The hybrid Q50--Infiniti does offer it a unique name--features the same powertrain
found in the M35h, where the electric motor is built into the car’s seven-speed automatic transmission and powered by an array of lithium-ion batteries. Two electronically-controlled clutches allow the full decoupling of the V-6 when the car is in electric drive and power regeneration modes, helping to reduce mechanical drag and boost the efficiency of the electric motor.
Peak output of the hybrid Q50 is the same as that of the M35h, registering at a combined 354 horsepower (296-hp V-6 plus a 67-hp electric motor), which should make this one of the quickest accelerating hybrids on the market.
No specs have been announced but with a smaller--and presumably lighter--body than the M35h, look for better performance in the Q50. The M35h does the 0-60 mph sprint in around 5.5 seconds and is capable of returning 27/32 mpg city/highway 29 mpg combined.
