Spotted leaving a Mercedes-Benz test facility the cars also sounded distinctly like diesels. Infiniti and Mercedes have previously announced they will share engine technology and that Infiniti will get Mercedes diesel engines. More recently Infiniti filed for a trademark on the G22d name – in addition to the G35h and G30t signifying the model line will add both a hybrid and a turbocharged 3.0-liter.
The test mules seen here, while closely resembling the current G models, do feature a slightly wider track, as well as added air intakes on the front bumper – to help feed air to the intercoolers for both the diesel and turbo gasoline engines.
