Lexus to get Turbo-Charged Four-Cylinder Engine in 2014?

Lexus ES 300h Engine

Last week at the Paris Motor Show, Lexus announced a new 2.5-liter hybrid engine that will be introduced into the lineup next year — now Toyota has released a couple more details:

An enhanced engine for use in hybrid vehicles, based on the 2.5-liter AR gasoline engine, adopts the Atkinson cycle and D-4S system. The enhanced engine achieves the world’s highest maximum thermal efficiency of 38.5 percent, realizing both high fuel efficiency and high output. Hybrid vehicle models equipped with the engine will be launched starting 2013.

Still no mention of the hybrid engine’s total system output, but early estimates have put it somewhere between 220-225 horsepower.

Also announced is 2.0L turbo-charged engine (!!!), set to debut in 2014:

Starting 2014, [Toyota] plans to launch a vehicle with a new 2.0-liter, turbo-charged AR engine, also based on the 2.5-liter AR gasoline engine. The new engine’s smaller displacement will provide higher fuel efficiency while the turbocharger will improve output.

While it remains unconfirmed, the 2.5L hybrid engine should be used in the next-generation IS and the current GS — considering compatibility, this would make both models eligible for the new 2.0L turbo-charged engine in 2014.

(The front-wheel drive ES and RX are also available with AR engines — the ES 300h and ES 250 in China, and the RX 270 in various markets. However unlikely, these two models could also be offered with the turbo-charged engine.)

These two engines are only part of the announcement made by Toyota regarding their technical development timeline — I recommend reading through the full press release, as it details much of the company’s future plans.

  1. YESS!!!! Turbo!!! I hope they put more than 225hp in the hybrid engine make it at least 250+
  2. aww WTF I just bought a 2013 RX 450H and now there going to roll out a more efficient one CRAP
    • Dude, chill.  This CUV won't be launched till 2014 at the earliest.  Some reports indicate 2017. The 2013 RX 450h is an excellent vehicle!  If you really want the new Lexus "NX", you can trade in your RX in 3 years time and still make a "profit".
  3. 2.5-liter with forced induction is a good choice , or maybe 1.8-liter to 2.0-liter with forced induction ... this made country with taxes that included factor of displacement have an big advantage , that's also the reason why Lexus weren't that good on sales on country that have displacement taxes .
  4. Maybe a CT200turbo... and 250h , maybe IS200 turbo...hmm
  5. I don't think it would make sense for the GS to have a 4cyl hybrid engine. They currently have the 2.5L V6 engine as a base model engine in some countries.
  6. Finally!!! That means I definitely need to replace my CT when the turbo version comes out.
  7. They might also use it in the RX and the new compact SUV.  It matches this report from the Bangkok Post: Lexus's product offensive in Thailand Within the next three years, the Lexus division of Toyota Motor Thailand is embarking on a product offensive to help build market share in the Thai luxury car market dominated by Mercedes-Benz and BMW.At the Thai launch of the all-new GS executive saloon earlier this month, Lexus announced its intention of moving in more than 1,000 cars this year with additional help coming from the RX sport-utility and CT compact hatchback.From next year onwards, Lexus hopes to push the envelope further by launching a raft of all-new models and new technologies more consistent with the tax structure on automobiles in Thailand.Life talks to company insiders to see what's coming by 2015.ES REVIVALNow that Lexus is left with space in pricing terms beneath the 4.5 million baht GS250, room will be made for the all-new ES. Although the ES once came to Thailand in fourth-generation form, today's fifth-gen member isn't made in right-hand-drive form. However, that is set to change as Lexus is seeing a substantial demand for it in India which has a huge right-hand-drive car market.Since the front-wheel-drive ES is essentially a reworked Toyota Camry _ the last ES350 in Thailand had a 3.5-litre V6 engine _ the just-launched all-new Camry will lend its running gear to the sixth-generation ES. Due next year at the earliest, the ES will be getting the 2.5-litre engine, as well as its hybrid version. Their potential badges are ES250 and ES300h.With estimated prices in the 3 million baht range, the ES will suit both fleet and private buyers who aren't too concerned about driving dynamics. The ES is a rival to the Volvo S80; the GS rear-driver will be left to the more sophisticated set of punters usually going for the BMW 5-series and Mercedes E-class.Also proposed is local assembly for the ES in Thailand _ a first-ever for Lexus _ although the decision is yet to be final. The business case calls for 1,000 (500 for each ES version) to be made per year. Economies of scales will be boosted by the fact that the Camry is built in the country.GS EXTENSIONThis year, there will be three versions of the GS to choose from. Apart from the GS250 and GS350, the hybrid-powered GS450h will join the Thai lineup next month.Lexus has already announced 7.79 million baht for the GS450h whose high price is attributed to the 50% excise tax it faces. It can't attract the 10% rate for hybrid-powered cars due to an internal combustion engine exceeding 3,000cc (it has got the GS350's 3.5-litre V6).But by late 2013, a high-ranking official conceded that there will be a smaller hybrid-powered GS in the guise of GS300h that can get the 10% rate. Though mating an electric system to the GS250's 2.5-litre V6 sounds logical, the source said the GS300h would be getting the Camry Hybrid's drivetrain. Even though the ES and GS have different driven wheels, the change from a transverse to longitudinal layout for the GS is said to be possible.The GS300h could be priced in the low 4 million baht strata to attract customers of the diesel-powered versions of the BMW 5-series and Mercedes-Benz E-class. BMW's pending 5 ActiveHybrid is intended as an image-booster for the 5-series range and goes in direct contention with the GS450h.DOWNSIZED MOTORSLexus has been slow in joining the engine-downsizing trend, so as to explain the modest 2.5-litre V6 engine and 2.7-litre inline-four petrol engines in the entry-level GS250 saloon and RX270 sport-utility.However, Lexus (and Toyota engineers) aren't sitting still. When today's RX expires in 2015 _ the facelift comes later this year but not in time for the Bangkok motor show this week _ a smaller 2.0-litre engine is expected to emerge.Featuring Toyota's double variable-valve timing (VVT-i), D-4 direct-injection and turbo technologies, the new unit will be capable of producing outputs of anywhere between 180-220hp.Since the RX270 is subject to 40% excise tax, the all-new fourth-gen RX could be almost half-a-million baht cheaper due to a lower 30% (25% if E20-capable). And at 3.5 million baht, the next RX petrol-turbo could play ball with the Thai-built BMW X3 in price even though the German SUV gains a small advantage with its diesel-turbo power.But before that happens, there's a likelihood that the new 2.0-litre block could appear in a brand new entry-level Lexus sitting below the RX, utilising a platform from the next-generation Toyota RAV4, rivalling the BMW X1 at under 3 million baht and targeting rich urbanites.Using the same motor for cars competing in different classes isn't unusual. The X1 and X3, as examples for SUVs, share the same diesel engine in Thailand.MANDATORY REPLACEMENTSSince the IS and LS model ranges are exhausting in their current generations, the all-new replacements are set to be revealed in less than a year.The IS will continue to please driving enthusiasts yearning for an alternative from the 3-series and C-class. Expect a hybrid version, too, apart from the usual V6 petrol power.The LS will serve as the usual flagship saloon to sway buyers of the 7-series and S-class. Although the Thai Lexus office had requested for six-cylinder power from its parent firm, it's still not confirmed yet whether the engine menu will stretch below the LS460's V8 in fifth-gen form.

