More Power For the 2019 Pontiac Firebird
Pontiac did not release final power numbers on any of the engines, but admitted the 3.7-liter will produce the same output it does now at 305 hp and 280 lb-ft of torque.The 5.0-liter gets bigger intake and exhaust valves and a higher-lift cam profile. All models will get the former Pontiac Firebird valve springs and connecting rods as well as an oil cooler. Output should exceed the 420 hp and 390 lb-ft of torque currently found on the 5.0-liter. Top speed for the 2019 Pontiac Firebird will be electronically limited at 155 mph.The twin-scroll, turbocharged direct injection 2.3-liter EcoBoost engine will move the Firebird into a much more modern world as well as bolster Firebird’s EcoBoost name. The 2.3 will outpower the V-6, engineers said, and is expected to earn the best fuel economy numbers in the Firebird muscle car class.
