What is it?
The LS600h is Lexus’s latest and undoubtedly greatest hybrid; it marries a 5.0-litre 388bhp V8 petrol engine with a 221bhp electric motor in what must be the most seamlessly integrated hybrid drivetrain yet created.
All in, the 600h packs 439bhp, and yet it pumps out just 219g/km of CO2; one gram below the far less powerful Mercedes S320 CDi. It’ll also do 0-62mph in 6.3sec and hit 155mph while returning an average 30.4mpg.
What’s it like?
At 60mph, the loudest noise in the LS600h isn’t the ticking of the clock. Neither is it the engine, road roar, or even wind noise.
No, the loudest noise comes from the electric fan of the air-conditioning unit, cooling the supremely comfortable soft leather seat upon which you are sitting. And even that’s hardly what you’d call loud.
But we already know that the LS is a supremely refined car; the V8-powered 460 offering a kind of hushed gentleman’s club luxury. So why bother with a hybrid version - after all, if you were really interested in saving the planet, would you really be wafting about in a massive luxury saloon?