    I doubt that Toyota will put the turbocharged engine in Lexus vehicles from the beginning. I even doubt they will put in the turbos at all. Lexus is known all over the world for building the most reliable cars. A turbo engine is anything but reliable. BMWs are changing turbos every 30k miles. After 100k miles you can throw the engine in a bin as a whole. A good normally aspirated Toyota/Lexus engine is good for 500k miles with nothing else than regular oil changes an a couple of spark plugs. If they ever put in the turbos on a Lexus it will be years after Toyota, as the first quirks need a couple years to be sorted out. Using turboed engines reduces reliability of every car. You can do the best engineering of the world, but a 700°C hot part rotating at 100k RPM will always be less reliable than just a piece of straight tube.
    • That is not true..A turbo engine have no problem with 30k miles, i have hade a Saab 9-3 2.0 turbo, and when i sold it it hade run 14.0000km without no problem, and i have never heard a Bmw owner say any problems with turbos..The new turbos with oil cooling dont have so much problems what i know..And i have never hear about a Toyota/Lexus that have 500k/miles or 800000km..And i hope that Toyota and Lexus get this turbo engines very soon, hopefully next year..qould be very nice with a CT and a IS turbo.
    • There have been tons of turbo engines that have proven very reliable over the years and decades. The famous Mercedes turbodiesels of the '80s come to mind, many of which ran well into the 300K mile region before the turbo needed an overhaul or replacement. A turbocharger is a device that simply needs to be replaced after time after wear and tear takes it toll. A prospective buyer needs to be aware of this. I think the performance turbo engines give turbo motors in general a bad name.Those engines have to endure enormous stress which also takes its toll on the turbo among other components meaning the engine will require more maintenance. But then again, any high performance car is high maintenance. Also, many people don't know how to treat their engines properly. I know people who get into their car to drive down the block to their local 7/11 and back home. This means their motor never gets a chance to reach its optimal operating temperature and that does affect the longevity of the motor in the long run. Turbo motors are even more sensitive in this regard.
    • Toyota has been making turbocharged engine for a very long time. There are turbocharged version of the Toyota counterparts. The Soarer (SC) had turbocharged 2.5L 1JZ-GTE and the Aristo (GS) has the 3.0L 2JZ-GTE turbocharged engine. They were never brought here because of our strict emission standards and is why we really don't see that many turbocharged engines in the late 90's early 00's. Turbo engine can reduces reliability of a car if you do crazy things with it. But all the turbo engines that Toyota has produced proves differently. It just shows that you can still have a reliability car even with a turbo on it. The 2JZ-GTE or any of the JZ block, along with the 7M-GTE (when propertly torque), are bulletproof engines. But with advancement in engine technology, turbocharged vehicle can make the same/more power than their bigger displacement counterparts while meeting the emission and fuel economy of their smaller displacement engine.
  9. They did make the Aristo with twinturbo
  10. This is good news.. It's funny because Toyota has been doing Forced Induction for a very long time.. It's just that they got so caught up with the U.S Market & the Toyota Camry that they kinda lost track with reality.. 
  11. onty 225hp !!!!!!  other companies achieved 400 hp 
  12. 225 hp out of a hybrid setup for gas mileage... not a max effort HP car...  I do not know of any mainline stock 2.5 turbo getting 400hp????
  13. When oh when is Lexus going to realise that in Europe at least they need a DIESEL !!!
  14. Oh - and dump the Hybrids !!
