Initially, the Kluger was a regular, non-hybrid SUV driven by an internal combustion engine, but later Toyota introduced a hybrid version, the Kluger Hybrid that utilizes the company's Hybrid Synergy Drive technology combined with the company's 3MZ-FE 3.3-liter V6 engine offered in either FWD or AWD trim. The hybrid drivetrain was unveiled at the 2004 North American International Auto Show, and was offered to the public in July 2005 as a 2006 model. The power steering pump, water pump and AC compressor were changed from belt-drive to electrically powered versions. A modified alternator was incorporated into the hybrid system.
