Lexus Steps Up: Said To Shoehorn The LF-A's Engine Into Upcoming GS-F

Reducing engine displacement... So what, it'll have 350ft-lbs?

big deal.

350 ft-lbs translates to well over 1000 ft-lbs after going thru the lower tranny gears + the differential gears.

with modern trannies, and ESPECIALLY the 6, 7, and 8-speeds on lexi, WHO CARES what the nominal torque rating is?

I actually like the lexus GS but hope they dont think for one second that squeezing a V10 in a car will help them beat out the M5. The M5 is the whole sports saloon package with handling,cornering,massive power etc...etc... and the price has to be comparable if the GSF is 200k and the M5 is 100k w/4 year maintenance warranty I would go for the BMW. I am think this thing will be one of the most powerful sports saloon next to the M5 and the RS6 but the true test is when its compared to others in its class

oh yeah its about time they are making a new SC the current one has been out for 8 years THANK GOD. If that car isnt showing its age i dont know what is

Why in the world do you think that a GS-F would cost 200k? Yes, the engine is a pricey component of the LFA, however, it's the carbon fiber, high-end materials and the fact that it's hand made that makes its so expensive.

Lexus will price a GS-F the same way they positioned/priced the IS-F against the M3. It's an obvious strategy.

lol xyzz, I tried explaining this to you before. I don't drive around town at 3500rpm.

then obviously joe, you just DON'T KNOW how to enjoy a sporty car!

SMART drivers of sporty machinery know they can rev up to redline in 1st and sometimes 2d, then do a DIRECT short shift to 5th to cruise along at legal speeds with NO ONE ELSE around them.

lol ya, but with a low torque car you are always forced to shift before you can have fun. High torque/lower rpm cars enjoy the benefits of being able to tap into their power without shifting.

then you should STICK TO trucks and old detroit barges.

drivers of REAL sporting machinery actually ENJOY all that shifting.

Well M3 has ONLY 295 lb-ft, less than that of 335. But is M3 slower?
That's when rpm comes into play.....

This thing is a heavy weight m5 competitor.

You seem to be good at missing/neglecting the point..... I'm using 335/M3 as 'approximate' analogy between M5 and this GS-F, at least in terms of torque, rpm, and gear ratio. With one 30 lb/ft more and another 1000 rpm higher redline, you never know till actually testing them. Check this video out:

G O T I T?

Then I'm still confused why you even brought it up. The M5 still has more power and torque then this GS.

Forget it.....

unlike the juvenile BENCH racers, badgewhore and i are more in touch with REAL WORLD needs.

no one REALLY needs gazillion tons of torque, OR horsepower.

to just maintain 55 mph, no more than 25 - 30 HP is actually needed. anything more is largely just WASTED energy. unless you wanna be a BOY RACER dragster. (and how much time does anyone spend accelerating, vs. steady speed cruising?)

xyzz, please... we know you don't care about fun cars so can you go comment on another site? Maybe a lawn mower forum?

Regardless of your point the comparison of the M3 and 335i in relation to the GSF and M5 is pointless. In the case of the M3 it has a significant amount of horsepower by comparison to the 335i and not much lower in torque. So of course the V8 powered M3 that is developing 114 more hp and only 5 less lb of torque than the 335i is the faster car. That small difference doesnt mean anything when it comes to 0-60 times with such a large horsepower advantage. This GSF will have probably 130 less hp than the upcoming M5 and based on current generations wont significantly less than the M5 to offset such a huge gain. In fact I would bet if the GSF actually has 450hp it wont keep pace with the current generation of cars in this class let alone the next generation. The 400hp twin turbo 550i and 380hp E500 will probably be just as fast......

E550 typo

dang we need an edit button lol..."wont weigh less than the M5"

I know, which is why I intentionally said 'approximate' and misses 'hp' in the sentence. Video comparison of Cayman S ad 335 is a better illustration.

lol that comparison is even worse, one the Cayman S is faster weighs less and is a 2 seater mid engined sports car, how on earth is that a relevant comparison in relation to 2 midsize sedans....please just stop lmao whats next the 550i and the 911 turbo

Why's there so many clueless guys? I'm using that just for powertrain parameter comparison, what's so hard to understand???

clueless....the comparisons your coming up with couldnt be more pointless. Compare like engines, cars with similar traits thats my issue with some people you know absolutely nothing about what your talking about, but are insistant on making comments.....seriously...

Lexus would be wise to fix problems with their bread-butter sedan, the ES before taking on BMW. Toyota really needs to focus at the issue at hand.

The GS looks a million years old now regardless of how fast it may be moving. LF-A should be cancelled.

adamsaf723,

The Acura TL is an AWD beast? LOL!!!! Tell me you are not serious. What makes it an AWD beast? Is it the 6.7 second 0-60 time? or is it the 14.9 second 1/4 time @ 95mph? You do realize that a V6 Camry, and a V6 Honda accord has better performace numbers? And that's what you call a beast. adamsaf723, it isn't a beast. Sorry to break it to you.

