quote: I was thinking of the V6's, which I might add are based of a 30+ year old DOHC design (obviously having since gone all aluminum with MPFI, but still not GDI) but the casting and cam runners are identical to those from the 80's originally developed out of the Datsun era.
quote: I don't think CAFE is claiming any victims here
quote: I can count at least two cylinders that won't make the bill of materials and weight list when shipping a V6/I6 over a V8.
quote: As far as the VG/VX/VQ engine relation arguement is concerned, yes, they share quite a lot. Nissan hasn't retooled their equipment for decades, which is why they continue to manufacture the same displacement across the board in the North American market.
quote: Infiniti sales have been lagging for years, and they have among the lowest fuel economy of any V8 luxury-class (only Jaguar/Land Rover are worse in the WT25 sales) and consumers have clearly spoken. The best selling luxury cars are typically I4, V6 or I6, those being Audi A3/A4 2.0T, Mercedes C-class (the 3.5 M112 is their best selling engine) and obvious BMW's fleet of I6's.
quote: Infiniti has taken the correct approach in deciding NOT to develope a whole new V8 engine for mass production and instead focus on what most other manufactures are doing, that is, developing small, powerful, economical and fuel efficient turbo-charged engines.
quote: Exhaust is free power, and if Chrysler hadn't completely destroyed the reputation of turbocharging in the 80's and early 90's by poorly implementing them (usually without liquid cooling, often causing oil to overheat blowing headgaskets or various seals in the turbo housing failing, and no implementation of a 'turbo timer' or cool-down system which is required when not running liquid cooling
quote: Basically Infiniti is going to save costs using less materials and shipping less weight to the United States, and consumers are going to get better fuel economy with similar, if not better, performance.
