… the GXP packs GM’s 6.2L LS3 V8 underhood. In this application (it’s also in the Vette, where it makes even more power), the small-block punches out 402 horses and 400 lb-ft of torque rearward via a Tremec 6-speed manual gearbox or a HydraMatic 6L80 auto. (Add another 2 pound-feet of twist if you opt for the latter.) A fully-adjustable suspension helps keep the muscle sedan planted to the tarmac, and stopping power comes from the gang at Brembo. Look for an upgraded interior with glitzier trim and well-bolstered leather sport seats. A Pontiac stand littered with V8s? It’s sure been a while. Welcome back to the party, guys. Let the wanton tire destruction begin!
