Toyota building new twin-turbo V6, to appear in GS, LS
#61
Pole Position
Nobody can defy physics. More power will always equal to more fuel being used. Hybrids changes that equation somewhat. The only real benefit is the ability to use smaller engines that requires less fuel while stuck in traffic or idling. If you need to go in a hurry, it will burn fuel. My GS350 does not feel underpowered, just not as fast as the competition. Honestly, with the speed limits at 55 in NY and 65 in most of the US...the heck I need 400+ hp for?

Funny how your comment aligns perfectly with a very recent article I had read which may have Toyota Motorsports GmbH confirming the development of a turbocharged hybrid engine (perhaps this is the extreme-performance version of the V6TT): http://www.motor1.com/news/65783/toy...ine-for-supra/
Nissan's VR38 engine block has proven to be very strong with its cast aluminum alloy design. Toyota has previously stated that their mission with the new Supra would not be to chase the GTR (in raw performance numbers or AWD) but I hope the extra care going in to developing this 3.0L V6 twin turbo + hybrid means they are also taking toughness, durability and ultimate potential seriously in their own right. The Lexus models that also get variants of it will only greatly benefit as they did in the 1990's (in Japan anyway).

Excellent post
Definitely a reason the 2.0T took so long to come to frutiion. Lexus [almost always] dots all the i's and crosses all the t's before releasing them to consumers. The upcoming six and eight cylinder engines should be a great real world balance of performance, efficiency, and refinement.

We should also realise that the 2.0T offers air-to-liquid intercooling, when its (current) power output only suggests the need for air-to-air intercooling. That is likely growth that was built into this engine.

The reason turbos are being pushed is because a turbo is a well-known technology that is relatively easy (read cheap) to implement, much easier (and much cheaper) than Toyota's hybrid drive technology, and (backed up by outrageous government fuel economy claims) able to kill 2 birds: offer extra power AND fuel economy.

again if turbo was this superior, why wasnt every car turboed long ago they arent a new invention. The primary advantage of turbos is volumetric efficiency and power density, not fuel efficiency. It can be fuel efficient if you drive it like Miss Daisy and stay off boost. Otherwise it consumes a lot of fuel while on boost. Lets not even get started on reliability. A turbo engine will always be less reliable than a comparable NA. The driving experience is very different as well. You think Ferrari Porsche would go to turbo (now every 911 is turbo) absent these lowsy govt regs? They are forced too despite what they truly want to build. Turbos are not the silver bullet, they have issues of their own. Turbos are good at gaming the govt test bench during mileage testing. Real world mpg is often a disappointment. This turbo trend is nothing more than govt intervention and car makers having to build cars they and the consumers didnt ask for.

The reason that we have not had turbochargers in great numbers to now is because we have not needed them. A turbo is still something you add to an engine (but something relatively easy to add, especially compared to a hybrid drivetrain) so it is more difficult -- and more expensive -- than a naturally-aspirated engine.

This is good thread to bump as the rumors proved true, although the displacement was wrong, unless of course Toyota is also developing a 3.0 Liter TT.
Most of the early rumors suggested this engine would also find its way into the GS, so unless Toyota was being disingenuous about saying the 3.5 L was developed specifically for the LS, it could very well find its way into the GS.
Will Toyota detune this engine for the GS? I think that would be a mistake, but at the same time it would diminish the value of the LS, again assuming the 3.5 L is the only V6 TT Toyota is developing.
What benefit would it have developing a 3 liter TT now that it has the 3.5? Just seems too similar so the next GS may very well have the same engine. Even if detuned, I'm sure nothing more than a laptop could unlock the LS level lol.

A 3.0 V6 TT will be both more economical and smoother than a 3.5 V6 TT, but the latter will have more power and torque.
The 3.0 V6 TT can be lighter if it is made from its own block.
However, if they did make a 3.0 V6 TT for the GS, then commonsense would say that they would make a 2.5 V6 TT for the IS; this would be great if it were true.
Having three different V6 capacities would also prevent devaluing the more expensive models.
Many decades ago, Toyota had their in-line and V6's in many different capacities like 2.0, 2.5, 3.0, 3.5 and even 4.0 for some of their commercial vehicles.
However, right now, I just don't see TMC making too many different variations in capacities.
I haven't even heard of TMC move into 1.5 and 2.5L four cylinder turbos like the Honda Civic and Mazda CX-9.
