Although it’s worth noting that deliciously elongated aesthetics aren’t disappearing all together, as evidenced by the recently revealed McLaren Speedtail hypercar. But back to the 600LT. It takes the 570S engine as a start point. Its 3.8-litre twin turbo V8 increases power output to 600PS (or 592hp/441kW to us antipodeans). Torque is a meaty 620Nm @ 5500rpm. On paper, not jaw-dropping, but combine with McLaren’s fastidious attention to “adding lightness” and they are suitably amplified in practice. The 600LT is 100kg lighter than the 570S. And remember, the 570S is no beefcake. It’s astonishing how they physically found that much weight to carve off. To add context to the weight reduction, McLaren’s Director of Engineering Design, Dan Parry-Williams is quick to suggest, “On a car like the 600LT, a weight saving of 100kg is more beneficial to performance than adding another 60PS [44kW]” The beautiful thing about making a car lighter is the snowball effect it has on other components. The more weight you lose in sprung mass, the less substantial the suspension and steering hardware needs to be to take the load, so fat can be trimmed exponentially. More extensive use of carbon-fibre body panels, sure; that’s an easy 7.5kg saving. But McLaren’s engineering boffins got progressively more obsessive from there. They’ve used lightweight suspension arms, hollowed-out the sway bars, removed the radio and sat nav, taken the most lightweight forged wheels they could find and machined further material out of them. They’ve utilised titanium wheel bolts and employed front and rear windscreens that are 3mm thinner than those
