HENNESSEY FORD FOCUS RS
Ford's popular hot hatch is no slouch to begin with, cranking out 350 hp. Obviously someone thought that wasn't enough. The Hennessey Ford Focus RS boosts the output of the 2.3-liter EcoBoost engine to over 400 hp, thanks to a software upgrade, new high-flow air filter, and a new stainless exhaust mid pipe. The HPE400 upgrade will also come with special badging, and can be installed DIY or by the company, who will through in a dyno tune, as well.
