Lexus IS-F Racing Concept coming to Tokyo Auto Salon

Lexus is gearing up for next week's Tokyo Auto Salon and has released a teaser image on its preview site showing the Super GT SC430 and the IS-F Racing Concept. Lexus hasn't released any details about the DTM-esque racer, but from the looks of its massively flared wheel arches, comically large diffusers and righteous wing, it's all business with a side of flash. Where Lexus might campaign such a vehicle is open to speculation and we'd encourage you to do just that in the comments below.

4-door ALMS?
I think yes.

ADTM? I think even more yes.

yeah the first thing you think of is DTM.
And really no reason we wont see this car in dtm (if they let it in) because toyota isn't new to jumping into random series
*cough nascrap*
So either way, supergt, dtm, alms, gt3, whatever just put it on the race track!

The car should have had bodywork like that from the get-go (minus the huge wing), a la the CLK DTM AMG.

yeah, cause huge wings are so cliche when they actually are functional.
Conor 6:12PM (1/05/2008)
It wouldn't be necessary on a road car, which would make it somewhat cliched. It would just be an accessory backing up the "look". Necessity is the mother of all invention. And wings were invented for applications that needed them and would utilize them. No road car is going to be "legally" turning into hairpins while braking from 100+ MPH, nor will it be involved in any of the other high-speed, high-risk situations race cars are subject to.

A wing the size of the one in the supplied photo would do nothing on the road aside from obstruct vision. A smaller wing or even a lip spoiler would more than suffice, and would still give more functionality than pretty much anyone buying the car would ever need. If you were a die-hard track nut, then it wouldn't exactly be difficult to buy a high-rise wing after the fact for actual track days.

I know this is picky, but there's no hyphen; it's IS F. Don't feel bad, Edmunds has it wrong too.

I wonder if this one has real exhaust pipes.

This one has dual-DUAL exhaust pipes. Think Pagini Zonda x2.
Conor 9:02PM (1/06/2008)
The zonda has 4 arranged 2 on top of the other in the center of the rear clip. With a piece of circular trim surrounding them. So what are you reffering to? That it has 8 pipes? Or that the IS F has 2 Pipes stacked on either side?

The IS F has "real" quad exhaust (2 x dual tips from each muffler though) , the tips are just not bolted directly onto the muffler to minimize the ugly gap between exhaust tips and the rear bumper.
I am sick of people saying they have fake exhaust tips when most people haven't seen the car in person yet.

Nice! It's great to see Lexus/Toyota taking on the Bimmers!

Speed TV World Challenge, GT class. Now that Cadillac is no longer campaigning the CTS-V, they could use another 4-door in that series.
Or whatever SpeedTV and the SCCA are calling it these days.

SC430 GT??? Wow that is going to be 1 ugly race car

It is, and it's been running in SuperGT500 for years now.
This IS looks like it has DTM aero. It's not a SuperGT car because of the double stack rear wing. The fender flares and diffusers ape the A4 DTM also. I'm not sure this is a real car... The level of race engineering and modification allowed in both DTM and SuperGT exceed those (by a good margin) allowed in ACO GT classes. (Though FIA I guess is trying to marry FIAGT1 and SuperGT500) ((which would be sweet)) (((might as well throw DTM in there too))) ((((supersweet))))

"The IS F has "real" quad exhaust (2 x dual tips from each muffler though).
Actually, the IS-F has semi-dual exhaust with quad tips. That means 2 16.8L mufflers with 2 tips. Real quad exhaust is something totally different, and something automakers have probably never produced. Most production cars have true dual exhaust, one pipe from each bank that doesn't converge and split like semi-dual exhaust , and has one muffler for each pipe (x2). Some have single tips, some have dual tips. So dual tips in that case would be dual exhaust. Quad tips would also be dual exhaust (or semi, in the IS-F's case), with dual exits on each muffler for a total of four. That doesn't make it quad exhaust. True quad exhaust means having split headers on each head with two pipes coming from each bank (2 cylinders for each pipe) of the engine using very small diameter pipes. Costly and space inefficient.

You're right except for the semi/true dual exhaust.
Real production cars have a true dual exhaust which means 2 headers on the 2 engine banks with 2 catalytic converters and a x pipe to converge the pipes somewhere behind the cats after the x pipe, the exhausts split again and go to 2 separate mufflers.
The X or in some cases for cost and space issues H pipe is necessary for flow issues. You should never have a dual exhaust without a X or H pipe because of the decreased efficiency.

I didn't know the IS-F could get any uglier. I was wrong.
