The McLaren W1 has been unveiled because the British supercar producer’s newest halo product, the newest in a lineage of ‘1’ fashions comprised of the naturally aspirated F1 and the turbocharged, hybrid P1. The W1 arrives with an all-new 4.0 litre twin-turbo V8 engine, elevated concentrate on aerodynamics and a brand new Aerocell monocoque.
As progress dictates, the W1 comes with powertrain that has been uprated over its P1 predecessor, packing 1,275 PS and 1,340 Nm of torque in mixed outputs from its hybrid powertrain. The ICE a part of the equation is an all-new MHP-8 4.0 litre, flat-plant crank twin-turbo V8 engine that displaces 3,988 cc, producing 928 PS and 900 Nm of torque.
Building of recent engine makes use of aluminium in its block, cylinder heads and pistons, employs plasma-coated cylinder bores, and options each direct- and port-injection. Cylinder dimensions are oversquare, with bore and stroke of 92 mm and 75 mm, respectively, and the dry-sumped MHP-8 engine is redlined at 9,200 rpm.
The exhaust options tubular manifolds with equal-length runners tuned to ‘construct sound to a crescendo’, feeding a pair of twin-scroll turbochargers that are optimised for larger peak energy and considerably extra torque all through the engine pace vary in comparison with the model’s current M840T sequence of engines, which powers the 825 PS Senna GTR.
Electrical drive within the W1 is by a motorsport-derived E-module that contributes as much as 347 PS to the automotive’s mixed outputs, and this module consists of a radial flux motor that spins as much as 24,000 rpm with a selected output of 23 PS per kg.
That is mixed with an built-in silicon-carbide motor management unit, and the entire electrical drive unit weighs simply 20 kg, says McLaren. The drive motor is fed by a 1.384 kWh battery that options di-electric immersion cooling for elevated cooling when the automotive is subjected to sustained observe operating.
The battery, administration unit and energy distribution unit are enclosed inside a fireproof cowl and mounted inside a cavity constructed into the automotive’s carbon-fibre monocoque, situated low within the automotive to learn centre of gravity and away from potential influence from the engine, transmission and rear construction.
Its battery cells are designed to prioritise excessive energy outputs as a way to enhance throttle response and increase general energy, and the battery’s state of cost is managed as a way to keep a minimal degree to be adequate for beginning the engine, provide energy for reversing and as a reserve. The full weight of hybrid elements have been lowered by 40 kg in comparison with the P1, says Mclaren.
Mixed outputs, paired with a weight of 1,399 kg, the McLaren W1 attains a power-to-weight ratio of 911 PS per tonne, which is the very best but of any road-legal automotive from Mclaren, it says. The hybrid powertrain sends drive via an all-new eight-speed DCT gearbox and e-differential, powering the rear wheels completely.
For acceleration, 0-100 km/h is finished in 2.7 seconds, 0-200 km/h in 5.8 seconds and 0-300 km/h in below 12.7 seconds, or simply below the 12.8 seconds required by the highest speed-focused Speedtail. In the meantime, high pace for the W1 is electronically restricted to 350 km/h.
Forming the spine of the McLaren W1 is the producer’s all-new Aerocell carbon-fibre monocoque, constructed utilizing pre-impregnated, or pre-preg carbon-fibre as used within the track-only Solus GT. The simplified curing course of brings larger structural energy and permits for a lighter construction.
Use of the brand new Aerocell monocoque additionally brings the brand new anhedral door association, succeeding the dihedral door structure of current McLaren fashions. This brings aerodynamic advantages in addition to bettering entry and egress from automotive, the latter aided by the offsetting of the A-pillars the place they meet the chassis and thus releasing up extra space for entering into the footwell.
Aerodynamic advantages of the anhedral door structure come from optimised airflow from the entrance wheelarches in direction of the radiators, enabling an additional 100 mm of cooling house which permits using smaller radiators for cooling the powertrain, says McLaren.
On the again, a structural diffuser product of intermediate-modulus carbon-fibre serves as each an aerodynamic part and a structural load-bearing half, enabling additional weight saving because the diffuser’s energy and stiffness does away with the automotive’s want for a cross-car construction becoming a member of the suspension pick-up factors, whereas permitting important diffuser quantity. The rear diffuser additionally serves as a crash construction, or rear bumper.
An included Race mode deploys the energetic entrance and rear wings whereas decreasing the automotive by 37 mm in entrance and 17 mm on the rear, providing as much as 1,000 kg of downforce (350 kg entrance, 650 kg rear) at 280 km/h.
Extra direct inspiration from Method 1 comes within the type of suspension pushrods with inboard dampers, which mix with wishbones, torsion bars and heave dampers to type the the W1’s entrance suspension structure. This idea is employed to optimise aero effectivity by serving to keep a clean stream of air, whereas the rear suspension structure employs conventional outboard springs and dampers, the place airflow is much less important.
For braking, the W1 makes use of the McLaren Carbon Ceramic Racing+ (MCCR+) setup that brings 390 mm discs clamped by six-piston calipers in entrance and four-piston calipers on the rear. Tyres measure 265/35R19 in entrance and 335/30R20 on the rear, with the Pirelli P Zero Trofeo RS road-legal track-day tyre as commonplace fitment, bespoke to the W1. Different choices are the P Zero R and P Zero Winter 2 for highway and winter use, respectively.
Cabin lodging are for 2 within the W1, and this has additionally been dictated by the brand new Aerocell construction. With a view to minimise the size of the Aerocell and thus the automotive general, seating is mounted and included into the monocoque, whereas the pedals, steering and different major controls transfer to fulfill the driving force. Baggage is by a stowage shelf behind the seats, holding 117 litres.
Smartphone connectivity is by Apple CarPlay through USB-C, accessed via an eight-inch McLaren Infotainment System (MIS II) touchscreen, whereas USB-A supplies machine charging and knowledge storage entry; audio is by a bespoke Bowers & Wilkins system.
Final however not least, the value. Autocar reviews that transacted sums are anticipated to be in extra of two million kilos sterling (RM11.2 million) because of the customisation choices on supply, and all 399 examples of the W1 manufacturing run have been spoken for.
