Cars / Dodge Challenger / Charger SRT8

Dodge Challenger / Charger SRT8 (2006–2015)

LX / LC · 6.1L Hemi (06–10) · 6.4L 392 (11–15)

Verdict: Big power, big brakes, big thirst. Prefer documented cooling and driveline care; know that 6.1s skip MDS while later 6.4 automatics bring MDS lifter homework.

Notes

Challenger SRT8 US volume starts 2008; Charger SRT8 from 2006. Same Hemi family lessons.
392 (2011+) cars are quicker and thirstier — price consumables in.
