Opel has launched a new eco-friendly version of its five-door Astra compact hatch that returns a total fuel consumption of 76 mpg. Under the hood, the 1.7-liter CDTI turbodiesel engine produces 130hp and 221 lb-ft of torque mated to a six-speed manual transmission. As a result, the new Astra ecoFLEX consumes only 3.7-liters of fuel per 62 miles, making it more fuel efficient during the constant gas price fluctuations.

Technologies such as brake energy recuperation, low resistance tires and active aerodynamic components have all contributed to the car's eco-friendliness. The Astra will also receive an F1 KERS-like system which recovers lost energy when coasting or braking to the battery, allowing the alternator to be shut down when not required. The AC unit is only driven when needed and the LED daytime lights conserve energy as well. Pricing for the Astra ecoFLEX will be announced this fall, when the new Astra is scheduled to go on sale.
