Infiniti will turn to turbocharged 4- and 6-cylinder engines, hybrids, full electrics

"And another one gone, and another one gone / Another one bites the dust"
Well, it looks as though the recently approved CAFE standards that aim to increase automobile fuel economy to 54.5mpg by 2025 have claimed another victim. Infiniti currently has V8 engine options available in its M luxury sedan, FX crossover, and QX sport utility vehicles, but that likely won't be the case in future iterations of those vehicles.
According to a report by AutoGuide, increasingly stringent fuel economy and emissions regulations mean that V8 engines are no longer on the table for Infiniti vehicles. V8 engines have traditionally been available in luxury vehicles as a symbol of prestige and power, but Infiniti will look to new ways to bring powerful engines to its lineup while still keeping fuel economy in check.
“I don’t think any car that is on Infiniti drawing boards from here onwards we should expect a V8 to be included in that plan,” Johan de Nysschen, Infiniti's global president.
Infiniti's 5.0-liter V8 produces 385hp, its 5.5-liter V8 produces 420hp, and its 5.6-liter V8 (truck-based) produces 400hp.

Infiniti to say good-bye to V8 engines
There are numerous directions that Infiniti can take with the absence of a V8 engine. Automakers like Ford already have twin-turbocharged V6 engines that develop 365hp while still delivering respectable fuel economy. Even Hyundai is rumored to be getting in on the action with a twin-turbocharged 3.3-liter V6 which generates 395hp.
For entry-level and mid-range models will also see a shift in available engines as well. Infiniti's current workhorse engine is the 3.7-liter “VQ” V6, but Nissan is also working on a turbocharged four-cylinder engine to deliver comparable power and vastly improved fuel economy.
Other options for Infiniti include fully electric vehicles (like the LE Concept) and additional hybrid models (we’re hoping that Infiniti delivers a production version of the Emerg-E).
Infiniti isn't the only luxury maker to drop a V8 engine from its lineup. When Lexus redesigned its mid-range GS sedan, it dropped the 4.6-liter V8 engine option and instead launched the vehicle with a 3.5-liter V6 and a 3.5-liter V6/performance hybrid model for those that want the power of a V8.

Actually, a clarification. I did a bit of research and UK road tax is based on the size of the engine, and the amount of C02 released per km.

I thought it was based on MPG, but I was wrong. I agree with you about the problems in monitoring MPG (seeing how variable it can be in relation to driving habits).

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.

Thats not true at all. It can vary depending on the octane level, impurities, engine design, age of catalytic converter, etc. In controlled lab conditions you might be right, but out on the road there would be many variables that affect the final figure.

Charge the tax based on how much gas is consumed.

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.
Cars in the UK already have to pass an annual roadworthiness test known as an MOT - this system could easily be incorporated into that without a massive increase in bureaucracy.

Such a system would also encourage greater use of public transport, car pooling, use of bikes and maybe even things like teleconferencing and flexible working hours.

Again, this is completely idiotic, and seems to me to suggest a tendency to try to over-legislate everything. You want to tax not only miles driven but fuel efficiency? Don't rate vehicles on efficiency (open to corruption) and force people to give odometer readings (just another small hassle among many others), simply tax each gallon of fuel and be done with it. People that drive more will pay more. People with less efficient vehicles that drive the same number of miles will pay more. People with less efficient vehicles that drive more will pay through the nose. It's elegant in its simplicity, and it's fair, something Big Govt's don't like (less to enforce means fewer govt jobs).
