THE LOTUS EVIJA AERO STORY: "A FIGHTER JET IN A WORLD OF KITES". EXCLUSIVE Q&A WITH LOTUS’ CHIEF AERODYNAMICIST RICHARD HILL

    •    New airflow animation explains the Evija all-electric hypercar’s unique porosity and phenomenal downforce
    •    Highly experienced senior engineer with 30+ years at Lotus details philosophy of the Evija’s sophisticated aerodynamics

(Hethel, UK – 12 May 2020) – The unique porosity and phenomenal downforce of the Evija all-electric hypercar has been brought to life in a new animation from Lotus.

For the first time, Richard Hill, the highly experienced senior engineer who has guided this critical element of the 2,000 PS car’s design, details the philosophy of the Evija’s sophisticated aerodynamics.

Richard is chief aerodynamicist and has worked at Lotus for more than 30 years, supporting countless road and race car projects. When asked how the Evija compares to regular sports cars, he replied: “It’s like comparing a fighter jet to a child’s kite.’’

The full Q&A with Richard Hill is below:
-    What’s the overall philosophy behind the Evija’s aerodynamics? It’s about keeping the airflow low and flat at the front and guiding it through the body to emerge high at the rear. Put simply, it transforms the whole car into an inverted wing to produce that all-important dynamic downforce.

-    How would you compare the Evija’s aerodynamic performance to that of a regular sports car? It’s like comparing a fighter jet to a child’s kite.’’

-    Can you explain the car’s porosity in aerodynamic terms? Most cars have to punch a hole in the air, to get through using brute force, but the Evija is unique because of its porosity. The car literally ‘breathes’ the air. The front acts like a mouth; it ingests the air, sucks every kilogram of value from it – in this case, the downforce – then exhales it through that dramatic rear end.

-    What role does that deep front splitter play? It’s designed in three sections; the larger central area provides air to cool the battery pack – which is mid-mounted behind the two seats – while the air channeled through the two smaller outer sections cools the front e-axle. The splitter minimises the amount of air allowed under the vehicle, thus reducing drag and lift on the underbody. It also provides something for the difference in pressure between the upper and lower splitter surfaces to push down on, so generating downforce.’

-    Are the Venturi tunnels through the rear quarters part of the porosity? Yes, they feed the wake rearward to help cut drag. Think of it this way; without them the Evija would be like a parachute but with them it’s a butterfly net, and they make the car unique in the hypercar world.

-    What is the effect of the Evija’s active aerodynamics?The rear wing elevates from its resting position flush to the upper bodywork. It’s deployed into ‘clean’ air above the Evija, creating further downforce at the rear wheels. The car also has an F1-style Drag Reduction System (DRS), which is a horizontal plane mounted centrally at the rear, and deploying it make the car faster.

-          Lotus pioneered the full carbon fibre chassis in Formula 1, and the Evija is the first Lotus road car to use that technology. How has that helped to guide the aerodynamics? The chassis a single piece of moulded carbon fibre for exceptional strength, rigidity and safety. The underside is sculpted to force the airflow through the rear diffuser and into the Evija’s wake, causing an ‘upwash’ and the car’s phenomenal level of downforce.

-    The Evija is set to be the world’s lightest EV hypercar. Does weight affect aerodynamic performance? The car’s weight has no effect on overall aerodynamics. However, the lighter the car, the larger the percentage of overall grip is achieved through downforce and the lower the inertia of the car to change direction.

-    Can you confirm the drag coefficient and downforce figures for Evija? We will release that data later this year when final testing is complete.

Richard Hill’s full title is Chief Engineer of Aerodynamics and Thermal Management, and he has worked at the company’s Hethel HQ since 1986. His role involves collaborating with the exterior designers of all new Lotus vehicles, from the early concept phase of a programme through to testing pre-production prototypes.

The focus is always on developing the aerodynamic performance which ultimately helps produce the world-class dynamic characteristics for which Lotus is renowned. Richard also helps to ensure all vehicle cooling, cabin ventilation and thermal management systems work correctly.

