2018 Dodge Challenger SRT Demon

摘要

Remember how Dodge's new-for-2015 Challenger and Charger SRT Hellcats were headline grabbers with their 707-bhp supercharged Hemi V-8s? Now that's yesterday's news, and the story Dodge is selling for 2018 stars an 840-horsepower Challenger. Let that 840 number soak in as we consider the latest Future Collectibles pick, the 2018 Challenger SRT Demon.It's probably best not to bury the 840-horse lead here, so let's start under the hood. As in the Hellcat, the engine is Dodge's supercharged 6.2-liter V-8. But in Demon trim, Dodge says the Hemi is 62 percent new. Highlights include a unique block, crankshaft, pistons, and connecting rods, in addition to a larg-er blower, increased boost pressure, a higher redline, bigger fuel injectors, and even a second fuel pump. The engineers also fitted the "SRT Power Chiller," basically an intercooler that uses the refrigerant from the car's air conditioner to cool intake air. Horsepower is rated at 840 on 100-octane unleaded gasoline, or 808 ponies on easily sourced 91-oc-tane premium. Torque peaks at 770 or 717 pound-feet, depending on what's in the tank.
