quote: On the other hand, large displacement 4 cylinders can be efficient but I agree they aren't very smooth.
quote: I'm pretty sure this isn't true any more. It used to be that way.
quote: In my opinion, I think a 1.5-2.0L turbocharged inline 6 engine would be sweetness as it would provide the smoothness and balance of a V8 with the fuel economy of a 4 cylinder engine.
quote: Looking at the big picture here, we have 3.5l V6s that put out the same or even more than their old larger V8s did. Who needs a V8?
quote: BMW is putting out some insanely impressive numbers. 240HP 23/27/34
quote: I used to think there is no replacement for displacement. But a super light car, that handles well, with a responsive throttle, is WAY better than a heavy V8 powered lead sled. I also could really give a fig about "smoothness" if I need to pay double gas price for that benefit. I'll stick to my "underpowered" subarus thanks.
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.
quote: Do we really need a Toyota Camry that will ditch a lot of sports cars from ten years ago?
quote: But it would probably be smart to turn the efficiency benefits into smaller engines.
quote: typical under educated naive American reply.. my 2001 jetta tdi alreday returns 55 mpg.. just have to laugh at your stupid gas guzzling asses..
quote: Car makers have plenty of research and development. The 54.5 MPG may seem far, but soon they will reach it.
quote: The UK implement an annual road tax based on how efficient the car is, and on how much pollution it generates. This doesn't cause highly inefficient vehicles to go away - they're still there if people want them, but for many it makes more sense to get an efficient vehicle due to the saving they make on both road tax and fuel.
quote: The UK implement an annual road tax based on how efficient the car is, and on how much pollution it generates.
quote: In the end, a gallon of gasoline will release the same amount of pollution whether it carries you 1 mile or 100 miles and regardless of whether it burned by a motorcycle or a truck.
quote: Err, .. wait. In the end, a gallon of gasoline will release the same amount of pollution whether it carries you 1 mile or 100 miles and regardless of whether it burned by a motorcycle or a truck.
quote: Charge the tax based on how much gas is consumed.
quote: Some have suggested modifying the road tax system to incorporate a tax based on miles travelled per year, based on odometer readings. Higher odometer reading = more tax.
quote: It's all horribly conceived and a huge mess.
quote: EVs and hybrids are the way to the future.
quote: by soloburrito on September 4, 2012 at 2:56If you think the EPA is full of hot air, look at some pictures of Beijing during their killer smog days. I'd rather have the EPA around than not.
quote: You do realize CAFE has no impact on smog forming pollutants, right?
quote: As an auto enthusiast myself I feel a good deal of the arguments around CAFE. But as person living at this time, there is a bigger picture that I cannot ignore. Just like a little kid must learn you cannot have pizza at every meal, we as a society must adjust to a reality that we must adjust our transportation needs and wants to achieve a better future.
