Artura is McLarens first V6 hybrid

The all-new McLaren Artura is revealed today, marking the beginning of both a new chapter for the pioneering luxury supercar company and a new era in supercar technology and performance.

McLaren’s first series-production High-Performance Hybrid supercar focuses more than half a century of the company’s racing and road-car experience and expertise into a next-generation supercar that blends ground-breaking technology with McLaren’s dedication to pure driver engagement.

Underpinned by the McLaren philosophy of super-lightweight engineering, the all-new Artura is the distillation of every attribute inherent in a McLaren – distinctive design, unrivalled performance, dynamic excellence and engineering innovation – with electrification now bringing the additional benefits of even faster throttle response, lower emissions and being able to run in pure EV mode for emissions-free journeys of up to 30km

All-new from the ground up, the Artura presented McLaren engineers and designers with new opportunities to innovate, chief among these being how to preserve McLaren’s super-lightweight engineering philosophy when adding hybrid powertrain elements including an E-motor and battery pack.

A demanding programme of weight reduction, encompassing every area of the Artura from the chassis platform – this is the debut of the new McLaren Carbon Lightweight Architecture (MCLA) – through the uniquely compact HPH powertrain system to the weight of cabling used in the electrical systems (where a 10% reduction was achieved), resulted in the Artura having a lightest dry weight of 1,395kg*. The total weight of hybrid components is just 130kg (which includes an 88kg battery pack and 15.4kg E-motor), resulting in a DIN kerbweight of 1,498kg which is on par with comparable supercars that do not have hybrid powertrains, giving the Artura a super-lightweight advantage.

At the heart of the Artura’s powertrain is McLaren’s all-new, 2,993cc twin-turbocharged V6 petrol engine. With a power output of 585PS – nearly 200 PS per litre – and 585Nm of torque, the dry-sump aluminium engine is compact and lightweight; at just 160kg it weighs 50kg less than a McLaren V8 and is significantly shorter, enhancing packaging efficiency.

Designed to run with a Gasoline Particulate Filter to optimise emissions performance, the M630 engine is also extremely refined. The 120° v-angle of the engine, which allows the turbochargers to be positioned within the ‘hot vee’, delivers further advantages in packaging as well as contributing to a lower centre of gravity. The 120° layout increases engine performance by reducing the pressure losses through the exhaust system and allows for a stiffer crankshaft that enables a rev limit of 8,500rpm, maximising performance and driver engagement.

Working in harmony with the new V6 is the Artura’s compact axial flux E-motor, located within the transmission bell housing. Smaller and more power-dense than a conventional radial flux E-motor, it is capable of generating 95PS and 225Nm and boasts a power density per kilo 33% greater than the system used in the McLaren P1™. The instantaneous nature of the motor’s torque delivery – known as ‘torque infill’ – is key to the car’s razor-sharp throttle response. Exhilarating ‘off-the-line’ performance sees the Artura achieve 0-100km/h (0-62mph) in just 3.0 seconds*, with 0-200km/h (0-124mph) taking 8.3 seconds* and 0-300km/h (0-186mph) 21.5 seconds*. Top speed is limited to 330km/h (205mph).

The dual propulsion systems are integrated via an engine disconnect clutch, driving an all-new, twin-clutch transmission, which has been developed specifically for the Artura. Despite having one more ratio than the existing McLaren transmission – to optimise power and torque delivery – the lightweight, short-ratio gear cluster is 40mm shorter in length. It also requires no reverse gear – the E-motor takes care of reversing by literally rotating in the opposite direction.

Inside, the Artura is no less of a revolution, with the cockpit centred more than ever around the driver. The driving mode selection – which retains separate Powertrain and Handling controls – has been moved to the instrument binnacle, which is in turn mounted to the steering column and adjusts with the steering wheel to further enhance driving ergonomics. Consequently, the steering wheel is kept clear of unnecessary switches, however, the driver is still able to adjust driving modes without taking their hands away from the wheel.

Available to order now from McLaren retailers, with first deliveries to customers commencing in Q3 of this year, the Artura is priced in its home UK market from £185,500 for the standard specification. There are three further core specifications: Performance, which has a sporting, functional aesthetic; TechLux, where the focus is on the technical luxury that the name suggests; and Vision, which displays a more avant-garde and adventurous look and feel.
