Lexus to Build a Twin-Turbo 600-Horsepower LF-LC Coupe?

Lexus LF-LC 600 Horsepower

Motor Trend has the scoop on possible engines powering the new Lexus coupe based on the LF-LC concept:

Word on the Tokyo street is that there’s a Lexus LF-LC Coupe mule running around Japan packing a 600-hp twin-turbo version of the upcoming RC F’s 5.0-liter V-8. That power rating may be on the conservative side.

There still isn’t much [information], but our sources confirm the monstrous twin-turbo V-8 will be the SC F. There’s a potent hybrid LF-LC/SC H whose powertrain will probably be the fruits of the BMW joint project and make around 500 hp.

There will be a third engine, a base naturally aspirated V-8, that will produce a bit less power than the hybrid (450 hp) but get worse fuel economy.

That’s a narrow horsepower spread for a single car — while I hope that every detail is true, it’s a bit of a stretch considering only one of these engines is currently in production (the naturally aspirated V8 would be the RC F engine) and all are extremely high-performance. Also, is there no plan to offer the next-generation SC with a V6 engine?

Really though, let’s focus on the big news — how about this twin-turbo SC F with 600+ hp? It just so happens that Toyota Motorsports in Germany has already built a twin-turbo 5.0L V8 engine and installed it in an LS — the final numbers were more than 640 horsepower and a top speed of 200mph. Matches up well with the rumor and seems like a strong possibility.

(Huge rumors over the past couple days, it’s getting very exciting in Lexus land.)

  1. Don't STRAT playing with Lexus from NOW ON!! cause you're gonna be DONW right when you press PLAY!! :D
  2. Keep the good new coming buddy, even though I cannot buy these cars it's great to brag about what Lexus has in the pipeline. IS F, LS F,NX F,RC F, RX F, SC F, that should be the F ing lineup.
    • Of the six models you listed, only one (RC F) is real. One model doesn't even exist (SC), two others are based on platforms that can't handle the power (RX/Camry), (NX), not to mention the NX engine bay can't fit anything larger than the 2.0 I4. One would likely never make it to production due to single digit sales (LS F). Only the IS F has a shot at being real. So, let's not get carried away with the fairy dust and Lexus Kool-Aid here.
    • I agree with you regarding FWD-based F models and to a lesser degree, LS-F. Regarding the SC, that is patently false. Paying attention to all forms of Lexus related news, will tell you that in the last 2 months, the next SC design was frozen and based on the LF-LC styling. This actually came from a named Lexus executive. If Toyota decides to throw away development money by cancelling it, that's a different story. The IS-F and LS-F are likely givens. Prior to working for JLR, I saw absurd arguments regarding the return of an XJR. It happened just before I joined. Lexus and Jaguar will both become very powerful forces this decade in that regard.
  3. Definitely will be a one variant as the 63 AMG & 65 AMG the 65 AMG will be the 650 TMG twin turbo found in the LS 650 TMG 1000% sure that this 600 hp is variant from the same 5.0L 1000% sure that we will see the 650 hp twin turbo 5.0L
  4. Lexus is definitely upping theirs game right now!!!! They have established themselves over the years and now it's time to hit hard!!! The LFA was/is an example of their intent and a good "litmus test" for them, can't help but say I'm excited of the alleged developments!!
  5. Now this is news ! Tired of the NX lol
  6. Lexus must been as something higher then the Germans once again. Once upon the time, Lexus once owned them. it was the LS400, SC, GS, IS these old lexus's of the 90's you can still see them in many music videos of that decade because at that time you had made it pass the mercedes and bought a lexus
  7. I'd don't know. 600+hp is good and everything, but it seems so not-classy compared to the refinement of the hybrid powertrain. I think this futuristic chassis calls for a futuristic, new-generation hybrid powertrain. A biturbo v8 would be just too much barbarism for this car. Keep these archaic huge-ass petrol engines for racing and for the torque-brained german premiums.
    • IMHO this is the soft mentality that has kept Lexus in the back of the Germans even up till now. All they need is more "power" at this point to be taken really seriously, the Germans have been doing it for years; now its Lexus' turn. Save all that unnecessarily heavy hybrid crap for dedicated cars like priuses and NX's and such, not sports cars which need as much dynamic capability as possible from a nat aspirated high power engines. Built them Lexus now is not the time to start getting soft on us again, keep on executing!
    • Totally agree With you. Lexus should be all-hybrid.
    • Toyota/Lexus should be all hybrid, with high-performance models as F/TRD cars. In the middle there is no market, and Lexus is just in the middle.
    • The GS 450h is a high performing car in my book, and it's a hybrid. They should do high-performance cars but With focus on class-leading low emissions and fule consumption With the help of an improved hybrid-synergy-drive-system(which I hope they have been hard at work at!). Why not a high-performing plug-in hybrid?! That would be a world's first.
    • I agree that their hybrids are good but true performance people want the engine and that's why it's good to have these big engines. Why not have both a hybrid and a big engine and give the customer the options to have what they want. Then they match the Germans engine (or surpass it) and have a hybrid engine too.
    • Because it takes a lot of effort and Resources to be the best in every game there is. Development of V8-monster cars will without doubt take Resources away from Development of what could be the best and most efficient luxury cars anyone has to offer. I also dont think the Development COSTs of V8-monster cars is justifiable since the COSTs wont reproduce in sales-numbers. There is a very Limited market for true perormance-cars.
    • Thomas I like your point a lot and I obviously don't know what Lexus's budget is for development but I don't think there needs to be any worry about their hybrid division. They have been the best hybrid technology in the world and it doesn't look like that's going away at all. But with performance Lexus doesn't have that and they might need to spend above and beyond to show what they have. They are up against tough competition from the Germans and others and to get people to switch you might need to make an engine that sounds ridiculously overpowered. At least with the new engines they are coming up with they will be used in multiple cars. The LFA is amazing but using the engine in one car and losing money isn't a good business plan but if they can make money on the cars then why not go for it.
