therefore less restrictive – exhaust layout. Generating 585PS and 585Nm of torque, the all-new V6 engine is 190mm shorter and 220mm narrower than McLaren’s twin-turbo 4.0-litre V8 – and also 50kg lighter. While the configuration of the all-new engine is key to the Artura’s powertrain packaging, it is the innovative technology within that provides the biggest gains in lightweighting and performance. The cylinder head and block utilise 3D printed cores, allowing uncompromised precision cooling, including a micro-compact 2mm cooling passage between the cylinders. The block has directly coated parent bores rather than separate coated liners, into which fuel is injected at 350bar pressure. The Artura’s V6 engine is designed not just for compact packaging and efficiency, but also to increase driver engagement. Shared crank pins enable a very short and stiff crankshaft that allows the M630 to redline at a thrilling 8500rpm. It’s also a very refined engine, designed with the chain drive at the rear and with ancillary noises reduced so that the occupants only hear the V6’s distinctive intake and exhaust note, routed via Gasoline Particulate Filters to reduce emissions. The V6 engine powers the rear wheels via an all-new eight-speed seamless shift transmission that has also been design for optimised packaging. The length of the gear cluster has been reduced by 40mm, helped by use of a nested clutch rather than a parallel unit and also the removal of a reverse gear, this function now achieved by the Artura’s E-motor spinning in the opposite direction. The ultra-compact motor is fully integrated within the transmission bell-housing, delivering torque in-fill and linear acceleration via an E-differential to the rear wheels. The Axial Flux design of the E-motor is another Artura benchmark. It is similar in size to a McLaren brake disc and at just 15.4kg it is only a little heavier than a conventional iron rotor component, yet it can generate up to 95PS and 225Nm as well as enable journeys of up to 30 kilometres in near-silent pure EV mode, attributes that are ideal for city driving or early- morning starts. Providing the electric-only capability is a 7.4kWh Five-module Lithium Ion energy dense battery pack. Fully integrated into the Artura’s McLaren Lightweight Architecture (MCLA) chassis, the battery pack is positioned low-down in the car behind the driver, incorporated into the floor and protected on three sides by the main carbon fibre structure and from behind by the engine. This positioning also helps to optimise both centre of gravity and the polar moment of inertia, benefitting dynamic agility. 348 | Simply Abu Dhabi
