This is big news, indicative of the downward trend in sedan sales that are giving rise to all sorts of new creations from automakers, usually of the SUV variety or of small cars that are badged as such. For those a bit hazy on a five-door hatch, bear in mind that it’s not the same as a Volkswagen Golf with four doors and a rear hatch. Rather, the Opel Insignia Grand Sport offers a large trunk opening similar to that of a Tesla Model S, essentially a hatchback opening that retains the rear lines of a sedan. On the other hand, the Opel Insignia Sports Tourer is a full fledged wagon. According to the report, both will be debuted in the US as 2018 models on April 4th, a week ahead of the New York Auto Show.
