There hasn't been any news on a Lexus racecar since we heard rumors that the IS-F racer, unveiled at the Tokyo Auto Salon, was really a reskinned 2004 Opel Vectra DTM. While Lexus might not be supporting a factory-backed motorsports program for the IS, that doesn't mean that privateer teams can't develop a car on their own. DRC Motorsports has done just that and has built two IS 350 racecars that will compete in the GT class of the SPEED World Challenge. Dubbed the IS GTF, it will be sporting a 4.7-liter V8 putting out 510 horsepower and attached to six-speed sequential transmission. The first car will make its debut this weekend at Mid Ohio with Jeff Altenburg, last year's SWC Touring Car champion, behind the wheel, and the second car, driven by Robb Holland, is scheduled to make its maiden run the following race at Road America. Both cars are scheduled to run the remainder of the race season. If you want to watch the new IS GTF in action, SPEED will be airing the race on Thursday, July 24 at 1:00pm (EDT) following the Touring Car race.

      That looks like a mid 90s M3 race car.
        • 6 Years Ago
        I was going to say it looks like a rice boy's poor impersonation of a M Coupe.

      Is that the Team Lexus IS350 GT2, now called the IS F? It still has the IS350 hood on it.

      If so, it's glad to see them finally go racing.

        I think they look very similar to. That is what I was wondering, if they modified the Team Lexus IS350 race cars that they built.

        I'm also curious as to why the engine is 4.7L. Did they modify the 4.6 V8? De-stroke the 5.0? Why didn't they use the grandam engine which is basically an unlocked version of the IS-F motor?

        What are the regs wrt to displacement in this racing series?

        Hmm... after reading the my IS post, it seems it's not the same team. But the two cars just look too similar - the arrangement of the louvers on the hood, the roll cage, the piece that connects the roll cage to the A-pillar... maybe the same cars (since Team Lexus have prepped a few already) but different team?

      It looks like a M3 race car, or Merc CLK race car, or Opel race car. Oh wait, of course it is going to look like those, it is a race car. And I assume the louvers have a purpose.

      Or like the M3 ALMS that was presented a few days ago.

      I got a fever... prescription... more louvers...
      • 6 Years Ago
      This is great to see. The amount of louvering is insane though. Kinda strange to see a Speed GT car so tubbed out, most cars in this series don't have that much wheel arch modification, although a couple (mostly the CTSes) have ridiculous amounts of other changes versus stock.

        Its the SCCA... if you pay them enough... they give you an entry form! Look how different the SWC/ GT Cadillac CTS-V racer is from the SCCA T1 or Grand Am versions.

        I like the Cadillac & that GM supported the series... but the SWC is suppose to be a production based series. The Lexus & the CTS-V don't look much like the street models they are representing.

      lexus IS-F = IS FAIL

      god that thing is hideous. pretty sure the new M3 ALMS, with all its aero package, is much faster

      A few tidbits from my.is answers a thing or two

      "On the other hand, Grand Touring (GT) class rules are much broader, including a variety of production displacements with no maximum. Forced induction is permitted and is used to equalize individual models. Sedans, coupes, convertibles and two-seat models are permitted. The cars can be rear-wheel, or all-wheel drive. Class horsepower range is 350-550 bhp.

      At this time, fully detailed specifications are not available, but we do know that the SPEED World Challenge Lexus IS GTF, which was engineered and built by Greg Fordahl and the team at Redmond, Washington-based Fordahl Motorsports after an almost year-long effort, will be running is a purpose-built 4.7-liter V8 race engine that puts out just over 510 hp via a Hewland 6-speed sequential transmission. The base weight for the car with driver is about 2900 lbs, and this is one of those racing series that uses the same spec tires for all, in this case Toyo Proxes RA888s, in a 295/35-18 size for the front and 335/30-18 for the rear in the IS GTF."