As well as working on road and race cars, Richard was the brains behind the Lotus Type 108 and Type 110 – better known as the Lotus Sport track and road bikes ridden to glory in the 1990s by legendary British Olympic and Tour de France cyclist Chris Boardman. He has also been instrumental in the development of the new track bike developed by Lotus for British Cycling athletes who will compete in the rescheduled Tokyo Olympics.

    •    A new model of integrating connected vehicles, connected homes and connected customers is being developed
    •    New, flexible platform designed to power a future digital mobility lifestyle
    •    New global sustainability programme targets net-zero carbon across Lotus operations

(Hethel, UK – 11 May 2020) – Centrica plc, the parent company of British Gas, and British motor manufacturer Lotus are working together to develop a new model for electric vehicle ownership that fully integrates future mobility and energy.

By making the car an extension of the home, capable of storing electricity, minimising emissions and generating new income by providing services to the energy market, the companies aim to redefine the customer relationship with cars – one controlled by smart devices at home and on the move.

The energy company will also facilitate a sustainability program that leverages innovative, low carbon technologies, and helps mitigate the environmental impact of everything from manufacturing through to sales and the day-to-day activities of Lotus employees, helping meet Lotus’ carbon reduction aspirations.

The new partnership will help establish a new global charging and energy infrastructure for new products as part of Lotus’ journey to net-zero carbon following huge investment into the business since 2018.

Centrica Group CEO Chris O’Shea said: “We are committed to helping our customers and communities achieve net-zero and to do so, we must enable the change to electric vehicles. We have the technology, the skills and the scale to do this and our partnership with Lotus is another step in bringing our commitment to life.”

Lotus Cars CEO Phil Popham said: “Our journey to net-zero carbon is absolutely lock-in-step with the Vision80 strategy for Lotus – taking us to eighty years of the business in 2028.  By then we will have transformed Lotus into a truly global player in the high-performance high-technology sector with a new range of cars that remain true to our fundamental promise of always being ‘For The Drivers’.  The difference is the energy and infrastructure that will power and support these products in the future – this new partnership demonstrates the progress being made and the ambition of our vision.”

Carl Bayliss, Vice President of Centrica Innovations, said: “Owning an electric vehicle isn’t the same as owning an internal combustion engine car. We see a future where the customer, car and home are connected, enabling new services beyond charging the car, and new products and experiences replacing the unremarkable standard relationship with energy and the ownership of a car today.

“Lotus is the perfect partner as we embark on this, given the recognition and appeal of the brand globally and the fact that it is right at the beginning of its electrification journey.”

Uday Senapati, Executive Director, Corporate Strategy for Lotus, added: “Centrica brings a wealth of energy sector expertise to the table that will not only help us to determine the right course for our mobility strategy, but the hands-on capability to ensure that the right infrastructure is in place globally. The future of mobility is a huge opportunity for providing value-added services to the consumer and this platform will put Lotus at the forefront of that digital mobility ecosystem.

“We have set ambitious targets for decarbonising both our vehicles and our operations. Given the rate of change required and the importance of getting it right first time, the support of our strategic partner Centrica is going to be vital.”

Production of the all-electric Lotus Evija hypercar will start at the company’s famous Hethel, Norfolk HQ later in 2020 – marking the start of Lotus’ journey to electrifying its growing range of vehicles.

Beh...attizza.

[naviossab]

Drammatica l'animazione delle ruote nel 3D...ma come si fa nel 2020 ?

Direi più un "dimostratore tecnologico" per Geely group, che un auto per Lotus.

Attendiamo molto più impazientemente le nuove Eagle..

[iDrive]

Lo stile e così così, la tecnica e ok, la Vmax un po’ bassa per una hypercar.

La nuova Eagle sarebbe l’erede della Evora?

Quale sarebbe questo telaio? Quello di Evora riadattato ai nuovi modelli?

 

Ad ogni modo, questa per esser una hypercar da 2000 cv ha un design troppo scialbo e con un posteriore gin troppo (mal) caratterizzato, imho. 
Nulla a che vedere con la Battista, una delle più belle hyper disponibili sul mercato e diretta rivale per prezzo e prestazioni di questa Evija.
