Lotus Imagines What A Futuristic Electric Le Mans Racer Would Look Like In 2030
Компания Lotus представила концептуальный электрический спорткар E-R9, основанный на технологиях гиперкара Evija. Проект настолько футуристичный, что вряд ли когда-либо увидит свет. Его основная идея — показать, какими будут машины для гонок на выносливость в 2030 году.

Обтекаемый электрокар создали в дочерней Lotus Engineering как технологическую витрину достижений в области электрификации и аэродинамики. Разработкой E-R9 занималась команда инженеров, в которую вошли Ричард Хилл, отвечающий как раз за аэродинамику, и Льисс Керр, технический директор Geely Group Motorsports International. Визуализировать машину взялись сотрудники центра дизайна Lotus под руководством Расселла Карра. Аббревиатура E-R в названии означает Endurance Racer, а цифра «9» отсылает к сконструированному Колином Чапменом Lotus Mark IX.

Часть технологий E-R9 заимствовал у двухдверки Evija. Спорткар приводят в движение четыре независимых электромотора, благодаря чему реализовано удавление вектором тяги, а источником тока служит батарея с продвинутой внутренней химий, которая к тому же поддерживает «горячую» замену. Среди других особенностей — меняющие форму кузовные панели, расположенные на дельтовидном профиле. Они адаптируются под характер движения и регулируют потоки воздуха (уменьшают сопротивление либо увеличивают прижим), причем как в ручном, так и автоматическом режиме.

Вертикальные плоскости на корме тоже выполняют важную функцию: на высоких скоростях они помогают машине менять направление, так как на них начинают действовать дополнительные аэродинамические силы. По задумке, все это будет выглядеть как полет на истребителе. Правда, испытать E-R9 можно будет не раньше 2030 года. Хотя велика вероятность, что он так и останется всего лишь фантазией.


– Design study reveals electric race car for 2030
– E-R9 is “partly driven like a car and partly flown like a fighter jet” – Richard Hill, chief aerodynamicist, Lotus
– Active aero package includes ‘morphing’ body panels and aerodynamic control surfaces
– EV powertrain with torque-vectoring from Lotus Evija further developed to be driver-adaptable on the move
– Name, year and colour scheme all carefully chosen in tribute to Lotus’ racing heritage

(Hethel, UK – 16 February 2021) – Today we’re unveiling the E-R9, a dramatic new design study for a next-generation pure electric endurance racer that could be on the starting grid of circuits around the world for the 2030 season.

Finished in striking black and gold – a clear nod to Lotus’ pioneering motorsport heritage that led to 13 Formula 1 championship titles – the EV features a sleek fighter jet-style canopy centrally mounted in a delta-wing upper body. Innovations include advanced active aerodynamics with ‘morphing’ body panels and vertically mounted control surfaces to assist with high-speed cornering.

The E-R9 has been developed by Lotus Engineering, the globally renowned consultancy division of the business which delivers projects for external clients. The car has been created as a technology showcase of its philosophy, capability and innovative spirit in the fields of advanced electrified powertrains and aerodynamics.

E-R stands for Endurance Racer, while 9 is the car’s competition number carefully chosen in tribute to Lotus’ racing past. It was in a Lotus Mark IX that the race team made its debut appearance at the Le Mans 24 Hours, with company founder Colin Chapman among the drivers competing. The year was 1955, meaning the E-R9 race car concept – if raced in 2030 – would be in celebration of the Mark IX’s 75th anniversary.

The E-R9 was developed by the engineering team of Richard Hill, chief aerodynamicist at Lotus, and Louis Kerr, principal platform engineer on the Lotus Evija pure electric hypercar as well as technical director, GT, Geely Group Motorsports International. Visually it was brought to life by the Lotus Design team, led by Russell Carr, Design Director for Lotus.

Richard Hill commented: “What we’ve tried to do is to push the boundaries of where we are technically today and extrapolate into the future. The Lotus E-R9 incorporates technologies which we fully expect to develop and be practical. Lotus has an amazing history of developing unique solutions, and we’ve done it many times in motorsport and with our road cars.”

Chief among the car’s aero innovations are its ‘morphing’ body panels. Located across the delta-wing profile, this adaptability – where active surfaces can change their shape and attitude to the air flow either at the press of a button by the driver or automatically according to performance sensor inputs – would deliver minimum drag on the straights and maximum downforce in the corners.

Vertical control surfaces at the rear would generate aerodynamic forces to help the car change direction, without the limitations of grip at the tyre contact patch. The result is a racer that’s partly driven like a car and partly flown like a fighter jet.

The Lotus E-R9 features an advanced electric drivetrain powering each wheel independently, a system enhanced with torque-vectoring. It builds on technology already integrated on the Lotus Evija pure electric hypercar, though for the E-R9 would be fully adjustable by the driver on the move.

Louis Kerr commented: “Battery energy density and power density are developing significantly year on year. Before 2030, we’ll have mixed cell chemistry batteries that give the best of both worlds, as well as the ability to ‘hot-swap’ batteries during pitstops.”

Further details and more images of the Lotus E-R9 can be found in the March issue of evo magazine. On sale from today, it includes a 32-page supplement dedicated to the past, present and exciting future stories of the Lotus Engineering consultancy.

From the pioneering work of Colin Chapman in the early 1950s, via countless projects which the team has worked on in the decades since – some never revealed before – it’s a fascinating glimpse into a business which has done more than most to shape the automotive industry today.
