yes we don't see what "entrances/ducts" are behind the disk brakes... but nevertheless if they have an Axial kind of generator inside each wheel hub, this will also need cooling and is also a potent breaker (eddy currents, magnetic drag)...so the "friction part" can be alleviated( just to remember once F1 had magnetic brakes, i.e., no friction).

Toyota could do with some good PR from the TS040 right about now: http://news.yahoo.com/toyota-recalls...060803198.html

So could GM! At least no fatal injuries are reported! This seems like a quality control issue from 'old Toyota'

Anyway, thought sharing this picture would be nice. Its a great look at the high downforce package and aero wheels

Nice, thanks for that. Another one for the wallpaper collection

Thought I'd share this from when I visited Toyota Kaikan, one of 2000 photos! Not really TS040 related but I can't be bothered digging out the old thread


Edit: Some nice work by signor Pannullo

According to Japanese Autosport magazine,
Toyota had developed small displacement DI turbo engine and large displacement NA engine for 2014 regulations and carried out the comparative test.
Since there was a demerit in combustion and weight in the race, the direct-injection was not adopted.

Thats something I thought about being the weight disadvantage of direct injection.

I trust that Toyota is simply taking the time to air out some dirty laundry because the GM scandal is so much bigger than anything I've ever heard of.

GasperG has a lot of promise if they can keep it on the circuit!
Toyota's vision of future efficient engines is still non turbo, non DI:
http://www.greencarcongress.com/2014...40410-tmc.html

Therefore they are making a great point with the "simple" (not really) engine in TS040.

That's a really neat article. DI is expensive.

Incorrect for production engines. On the new Lexus NX model debuting later this year, Toyota will be introducing a new engine, a 4 cylinder I4 that uses Toyota's D4-S DI system and it will also have a turbo system.

Additionally, Toyota has already started applying their DI system to "mass" affordable engines. The Toyota 86/FR-S/Subaru BR-Z uses Toyota's D4-S DI system on that boxer engine, and that is quite an affordable car.

Those engines you linked above are very small and low-cost engines. It's great to see however VVT-iE now being offered on affordable engines. Wait until Toyota shows off the rest of their new engine lineup. Many of the engines above 1.3L are likely to have turbo, DI, or both.

Toyota has also done lots of turbo research overall the last 7-8 years, which has culminated with the fact that some of their brand new engines will have turbo systems, for the first time in a long time for Toyota.

Let's wait and see what Toyota brings to production. The ultimate combination I eagerly await is an engine that combines their D4-S, Valvematic, and VVT-iE systems together. Also await the debut of Dual VVT-iE. With such an engine, you'd have the advantages of both port and direct injection, infinitely variable electronic valve lift, and infinitely variable electronic valve timing on intake and exhaust sides.

As for the TS040, within the regulations and limitations of the WEC, Toyota simply decided that for this specific situation, there are more benefits to run the engine without DI as opposed to with it.

I think Toyota mentioned they had one or two more post-prologue tests.

Toyota this season has purposely undertaken a quiet and secretive test program. They did almost 20,000 km of pre-season testing before the start of the prologue. They most certainly have not been "resting".

Check their driver's twitter feeds. They let slip little info here and there. Pretty sure Alex Wurz said something about it a couple days back.

Those examples are Lexus and sports cars only, I do remember someone from Toyota said that Turbo is there only for greater power not efficiency. Of course we will see Turbo engine but this is just because the customers like it (torque).

I do wonder why so little Toyota cars (300h, Gt86) use D4-S system, where competition from VW, Kia, Hyundai, Ford ... are all using DI in their cheaper models. Maybe DI is good when it comes to different real world power needs, but not beneficial when it comes to WOT efficiency.

Competing with hybrid and on limited gas, I think we can not compare TS040 to sporty models from Toyota, but from the ones that have the highest engine efficiency at WOT. I do wonder what does are? Prius engine

Metaphorically or literally?

On a slightly more serious note, I think/hope Toyota are past the trial and error stage of their effort with a pretty solid outcome at Le Mans last season. Hopefully the experience and knowledge they've gained should mean they won't face the same hurdles with the TS040 that they did with the TS030
