Super-Lightweight Toyota 86 TRD Griffon Concept Flies to Goodwood Festival

[TRD-X]

@Anaxilus the Innovate supercharger reuses the stock CAI and the TRD/USA CAI exits to the intake in a different place look.

[Anaxilus]

Yes, I know. Did you read where I said 'mod'? If I mod it to work w/ the Innovate is it still useless or a waste of money compared to the stock intake? I'm assuming you haven't tried it, so we don't know.

... but this is accurate. Another reason for the rear wing is not just for downforce generation alone, but also to merge airflow coming off the top of the car with what is coming from the diffuser.

I'm surprised no one has mentioned the diffuser and the (unseen) underbody work, because if TRD did indeed test this in a wind tunnel, those two pieces work together as one functional unit for a right balance of downforce/drag.

Given the HP limitations of the car, one would assume that the AoA of the wing and the adjustable height factors into this.

With this year's edition of the Goodwood Festival of Speed (FoS) in England just around the corner (July 11-14), automakers are getting ready to share their four-wheel goods, some of which are new, some of which are old.
Looking to add a playful note in its presentation, Toyota released a picture of a covered car on its Facebook page with the following message:

"Festival of Speed this week. Can you guess what it is...? Full reveal later today."

We will be really interested if it is indeed something new, but we have a hunch (and some visual proof) that the car hiding under the white wraps is none other than the lightweight Toyota 86 TRD Griffon Concept, which has not only been confirmed for FoS, but has already been shown to the public at the 2013 Tokyo Motor Show in January.

What do you think?

Update: Toyota confirmed our suspicions that the "surprise" debut for the Goodood Festival of Speed isn't really a surprise at all, as it's a slightly updated (see wheels, fender vents) iteration of the Tokyo Motor Show 86 Griffon Concept, a study for a 500 pound (226.7 kg) lighter, track-day version of the Japanese firm's coupe. And for those of you wondering, the last picture in the renewed gallery below is of the heli-cam used during the photo shoot.

What are the new wheels?

[cyde01]

new wheels look like tws t-66f!!!!

aside from that it has new fender vents, the canards look definitely bigger, is the rear wing even bigger than it was before also???

[OnkelC]

I am so tempted by the Gauges...

[Touge_ninja]

Take my money!!!! Seriously take it!!!!!!!

[zephyr69]

I'm going to order those rims and gauges! I just checked TWS and those rims are competition spec and supposedly lightest in the world (4.4KG). Used by many Super GT, 24 Hour Endurance, Formula 3 Cars.

One year on from launching the Toyota GT86 at the Festival of Speed, Toyota returns to Goodwood to give crowds first sight of a pure-bred racing version of its multi-award winning sports coupe. The TRD Griffon Project, created by Toyota Racing Developments, will be making its first UK appearance at the popular event, following its unveiling at this year's Tokyo Auto Salon – Japan's premier customisation show.

The TRD Griffon Project is a development of the GT86 designed specifically for track driving. Modifications have been made throughout the car to reduce weight, strengthen the chassis and introduce racing-specification TRD accessories.

The overall body shape follows the same low, muscular lines of the original coupe, but with the bonnet, roof, doors, boot lid and rear wings made from lightweight carbon fibre. Further weight is saved by using carbonfibre reinforced plastic – CFRP – for the bumpers, wider front wings and rear diffuser. All the windows are made from polycarbonate material instead of glass.

The cabin is fitted with a TRD driver's bucket seat, gear shift knob, ignition button and oil pressure and water temperature gauges. There is also a Momo steering wheel and Takata seatbelts.

Many of the car's components have been strengthened or upgraded: the standard Torsen limited-slip differential has been replaced by a TRD mechanical LSD and the suspension has been significantly reinforced. Coil over suspension kit is used and the final gear ratio has been shortened to 4.8:1.

Further performance-related changes include an oil cooler for the engine and a TRD mono block brake calliper kit with racing spec brake pads. The TRD Griffon Project runs on TWS 18-inch wheels with Yokohama Advan tyres. The 2.0-litre, normally aspirated "boxer" engine that characterises the GT86 retains the same specification as in the road-going car.

UK customers can also enjoy the benefit of authentic TRD parts on their road-going GT86. The GT86 TRD is a limited edition version of the standard car that gains a series of genuine styling and performance accessories, including 18-inch alloys, front and side skirts, a rear spoiler, fast-response quad-exhaust and TRD-branded detailing on the filler cap, gear knob and radiator cap.

The amount of horsepower on a motor has absolutely nothing to do with downforce stop trolling.

No offense to people who use TRD USA stuff. But they really suck.

Doesn't add much horsepower here anyway

Not only did they test in the tunnel, if you look at the test videos you can see them slathering on the aerodynamic test paint on the car to see the flow of air like in Formula 1. They really are trying to make the best with what they have not adding more than 9-13 hp from a legal racing exhaust and making the car using weight, gearing and aerodynamics to its advantage, its pretty mind boggling.

The Griffon, which uses the same 2.0-litre boxer engine as the standard GT86, is reported to develop more than 300bhp, compared to the standard car’s 197bhp.
