Lexus is teasing a new mystery model that will be making its debut at the upcoming 2015 Detroit Auto Show.

Lexus_F_15NAIAS_002The Japanese company is only letting on that the new model will be part of the ‘F’ brand, which means it’s built to go fast around a racetrack. Currently, the company sells the RC F Coupe, which packs a 5.0-liter V8 that makes 467 hp and 389 lb-ft of torque.

From the look of the photos, the new car in question may be the rebirth of the IS F, which would essentially be an RC F with four doors. However, it may also be a performance version of the company’s larger GS, a car that has been rumored for some time.

Whatever it is, AutoGuide will be live at the Detroit Auto Show to get you all the details.

The nose's hideousness will increase in direct relation to the car's level of track readiness.

Some are saying GS however the picture above is obviously that of the IS/RC and not of the GS. Unless that picture has nothing at all to do with or the GS F is dramatically different from the standard GS then it is an ISF.

I'm just gonna guess GS F. It could be the IS F or some kind of specialty RC F variant, but it seems to me that it'd be the GS F based on the media covering GS F mules driving around and a wait for a GS F and facelift lines up here. But unless they're gonna put it next to the S6 in price, the GS F is gonna need a lot more than the brand's current flagship V-8, the 467 horsepower 5.0L. That thing needs a supercharger or a pair of turbos. The platform already has fantastic handling with the GS350, so that's not of concern. It's mostly the "go" that needs to be addressed. In a world with 707 horsepower Chargers and established RS/M/AMG divisions, Lexus has their work cut out for them with making F properly special. Cadillac was able to do some of that by packing massive power in the CTS-V from day one (2004), although V-Series too has more work to do.

And maybe Lexus should go in the super-tech route (which I doubt they have) via a performance hybrid engine as Porsche (918) and Ferrari (La Ferrari) have done. Take the RC F's 5.0L and use a couple of electric motors and we're easily talking 700 horsepower. Now people are watching. The standard FI V-8 with 575 horsepower would be great, don't get me wrong, but that's (and I can't believe I'm saying it) conventional in this segment. Lexus can't be conventional here, and based on their styling trends they already think that in general they cannot be conventional. Soon enough we'll see what they are doing, but a landmark change in this segment's level of power and efficiency would be awesome.

I think the costs are too high for Lexus to go with a hybrid GS F
Acura has the RLX Sport Hybrid, which is a 60K hybrid that has a V-6 and three electric motors. Instead using two larger electric motors that contribute much more power each (as Porsche's one engine, two electric motor strategy), that should be more than enough for Lexus to be able to charge 90K for a seriously powerful GS F. Similarly, the GS450h is a 60K car, and all the performance additions should be good enough for another 30K. No doubt, my suggestion is more costly than high-pressure turbos, but as I speculated before Lexus is going to need something for attention and that will give them a lot credibility if there's an efficient, yet exceptionally powerful and unique offering in the segment rather than another 5xx horsepower sedan that might make more per unit sold but will gain less fanfare and resulting sales.

Its easier to add to FWD vehicle than a RWD. There's no rear diff or much equipment in the way.

Then use various, much cheaper examples RWD platform:

5-Series Active Hybrid (twin-turbo hybrid no less)
E400 Hybrid
Q70 Hybrid
GS450h

All cars that fall in the 50-60K range. There's no way Lexus can justify the GS450h at 60K but not a 90-100K version with "e-AWD". Lexus' only limitation would potentially be packaging (I think Lexus already has an issue packaging the 8AT with AWD in the GS350), but tech-for-dollar is not an issue. And if they skipped the AWD version that should eliminate some of the issue anyway. The AWD would've been more of a bonus and allowed for more/bigger electric motors, but I'm not saying it has to be done that way exactly.
