The Lexus LS is supposedly in line for a V6 engine. The suggested powerplant is Toyota's 3.5-liter unit tuned to produce 310 hp and 278 lb-ft of torque. A comparable car would be BMW's 740i, offered in Europe with a 3.0-liter inline putting out 326 horses and 332 lb-ft. The Toyota's numbers are down slightly, but since the V8-powered LS460 already weighs less than the BMW 740i, the additional weight savings of a Lexus V6 should allow it to move along just fine.

If a V6 LS does bow with the coming, facelifted car, we might not see it in America. The trend among automakers is not to bring their frugal luxury to our shores; BMW also offers its 7 Series in Europe with a 3.0-liter diesel, for example. On the other hand, the six-cylinder LS could help dress up Lexus's CAFE numbers, and assuming California's new, more restrictive emissions standards get the green light, we think that might make a V6 LS even more likely.

      I'm sure lotus is hoping this powerplant comes to fruition for their new coupe.

      I think you mean 278 lb-ft of torque. 378lb-ft would be damn impressive out of a naturally aspirated 3.5L V6.
        • 5 Years Ago
        378 lb-ft would be out of character and scare geezers? This class of car is about effortless excess.

        The existing V8 delivers 380 hp, 367 lb-ft. Which is in no way out of line with the competition.

        • 5 Years Ago
        I agree with 278 ft lb as well. 378 would be way out of character for a Lexus, grandpa might have a heart attack with that much torque.

        BMW V-6? you're on crack

        "A comparable car would be BMW's 740i, offered in Europe with a 3.0-liter V6 putting out 326 horses and 332 lb-ft. "


        what's a V6?
        • 5 Years Ago
        The Ls is HEAVY.

        Anything less than a Twin Turbo V6 wouldn't even be worth looking at.
        • 5 Years Ago
        This is an example of how many facts you can get wrong in 2 paragraphs, a BMW having V6 and the Toyota 3.5l making almost 400 ft-lbs of torque!

        Might as well say the car flies as that is about as accurate as all the other facts in this - quality on the writing is falling off lately!
        • 5 Years Ago
        Or they could simply 'cut' the LS. Nothing but a bloated road baleen.
      • 5 Years Ago
      yeah 378 would need some form of power adder.

      I think the current power is 278 of twist...
        • 5 Years Ago
        I read somewhere that the V6 could be paired with a Hybrid system, to provide the motivation this big car needs.

      Because what I always thought is "This Lexus needs to be slower."
        • 5 Years Ago
        @HotRodzNKustoms
        Given their reputation for squidgy handling you may be right.
        • 5 Years Ago
        @HotRodzNKustoms
        I'd venture to guess that most LS drivers rarely use a significant fraction of the V8's available power... the V6 would be fine, especially if it weren't obvious that they bought the "bargain" version so they could still look all showy down at the club.
      • 5 Years Ago
      i doubt this sells in the US , but in japan or china its possible.

      In china they sell like a 728iL and a S350...
      • 5 Years Ago
      The real problem, as with the Acura RL, is that all the other boys in the country club locker room make fun of you if you have less than 8 cylinders. So a 6-cylinder LS is going to be a car for the gals, leading to the question, is the target market large enough to make it worthwhile?
        • 5 Years Ago
        Hey they get to make fun of people who purchase the new 7-series.
        Nice 8 speed auto you got, oh wait, you don't have an 8 speed automatic. (BMW is waiting on start/stop functionality. Like mileage is super important to people in the 60K+ price strata)
        Come on the S-class may only have a seven speed auto, but at least it has two reverse gears.
        (It was very disappointing that the '06 S350 (V6) didn't have the 7g-tronic)
        • 5 Years Ago
        Times are tough right now and restrictions are getting stricter. Lexus may have enough people in their target market studies to justify this smaller engine right now.
      • 5 Years Ago
      Great idea, though I think the lack of maturity in America's consumer class (as evidenced by posters in this article) blinds people to the benefits. Toyota should expend some of its considerable marketing muscle converting the doubtful back to efficient luxury products.

      Right now minimal is the new zeitgeist, why not capitalize on that?
        • 5 Years Ago
        Thank you akboss.

        Clearly Toyota (and the rest who will likely follow) have an uphill battle convincing the buying public that perhaps a smaller engine is OK after all.

        Nevertheless its a rare opportunity to shift attitudes. There's no reason a small engined car has to be a "base" model. Indeed maybe a smaller engined LS could be bundled with a raft of tech toys and premium options as standard.
        • 5 Years Ago
        Never mind subprime lending and the associated derivative fraud, never mind short sighted fed manipulation of interest rates, never mind 3 billion people in the developing world, the real reason for every global ill today is irresponsible Americans buying two extra cylinders!

        Have some perspective.

      • 5 Years Ago
      I think this is great, from two angles.

      First, it's another option for those who say they want to tread more lightly on this earth and/or save a little money.

      Second, this will be a great test as to whether people will actually buy a car like this in the US. People get all jealous of the fuel economy of European-spec vehicles, but there hasn't been any evidence that people will actually follow through and buy these slower but more efficient vehicles. This will be a great way to find out.

      I personally don't think it'll sell much at all. This car is far too expensive for any "economy" version to really be adopted.
        • 5 Years Ago
        Nice post, and I agree completely. I think we have been conditioned by a gluttonous mentality towards luxury. Somehow because its a 'luxury car' it is supposed to have an 8, 10 or 12 cylinder engine. True, the buyer of a luxury car is paying a hefty sum and should be rewarded with a responsive and luxurious car, but that doesn't mean it has to have any specific number of cylinders - its a bold move for Lexus and a good one. Audi is also following suit, actually reducing the horsepower in their next S4 (I think? Or is just the new A4?) but compensating with a stiffer chassis, upgraded suspension and lighter materials. Europe has done with smaller engines in luxury cars for a long time, they don't complain.
      • 5 Years Ago
      You buy an LS for gas mileage? How much cheaper could it be?
      • 5 Years Ago
      Unless they are dropping the MSRP by close to 10K, is not a good idea.
      • 5 Years Ago
      V6 isn't a bad idea, lower entry point (maybe) and better CAFE standards
      • 5 Years Ago

      Seems quite adequate for a car that focuses more on luxury and plush ride than sporty feel or sharp handling.
