Honda CR-Z (2011) engine and IMA System

Honda CR-Z (2011) is the first car to combine a 1.5-litre i-VTEC engine and the IMA system, giving excellent fuel economy and great emphasis on driver enjoyment. This 114 PS engine is combined with a 14 PS electric motor which also boosts torque, with an impressive 78 Nm at low to medium engine speeds. The combined power figure peaks at 124 PS with a healthy 174 Nm of torque. Performance and driver enjoyment can be seen as a conflicting need to good fuel economy and exhaust emissions levels. The CR-Z's 1.5-litre, 16-valve, i-VTEC, petrol engine provides driver enjoyment with its enthusiastic engine note, willingness to rev and broad spread of torque. At the same time its modest capacity, boosted by an electric motor can achieve excellent fuel economy and low overall exhaust emissions, including the all important CO2 emissions. The CR-Z is the first Honda hybrid, since the original 1-litre Insight to use a four valve per cylinder head with the IMA system.
