Leftlane News has spy photos of the upcoming Opel Insignia hatchback, which is expected to be unveiled this summer in London. While the Insignia sedan will be built in the U.S. and sold in North America as the Saturn Aura, industry analysts don't expect this model to make its way onto our shores, but that doesn't mean it won't happen.

Late last month Leftlane News published spy photos of the next-generation Buick LaCrosse, which will be built on the same GM global midsize architecture as the 2010 Saturn Aura.

General Motors recently demonstrated its progress on developing a future advanced engine technology for consumers that squeezes more miles per gallon of gas and reduces emissions.

While Saturn's overall sales were down 15.5% to 16,888 units last month, sales of the brand's Aura midsize sedan and Vue sport-utility saw healthy increases from a year-over-year perspective.

With photos of the Opel Insignia sedan – which also is believed to strongly hint at the next-generation Saturn Aura – officially released, the Motor Authority offers its interpretation of what we could expect the model's coupe and wagon variants to look like.
