Also playing in this Sport+ car’s dynamic favour are the carbonfibre roof (which replaces the standard cars panoramic roof in this and Sport trim) and other key enhancements that are wrapped up under the ‘Lexus Dynamic Handling’ banner, namely a variably geared steering unit that weights up according to speed, rear-wheel steering that aids turn-in and a limited-slip diff that works with the driver aids to keep everything in line.
The result is really rather delicious at pace. This, remember, is a front-engined, rear-drive 2+2 with GT pretensions; it is set-up to understeer but only does so if you really make a hash of things. In normal, fast road driving, there is a delicacy to the steering that’s quite addictive. Aided by the rear wheel movement, there’s a confidence-inspiring sense that the back of the car is moving not only in co-ordination with the front but also to its benefit, which is quite refreshing if you’ve spent time in big-engined German rivals that resolutely let the front end do all the work.
There’s abundant grip and the suspension and diff can handle odd cambers, big, mid-corner bumps and seemingly optimistic throttle applications with remarkable composure, gathering everything up and slinging you on. What is a firm ride at low speed becomes more supple at pace. It brakes quickly and confidently, too, even when you stand on the pedal, and it's just wonderfully easy to find a rhythm. The LC feels alive in a way no Lexus bar the LFA has before. Comparisons with the aforementioned 911 might be over-egging it, but as a BMW 650i or Merc SL rival it has a claim to bragging rights.
That the chassis is able to eclipse the powertrain should tell you a lot, because - shock - the 5.0-litre V8, a modified version of the unit found in the RC F and GS F, is no shrinking violet. Producing 467bhp at 7100rpm and 389lb ft at 4800rpm, itis predictably punchy but, for all its hairy-chested shove, it doesn’t dominate. In anything below Sport S mode (the penultimate of six settings) it propels you along quickly but with a soundtrack that’s louder than the engine response is fast. Dial it up, though, and everything becomes crisper and progress more instant; Sport is ideal for a favourite road, offering a beguilingly immediate response, with Sport S +, when everything dials up or off, best left for the track.
The secret - or perhaps surprising - weapon in its armoury is a new, 10-speed direct-shift gearbox. On paper, it sounds like a nightmare that will leave the auto-shift sensors scrabbling around wondering where to go. In reality, it changes swiftly and decisively and does a great job of keeping the engine in its sweet spot between 4000 and 5500rpm when you’re licking on. Crucially, it’s the first six gears - and chiefly third to sixth - that do most of the work, the additional ratios only playing for the benefit of refinement and economy at consistent cruising speeds.
