Nissan has introduced a brand new hybrid drivetrain which is made up by a 2.5 liter four-cylinder gasoline engine, an electric motor as well as a lithium-ion battery pack. The interesting bit is that the 2.5 four potter is supplemented by a twin-screw supercharger.
This helps the new system to produce almost similar horsepower and torque figures as the company’s VQ35 3.5 liter V6 unit. This means we are talking about approximately 260 hp and 338 Nm of torque. At the same time, fuel consumption is lower too, at least 10% lower with the continuously variable transmission. Engineers claim that the new system has plenty of low and mid-range torque.
This drivetrain will either be made available alongside the 3.5 liter V6 or it might replace it all together. It is expected to be introduced into the North American market by 2013 and many suggest that it could in the next-generation Nissan Altima.
