The Volkswagen Polo 66TDI Comfortline has been declared by Australia's largest automative brand Carsguide as Australia's best energy efficient car. It received the 2010 Best Green Car award from Carsguide.

The Volkswagen Polo has narrowly beaten the first Australian built hybrid, the Toyota Camry. Volkswagen Polo had also picked up the 2010 Carsguide Car of the Year award last week.

"Aside from being the most frugal car in terms of fuel consumption, the Volkswagen Polo was felt by most to best satisfy all of our requirements," said Carsguide managing editor Ged Bulmer.

"The Volkswagen is proof you do not have to sacrifice style, safety or driving dynamics in the quest for lower emissions... In the context of Best Green Car, the Polo TDI's emissions are a low 124 grams of CO2 per kilometre."

Other finalist contenders for the 2010 Carsguide Best Green Car award were the first Australian-built hybrid Camry Hybrid, Holden Barina Spark and the Holden Commodore VE Series II E85.

Bulmer said that the Camry Hybrid was a pleasant surprise in Carsguide Green Car contest with its remarkable fuel efficiency, strong performance, outstanding refinement and high safety levels.

"As the first Australian-built hybrid, it also represents an important dawn for local manufacturing of a technology that will only become more widespread," said Bulmer.

Carsguide's judging panel of nine motoring experts carefully assessed each of the cars in areas of: fuel consumption, type of fuel and cost, CO2 emissions, impact on gross emissions, value, safety, technology and function. Previous winners of the Carsguide Best Green Car Award were the Ford Fiesta ECOnetic in 2009, the Audi A3 TDIe in 2008, the Ford Falcon G6E Turbo in 2008 and the Hyundai i30 CRDi in 2007.
