Imagine an entirely flat and modular platform in which the motor, steering, suspension, drivetrain, sensing, brakes, thermal systems, and electronics are all integrated into the vehicle’s wheels. All components previously found under the hood of the car would now be incorporated into the vehicle base, and the inner wheel space would contain electric motors and a miniature gearbox, with this revolutionary design.
Cars have come a long way since they first emerged at the dawn of the 20th century. The first “modern motorcar” was the 1901 Mercedes, which could reach a peak speed of 53 miles (85 km/h) per hour. In 1908, American automaker Ford introduced the Ford Model T, the first affordable automobile credited with revolutionizing modern transportation.
The automobile granted individuals greater independence and mobility and spurred the growth of outdoor recreation, tourism, and construction. Although car ownership is virtually universal in the developed world today, the automotive industry is anything but static – autonomous vehicles, electric and hybrid cars, electrification of infrastructure, connected cars, and shared transport are all megatrends now remaking the auto industry.
Israel is a leading player in the transforming auto industry, with some 500 startups and companies in the auto tech arena. These companies’ efforts range from detecting sleepy drivers to creating digital cockpits, developing electrified infrastructure that can charge electric vehicles while in full motion over smart roads, intelligent transport systems, vehicle cybersecurity, and satellite navigation technologies.
Tel Aviv-based company REE has emerged from stealth mode this month after six years of development to introduce its unprecedented approach to vehicle design and functions, specifically for the electric vehicle (EV) market. This market, which includes both hybrid and electric battery-operated vehicles, is especially promising but still relatively small with just over two million units sold in 2018. The two main challenges it faces are cost and logistics. Battery packs are cumbersome and expensive, even as costs are falling, and charging infrastructure requires major investment.
REE sought to flip the script on these gaps and developed an entirely flat and modular platform in which the motor, steering, suspension, drivetrain, sensing, brakes, thermal systems, and electronics are all integrated into the vehicle’s wheels. All components previously found under the hood of the car would now be incorporated into the vehicle base, and the inner wheel space would contain electric motors and a miniature gearbox, with REE’s design.
The goal, REE said in a statement this month, was to “fundamentally change[s] the way electric vehicles are built to power widespread vehicle electrification.”
This design is a crucial addition to the electric and autonomous vehicle revolution and can be adapted to the use of SUVs, trucks and personal and shared vehicle models.
REE says the design’s low center of gravity maximizes efficiency and supports agility and stability and the integrated wheel offers manufacturers freedom for body configurations. The flat platform would reduce the weight of the vehicle by 33 percent, allowing for a higher load per ride while also freeing up space by 67 percent, reducing costs and increasing efficiency, according to the company.
REE co-founder and CEO Daniel Barel told Interesting Engineering in an exclusive interview this month ahead of the launch that “the single biggest expenditure for an OEM [original equipment manufacturer] auto manufacturer is the platform…it costs billions, it takes years, and each OEM has between two and six platforms at any given moment, and two or three in development. We went in and said ‘what if you might need only one? That might be worth something.”
