Weekly Treasure: 2009 Pontiac G8 GXP

The G8 GT’s 6.-liter V8 with 361 hp was a sizeable improvement but the G8 GXP, released for 2009, was the one particular to get. Why? For two critical motives: the larger and much more powerful 6.two-liter LS3 V8 and that manual gearbox alternative the frequent GT was slushbox-only. This was the very same 402-hp V8 and Tremec manual used in the C6 Corvette.

Performance was outstanding with a -60 mph time of 4.five seconds and a quarter-mile sprint of thirteen seconds flat at 109.6 mph. Aside from the far better motor, the GXP was equipped with an upgraded suspension, more substantial ventilated Brembo disc brakes, and a phony rear diffuser (hey, it seemed interesting).