And Oh yeah... A 2001 BMW 330i also has better 0-60 and 1/4 mile times than a 2009 Acura TL. A 9 year old BMW from the last generation can outperform a 2009 Acura TL. Sad!

Gee, the new M5 will have near 600bhp, wonder how that'll play out for Lexus.

Dumb comment....
More HP does not mean faster.... In my mind it is just a stupid waste.
Plus if I had an engine that sounded like the LFA, that would be the ticket, period.

Not sure. I know it will have brakes though. SMH

the LF-A has arguably one of THE BEST engines offered in a car. and it makes all of its power NATURALLY, without benefit of artificial boosting by turbo- or supercharging.

the engine revs up TOO FAST for mechanical tach drives, and thus has an electronic tachometer.

with 200cc less, the GS version will rev even faster!

The good thing is new Lexus sedans especially IS and GS will be made from the beginning considering the respective F variants which will follow. This was not the case before so automatically even the forthcoming base models will be sportier/flexible than now.

No, thats what the ES and LS is for...

Good point...Infiniti should have beat Lexus to the game with an M3 competitor. The G is better suited for high performance than the IS.

"I don't know if it's a good idea for Lexus to build a better BMW, they can easily do it,"

- You sure about that? They haven't as of yet despite several attempts.

The current v10 has a 9000 RPM redline that is way too much for an automatic to handle. Currently only the Maserati ZF 6 speed can handle about 7200-7500 RPMs So most of the Detuning will be lowering the red line and making it more torque in the cam phasing and less top end hp....simple!

Another dumb comment....
Toyota is fixing 50,000 of their recalls a day. This will all be behind them sooner than you would like to think.

if such a dumb req't had been imposed on the D3, they all would've gone bankrupt DECADES AGO!

current recall is only 3rd largest ever, with ford and gm having #1 an #2.

and this is all over a MEASLY 34 fatalities. d3 defects have killed THOUSANDS over the years. 1,400 for the exploder/firestone alone!

Above 500BHP in this class every thing is okay. One example is 500BHP Panamera Turbo, i read in a magazine that it is around 20 seconds faster than 572BHP Audi RS6 around Nurburgring. Also Panamera has got double clutch gearbox(PDK) and RS6 hasn't.

Almost all cars in this class are 4 star cars. To earn full marks Companies should not just and only look at Horsepower numbers. Now it is very competitive and i am sure companies will bring/add newer innovations to these models like KERS, Hybrids, Start/Stop, better mpg, lower emissions...etc. These things even in this high performance category have become important/popular and will be crucial in one car's win over the other in the future.

Expecting lot of new features from both upcoming BMW M5 and Lexus GS-F and not only around 550 Horsepower.

450hp??? What is Lexus doing lately? how useless is that to have it compete with M5 and E63 that are over 500hps? Lexus gave the IS-F fewer power than its competitors that's why it lost the battle and now they want to loose another battle. This is not making any sense. Don't build the damn thing.

Wow, some people on here really don't know what they are talking about.... The IS-F has more HP than the M3 and did not loose in performance. Where it lost overall in its first year was ride quality or feel and overall appearance, otherwise the IS-F did succeed in exactly what it set out to do and that was to out perform the M3. The M3 is faster above 70-80 MPH up to it's top speed but the ISF has a higher governed rev limiter thus higher top speed than the M3.

Show me a single source that showed the IS-F outperforming the M3.

A Lexus topic worth discussing? I thought I'd never see the day!

are you serious lacman? the IS-F has more HP than the M3 and the RS4, only the Mercedes C63 has more. If anyone read the article it not only says the lexus will have at least 450HP but it will be significantly lighter. I'm guessing it will save at least 150 pounds off the curent weight. Which is 3900. A 3700lbs. car with 450HP will probably perform better than a 4100lbs. car with 550HP. Plus the torque sensing whatever for the rear is pretty much a super LSD. I'd rather have N.A. than a turbo or supercharger. The LFA put it right. Rather than go all out with the HP wars and make 800HP, they lessened the weight, gave it good downforce and was able to make it 3 seconds faster on the wet top gear track than an almost equally powered 4-WHEEL DRIVE Gallardo. There's a good example of useable power.

" I'd rather have N.A. than a turbo or supercharger."

- Outdated ideology.

I wasnt talking about the IS-F. In fact, I totally forgot about that car. Sorry. (well then again, seeing how forgettable it is shows you how much that car has mark on its category)

Why are people so worried? The Current Lexus GS lit the world on fire and sent the 5-series and MB E-Class back to the drawing board. Wait... It didn't. Nevermind.

Putting an LF-A engine in an old outdated car will do nothing but excite the clueless Lexus Fanboys.

lol dude if you look up 'fanboi' in a dictionary, your picture is there

Lexus customers are not fanboys. They are regular nice people who want a quality product.

What is an old outdated car? The LFA engine will go into a brand new model GS which we will see in less than a year from now.
