I'm surprised it hasn't happened in the past. Toyota engines have been more advanced and sophisticated than the Domestic engines.

Oh but it did. in 1995, the 1MZ claimed a 10 Best award from Wards.

I bet this one will have good chance to be added to the list. Beautiful torque curve across entire RPM range :clap:

Yep, and Toyota/Lexus's 1UZ was on Ward's list of the 10 Best Engines of the 20th Century :clap:

Since this thread is back, the 2GR-FSE has won the award for its second consecutive year. I'm sure the 2UR-GSE and 3UR-FE will find their places on it soon. The vehicles have to be at a base price less than $55k. That automatically rules out the 1UR-FSE until it reaches the GS460.

Agreed. Also because the 3UR-FE is a relatively inexpensive engine, I am confident it will make the list.

Wonder when Toyota will put out a 4.7L v8 replacement with dual VVT-i.

The current 4.7L in Tundra gets worse gas mileage than the 5.7L. The power gap between the 4.7L and the 5.7L is just too big.

Hopefully Toyota will update the 2UZ to atleast an even 300 hp.

And is it confirmed the IS-F's engine is a G head?

Toyota did say that they were going to completely overhaul their engine/transmission lineups by 2010, so a replacement/update should be out between now and then.

Not officially confirmed by Toyota, but a member of ClubLexus who has close ties with Toyota managed to get the engine code.

Just to add, Toyota inferred a G head in the presentation of the IS-F. Take a look:

Toyota said:
The result is a performance tuned 5.0-liter V8 engine, topped with specially engineered heads fed by a two-stage intake system, that produces 400-plus horsepower and more than 350 ft.-lbs. of torque. The all-new IS-F is equipped with engine-oil and transmission-fluid coolers for high-speed performance and a cylinder head-scavenging oil pump for high g-force driving.
Anytime Toyota refers to "special" head design, it's something other than the usual F head. Most likely, Yamaha helped develop these heads.

Most of Toyota's powertrains will be xR (GR, UR, TR, ZR, etc) engines, and xA (AA80E - LS460 or RA62) or xB (AB60E/F - Tundra) transmissions.

What's really interesting is that Toyota mentioned years ago at a presentation that for future powertrains, they would mostly shy away from forced induction, and focus on high performance, fuel efficient naturally aspirated engines. At the time, their move away from G heads made perfect sense.

It will be interesting to see how efficient the new G heads are.

I wouldn't mind the new Tundra if it weren't over priced.

The cheapest V6 model sells for like $22,000. No thanks. I can get a Titan with alloy wheels and a 5.6 V8 for that much money (after $3,500 rebates).

Once Toyota prices their Tundra in the same bracket as Nissan and the rest of the domestic, the new Tundra would sell like hot cakes.

Does anyone know if this engine is in any of Toyota's lineup of cars or is it only relegated to the Lexus autos?
