And then there's the engine; a performance-tuned, 5.0-litre, V8 - hence all the cooling ducts and domed bonnet.
And then there's the engine; a performance-tuned, 5.0-litre, V8 - hence all the cooling ducts and domed bonnet. The engine and component specifics are too technical and intense to go into here, but I will skim some highlights off the top. For instance, although it is a large engine, it is all aluminium and therefore lighter; the camshafts are hollow and carry oil to the cylinder heads and, we are told, that the crankshaft journals are polished to a 'mirror-finish'. All we need to know is that the end result is a reduction in friction between the moving parts and a quiet engine, unless your foot on the drive-by-wire accelerator deems otherwise. Justifiably proud, Lexus claims that it is one of the most sophisticated V8 engines in the world.
A proposition one is bound to agree with, when you realise that the 0-62mph time of just 4.8 seconds is not hypothetical and the top speed, which is limited to 168mph, is easily achievable, given the right circumstances.
And the right circumstances for us lesser mortals, who don't have unfettered access to a test track, is any road heading out of town. For sure you have to play by the rules but even within these constraints, the Lexus IS-F shows its colours.
It invites you to come and play with 423PS, which peaks at 6,600rpm, just before the red line at 6,800rpm, and share in the fun of 505Nm of torque at 5,200rpm. Ninety per cent of that is available at 3,500rpm, and that's without the aid of a super- or turbocharger, although it does have a fancy, dual-air intake system to help with the breathing.
