In an extraordinary fusion of cutting-edge technology and automotive heritage, McLaren has introduced the W1, a ground-breaking successor to its legendary F1 and P1 models.

This latest addition to the McLaren ‘1’ lineage sets an unprecedented standard in the world of supercars, pushing the limits of both design and engineering.

At the heart of the W1 is an all-new V8 hybrid powertrain, delivering an astonishing 1275PS. This makes it the most powerful McLaren ever produced – outperforming even its fiercest rivals in the hypercar arena, the marque proudly claims.

The new W1 has been created according to the McLaren ethos of class-leading performance, informed by the core principles that underpin every McLaren supercar: epic power applied through cutting-edge aerodynamics and lightweight chassis technologies; the highest levels of dynamic excellence and the purest driver connection; the perfect driver environment, for all driving situations; and awe-inspiring visual and aural drama.

All of McLaren’s significant and renowned expertise in lightweight engineering and aerodynamic performance – inspired by years of racing innovation and the company’s World Championship mindset – was applied to W1. The engineering team behind the new McLaren Ultimate model have between them contributed to 16 McLaren Formula 1 World Championship titles across driver and constructor categories. This expertise, as part of a bigger team, has resulted in the most focused supercar that McLaren has ever built, but also one with a huge breadth of capability.

W1 is a supercar for all occasions; more than any other McLaren, it is equally at home on road and track and as the fastest-lapping and fastest accelerating McLaren road-legal supercar yet, is exhilarating to drive whatever the circumstances.

At the heart of W1 is an all-new high-performance hybrid powertrain, comprising McLaren’s all-new MHP-8 V8 combustion engine, an all-new E-module (integrating a radial flux electric motor and motor control unit), and an 8-speed transmission with E-reverse. Power and torque are to the rear wheels only, through an E-differential.

The 928PS of the new V8 and 347PS of the E-module combine to produce 1275PS, giving W1 the highest-ever power output of any McLaren and putting it above all core competitors. Engineered for epic power delivery and breathtaking performance, the powertrain combines with a vehicle weight of 1,399kg to deliver an astonishing power-to-weight ratio of 911PS/tonne for W1 – the highest-ever for any road-legal McLaren and more importantly, best-in-class.

McLaren’s philosophy of Lightweight Engineering and the use of bespoke carbon-fibre structures deliver a vehicle lightest dry weight of just 1,399kg for W1, which is key to the requirement for outstanding performance, everywhere – whether on road or on track.

The new W1 is the fastest-accelerating and fastest-lapping road-legal McLaren ever, achieving the astonishing combination of being quicker than a Speedtail to 300km/h (186mph) in a straight-line and 3 seconds a lap ahead of a McLaren Senna on McLaren’s reference track.

It offers an incredible acceleration of 0-200km/h (0-124mph) in 5.8 seconds and 0-300km/h (0-186mph) in less than 12.7 seconds with maximum speed electronically limited to 350km/h.

The supercar maker will produce just 399 customer cars – and it says all have already been customer allocated.
