Based on internal platform codes, sources are telling us Cadillac is working on a Delta based Mercedes CLA rival.

General Motors has spent significant time and effort refining the Delta platform-- as noted in our Cruze review this platform is well worthy of premiums above the Cruze's $17, 495 MSRP.

Based on what sources are sending our way it looks like General Motors is planning exactly that, a premium vehicle based on the new D2XX platform.

Internal program code D2JL has shown up inside the Renn Center-- D indicating Delta, 2 indicating evolution or generation number, J indicating hatch and L indicating Cadillac.

It's unclear however if the hatch is planned with traditional hatchback proportions, or more of a liftback style like the new Volt.

We were told GM believes they can get a $6,000-9,000 premium for the Cadillac versus the D2XX Cruze.

Another source tells us the cute Caddy is likely to show up with a 1.5T as the volume engine, with the 2.0T doing duty in the upper trims. Both motors are expected to make use of an 8-speed automatic, manual unlikely.
