I'm pretty sure the 4.6 can comfortably put down 400hp with an excellent powerband and better torque than it already has.

A forced induction 5.0 would be excellent for a GS F though.

 

The New Lexus GS Caught Testing

Here you can see the 1st spy photos of the new Lexus GS, taken today by CarPix spy photographers. These pictures surprise the car while it takes some laps around a rainy Nürburgring in Germany.

Even if the car is covered with that dense, black camouflage, we can easily see, that it look alot like the Lexus LF-Gh concept car that was shown earlier this year at the New York Car Show.

The next generation Lexus GS sedan expected to launch in time for the 2013 model year. At NY Car Show, Lexux LF-Gh showcases a number of new design elements that will proliferate across the Lexus lineup in the coming years. Most important is the spindle-shaped grille that dominates the front fascia, which is flanked by full LED headlights with L-shaped LED running lights. Except some changes (particularly its character lines, roofline, and proportions) borrows heavily from Lexus’ flagship LS range.

The brand stated (before the concept has been shown in NY) that the interior will be a meticulously designed and engineered cabin using the highest quality materials. It has “re-examined every detail of the interior, with the aim of making [it] driver-focused.”

Considering that the exterior at least is very similar with LF-Gh concept car presented in New York this year, we can suppose that it will keep the same dimensions and features as the concept. The car presented in NY was 192.5 in. long and 73.6 in. wide, the LF-Gh is roughly 2.5 in. longer and about 2 in. wider than the current 2011 GS 450h hybrid sedan.

For now we do not have the official specifications, but with roughly the same dimensions, we expected this car to use an updated version of the 292-bhp 3.5-liter V-6 engine and CVT automatic transmission found in the GS 450h.

We will keep you in touch with all the information that will appear. Until then you can watch the most recent spy pics with the new Lexus GS in the gallery below.

 

Can see the LEDs., gained the Lexus side view mirrors detached from the body..seems to have maybe a 19" version of those 18" iS F split spokes of the past....I also see amber turn signals and the rear lower bumper seems to incorporate integrated exhaust

 

This model sits lower than the other one we saw, must the RWD

 

That is the same mesh grille as the ISF and IS F Sport, so I wonder if this is the GS F Sport? I'm kind of surprised at how much it actually looks like the LF-Gh...not that we didn't know it would, but it's incredibly similar. Front end will be very similar and you can see the kink in the side skirts as well. Shape of the rear valence is somewhat similar too.

 

Those LED's look terrible, couldn't they go the Audi/Cadilliac/Volvo route and put tube LED's? Also the back looks straight BMW.

 

Not a fan of the LEDs (or the exterior really). I'm hoping for big things from the interior.

PS- I really liked the original wheels on the SC430. Never understood all the hate.

 

The spindle grille is very much intact. And headlights look like LEDs to me, so this is the hybrid that they are testing around the track.

 

LEDs look like those on the old A6...old school. They need to do them like the 2IS.

 

I was really hoping they would evolve from the previous GS. This car, if it turns out to be a 4GS, looks quite different than any GS we've seen. Not sure if it's a good thing or a bad thing?

 

Nice to see the GS/GSh is being tested with a BMW 5-series.

 

Was looking at this site and found that the spy shots show the rear lights to be the same as our GS's I thought the new GS had the third brake light on the roof like the LS!

even the fog lights area looks shaped the same... which is actually very good.

i think GS should look agressive from day one, like it eats babies for breakfast.

 

There's still a lot of camo on the headlights I wouldn't judge them until production.

All I can tell is there will be LED strips underlining the highbeam/lowbeam/signal cluster. Highs and lows look to be projectors.

 

i am not a fan of the led setup on the current IS, and don't like the leds on the test mule so far either. wonder what the final would be
