Lexus GS 450h - Click above for high-res image gallery

It looks like Lexus is planning to go to both extremes on the green-performance continuum. When the next-generation IS appears in a couple of years, it will likely add a hybrid powertrain option. Such a move would be in keeping with Toyota's oft-stated commitment to having hybrid drive available in almost all of its platforms by the end of the decade. The IS hybrid may also spawn a new rear-drive hybrid sports car around the same time. If these IS based hybrids are consistent with the current GS450h they will definitely be biased more towards performance than efficiency, using the hybrid drive to enhance acceleration without consuming more gas.

Meanwhile, the GS – as rumored previously – could be setting its sites on the new BMW M5 and Cadillac CTS-V. Even though only 500 LF-As will be built, the 4.8-liter V10 may find its way into a much-rumored new GS-F model. The GS-F won't arrive until 2013 so it should be based on the next generation sedan. In the LF-A, the V10 has the power to compete with the German and American models but falls short of the Cadillac's torque. If the new M5 gets the uprated 4.4-liter twin-turbo V8 from the X5/X6 M, it would also be way ahead of the Lexus. Unless the Lexus engine gets boosted or the GS looses a lot of weight, this could be the only high-revving sports sedan of the pack left.

      We now know where the tooling from the old Ford 500 went.

      Lexus messed up with the HS. They made a more expensive Prius with worse gas mileage. WTH? They should have made an IS that gets 50 MPG, now THAT would be something.
        • 4 Years Ago
        You forget. Hybrids are a waste of money for the consumer. They should be cheaper than their gas only counterparts. A 10,000 dollar premium over the standard gas only version negates all gas cost savings, not to mention a heavier car. People want to save money with hybrids not spend more.
        • 4 Years Ago
        I believe that it's relevant to how long the consumer owns the car. I agree that $10,000 is too much "extra" to pay for a hybrid, however I'd pay $5000 extra for a hybrid. Lexus could also allow consumers to cut corners by unchecking leather, larger wheels, and a 16 speaker stereo system.

        So if you save $100 a month on gas, then that's $1200 per year, after 5 years you have saved $6000 and after 10 years, $12000. I usually keep my cars closer to 10 years so it would be worth it for me.

        I have already passed the 5 year mark on my TL and I'm not even thinking about selling it yet. My next car is going to have to be a Volt/ Leaf/ Karma type of car to get me to get rid of my current car. Lets see what's out there in 2014.
        • 4 Years Ago
        You forget about the life of the battery. You won't get that much consistency in gas savings over 5-10 years. Repairs and replacement on a battery isn't cheap. Another point is your TL doesn't have a battery. I would buy your TL from you for a fraction of the price of the hybrid Lexus and save a ton. And to my final point, Lexus would NEVER let you uncheck leather or those other options you listed so that's out of the question. Lexus "could" but never would. Hybrids=waste of money for the consumer, unless they are cheaper to buy initially by several thousand compared to the gas only version of the same car.

        Taking away the luxury and performance features from a Lexus leaves you with an economy car, not a luxury car. Bad idea.

      "setting its sites on the new BMW M5"?
      " the GS looses a lot of weight"

      Who wrote this? A sixth grader?

        My thoughts exactly... This together with the Hummer post with a first sentence that doesn't make sense makes me shake my head a lot reading AB today... :)

      The headlight was meant to elucidate that Toyota is working on a RWD HYBRID, in the form of an IS, not that the IS was going to become RWD, as you point out, already is.

      And how is it that the Lexus GS hasn't been updated or refreshed in so long?

      I wouldn't mind seeing the design for the next gen GS before hearing about a GS-F based on it.
        • 4 Years Ago
        BoxerFanatic,

        Since the 2nd Gen GS lasted 8 years, the 3rd Gen is due to be replaced in 2013.


        Moe,

        Having a hybrid IS makes sense in the lineup. The IS/GS/LS hybrids offer performance. The HS/CT offer economy.
        • 4 Years Ago
        BoxerFanatic, what are you talking about? The GS was just refreshed a few months ago.
      • 4 Years Ago
      Comes equipped with unintended acceleration as standard equipment along with a printed BS apology in the glove box.
      • 4 Years Ago
      Now you morons might finally be able to figure out what the LFA was all about. Once Toyota puts some of that technology in their regular lineup the R&D costs will be paid back many times over.

      The LFA is a collectors item for rich folk, but the technology will benefit everyone.

      This is really getting kind of stupid. They already said that the LFA engine won't be put into the GSF on Autoblog.

      Also, it makes no sense to put that high strung V10 with low torque in a heavy sedan. Crossplane V8's are best for a smooth, high torque application like a sedan. The V10 makes sense for the LFA, but that car has the dynamic capabilities to match. The GS doesn't. No sedan can really make use of that V10.

      The most common sense approach to the GSF is to make a twin turbo version of the ISF's V8. You could likely get 500bhp and 550ft/lbs out of that engine. That would be the best way to make a performance sedan above the ISF.

