It's taken 88 years for Volvo to become a true luxury brand

For most of Volvo's 88-year history, the Swedish automaker offered its loyal legions of customers well-built, safe, and practical transportation with a certain Scandinavian flair. Now, the company's diving head on into the world of luxury cars.

On the heels of the hugely successful introduction of the XC90 luxury SUV, Volvo is ready to introduce its new flagship luxury sedan - the S90. The new S90 will replace the company's S80 sedan. Although still a nice car, the current S80 has been on sale with minimal revision for nearly a decade. It is certainly showing its age. Furthermore, the conservatively styled S80 hasn't been able to drum up the big sales figures Volvo would like to see from the model.

As we await the arrival of Volvo's new S90 luxury sedan, have a look back at the company's flagship four-door sedans. Although they may not have always been overly luxurious, Volvo has always offered a big executive ride for those who sought the experience.
