Part of Opel's environmental strategy includes the introduction of low-emission ecoFLEX versions in Opel/Vauxhall's high-volume model lines. These cars combine economy and driving fun with low consumption and reduced CO₂ emissions. The premiere model in the Opel/Vauxhall ecoFLEX range is a Corsa 1.3 CDTI, which produces just 119 g/CO₂ per kilometer. The Corsa ecoFLEX debuts at the IAA 2007 and is available from 2008.

Natural gas is another alternative fuel. Opel currently offers two models ex works with this especially environmentally friendly and economical form of propulsion: the Zafira CNG and Combo CNG (Compressed Natural Gas) consume just 5.0/4.9 kg of natural gas per 100 km (138/133 g CO₂/km respectively). The seven-seat Zafira CNG emits just under 20 g CO₂ per kilometer and seat.

New Agila: Friendly, dynamic, flexible

• Format: Five doors, five fully fledged seats
• Function: Versatile thanks to practical details
• Design: Balanced proportions, distinctive lines
• Powertrain: Two gasoline engines, one turbo-diesel, automatic transmission

With five doors and five seats, the new Opel Agila is not only as practical as its predecessor, which sold around 440,000 units across Europe, but is now also much more dynamically designed. The smallest Opel makes its market debut in spring 2008 and boasts Opel-typical balanced proportions, soft curves and a distinctive side graphic. Passengers still sit high and upright, but the roofline has been dynamically lowered and now blends into a smooth arc toward the rear. This helps create the Agila's aerodynamic drag coefficient of 0.35 – a relatively low figure for a vehicle of this size. The urban car is now 20 centimeters longer, six centimeters wider, but seven centimeters lower than its predecessor.

The entry-level engine is an almost one-liter, four-valve, three-cylinder unit that produces 48 kW/65 hp. The 1.2-liter four-cylinder unit produces 63 kW/86 hp and is available with an automatic transmission for the first time. The most economical engine in the Agila range is the 1.3-liter common-rail turbo-diesel, which produces 55 kW/75 hp.

Model year 2008: Greater selection and more extensive equipment

Opel goes into model year 2008 with a lot of innovations and presents a fresh, cutting-edge product portfolio. The most important enhancements include the considerably higher level of equipment for the Vectra, Vectra station wagon and Signum. The 206 kW/280 hp top performers Vectra OPC and Vectra station wagon OPC are available with a six-speed automatic transmission for the first time. In the Corsa range, the 110 kW/150 hp Corsa GSi fills the gap between the Corsa Sport and the Corsa OPC.

Other additions include:

• Corsa 1.3 CDTI now also with Easytronic transmission
• Antara 2.0 CDTI with 127 hp and diesel particulate filter
• New special edition Astra TwinTop model "Endless Summer"
• New light alloy wheels, more versatile infotainment systems, fresh colors
