At 350 hp, one would assume the Ford Focus RS has more than enough power for a hatchback. However, the team at Hennessey Performance decided to take it upon themselves to go one step further and offer the HPE400 package. Reaching 405 hp along with 425 lb-ft of torque, the 2.3-liter EcoBoost engine gets a major overhaul. By altering the ECU, adding a high-flow air filter and updating the stainless steel pipes and exhaust, the tuners hope to sell the full performance pack soon, complete with special exterior badging.
