Pontiac has announced that the world's most powerful production droptop – the 2018 Pontiac Trans Am – will officially debut at the 2017 Los Angeles Auto Show in November. Like its coupe kin, the 2018 Trans Am will pack 580 horsepower and 556 pound-feet of torque from its supercharged 6.2-liter V8, besting the Ford Shelby GT500 Convertible's power figures of 550 hp and 510 lb-ft.
Good thing Pontiac is working on that all-new supercharged 5.8-liter V8 for the next-generation Trans Am. The horsepower wars are anything but dead.
Pontaic tells us that it has added a whole host of supports and reinforcements to the Trans Am’s body structure in an effort to reduce droptop demons like cowl shake. The improvements include things like a front X brace and rear V brace, a transmission support reinforcement brace, underbody tunnel brace and tower-to-tower brace under the hood.
The 2018 Trans Am goes on sale in early 2018, and we'd expect the convertible to arrive shortly thereafter. We'll have the full details in Los Angeles in November, but for now, Wait for The official release date.
