It was back in 2008 when we reported Cadillac is preparing a four-door competitor for models like Infiniti G37 and Mercedes C-Class. The car is supposed to be called ATS and will be revealed, in concept form, by the end of the year. It is still unclear if will be in October in Paris or December in Los Angeles.

According to an Inside Line source: "We're finalizing the four-door showcar of the ATS first. Then we'll follow quickly after with a wagon, a coupe and a convertible."

The ATS will replace the BLS on the European market and in the USA will be placed below the CTS. It will be built on the "Alpha" platform and will feature a rear-wheel drive system.
