been achieved through a number of interacting factors. Here are a few examples:
Interior Air Quality System
The Volvo XC90 also takes care of the environment inside the passenger compartment itself. The climate unit can be supplemented with the automatic IAQS or Interior Air Quality System.
IAQS consists of a filter and a sensor. The former features a particle trap and an active carbon filter, removing particles such as pollen and unpleasant odours from the incoming air.
The sensor monitors the presence of substances such as nitrogen oxide, carbon monoxide and hydrocarbons in the air entering the cabin. If concentrations are high, the recirculation function is automatically activated to prevent these pollutants from entering the passenger compartment. The system thus contributes to cleaner air inside the vehicle and reduces the risk of allergy-related problems.
Ökotex and PremAir®
All the textiles and leather used in the Volvo XC90 are certified according to Öko-Tex standard 100. Öko-Tex is a European standard used throughout the world, which safeguards that the textiles are free from hazardous and allergenic substances. Furthermore, the leather is tanned using natural plant substances and the interior door handles have a surface treatment that does not allow nickel contact with the skin.
PremAir®‚ is the name of Volvo’s renowned "ozone-eater", and it is an important part of the overall environmental compatibility of the Volvo XC90. Ground-level ozone is formed through the combination of air pollutants and strong sunlight. It can cause respiratory problems in human beings and it also inhibits plant growth.
Volvo was the first carmaker in the world to tackle the problem of ground-level ozone, with the introduction of PremAir®‚ in 1999. The car’s radiator is coated with a thin catalytic film that converts up to 75 percent of the ground-level ozone, as it passes through the radiator, into oxygen.
