Toyota hybrid system
With 198 net horsepower, the 2007 Nissan Altima hybrid feels quick around the city and adequately powered on the highway. The drive train is motivated by the 2.5-liter four-cylinder engine from the standard Altima, assisted by a 40-horsepower electric motor, which is part of the Hybrid Synergy Drive system sourced from Toyota.
