Dodge has been on something of a farewell tour for its Hemi V8 muscle cars. It has built a series of "last call" versions of the Charger and Challenger, limited editions with callback paint colors and retro liveries that refer to muscle-packed Dodges of old. Now it really is getting ready to end the car design and is doing so with a bang, via the 2023 Challenger SRT Demon 170, a production car so fast it can even show a Tesla Model S Plaid a clean pair of shoes with a 1.66 second 0-60 mph time.
Dodge's engineers have performed quite a bit of work under that bulging "Air-Grabber" hood compared to lesser Demons. There's a new supercharger with a larger throttle body and a pulley that increases boost pressure by 40 percent compared to the Challenger Hellcat Redeye Widebody.
You'll get the best results by feeding it E85 (a blend of 85 percent ethanol and 15 percent gasoline); on this fuel, the Demon 170 generates an enormous 1,025 hp (764 kW) and 945 lb-ft (1,281 Nm). On the more common E10 fuel, the engine will generate a slightly milder 900 hp (671 kW) and 810 lb-ft (1,098 Nm).
