If you like your engines supercharged, then Chrysler may have the vehicle for you. An intrepid photographer from Automotive.com caught a peek at the 2015 Dodge Challenger, which is rumored to carry a new 6.2-liter Chrysler Hemi V-8 “Hellcat” engine.
A286 stainless steel is used in supercharger components, because of its high tensile strength and excellent creep strength. It can handle temperatures of between -320F and 1500F, and it has top-notch corrosion strength even in aqueous environments. The supercharged Hellcat engine is expected to produce up to 640 bhp, which is similar to the 8.4-liter V-10 engine that propels the SRT Viper. That amount of bhp would also surpass the power of the Chevrolet Camaro ZL1.
More power, of course, means that cars use more fuel. Some manufacturers are working to create superchargers that do a better job of maximizing fuel efficiency. These advances would enable superchargers to be added to small vehicles and hybrids. Chrysler may move away from high-horsepower engines as U.S. fuel economy standards tighten up. But for now, expect Hellcat to hit the manufacturing floor in mid-2014.
