Opel launches new ecoFLEX Corsa and Astra

Not to be mistaken with Ford’s own ECONetic range or Renault’s ECO2 line of fuel-efficient models, General Motors’ European division Opel (Vauxhall) has launched the first models under its new ecoFLEX banner. Similar to GM’s own XFE line, the new ecoFLEX range represents the most fuel-efficient models in Opel’s lineup and currently includes the Corsa and Astra line of cars.

The new Astra ecoFLEX with a 1.7L turbodiesel engine produces just 119g of CO2 per km and has a fuel consumption rating of 51.3mpg (4.5L/100km). The engine still develops a reasonable 110hp (82kW) and 192lb-ft (260Nm) of torque.

Opel’s engineers have achieved extra efficiency from the standard diesel drivetrain by fitting a taller axle ratio, optimising the engine management system and reducing the engine’s idle speed. Furthermore, the ecoFLEX’s kerbweight has been reduced by 30kgs, while aerodynamics have been improved by lowering the suspension, modifying the front air intakes and fitting a drag-reducing lower engine compartment panel. Engineers also reduced the power steering pump’s idle speed and fitted 15in low-rolling-resistance tires.

Joining the Astra is an ecoFLEX version of the Corse 1.3L CDTI diesel hatch. Its engine produces 75hp (55kW) and 125lb-ft (170Nm) of torque, and returns a fuel economy rating of 57.4mpg (4.1L/100km).

Opel has plans for even more ecoFLEX models, including a version of the new Insignia sedan, which is due next year.
