Lightyear is working on solar technologies that help increase the range of its vehicle
The automaker wants to achieve 450 miles (724 kilometers)
Testing in real world conditions showed a range of over 249 miles (400 kilometers)
Lightyear showed the results of the most recent tests of its Lightyear One solar-electric vehicle prototype.
The company aims to make this model one of the most efficient electric vehicles and the targeted range is 450 miles (724 kilometers).
The results of tests made in sub-optimal conditions show the company is getting closer to these goals. These tests were conducted at Bridgestone’s proving grounds in Italy in conditions that better reflect the environment in which the production version will be driven.
Indeed, the temperatures averaged just 10 degrees Celsius (50˚F), which is detrimental to the efficiency of the batteries. In addition, the speed at which the prototype was driving was raised from 85 km/h to a constant 130 km/h, a speed that is common on highways in Europe and some American States.
In these conditions, the Lightyear One managed to drive for over 400 kilometers (249 miles), which is 1.5 times more than comparable EVs according to the automaker.
The efficiency of the Lightyear One is also said to be one of the best among other electric vehicles on the market, with 141 Wh/km against an average of 211 Wh/km for the competition.
Interestingly, the long range of the vehicle is not achieved with a large battery but rather trough aerodynamics and the company’s solar technology. Indeed, the prototype is only equipped with a 60-kWh battery, smaller than most other EVs.
This could lead to advancements in the industry that would allow for smaller batteries in electric vehicles, something that many automakers are trying to achieve in order to make cars that are more fun to drive, cheaper and more ecofriendly.
