View Here : 17 Charger Hellcat
It’s common knowledge that it’s fairly simple to get a Dodge Challenger or Charger Hellcat run nine-seconds quarter-mile. With a power boost, drag slicks and a good driver, a high nine-second pass is possible in a Hellcat despite its near 4,500 lb kerb weight.
at the top of page 3, it shows all models except Hellcat get electric assist, while Hellcat remains "performance tuned". (not a fan of electric assist) You're right, only Challenger Hellcat steering is now all electric, the Charger Hellcat remains hydraulic.
