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.

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.


Your reasoning is completely flawed. You mention that Nissan is saving money and weight by going with a V6/I6, but Nissan's V6s and I6s are very stout. The Nissan 2.0 liter I6 from the Z31 weighs more than the 7 liter V8 that Chevy makes. The GTR's 3.8 liter V6 weighs almost 150 lbs more than the 7 liter LS7. How is Nissan saving money on shipping less weight when the engine they are shipping is actually heavier? Instead of shipping a lightweight V8 they're shipping a very heavy V6.

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.


Wrong. Dead wrong. The VG and VQ engines do NOT share quite a lot. In fact they're entirely different. I'd like you to find me a single internal engine part that can be swapped from a VQ engine to a VG engine.

The block is completely different and the engine mount location is different.
The crankshaft is different
The connecting rods are different
The pistons are different
The oil pump is different
The heads are different
The valves are different
The camshafts are different
The lifters are different
The intake manifold is different
The exhaust manifold is different
