Infiniti's "G" sedan can be traced back to the Skyline, introduced by Japan's Prince Motor Company in 1957. The Prince Skyline was a luxury car whose 1.5L, 60HP engine could get it to speeds up to 140kph (87 mph).Nissan and its luxury division, Infiniti. Both the car itself and its engines kept growing over the years, its engine now a huge 3.7L V6 with 328 HP.
The reason it's called the Infiniti G37 is that you can only buy it with the 3.7L V6 engine. In Japan it is equivalent to the Nissan Skyline 370GT; the cost of the "S" trim is ¥ 4,095,500 (US$ 44,200). In comparison, the Skyline 250GT, with the 2.5L V6 engine, has a price tag ¥ 3,759,000 (US$ 40,500): one of those examples where the more frugal version of a model is also less expensive in the puchase.
Under the Japanese JC08 test schedule, the 370GT fuel efficiency specification is 9.4km/L (22 mpg), while for the 250GT it is 11.4 km/L (27 mpg). Six-cylinder engines are just thirsty. The 328HP in the G37 can probably get you over 120mph, pretty much over the top, unless you live in Minnesota and/or don't mind coughing up for the speeding tickets. I mean, back in 1957 the Skyline reached 87mph on a 60 HP engine: who needs five times that much?
As for acceleration, a 2.2L diesel engine can generate torque equal to that of the G37, but at much (30%) higher fuel efficiency. So if Nissan decided to install a nice small diesel engine in the Skyline / G37 it would serve that car well enough, but at a much reduced carbon footprint.
I've always been puzzled about the engineering advantage of putting an engine in the front of a car that has rear-wheel drive. As a driver, I don't think rear-wheel drive serves anyone living in a climate that sees snowfall regularly.
