It’s the second instalment of McLaren’s Ultimate Series, five years after the P1 rearranged our understanding of the natural world. Now it has a name – the McLaren Senna. Bold move, right, naming it after arguably the world’s greatest racing driver? But when you learn that Bruno Senna, Aryton’s nephew, has been involved in the development, and its mission statement is to be the company’s most focused and effective track car ever, it fits.
Unlike the P1, it is not a hybrid. You’ll find no battery ballast or e-motors here, just a development of the 720S’s 4.0-litre twin-turbo V8 wound up to 789bhp and producing 590lb ft of torque, channeled through McLaren’s trusty seven-speed twin-clutch ‘box. These are numbers that are no longer startling in the world of 1,400bhp+ hypercars, but when you combine that figure with the Senna’s obsessive focus on weight and downforce, its potency grows.
McLaren claims a dry weight of 1,198kg, 85kg less than the 720S despite packing 79bhp more. That’s 553bhp-per-tonne for the 720S versus 659bhp-per-tonne for the Senna – quite some leap.
Renault Megane RS
The new RenaultSport Megane launches with a number of headlines. First up, it has four-wheel steering as standard. No other hot hatch currently offers that, and it comes – whether you like it or not – with both of the Megane’s chassis options.
As always with fast Renaults, you’ve a choice of Sport (softer) or Cup (harder) suspension setups, the latter getting a proper differential on the front axle. That’s the one you want.
