5 rare known three-wheelers in concept
Car manufacturers have rarely tried to design a three-wheeler vehicle ever since the advent of cars. However, there is still someone willing to try tomatoes…
The Nobe 100 is an electric-powered concept vehicle in retro style, which can be traced back to an electric car project in Estonia. The design is reminiscent of those car styles in the 1950s. Thanks to the retro design, Nobe 100 is very hopeful to get succeed. Talking about driving technology, Nobe’s driving system is quite simple. Each of the three wheels are powered by a same small 15 kW in-wheel hub motor. It’s top speed would achieve 110 km/h, and cover a distance of 220 km when charging for two hours. In addition to an emission-free feature of the entire vehicle, reusable and eco-friendly materials will be used on Nobe 100's body. Nobe officially announced that it had received an investment of approximately 900,000 euros until mid-July 2018, and promised to put this car into mass production in 2020.
4 electric three-wheelers named Ovum were provided to Moscow traffic police during the 2018 World Cup by Kalashnikov Company. The car is equipped with a 15kw brushless DC motor, weighs light as 500 kg and covers at least 150 km. It’s worth mentioning that thanks to Ovum's modular design, the number of seats in the cabin can be adjusted to meet the demand of various urban services.
GENERAL MOTORS LEAN MACHINE
Lean Machine is a concept car developed by Frank Winchell at general Motors in the early 1980s. This is a true "lean" machine with only one seat, and the body can be tilted to a similar heeling angle as a motorcycle when turning. The first ever prototype was powered by a 15-horsepower twin-cylinder engine with a top speed of 80 mph. Soon after, GM produced another 38-horsepower engine, which took only 6.8 seconds to achieve 60 mph from 0.
Mercedes-Benz F 300 Life-Jet
Life-Jet was first exhibited at the 57th International Motor Show in Frankfurt in 1997. It is recognized as one of the most interesting and passionate concept cars ever made by Mercedes-Benz. Life-Jet's engine and transmission are both from the A-Class, also it’s equipped with an active tilt control system to improves passenger comfort during steering, which means passengers do not need to resist against centrifugal forces when cornering. In addition, a sophisticated electronic system calculates the exact tilt angle required in any given situation with vehicle speed, acceleration, steering angle and yaw, and then transmits the tilt command to the hydraulic cylinder on the front axle, hydraulic cylinder then push one of the two spring struts outward to produce the desired inclination, up to a maximum of 30 degrees.
In August 1983, electronic tycoon Clive Sinclair set up Sinclair Motors after selling Sinclair Research’s stock and raised £12 million in funds, then hired Lotus engineers to join the project. Two years later, Sinclair launched the C5, a light electric vehicle with a 12-volt small motor. The body of the car is injection molded from plastic and its production mode is similar to that of electronic products. After the debut at the London Motor Show, C5 was immediately controversial and its security was strongly questioned. On the other hand, the open-roof design of the model does not meet the weather conditions in the UK…
