Report: Infiniti Planning 530 HP, Twin-Turbo V-6 for Next-Gen G37 IPL

The current-generation Infiniti G sedan, coupe, and convertible is getting long in the tooth, especially when stacked up against its newer, more advanced competition. But fear not Infiniti fans: a new G is right around the corner, and the next IPL version will aim squarely at the BMW M3 and Mercedes-Benz C63 AMG packing 530 hp.
According to the insider that Motor Trend spoke with in Japan, the third-generation Infiniti G range has already had both its design and powertrains finalized as of last year. The car is slated to go on sale in the U.S. and Japan by the end of next summer, and then roll out in 70 other countries worldwide.
The design will draw heavily on the Etherea concept from last year’s Geneva Motor Show, especially the front clip, according to MT. The G sedan will also move away from a traditional three-box design toward a more sinewy four-door coupe-like profile – aided by a longer wheelbase – although it will retain roughly the same interior and exterior dimensions as the current car. Word is that Infiniti is trying to go for a more luxurious and more muscular look this time around.
Underpinning the new G will be the same platform as the next-generation Mercedes-Benz C-Class, which is due around the same time. The only other fruit of the Renault-Nissan and Daimler deal in regards to the G will be the sharing of a 2.1-liter diesel four-cylinder, which is currently used in the European-market C220 CDI; in that car, the engine is rated for 168 hp and 295 lb-ft of torque. Infiniti is planning to use a new catalyzer that will help to boost the torque output to around 360 lb-ft; however, the diesel G is not bound for U.S. or Japanese shores because of low demand for oil-burning cars. What we will get, instead, is a hybrid version. The G hybrid will use a variation of the powerplant found in the M35h hybrid, but with a smaller battery pack. Expect the main engine to be a direct-injected revision of the current car’s sweet-sounding and powerful 3.7-liter V-6.
For enthusiasts, Infiniti is looking to push the prestige of its IPL (Infiniti Performance Line) into the same rarified air of BMW’ M, Mercedes’ AMG, and Audi’s RS brands. “We have an all-new engine in the pipeline that will only be built in Japan, as it requires specialized production methods only available [there]. It is a totally new 3.7-liter direct injection, twin-turbocharged V-6…[that] will generate upwards of 530 hp.”
Perhaps most interestingly, the next-gen G will no longer be built only in Japan. We’ve already reported that Nissan will build Mercedes-Benz engines at its Smyrna, TN plantMT reports that some V-6-equipped G models will also be built there. The rest of the V-6 cars and the hybrid will be built at the automaker’s Iwaki plant in Japan.
Also in the pipeline for Nissan’s premium brand is the production version of the LE Concept from this month’s New York show (to be built in Japan and Tennessee) and the production version of the Etherea Concept. The Etherea will also share its platform with Mercedes – here using the three-pointed star’s MFA front-wheel drive architecture found under the new A-Class. Expect to see a supercharged 2.5-liter four-cylinder hybrid powering the compact hatchback.
