Opel has pulled the curtains off the new 2011 Opel Astra Sports Tourer, ahead of a planned public debut at the Paris Motor Show in October. Along with the car, Opel is introducing a new 1.4-liter turbocharged petrol engine that produces either 118 horsepower or 138 horsepower.

Eight different petrol and diesel engines will be available on the Sports Tourer. At the top of the diesel lineup is a 2.0-liter CDTI unit that delivers 158 hp and up to 380Nm of torque when the overboost function is enabled. Transmission options include a six speed manual and a six speed automatic gearbox. Cars with the manual transmission will get an indicator light that inform the driver of the most fuel efficient shift points. Start/Stop will also be used across the range to further aide fuel economy.

Behind the C-pillar, the car has a roofline that is subtly tapered. This allows the car to maintain cargo space of 1,550 liters. With the rear seats down, the load length of the cargo area is a full 1,835mm, longer than the entire wheelbase of the Smart ForTwo. The Astra Sports Tourer is meant to share some of the same design features as the Opel Insignia.