      I think that Lexus has been catering to the ignorant buyers to the point of pandering. The hybrids they offer make no sense, as the LS460 and GS460 both get about the same fuel economy and have better performance/driving dynamics than the LS600h and GS450h! The HS doesn't drive like a Lexus and the 4cylinder engine is unrefined.

      They really should stop with all the hybrid BS. Lexus used to have fantastic inline 6 engines. My IS300's engine is fantastic. Toyota made a direct injection inline 6 but Lexus switched to V6's shortly after. They really should have developed the direct injected inline engines, added turbos and they'd have a much better lineup than their current one, and better than the rest of the carmakers too!

      The next GS having an F variant is a good idea. They could improve the lineup by bringing a new SC back as either a proper roadster or a proper GT, not something that tries to be both. The IS, GS and SC could all make use of a good inline 6 with sequential twin turbo as an option. i.e. IS300, IS300TT, ISF. GS300TT, GS460, GSF V8TT. SC300TT, SC460, SCF V8TT?

      Really, those engines would be much more enthusiastic and would be able to offer the smoothness and lower reciprocating mass of an inline 6. The turbo option would replace the 3.5L V6. They could easily use a twin turbo V8 in the GS and next SC to make F variants.

      All the F models could benefit from CFRP bodywork, like hoods, roofs, trunks and door panels(painted and maybe unpainted as an option if it's done tastefully). CCM brakes could find their way into the LS, GSF and SCF(VW managed to use them on the Phaeton).

      All of these technologies would also be able to find their way into a Toyota Supra. Can you imagine a 3L TT inline 6 powered Supra with an option for a TT V8 with CFRP bodywork? If Toyota wants Lexus to keep a competitive edge against the Germans, they really need to cater to enthusiasts and not just the hybrid phony environmental crowd.

      To me, those ideas sound a lot better than more stupid and pointless hybrids. The thought of driving a turbo IS300 makes me want to trade my IS250 in. I don't get excited at the thought of a hybrid IS that handles worse than the car I have now. I will never trade my IS300 Sportcross, and I doubt Lexus will ever make cars like that, in that price range again, if all this hybrid nonsense keeps up.

        No inline 4 with balancer shafts can match the inline 6's inherent balance or power overlap. I know packaging those engines is harder, but if BMW can do it, Lexus should be able to... and has in the past. The regression to cater to idiots who want rolling PC entertainment systems and hybrids pisses me off, because the IS used to be a proper sport sedan.

        My old IS300 is ironically nicer than my brand new IS250. I don't think that Lexus should attempt any more 4 cylinder engines, given how awful the one in the HS is.

        But as far as packaging costs and difficulty, how hard is it to make a V8 hybrid system or a 5L V8 fit under the hood of an IS compared to putting an engine that's fairly identical to the old Supra engine in the same engine compartments? Lexus is just being cheap by offering V6's instead.
        • 4 Years Ago
        @invisiblepigeon3
        Forget about an I6. Packaging that type of engine is far more difficult than an arguably inferior V6. I think this is why there's so much interest in I4 engines. With today's technology, a forced induction I4 can easily make the same kind of power as recent model N/A I6's and V6's. Hell, some are even capable of the same power levels of some semi-recent model V8's. In my mind, the problem is selling this type of engine package to an enthusiast crowd. The average buyer, wouldn't know the difference but the enthusiasts (like myself) just love the beefy exhaust note and broad powerband of the larger engines.
        I for one, wouldn't give up the V8 in my Cobra for a TT 4cyl. no matter how much power it supposedly offered.
      • 4 Years Ago
      I thought Lexus already said the V10 in the LFA will stay exclusive to the LFA after the first rumors of a GS-F popped up?
        • 4 Years Ago
        Thats what I thought too, though now i can't find the article.
      • 4 Years Ago
      Don't they have a Diesel IS in the European market?
      • 4 Years Ago
      I've always liked the GS. Since it's introduction it's served as the slightly cheaper and more daring alternative to the slab-sided LS, and even the first-gen model remains a fresh and beautiful design. Unfortunately it's never truly stirred the hearts of enthusiasts with its detached driving experience. I hope the future GS retains its distinctive short rear deck and fastback slope, but would welcome a more aggressive front fascia and more communication between man, machine, and tarmac.

      While the small-displacement V10 was bespoke for the LFA, I highly doubt with so much invested in it they'll just retire it when LFA production ends. I really hope it ends up somewhere, because it's a brilliant motor.
        • 4 Years Ago
        I agree, the GS has always been the only Lexus I really liked. I wish they'd add twin turbos to the IS-Fs V8 rather then try to go with the V10. I imagine that would make the car very expensive and not give it the character the other cars have in that segment.
        invisiblepigeon3
        • 4 Years Ago
        They already said on Autoblog that the V10 won't be used in the GSF. I don't know WTF is up with this article at all.

        The ISF's V8 with twin turbo's would be brilliant in a GS.
      • 4 Years Ago
      Yes, but will it brake?
      • 4 Years Ago
      The front facade of that GS is painfully ugly, while the rest of the car is painfully bland. I sure wouldn't mind one with a V10 though, but can't imagine why someone would pay for that, given all of the other options out there.
