McLaren Automotive has acquired rights to the Elva name for its new Ultimate Series roadster, the McLaren Elva. It is the brand’s first open-cockpit road car. The two-seater celebrates Bruce McLaren-designed 1960s McLaren-Elva sportscars that embody McLaren’s pioneering design and engineering principles. Just 399 cars are being offered for customer order.

It is the lightest road car ever from McLaren Automotive, with bespoke carbon fibre chassis and body, unique carbon fibre seats and sintered carbon ceramic brakes, according to the company. There is no roof, no windscreen and no side windows.

The car provides unparalleled driver engagement and ultimate driving enjoyment, with absence of roof, windscreen and windows ensuring incredibly immersive and enthralling experience. McLaren Active Air Management System (AAMS) is a world-first. It shelters occupants by manipulating air flow while retaining their connection to the elements

“McLaren continues to push the boundaries of supercar and hypercar development in pursuit of outstanding and unparalleled driving experiences for our customers and the McLaren Elva epitomises that pioneering spirit. The McLaren-Elva M1A and its successors are in many ways the true spiritual forerunners of today’s McLarens – superlight, mid-engined cars with the highest levels of performance and dynamic excellence. It’s fitting that the new McLaren Ultimate Series roadster – a uniquely modern car that delivers the ultimate connection between driver, car and the elements and with that new heights of driving pleasure on road or track – acknowledges our rich heritage with the Elva name,” Mike Flewitt, CEO, McLaren Automotive, said.

The appearance of the McLaren Elva is unique. The low nose and pronounced front fender peaks provide visual drama and at the same time enhance forward vision. Large, carbon fibre rear fenders flow from the front of the door to the rear deck, while the height of the twin rear buttresses is minimised by using a deployable roll-over protection system.

A fixed windscreen derivative of the car is also available for most markets as a factory option.

The AAMS channels air through the nose of the Elva to come out of the front clamshell at high velocity ahead of the occupants before being directed up over the cockpit to create a relative ‘bubble’ of calm. The system comprises a large central inlet situated above the splitter, a front clamshell outlet vent and a discreet carbon fibre deflector that raises and lowers vertically; when the AAMS is active, the deflector is deployed at the leading edge of the bonnet outlet, rising 150mm into the freestream to create a low-pressure zone at the vent.

The vented air is directed through a 130-degree radius, using a network of transverse and longitudinally mounted carbon fibre vanes across the bonnet outlet; distributing the airflow both in front of and along the side of the cabin further assists air management in the cabin environment. At urban speeds, when the level of airflow into the cabin means the AAMS is not needed, the system is inactive. As vehicle speed increases, the AAMS automatically deploys and remains active until speed reduces, at which point the deflector retracts. The system can also be button-deactivated by the driver.

In addition to housing the AAMS, the front clamshell features deep contours that guide air into a discreet duct in the leading edge of each carbon fibre door –the lightest that McLaren has ever created. This captured cooling air is then directed into the two rear-mounted, powertrain-cooling, high-temperature radiators (HTRs) located just ahead of the rear wheels. A second, lower duct that starts inside the front wheelarch also channels air through the bodyside to the HTRs, which are additionally fed through the visible main side intakes. Intakes on the rear of each buttress channel combustion air into exposed air filters under the tonneau, which feed the carbon fibre engine plenum.

“Our mission with the McLaren Elva was to create an open-cockpit, two-seat roadster that delivers the most elemental of driving experiences. Formula 1-inspired shrink-wrapped volumes create a technical sculpture that is as striking as it is remarkable, the exterior flowing into the interior in a stunning example of a new and unique McLaren ‘blurred boundaries’ design principle that has allowed us to seamlessly bring the outside in, to further enhance driver engagement while remaining true to our philosophy of making no compromises,” Rob Melville, design director, McLaren Automotive, said.

There is no clear demarcation between the exterior of the McLaren Elva and the interior. The uppermost sections of the carbon fibre doors simply curve over and flow down into the cabin, the light, stiff and strong composite material providing the perfect properties to form such enticing shapes and forms.

A spar of carbon fibre additionally sweeps down from between the buttresses and runs between the driver and passenger seats to support a central armrest and cradle the engine start button and the controls for drive, neutral and reverse functions. The seats themselves are of a bespoke design, with a new lightweight carbon fibre shell that not only supports the head, shoulder and back area of the occupants, but works seamlessly with the upper shape of the cabin.

Stowage space is offered beneath the rear tonneau. Crafted from carbon fibre, the curving single-piece panel is operated manually and secured with soft-close latches. Elegant and lightweight, it further reduces weight at one of the highest points of the McLaren Elva. The compartment under the tonneau has space for helmets and also houses the porthole-like panels that showcase the two visible air filters.

Customers can select a Gloss Visual Carbon Fibre Body, which exposes not only the carbon fibre body panels, but also the perfectly aligned twill of the composite material. This can be further enhanced with a range of colour tints. McLaren Special Operations can also develop a bespoke tint for the exterior or interior carbon fibre.

“The McLaren Elva is a true Ultimate roadster; it exists purely for the pleasure of driving, to deliver an enthralling and immersive experience born from the ultimate connection between the car, the driver and the elements. The lightest road car we’ve ever built at McLaren Automotive, the Elva is incredibly agile and ferociously fast, its 815PS twin-turbocharged V8 engine providing breathtaking performance that heightens every sense,” Andy Palmer, Vehicle Line director – Ultimate Series, McLaren Automotive, said.

The core of the McLaren Elva is – as with every McLaren road or race car since 1981 – a carbon fibre monocoque. This state-of-the-art ‘tub’ is strong and stiff, and its inherent properties mean an open-top roadster does not require any additional strengthening as would be the case with a vehicle built from aluminium or steel. Conversely, despite its rigidity, carbon fibre is also light, helping to reduce the overall vehicle weight.

Carbon fibre has been used extensively throughout the McLaren Elva. The entire body is carbon, and McLaren has pushed the limits of the material to not only create incredible sculpted forms, but to also reduce weight. Each door is constructed entirely of carbon fibre and features a single-hinge design, mounting to the vehicle just behind the front clamshell. The floor within the McLaren Elva is exposed carbon fibre, highlighting the weight saving throughout.

Carbon forms the core of the braking system which is the most advanced ever fitted to a McLaren road car. Each sintered carbon ceramic disc takes significantly longer to produce than a conventional carbon ceramic disc, but the resultant material is much stronger and has improved thermal conductivity. This allows the front brake discs in particular to be reduced in size, benefitting unsprung mass while still maintaining performance. Cooling requirements are lessened, reducing the brake ducting needed, which further reduces weight and improves aerodynamic efficiency.
