Comparing the Lotus Evija to other cars is 'like comparing a fighter jet to a child's kite'

It's sleek and sophisticated. It's also slippery. The Lotus Evija is the first-ever British all-electric hypercar, and it's here to make a statement.

That statement, in large part, is thanks to the car's sophisticated aerodynamics. Richard Hill is a senior engineer with 30 years of experience the brand working on everything from road cars to race cars. As the Chief Engineer of Aerodynamics and Thermal Management at Lotus, he is responsible for making the Evija as slippery as possible.

During a recent interview, Hill shared the vision behind the sleek Evija's design and compared it to the competition.

The overall philosophy in designing the Evija was to do what happens with most new cars, especially supercars, "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."

That downforce and the car's technical details are extraordinary says Hill. When asked how the Evija compares to regular sports cars, he replied: "It's like comparing a fighter jet to a child's kite.'' He went further, "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."

McLaren designed Evija's splitter into three sections. The large central area provides cool air to the battery pack, which is mounted at the car's midpoint, similar to where Audi keep the V12 in its R8. The splitter minimizes the amount of air allowed under the vehicle, which reduces drag, making the car more aerodynamic. It also works to generate downforce.

At the back of the car are Venturi tunnels. Named for Giovanni Battista Venturi, an Italian physicist who first published on them in 1797, Venturi tunnels on the Evija work to reduce the pressure on the car and cut drag. Hill says, "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."

To make the car stick even more to the road, there's a rear wing. It gets deployed into the "clean air" above the car helping the rear wheels stay planted. Lotus has also equipped the car with an F1-style Drag Reduction System, which is a horizontal plane mounted centrally at the rear. This helps the car achieve higher speeds, quicker.

Even the car's chassis plays a part. "The chassis a single piece of moulded carbon fibre for exceptional strength, rigidity and safety," said Hill. "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."

Official coefficient of drag and speed numbers are forthcoming. The model is projected to achieve over 200 mph.

The car incorporates modern and future Lexus design.

Lexus is putting the pedal down. The company is working to accelerate the production of new models as its moves to diversify its lineup. Currently the brand offers five sedans, eight SUVs, and five coupes, with slightly less than half of those being hybrid variations of other vehicles on the roster.

By 2025, the luxury arm of Toyota will introduce 20 new or improved models, including more than 10 electrified models including battery electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs), hybrid electric vehicles (HEVs), and other electric vehicles. The company is also is committed to making sportier versions of their more traditional vehicles.

Lexus aims to be a carbon neutral company throughout the lifecycle of its entire model lineup by 2050. To help achieve that goal, in March 2024 Lexus will open a new business and technical center that will allow various Lexus teams to more cohesively work together.

The LF-Z Electrified concept car is a conceptual BEV that puts driving performance, styling, and technology today in one concept car package. The exterior of the mode furthers the Lexus design story, carrying with it many hallmarks of today's vehicle design while infusing new elements. Lines are clean, simple, and directional, drawing the eye forward and back toward simplified design at the face and rear.

It is driven via all four wheels, a technology called Direct4. Lexus says that the system has many advantages, "By controlling the front and rear drive wheels independently, the system can provide the appropriate drive system ...for each driving situation. The system controls the distribution of driving force through the seamless orchestration and calculation of accelerator pedal application and steering wheel operation, resulting in powerful acceleration and exhilarating cornering performance that aligns near-perfectly to the driver's will."

Engineers have given the car the "Lexus Driving Signature", a connected drive experience that made its debut in the refreshed 2021 Lexus IS. This new model is said to raise that driving style to new heights by "evolving the basic performance of the vehicle".

The BEV hides its battery longitudinally under the floor of the vehicle, attaching it to the chassis and adding rigidity. This, in addition to other design attributes is said to help mitigate vibrations and noises that tens to permeate the cabin.

Lexus designers have created the cockpit with open and minimalist design. Engineers have given the car futuristic tech that interacts with the driver by learning their behavioral traits and patterns. When it does that, the car's infotainment system will be able to offer proposed routes and other lifestyle choices. Mercedes-Benz's infotainment technology already does this.

A panoramic glass roof and simple, molded forms emphasize the car's connection with its environment, according to the automaker. Look closely at it all. Lexus says the design shown here suggests the direction of next-gen Lexus interior styling.

This concept includes numerous technologies already applied in luxury and mass market vehicles, including digital key, which allows phone-as-key technology and makes delivering packages to a vehicle easier. An E-Latch system extends and retracts door handles depending on when they are needed.

Reclining and massaging seats, a next-generation Mark Levinson audio system, and other features complete the Lexus concept car package.
