The All-Electric Lotus Evija Hypercar
Lotus Cars Limited, is a UK based automotive manufacturer, famed for its iconic sports cars and participation in Formula One. The automotive manufacturer has witnessed a number of changes to its ownership since the founding of Lotus Engineering Limited in 1952, by Colin Chapman and Colin Dare. The company is currently owned by the Chinese automotive manufacturer, Geely, headquartered in Hangzhou, Zhejiang province. Geely also owns the automotive brands Volvo Cars and Polestar. Previously, Lotus was owned by General Motors.
Lotus is not new to electric cars. The company has already introduced the Lotus Evija, the all-electric hypercar. The Lotus Eletre Hyper-SUV is the second battery-electric vehicle (BEV) from the manufacturer and its most advanced Lotus vehicle to date. The company has the following electric vehicles (EVs):
- The all-electric Lotus Evija
- All-electric Lotus Emeya Hyper-GT
- The all-electric Lotus Eletre Hyper-SUV
The all-electric Lotus Evija hypercar is the most powerful production road car in the world. Hypercars is a term used to describe high-performance supercars. Hypercars are unusual and limited edition vehicles.
The pure electric two-door coupé Lotus Evija hypercar can deliver up to 2,000 ps of power and 1,700 Nm torque. The four-wheel drive EV can reach 0-100 km/h in under 3 seconds, and 0-300 km/h in 9.1 seconds. The Lotus electric car has a top speed over 320 km/h. The EV has five driving modes: Range, City, Tour, Sport and Track.
The EV has four independently controlled high-power density electric motors (500 ps power per electric motor). The e-motors were developed along with Williams Advanced Engineering (WAE).
No, you cannot have it delivered to your home right away. Though the automotive manufacturer had announced deliveries would commence in 2020, it has, since then, been delayed. Deliveries are now expected in 2023. The EV is expected to be manufactured at Hethel, UK, which has been the home for Lotus since 1966. Lotus will manufacture only 130 units, as a tribute to Lotus Type Number 130. The EV was revealed in July 2019.
Originally codenamed the Type 130, the name Evija (pronounced ‘E-vi-ya’) is derived from Hebrew, and means ‘the first in existence’ or ‘the living one’. The Lotus Evija is also the first pure electric British hypercar and also the world’s lightest production EV hypercar. The Evija uses a one-piece ultra-lightweight carbon fibre monocoque chassis (1,680 kg). It also utilises the concept of ‘porosity’ to reduce weight and increase performance.
The Lotus electric car has a 90 kWh EV battery mounted centrally behind the passenger compartment. Part of the EV battery is visible from the rear glass screen. The automotive manufacturer claims an electric range up to 345 km (WLTP) on a fully charged battery. Of course, real-world electric range will be lower, impacted by a number of factors to include, driving profile and speed.
Lotus claims it has the developed the world’s fastest charging EV battery. The EV battery was also developed in collaboration with Williams Advanced Engineering (WAE). The EV is capable of DC charging up to 350 kW, enabling the EV battery to be charged from 10% to 80% in 12 minutes and to 100% in 18 minutes. Of course, the key is finding a DC charging station en-route, that can rapid charge up to 350 kW DC! The CCS2 charging port is located at the rear of the electric vehicle (EV).
Bottom-line, electric driving is good for the environment and the wallet!

Solar And EV Charging: An Overview
The benefits of renewable energy, in particular, solar and wind energy, is already well established across Europe, and in other parts of the world. With the increase in sales of electric vehicles (EVs) over the past three years, the advantages of using clean and renewable energy has been further enhanced.
Firstly, on-site renewable energy can be used for powering both business premises and homes. For on-site generation, we have witnessed a significant increase in distributed clean energy generating plants i.e. many commercial buildings and residential buildings have become generators i.e. generating electricity on-site! Solar roof projects have been popular for such on-site generation installations.
The ongoing war in Ukraine has further amplified the need to develop energy security, not only at a national level, but also at a local level, to include, businesses and households. Those households and businesses that already generate and consume clean energy on-site have been spared the significant onslaught of energy price rise in 2022, which is expected to continue in 2023.
Installing solar panels on-site, mitigates the risks associated with energy price inflation, a significant contributor to costs for a business or a household. On-site renewable energy generation also impacts the environment positively. For those with electric vehicles (EVs), in particular, pure electric vehicles, we strongly encourage the use of renewable energy for EV charging. Of course, we also encourage the use of solar energy for charging a plug-in hybrid electric vehicle (PHEV).
Apart from the significant cost benefit i.e. generating renewable energy is a nominal cost per kWh (after initial set-up/ installation costs), to achieve true zero-tailpipe emission electric driving, renewable energy needs to be used for EV charging. This is also known as ‘well-to-wheel’. Just one electric car on the road can save an average of 1.5 million grams of CO2.
The good news for electric car owners is that a number of EV charging stations are now compatible with solar/ wind generation and battery storage. The UK manufacturer myenergi zappi is a good example of a solar/ wind compatible EV charger.
We encourage business and households to adopt an on-site ecosystem of ‘renewable energy-battery storage-EV charging’, to gain the maximum from the advantages of low carbon generation and zero-emission electric driving. Bottom-line, renewable energy is good for the environment and the wallet!
