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 new Type R set a Suzuka Circuit lap record.

Honda

The new Honda Civic somehow improves on the formula laid out by its numerous predecessors and does so with style, refinement, and value. The Civic Si built on that foundation with a potent turbocharged engine and solid handling, but Honda's not done with the Civic. The automaker just teased the new Civic Type R, and it set records at Japan's Suzuka Circuit during a recent testing session.

The All-New 2023 Type R Achieves Track Record at Suzukawww.youtube.com

The Type R lapped Suzuka Circuit in 2 minutes, 23.120 seconds, a record-breaking lap for a front-wheel drive car. The video features neat telemetry information on-screen during the lap as well, but the real excitement comes later when full specs are revealed.

Honda's been understandably mum on details on the new Type R's powertrain and performance numbers, but the car is expected to carry the same powertrain with its predecessor. The 300-horsepower turbocharged 2.0-liter four-cylinder engine made that car a force to be reckoned with, so the 2023 Civic Type R will likely continue carrying that torch.

Honda Civic Type RHonda will fully reveal the car this summer. Honda

Honda will reveal the car in all its glory this summer. As for pricing, the previous car started around $38,000, so the new model should be around there to start. That, of course, is before dealers mark it up and other lucky buyers snap them up for insane resale on an auction site.

The Emira will be Lotus' last gas-powered car.

Lotus

Automakers of all sizes and shapes are going electric, and tiny British automaker Lotus is no exception. Known for building small, impossibly lightweight cars with amazing handling, Lotus is rolling out one last fossil fuel-burning sports car before its world changes completely.

Lotus EmiraThe Emira will be available with a four- or six-cylinder engine. Lotus

Lotus says the Emira will be its last gas-powered vehicle before its shift to an all-electric lineup. The Emira is available with both a V6 and a twin-turbocharged inline four-cylinder - a version of the world's most powerful four-banger. Orders for the V6 model have far exceeded expectations, and the automaker notes that traffic to its website has grown considerably due to the car's popularity.

Lotus borrowed the engine from AMG, but the power numbers are different than the specs announced in 2019. At that time, Mercedes-AMG noted that the engine could produce up to 416 horsepower, but Lotus is only squeezing 360 ponies out of the inline-four. That said, Lotus' ability to build featherweight performance cars means that 360 horsepower will be plenty to motivate the Emira with enthusiasm. An eight-speed dual-clutch transmission is standard and brings paddle shifters to a Lotus for the first time.

A load of options are available for the car, including seven interior color options, six exterior colors, four options packages, and multiple wheel designs. Though some sports and luxury automakers hold the best options back to charge more, Lotus offers a surprising number of standard features, including 12-way power seats with memory, Apple CarPlay and Android Auto, a 10.25-inch touchscreen, and a 12.3-inch digital gauge cluster.

Reservations for the First Edition model open on April 8 for customers in the UK with deliveries starting later in 2022. The Emira First Edition starts at $85,900, while the entry-level four-cylinder model starts at around $79,000. Lotus says more specs and pricing details will be made available this summer.
