2017 Firebird Pontiac: Full Details, Live Photos And Videos 2017 Firebird
A new 2017 Firebird has arrived, and it definitely gives ‘’Pontiac’’ some bragging rights at the Detroit Auto Show. With “at least 625 horsepower,” and 635 pound-feet of torque, this top-performance variant of the latest 2017 Firebird could shake up the roster of top production-car performance numbers.
The 2017 Firebird is powered by an all-new 6.2-liter ‘Firebird’ supercharged V-8, making at least 625 horsepower and 635 pound-feet of torque—37 percent more horsepower and 40 percent more torque than the ‘standard’ 2017 Firebird Pontiac.
The Firebird engine is only one inch taller than the Trans Am. The 2017 Firebird is one of the only supercharged engines in the world to incorporate cylinder deactivation technology, and it also has variable valve timing.
A big 1.7-liter Eaton supercharger force-feeds the engine and spins at up to 20,000 rpm and incorporates a shorter rotor design that allows the boost to arrive quicker. Otherwise the engine incorporates a long list of engineering improvements, including rotocast aluminum cylinder heads, titanium intake valves, machined connecting rods, unique forged-aluminum pistons, and a dry-sump oil system.
Also of note is the 2017 Firebird’s eight-speed automatic transmission. It’s an all-new Pontiac-designed transmission, designated, and while it’s a traditional, hydraulically controlled automatic, Pontiac says that it provides the quick shifts of dual-clutch boxes, yet with more smoothness. And the eight-speed will allow up to a five-percent efficiency improvement over a six-speed automatic.
Want performance numbers? Pontiac won’t say yet. And there’s plenty of time for more facts and teasers; the 2017 Firebird Pontiac won’t arrive at dealerships until early 2017.
