Motor Trend Feature on the Lexus RC F


Motor Trend has more details on the Lexus RC F, starting with additional information on 5.0L V8 engine:

This engine shares only its basic cylinder block with that of the outgoing IS F sedan. The cylinder heads and all moving parts are completely new. Friction reductions allow the engine to rev 500 rpm faster than the IS F’s, to 7300 rpm. A switch to electric phasing on all four cams brings greater variability and precision, and lets the engine borrow the Prius’ more efficient Atkinson cycle operation during low-demand cruising conditions.

Drop the hammer, and those valves shut in time to give you the full 12.3:1 compression (up from 11.8:1) and 5.0 liters of furious power — 480 horses’ worth (up substantially from the IS F’s 416). A newly modified version of the current D4S direct-injection with secondary port injection helps make all this work.

While most publications are stating the engine will generate more than 450hp, Motor Trend has upped the ante, claiming the V8 will be upwards of 480hp. That’s a significant difference, and one that seems unlikely given the singular source of the information.

One disappointing detail in the Motor Trend article is not specific to the RC F, but has to do with the new Remote Touch touch interface:

Making its debut on the RC is a new infotainment controller that swaps the old haptic mouse for a haptic touchpad. You can’t write letters on it with your fingers like in an Audi, but as you swipe across it, the pad provides vibrations and feedback to ease menu selections.

That's not the first place I have seen 480 bhp mentioned and with official channels say well in excess of 450 it may well be true.

How ever much or little HP it will get, the 5.0l V8 is enough to be good news. The really only disappointing thing is the weight. It is a total let down. I don't get how it can be more heavy if the car is smaller than the IS, has a new engine as uses more CF. Even the C AMG with its 4.0l V8 Biturbo weighs under 1.700 kg (EU) (insider info). M4 weighs more than 1550 kg (EU). 250 kg difference between M4 and RC-F is just impossible to compensate without Turbo and Electronics (GT-R).

    4.0L V8 Biturbo? the current C63 has a 6.3L N/A V8. The upcoming C63 is to have a 5.5L Turbocharged V8. I don't know where the 4.0L Biturbo came from

    4.0l V8 Biturbo making above 480 PS in the C AMG, up to 520 PS in the SLC AMG. This engine are two 2.0l I4 (from the A/CLA/GLA 45 AMG) "put" together.

I think the exterior design of this has remained solidly good-looking from concept to production. Lexus continues its streak of "good-looking" designs. When you think of Lexus even 5 years ago what did people say? "Solid ride, quality, but boring to drive and bland to look at." I think Lexus has added to its collection of successful designs. Between the new GS, IS and now RC the Lexus entry into each segment is the most interesting design, and the most engaging to drive. And this is a real V8 car so it wont be any slouch (but I want better fuel economy so I'd be putting an F Sport package on an regular RC 250/350).

Getting a little ahead of ourselves but if the RCF is using the 5.0 V8, what will the GSF use......

    I reckon the GSF would get 5L V8 Twin Turbo

    Agreed. Thats the only way I see Lexus getting even MORE power from this engine... enough to get to around 550hp. Or just completely build a new motor which would be awesome.

The 2UR-GSE is a high tech beast.

The GS-F will get the same engine. I doubt they would develop two different V8 engines at the same time.
