Prototypes of the 2016 Opel Astra have been spied once again, this time undergoing final testing during the night hours.

Just like in our previous batch of spy shots, the bodies of the cars were fully camouflaged but Opel decided to remove the disguise on the headlights and taillights, giving us the chance to better look at those LED clusters. Both front and rear lighting units appear to have a high-tech design, especially the headlights while the taillights send a Seat Leon vibe.

Despite the heavy camo, it's easy to notice the new Astra will keep just about the same proportions as the outgoing model and will reportedly ride on the D2XX platform shared with the Buick Envision and the new-gen Chevrolet Cruze (China-spec). Expect a weight loss between 50 to 100 kg while the Watts rear suspension could be replaced with an independent layout.

Set to be built exclusively outside German borders, the new Astra will get Opel's latest engines such as the 1.6 CDTI with 136 HP & 320 Nm from the Mokka and a 200 HP 1.6 SIDI Turbo. A range-topping OPC version has already been confirmed for a 2017 launch with an estimated 284 HP output.

An official reveal is likely scheduled for September at the 2015 Frankfurt Motor Show and production will commence around the same time in Ellesmere Port, UK and Gliwice, Poland. Opel will offer the new Astra in the regular body styles: hatchback, wagon, coupe and sedan (not necessarily in this order).
