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.

anyone complaining about not having a V8 needs to try driving a light sporty Japanese 4cyl car for a few weeks. 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.

And spend a day with me at the track with a 1000hp V8.

Yeah, it's a few hundred pounds more than your Subaru, but it's made up with a hellava lot more smiles.

I'm raising the bullsh!t flag bro.

2012 Subaru WRX STi Sedan
Price As Tested $ 34,845

Horsepower 305 @ 6000 rpm
Torque (lb-ft) 290 @ 4000 rpm
Curb Weight 3384 lbs.
Pounds Per Horsepower 11.1

EPA Fuel Economy - miles per gallon
city / highway 17 / 23
0 to 60 mph 5.3 sec.

2012 Ford Mustang Coupe
(5.0L V8 6-speed Manual)
Horsepower (hp @ rpm)420 @ 6,500
Torque (lb-ft @ rpm)390 @ 4,250
Curb weight(lbs.) 3,620
Pounds Per Horsepower 8.6

EPA fuel economy (mpg)
16 city/24 highway
0-60 mph (sec.)4.8

I'm not knocking the WRX, I think they're awesome cars. I had a 94 Japanese spec than hung on just off the door of my 06 mustang all the way up to about 85 before the mustang started to really pull away. Both were stock at the time. Unfortuantely I moved to Virginia, so i left it in England. My friend had a 2004(US spec)and he'd consistenly beat me to 60, and I'd always get him at the 1/4 though. Those cars are every much the beast people say they are. Fantastic machines, but lets keep a few thigns in check.

Now comparing the 2012 models, the subaru loses on HP/Weight ratio, it loses on "responsiveness" Sorry , but the butt dyno doesnt count. You can google the specs and look for yourself. Number dont lie. Reclaimer already called you out about fuel economy, but listed above is the EPA's

Subaru isn't exactly cutting edge with all the new efficiency technologies. A better comparison is to look what kind of HP BMW is getting out of their new designs for how much gas they use. BMW is putting out some insanely impressive numbers.
240HP 23/27/34

As they usually do but, that has nothing to do with what I was replying to...

Yeah that's fair to Subaru. Notice how much those cutting edge technologies add to the cost of those BMW's per chance?

The new all aluminum Boxer engine is pretty efficient. The drive-line losses due to the AWD system is where you lose a lot of fuel economy, not from the engine itself.

Compare apples to apples here.

Bingo! BWM's AWD sedan has the EXACT same mileage ratings as the WRX.

BMW is putting out some insanely impressive numbers. 240HP 23/27/34

Only when you cherry pick :)

Hello? Gonna pretend you didn't see this huh. Where's your vaunted BMW now?

Let's compare the Subaru WRX to a "heavy V8 powered lead sled" Corvette.

WRX Curb Weight: 3073
Corvette Curb Weight: 3199

WRX Fuel Economy: 17/19/23 mpg
Corvette Fuel Economy:16/19/26 mpg

The "lead sled" weighs only 4% more, has 67% more power, and as a final insult to injury gets the same/better gas mileage.

While I would never pick a WRX over a ' own pocketbook notwithstanding...I thought I'd point out that there's also considerably different levels of investment going on there.

A 2012 WRX STi is about $36k.

Corvettes start at $50k for the barebones version...and run up to $111k for the ZR1.

A closer comparison might be the Camaro. Which can be had in a reasonable trim for ~$36k. Weight about 3750, 426hp, 16/24mpg.

So, ~22% more weight, but ~40% more power. And better gas mileage (on the highway, anyway).

In my book, decision still goes to the Camaro.

I'd never pick a chevy over any Ford or Subaru. I miss my Subaru, it made an awesome winter car. Mustang, not so great during the winter.

Agreed, the vette is an unfair compare. I posted the mustang vs Subaru wrx comparo above, since they're similarly priced and weights are pretty close.
