We recently came across some interesting information from a credible source about future products for GM’s Chevrolet and Cadillac brands, and which to some extent, are interconnected.

We’ll begin with Chevrolet as we learned that the Corvette’s immediate future includes a more potent version of the 4.5-liter twin-turbocharged and direct-injection engine that GM debuted on the Cadillac Elmiraj Concept just last month.

We’re told that the new V8 will most likely be used in the successor of the Z06, rumored to be called Z07. While in the Elmiraj, it produced an estimated 500hp, in the Corvette, it could push out as much as 600 horses (unconfirmed).

The other piece of information we received is also loosely related to the Elmiraj, as the concept was designed to hint at Cadillac’s upcoming, but as of yet, unnamed flagship series that will rival Germany’s finest, and by that we mean, the Audi A8/S8, BMW 7-Series and Mercedes-Benz S-Class.

We learned that it’s arrival in the market in sedan form has been confirmed for 2016, with available powertrains to include a new 3.0-liter turbocharged V6 as well as the current 3.6-liter turbocharged V6, which produces 420hp in the CTS V-Sport. While nothing was mentioned, we can’t imagine a range-topping Cadillac without a V8, so the turbocharged unit we mentioned earlier should also be available.
