Infiniti G20 / Q40 / Q60 is a G-series of mid-size prestige cars from Japanese manufacturer Nissan Motor Co., Ltd. The car was manufactured from 1990 to 2014, with the exception of the period 1996-1998. The base for the 1st and 2nd generation models was Nissan Primera, for the 3rd (designed for the European market) – Nissan Skyline. In total, four generations of the model were produced. The car was produced in three body modifications: sedan G20 and Q40, coupe (starting from the 3rd generation) and the Q60 convertible (4th generation).
The concern has been producing gasoline engines Mercedes M274 with a volume of 1.6 and 2.0 liters since 2011 and installs them on cars with a longitudinal engine, such as C-class and E-class. Similar motors for models with a transverse arrangement of the unit have the M270 index.
Nissan’s 3.0-litre VR30DDTT engine (or VR30 for short) was first introduced in 2015 as the main powertrain for luxury brand Infiniti’s latest line of mid-size models. This twin-turbocharged petrol engine is available in 300 or 400 hp versions.
In 2007, mainly for Infiniti cars, the most advanced engine from the VQ series was introduced, designated as VQ37VHR. This unit replaced the VQ35HR and was developed on its basis. The block of cylinders VQ35HR has grown slightly in height, along with this, its rigidity has been increased.
The 2.0-liter Nissan SR20DE engine (or SR20 for short) was produced at the company’s factories from 1989 to 2002 and was installed on many popular concern models, such as Almera, Primera or Silvia. The same power unit, but in the version with single injection, was assembled under a different index SR20Di.
