Just thought it was interesting.

Replacing those two engines is a single 3.6-liter V-6. “This is the engine the SRX should have had all along,” said an engineer who didn’t wish to be named. The engine is similar to the 3.6-liter V-6 found in the CTS, but it’s adapted and tweaked for the SRX’s transverse arrangement. A few of the changes—like the clever exhaust manifolds integrated into the heads, the plastic intake manifold, and lighter connecting rods—help shave 20 pounds off the 3.6-liter V-6. Lightening the connecting rods allows the engine to rev a bit higher, and the higher revs lead to 308 hp at 6800 rpm. Other changes, like additional sound deadening in the firewall and a clever rubber-isolated high-pressure fuel line, keep engine noises out of the cabin. Putting rubber between the fuel line and engine nearly eliminates the injector ticking sound we’ve come to expect from direct-injection engines at idle.
