Our spies have caught on camera the second generation Opel Insignia stretching out in the Alps together with the outgoing model.

Although it has the production body, you will notice the prototype is carrying an extensive amount of camouflage with some very thick plastics painted in the same color as the body panels to try and fool us. That being said, the more dramatic roofline is visible from a mile away and should give the new mid-size model from Opel a considerably sleeker silhouette.

Almost a year ago we heard Opel design director Malcolm Ward saying the new Insignia will be "one of the most beautiful cars you will have seen in years", adding that "it's absolutely gorgeous." The Rüsselsheim-based automaker has already confirmed the model's styling is going to be influenced by the rather stunning Monza concept showed exactly two years ago at the 2013 Frankfurt Motor Show.

Rumors say the next generation will grow in size by around 10 centimeters, with most of the added length probably ending up in the wheelbase to enable a more spacious cabin which is exactly what the doctor ordered since the outgoing Insignia has been heavily criticized for being cramped inside.

Despite getting bigger, Opel's Passat fighter will ride on a new platform that will bring an estimated weight loss of up to 200 kg (441 lbs). Once again, this is very good news as another bad thing about the current car is its hefty weight.

The next generation Insignia will be sold as an Opel, Vauxhall, Buick and also as a Holden. It should be out in the second half of next year as a 2017MY.
