– Chevrolet Captiva offers dual zone climate control that allows the driver and front passenger to operate separate temperature settings.

– Dual-zone climate control enables more efficient use of air-con that can help save fuel and reduce greenhouse gas emissions.

– Air-con systems used in many Chevrolet vehicles are put through high temperature testing to ensure quick and efficient operation.

BANGKOK, Thailand —— When a car sits under hot sunshine long enough its interior temperature can reach 70 degrees Celsius – hot enough to fry an egg. Thai Chevrolet owners don’t have to endure high heat for long because their vehicles’ air conditioning systems have been designed to cool down by 45 degrees Celsius in just 10 minutes – faster than many competitor models.

The new 2014 Chevrolet Captiva SUV, for sale now and coming to dealerships nationwide in June, offers dual zone climate control that allows the driver and front passenger to operate separate temperature settings. This advanced feature provides improved comfort year-round, especially during the hottest months when outside temperatures rise above 40 degrees Celsius.

Chevrolet customers stay cool and comfortable even on the hottest days because General Motors Global Product Development tests vehicle air-con systems in external temperatures up to 50 degrees Celsius.

“By testing against high heat, we help ensure that Chevrolet customers living in hot places like Bangkok, Mumbai and Arizona will have reliable air-con every time they turn it on,” said Patiparn Diloksampan, thermal passenger engineer at GM’s Rayong Facility.

Thermal testing of air-con systems typically requires driving test vehicles for thousands of miles in both real-world and simulated environments. Engineers conduct these tests at GM’s Desert Proving Grounds in Yuma, Arizona, USA, and in climatic test laboratories at its engineering centres around the world.

In both real-world and laboratory environments, vehicles are subjected to high “solar load” – the heat generated from maximum exposure to sunlight. Then the vehicles are driven at a steady speed to ensure the air-con is capable of cooling the interior to a comfortable temperature within minutes.

The longer a vehicle sits closed in hot sunshine the hotter the interior gets – much hotter in fact than the outside temperature. When it is 32 degrees C outside the vehicle interior temperature can rise to 51 degrees C in just 30 minutes, up to 56 degrees C in 60 minutes and 59 degrees C in 90 minutes. Needless to say, no person or pet animal should ever be left inside a closed car in hot weather without the air-con turned on.

Captiva’s new dual zone climate control aids more efficient cooling of its interior, particularly if the driver is alone, because he is able to minimise wasted cooling in the passenger section. By using air-con more efficiently, the Captiva driver can put less demand on the engine, which results in more efficient fuel use and fewer greenhouse gases.

The new Captiva retains its air-con outlets for the comfort of third-row occupants and seats five to seven people comfortably.

According to experts, light-coloured vehicles – interior and exterior – typically cool down more quickly than dark-coloured vehicles because darker colours absorb more heat from sunlight than lighter colours. As a result, light-coloured vehicles can be about 5 degrees C cooler than dark-coloured vehicles when subjected to the same amount of solar load. The new Captiva is available in a range of colours, including several lighter shades. Customers can choose from Switchblade Silver, Alpine White, Royal Gray, Black Sapphire and Auburn Brown.

Additionally, tinted glass can help reduce heat load inside Captiva by nearly 80 percent. Customers should ask the Chevrolet dealers about this option at the time of purchase.

Since its introduction the award-winning Captiva has been Chevrolet’s flagship product in Thailand, with over 35,000 units sold, and thousands more sold throughout the region. With the introduction of the new Captiva, Chevrolet has the most up-to-date vehicle portfolio on the market.

“Captiva appeals to those who need an SUV and want it to have an attractive exterior, luxurious interior and impressive performance,” said Gustavo Colossi, vice president of Sales, Marketing and Aftersales, Chevrolet Sales Thailand and GM Southeast Asia Operations. “With the new technology featured in the 2014 Captiva, it’s now even more suited for its customers.”
