Please help me understand why proven reliable naturally aspirated legendary V8 cheaper to produce engine was discontinued and replaced with not so great v6 twin turbo setup with double the price which consumes same amount of fuel per gallon by just a mile or two increase?

Emissions and fuel economy compliance. It does not matter because the inevitable is coming sooner than we thought.

• V8 disappearing
• Sedans stop production
• Manual transmissions dropped
• Diesel engines disappear (see Volvo)
• Finally, all ICE will be phased out and for any remaining ICE vehicles on the road gas will be scarce and expensive.

That's not a straight answer. There must be a concrete explanation to it. Forced by governments? Pushed by laws?
Manuals are disappearing but they do have a definite answer, they say the sales of manual are significantly lower than automatics because todays generation does not know how to connect to a WiFi without scanning barcode.
Diesels disappearing because people don't like the sound it makes and hard to maintain emissions system that constantly breaks down.
I am not aware of the data to speak accurately but these statements do have some point to backup the manufacturer's decision but the change with LC and LX is just not understandable for me.

Don't get me wrong. I am a fan of diesel cars and manual transmissions. I am a man of culture. Just speaking facts so nobody is offended, in this era where addressing wrongly can upset millions at once.

EPA mandated new Corporate Average Fuel Economy rules. To achieve 49 miles per gallon by 2026, automakers in USA are abandoning the V8 altogether.

Consider the possibility that Lexus fell short of their goals for the V6 but due to sunk costs has no choice but to use the engine.

In that case why not just don't have v8 option for america and have engine options for rest of the world. LX and LC is sold more in middle east and russia compared to US sales reports.

This is just the natural evolution of ICE engines. They can get the same horsepower and torque with V6 engines (and V4s) and turbos with better mileage so why the V8 at this point? They are not trying to compete with the Germans on performance. So they are phasing them out.

And what's wrong with the V35?

I believe Lexus already had this engine developed/used in another car before Toyota started using it in the TNGA, with some tweaks. It meets the specifications needed for the 300/600/Tundra. If the Tundra competes with the F150 its fine.

If you are in the North American market you would be familiar with the Turbo V6 Ford trucks and vans. They do the job fine and meet mpg and epa standards. In real life they get similar mpg to a V8 NA. You get some benefits of being able to tune, less fuel consumption at idle, and more power at elevation. You can also ‘get into the boost’ if you know how to work it. Ford gets to use less parts and have a smaller package to deal with.

I have had the 3.5 and 2.7 Turbo F150. The 2.7 was a little bit more peppy and sounded way better, it sounded good. Have had lots of different vehicles and the 2.7 sounded and performed really well for a utilitarian basic truck.




I wouldn’t worry about it. Toyota has them so muffled you only hear the mechanical sounds. I also had a 5.7 V8 Tundra. I have an lx600 on order
