As reported on HOMEPAGE
In addition to the new 2012 Camaro options/features
revealed a few days ago, it seems there may be a new V6 engine in the future of Camaro. Labeled the "LFX", it seems to be a significant improvement on the already outstanding LLT V6 found in LS and LT Camaros.
The new engine option description is: "LFX 3.6L SIDI, DOHC, VVT, E85 MAX, Alum GM
The LFX should displace 3.6L, like the current V6 found in the Camaro. And it's packed to the brim with advanced technologies like Spark-Ignition Direct-Injection, Dual Overhead Cams, Variable Valve Timing, and E85 capability!!
Those are the hard details...but a little research raises some other interesting points. It is likely that the LFX is going to build on the innovations of the 3.0L LF1 V6 found in vehicles like the Cadillac CTS, SRX, and Chevy Equinox. That engine features a composite intake manifold, integrated exhaust manifolds and optimized NVH/airflow treatments.
When the LLT was transplanted from the CTS into the Camaro, it picked up 8hp, or 2.6% because of different intake/exhaust efficiencies. The LF1 produces 270hp in 3.0L form in the CTS. If we scale up the displacement of the 3.0L engine to 3.6L, and use the same 2.6% power increase as the LLT, estimates have the new LFX producing anywhere from 325-330 hp when used in our favorite pony car!!
Here's some interesting documents on the LF1 (current CTS/SRX/Equinox engine) for your reading pleasure:
