Unraced Toyota TF110 with “extreme” diffuser driven by Kazuki Nakajima

The car Toyota would have raced in F1 this year has been driven by Kazuki Nakajima in Cologne.

The TF110 has been revealed and inspected by Racecar Engineering. and looks outwardly similar to the BMW Sauber C29 with a high, long nose.

Toyota’s 11th hour exit from Formula 1 at the end of 2009 means this car will never compete in F1.

Two examples of the TF110 were built despite the team’s decision at the end of last year not to contest the 2010 championship.

According to the magazine the design features “one of the most extreme diffusers seen yet” and a ride height adjustment system.

Who knows how competitive the TF110 would have been. It’s doubtful that, even if another team acquired the intellectual property rights to use the car in 2011, it could be suitably modified to be competitive following further changes to F1’s technical regulations.

The manner in which Toyota exited the sport within days of the 2009 season ending is a reminder of how close the former Honda team came to disappearing 12 months earlier.

As Ross Brawn explained afterwards, the company’s management hadn’t given any thought to passing the team on to another owner and had to be persuaded to accept Brawn’s management buy-out. It seems much the same happened at Toyota.

While BMW also, though with some difficulty, passed ownership of their team back to Peter Sauber, Toyota cut and run and there was no going back. Attempts by Zoran Stefanovich to use the cars to obtain an entry failed.

Recently former Toyota boss Tadashi Yamashina explained how the onset of the credit crunch hastened the team’s departure from Formula 1.

It’s a pity to see an F1 car, built at considerable expense, sat idle when it could be competing. Hopefully we’ll only have to wait until next year to see F1 get back to 26-car grids.

  1. That thing does look pretty nice, especially in naked carbon fiber. A pretty radical nosecone too, especially compared to toyota’s previous designs which were all pretty conventional.

    1. i dont agree toyota in 2005 07 08 09 showed a lot of new designs and new concept like for instances the 09 rear wing which was very close to the ground as drivers complained toyota engine was lacking power and with wear it only got worse

  2. So it should have been another Brawn story! But i guess we’ll never know!

    1. Agreed, Crying Shame, Really! Would love to have known what it could do..

  3. It could have been so much more than a show car….

    What a shame.. To be honest Toyota did build some good cars. Their 2009 car wasn’t a bad car. It scored multiple podiums & a pole position.

    This could have been such a good car… I wish we could see a video..

    Are there any more pictures Keith?

    1. Could also have been totally awful.

      1. Schrödinger’s cat anybody?

          Moar liek Schrödinger’s car, m i rite?

  4. Nice design. Looks like it has an air opening similar to Ferrari’s F-Duct location. Same looks like it would have been a competitive car.

    And had Stefan GP secured this car, they would have clearly been at the front of the new teams.

    1. Those are actually engine air inlets, similar to those of Mercedes.
      Even more similar are they to those of 1989 Ferrari:

  5. Somebody stick a Mercedes logo on it quick before it’s too late!

  6. Stefan gp were going to use this car if they were allowed in. Mate they would have been quite compeitive

    Strange. What’s in it for Toyota to give a magazine access to a car that will never race?

    Also Keith aren’t Toyota going to keep developing the car throughout 2010 and try again to sell it to a customer in 2011? I heard ART would be interested

    1. Toyota don’t own the car any more Ned. They sold the cars to StefanGP…

      1. Stefan GP has no money even for paying just the steering wheel.

        I’m pretty sure the cars still belong to Toyota. Stefan GP were only going to rent them, and when it emerged they bweren’t going to be on the grid this year Toyota took them back

        1. I think Toyota severed ties with Stefan GP after more detials of the non existence of a solid base for that team came to light, and the FIA would not let them race.

          The cars were never close to being shipped anywhere let alone raced by StepanGP. I suppose Toyota is now offering some work for HRT or for one of the teams taking the 13th grid spot.

  8. So much for the theory that Lotus effectively used the TF110 as their chassis then.

    1. Pretty sure that theory was crap to begin with…

    2. Nope, they used the Force India 2009 car. Or at least FI claimed that it was their windtunnel model.

    i wanna see it up against current cars :( or at least go around a circuit.

  10. Looking at the pics, it begs to wonder why a team is not running with black carbon fiber body panels with sponser stickers in white. I’d say that would be the best looking car on track.

    1. Exactly what I thought.
      I have no clue if this car would have been competitive (probably yes; better than HRT in any case…) but this baby certainly looks absolutely AWESOME!!!!!!

  11. If I were Hispania I’d ditch the Dallara and snap this beauty up pretty damn quick !!

      21st May 2010, 21:43

      They have no money to pay for development parts (or spares for that matter) for their Dallaras, where are they going to find money to switch chassis’s (chassises?, chassii?, chassi’s, chassi-i??

      1. Plural is chassis, just the same as the singlar, :)

        1. I totally agree with you. Forger the Money, just hand the car over to HRT.. This has got to be the biggest heart break in F1, to see a car THAT good looking, and not raced..

          Forget about Dallara :)

  12. Pretty nice. Who knows how well it would have done this year? No offence, but if it was driven by Glock & Trulli, I doubt it’d have been any more competitive than Mercedes are.

    1. Glock and Trulli have gotta be better than Nakajima and Villeneuve surely!

    1. Sweet find. Found this pic too…


      Closer look at the front end.

      1. The nose is sweet. Kinda follows the same shape as the Mclaren nose. Wide and Flat.


        1. http://response.jp/imgs/zoom/264254.jpg

          Interesting shot of the lower rear wing end plate. It has shaped slots.. This is new? I have not seen any other team run this?

          1. Toyota had them last year on the TF109

            The front wing is a Gascgoyne design, similar to the Lotus front wing.

          2. Meh, looks like a cross between the Sauber and the Williams, not a magnificent double diffuser either.

            This looks like it would have been racing at the back with the other established teams, I wish HRT or someone had the funds to buy it though, Lotus?

            Ah well, sad that it wasn’t raced, definatley wouldn’t have been with the new teams but I’m not devastated.

  13. It looks like something that would take part in some sort of ‘Elitist’ racing series. I’m disappointed in Toyota for designing such a thing!

    …remember the Toyota karma….

    ..which means of course, that this car would have been a championship contender at the least. They abandoned ship just as it was coming in…(just never getting it right!)

    At least the two Japanese car giants, as far as F1 goes of late, are still joined at the hip, or is that the funny bone, probably not, as I hear no laughter coming from that corner of the world.

    Someone should ask King Adrian N. what he thinks.

    Keith which track was the car driven at? Did it use 2010 F1 tyres and if so are there any lap times?

    1. They wouldn’t have been allowed 2010 F1 tyres – remember that not being provided any tyres by Bridgestone (because of not having an entry) was what stopped Stefan testing with this car pre-season.

  16. Had only Raikkönen or Kubica choosen to drive fo Toyota this year, I think the team would be saved and that car would have challenged for the title now. Or it would’ve been too slow, we’ll never know.

    1. Not really…

      Had Toyota been a reasonably good team, it would’ve been racing this year, no matter its drivers. But it just wasn’t.

      I really don’t miss them. They were pretty much hopeless…

      1. I think the Toyota bosses told the team they wantet to quit the sport because of no sucsess, and the team replied in a desperet atempt to save the team that the car was good enough to win but that they lacked winning drivers. Toyota would probably give the team another chance, if they got proven winners like Kubica or Räikkönen, so they openly said they wanted them. As none of them were interested, Toyota didn’t want to spend any more money and the team was shut down.

        Of course, I’m only guessing.

        1. Sounds like a very reasonable hypothesis.

    2. @OEL

      agree absolutely. Also Trulli had two chances of scoring the badly needed win at Bahrain and Spa but he and team messed up. Toyota definitely lacked quality people like say Newey and Vettel combo, Brawn and Schumacher combo or just Hamilton or Alonso like drivers and they could have had much more success.

      Seeing the TF110 like that makes me very sad. What it could have been only God knows but i just think it could have been Toyota’s best car yet and very competitive.

      1. In DC’s book (I think it’s DC) he mentioned that he approached Toyota about driving for them in 2005 after he left McLaren. Apparently the management were very dismissive and believed they already had the two best drivers on the grid in Ralf and Trulli. Kinda says it all…

  17. To be honest I don’t think it would have been able to beat the RBRs but part of me is sad we don’t get to see it racing competatively, afterall it looks a cracker!

  18. The exhaust pipes looks to be at a lower position than the normal cars.looks like it’ll blow all the hot air into the tyres not the diffuser.may be it’ll heat up the tyres faster than normal

    1. Rob Gallagher
      22nd May 2010, 0:58

      No, that would just blster the tyres and damage them.

  19. The front wing is quite good i think.it has a bent slot to deviate the turbulent air from the front tyres.i think the new teams can buy some parts of the car budget permitting i guess.

  20. @rob may be they have some integrated air cooling device bcoz the pipes look to be blowing the air straight into the rear tyres

    what a shame! does anyone know if its still too late to use this car and possibly introduce it as a B-spec at some point in the season? i cant help but to think what would have happened if someone with a grid entry like virgin or lotus had snapped this baby up. instead the cars chances of being competed was ******** around by some dimwit from Serbia without even a grid entry and a website full of spelling mistakes.

    1. and a website full of spelling mistakes.

      I sure hope he isn’t talking about me…

        nah i was’nt talking about you Keith.

    2. So true and that con artist from Serbia had many fans riled up too. Frightening how easily people get manipulated.

    it’s a pity they’d have painted it in thier boring red/white color scheme

    1. The Stefan GP red looks like a big mistake, no way Ferrari would have agreed with that.

      Interesting keel below the very high and flat nose, it almost looks as if they have air inlets of some sort behind it. Shame they do not show much of the diffusor.
      And look at the position of those camera mounts.

  23. I feel sad as Keith said those cars belongs on the race tracks not in a showroom. I think that car could have been competitive they did a great job with the car on the tail end of 2009.

    “and a ride height adjustment system . . .”
    Hmmm. I wonder if that’s similar to what the Red Bulls seem to have? And is it legal?

    1. Well, it’s not like this one is going to have to pass scrutineering!

    2. It’s claimed that Ferrari has a legal system too.

  25. Remember, Jacques Villeneuve had a seat fitting for this car, and had already been in the car with the engine started up.

    Imagine if this car had been legal, fully developed and quick, Jacques could have done a Button for 2010!

    1. imagine that!! that would of been AMAAAZING!

  26. Toyota should have sold their car to USF1. That way the could have exited the sport as a whole team and reduced cost but could have remained as Engine partners.
    It would have been a win-win situation for both parties. As USF1 would get a full developed car and Toyota would get extra publicity in the highly attractive US market.

    I still don’t understand why BMW & Toyota had to exit the sport fully. They could have still got the Marketing advantages of F1 by remaining on as engine partners. Especially if they stayed on with Sauber & Williams.

    1. I think the problem with USF1 was a financial one. It was reported that the main sponsor-to-be bailed out after seeing the team had no hope of making the grid at Bahrain. If you read the current issue of F1-Racing, all the team had to show for was a half-finished nose cone.

      As for Stefan-GP, I tend to agree with Max Mosley and Luca di Montezemolo. Stefan was not never a serious candidate. They had nothing but a letter from the Serbian tourism commission saying the team had their full support. Forgive me for saying this, but these Balkan were nothing but a bunch of con-artists. Their purchase of the Toyota F1 assets were contingent on them getting entry into F1.

      I think someone should continue to talk with the Toyota F1 team (or what’s left of it). If their technical capabilities have not withered too much, then I think they are able to design a decent car for the 2011 season much like Honda did when they wrote off the 2008 season and focused on 2009.

      BMW and Toyota had to quit F1 because they were not achieving any success and both companies were laying off staff en masse. For BMW, it was a choice of laying off 2,000 employees or save that money by quitting F1. Also, BMW had pinned its hopes on its KERS and it didn’t deliver.

      1. Well actually the team was more or less standing still in the development and manufacturing. That prompted the sponsors to back out and made it go under.
        So if they would have jumped at the possibility immediately in January and snapped it up, USF1 might have had a chance.

        Toyota could have been happy to help them, as it would be good for the american market!

  27. I really hate to see people lapping up all the BS from teams about the financial uncertainty making them quit F1… Toyota is still competing in many series… The reason why some big ticket manufacturers cut and run was because of more privateers coming in, which is not a bad thing. However means to allow more teams/ privateers in were questionable at the very best. Things like forced cost cuts/ budgets, and regulations to restrict development work(for lack of a better expression) etc. to make it what is by and large becoming another spec series… this is what actually made manufacturers move away. Dr. Thiessen had once already said that whence F1 be dumbed down, BMW exits. The morons were discussing spec engines and gearboxes, and that’s when even Ferrari put their foot down and firmly.

    The reason why they cited financial meltdown, all of the teams who exited F1 that is, because it was bleeding darned convenient. I fail to come to terms with why people can’t understand this… it was not the money, they are still spending it, somewhere or the other… Just not in F1, as it is not the same and is losing charm and marketing value.

    1. BMW was on the eighth year of their five year plan to win the F1 Championship. They were no closer to winning the Championship in 2009 and Munich was right to pull the plug on the F1 program.

      Mario Theissen pinned all his hope on the KERS system and he went against all other team principals to press ahead with racing the KERS in 2009 and not delaying it. BMW rarely used its KERS system in 2009 and its system (along with the rest of the car) proved inferior and unreliable.

      The Mosley-spec engine and gearbox would have made F1 far less attractive to BMW, Honda, Toyota, and other car manufacturers. But I am certain that BMW would still be no closer to winning in F1, no matter what rules are in place.

      Yes, BMW is still racing in other categories, but they are in the lesser categories such as ALMS, the Hertz car series (sorry, the world touring car championship), and its only formula BMW series. All those activities don’t come close to the annual F1 budget of $200million.

    2. None of which explains why FOTA are still commited to cutting costs in F1.

      The sport is still far too expensive to compete in, for what is essentially putting two cars on a grid about 20 times a year.

      Neither Honda, Toyota or BMW are likely to enter F1 again until costs are brought down even more.

      Mercedes will be reconsidering their participation in F1 with regard to this seasons results. Rumour is that the ‘management’ were expecting to have won a couple of races by now.

      Renault are basicly 80% someone elses.

  28. What a waste…

    Jarno trulli and glock were the reason toyota didnt win races in 2009, the car was quick as qualifying times showed but they lacked the single minded commitment in the race. i was very dissapointed.
