Lexus to Offer Next-Generation LS with Four-Cylinder Turbo Engine?

Posted by Kevin on July 8th, 2015

According to Japanese magazine Mag-X, Lexus will release the next-generation LS with a 2.5L four-cylinder turbo engine — here’s a translation of the article from site member AndyL:

At the current stage, two engines are considered. V8 High Performance Turbo in F-Sport to compete with MB AMG. Displacement is less than 5.5l.

2.5l inline 4 “downsizing turbo” with 10-speed auto from Aisin. This transmission is both highly efficient and with high performance.

A Lexus LS 250t is not inconceivable — after all, BMW will offer their new 7-series as a 2.0L four-cylinder hybrid and Mercedes has S 300 Hybrid, which is powered by a four-cylinder twin-turbo hybrid engine.

(I’ve always thought the LS should have a range of engines, but would have expected a V6 option before a four-cylinder turbo. That said, a LS 250t would be built for China and similar markets with high taxes on high displacement engines.)

I agree. A 2.5L for an LS sounds awful. I guess the 7 series is going to be and I know they can a lot with turbo and super charged but I loved how the LS was only a V8. I wish it was more powerful as I'm sure most do but having that real V8 over the turbo was always something cool about the LS

And I was wishing for the 4GR-FSE 2.5L V6 Turbo. Well, for any skeptics, if the 2L Turbo in the NX is any indication, we need not worry about NVH since this is a silky smoooooth and quiet engine to redline. With extra sound-deadening on the LS, it can only be better.

A 4-cylinder turbo engine with hybrid, yes. Without hybrid? No! A hybrid setup will give the LS the refinement it needs at least during lighter loads, when the car runs only on electric motors, and that should satisfy buyers who don't care about performance.

I would expect a more fuel efficient offering for the LS which basically shadows BMW. I did not expect a drop to a 4 cylinder unless it was a hybrid. Turbos get their power from their rev count and that is against the LS mindset. A V6 twin turbo would be my guess for an alternative to a V8. The LS has fallen behind its competition in performance so a 5.0 with say 450HP would make sense. Whatever the power train layout if this rendering is the actual new shape I am delighted. It has the side upsweep of the LFA which was first shown in the IS. It has the simplicity of shape like a Bentley. It is definitely not your father's LS.....

Imo it'll only be the part of a new hybrid powertrain, but it's unlikely if you ask me. 1. LS is prestige. A 4 cylinder engine can be smooth but nothing compared to a V6 or a V8. 2. Hybrid powertrains rely heavily on "switching on and off" the petrol engine and starting and stopping this frequently doesn't play well with turbocharged engines. 3. It's becoming even more unlikely that they're about to build a turbocharged hybrid powertrain when you take into account that Toyota partnered with Mazda almost exclusively to get their Skyactive technology, which are among the finest, (if not the finest) naturally aspirated engines on the market today. Regarding both torque-power characteristics and fuel consumption. Creating a new generation hybrid powertrain with a petrol engine utilizing the latest from Mazda's Skyactive engines and Toyota's latest atkinson cycle researches would make a LOT more sense to me.

while I sincerely hope that Lexus LS will have base 4cly engine with 300hp, article saying that "two engines are considered", does not give me much hope that magazine has some real info... since by now, they already know range of engines for LS and it cant be just 4cly and V8 for LS-F (Not F-Sport as written in article).... especially for Japan, I even doubt there will be 4cly option, thats more likely for Russia and China/Asia.

May 2017 sounds right, after Detroit and New York Auto Shows. The IS came out mid-year in 2012. I'm not worried about them bringing the LSF before the end of 2018, either. The 4-banger is for foreign, not Western, markets. May work in Europe, but not the U.S. They sell enough hybrids to not have to worry about CAFE for this low-volume sedan. Not really interested in a 10-speed slushbox, unless they can find a way to make it electronic in nature. 8 speeds is really the functional limit that the LS set several years ago. Beyond that you really need a CVT, but CVTs can't handle the power, so I'd work on tougher CVTs, not more gears. It's good to get a timetable. I expect to see it at the 2017 Detroit International Auto Show, if not the 2016 Tokyo Auto Show BD
