Throttle response is also oddly inconsistent, particularly in the most aggressive Sport S setting. It’s so quick on initial response that it can make it hard to apply power smoothly and in as precise a fashion as you want to with 471bhp under your toes. At least the brakes are impressively strong and easy to modulate precisely in hard use, which comes in handy as the RC F turns in best with a bit of trail-braking to dial out the subtle understeer into which it's inclined to wash. Otherwise, despite the fact that you're conscious of the RC F's bulk, it feels like a car that really relishes corners. Get the nose tucked in and, once you've got used to the throttle response, you can adjust your line easily on the throttle. Our car also came fitted with the optional torque-vectoring differential, which no doubt helped to give it an extra edge of balance.
Having said all that, there's no getting away from the fact that the RC F falls short of the intuitive-feeling, razor-sharp responses of the BMW M4. That's in part due to having less front-end grip and slightly stodgier body control, but the steering is also slightly disappointing. While well weighted in normal use, it doesn’t offer the sort of reassuring, consistent mid-corner bite that you want. Instead it feels very anodyne and doesn’t have anywhere near the directness you need to feel confident in really plundering the RC F’s endearingly extreme performance.
It comes as a pleasant surprise that the RC F has respectable ride comfort, even on our rucked-up roads. Sure, it feels brittle over sharp-edged bumps, and it's firm enough that some mid-corner ruts can have the ESP light flashing as the car skitters for traction (a common irritation in the Lexus’s rivals, too), but generally the Lexus rides with decent pliancy for a car of this nature. Add to this the fairly hushed low-rev refinement, and the RC F is just as happy on a sedate motorway mooch as it is in banzai use.
Even the interior is pretty good. The seats offer loads of bolster and lower-back support, and you can even get two people in the back provided they’re not long-legged or behind a very tall driver. The touch-sensitive pad that controls the high-set sat-nav screen is a pain to use, but otherwise the dash is virtually identical to that of the IS. It feels solidly put together and has a touch of style flair in the fancy, high-tech dials, and you get used to the quirks of its layout with time.
