[VIDEO] BMW i4 vs 70s e-fuel Rolls-Royce sustainability test

According to the industry, electric cars are the way of the future. However, there are significant concerns about the long-term viability of the energy many use to charge cars. Are electric cars really a better choice than other alternative fuels if the electricity people use to charge them is polluting? In this new video, Harry Metcalf digs the effect of emissions from a BMW i4 M50 and a historic Rolls-Royce running on e-fuel.

Metcalf chose the aforementioned BMW i4 M50, a 1970s Rolls-Royce Silver Ghost powered by Coryton Sustainable e-fuel and a Range Rover P400e plug-in hybrid for this test. He then tests their efficiency and environmental friendliness by estimating how much CO2 they release per kilometre.

The i4 M50 emits no CO2, but the electricity used to charge it comes from various CO2-emitting sources. Metcalf reveals that electric cars would be cleaner in other regions because where he lives the energy is largely dirty. But it’s still a fascinating test.

He then compares the operating costs based on electricity consumption per kilometre with the cost of e-fuel per kilometre. Coryton’s e-fuel is quite expensive, almost twice as expensive as conventional fuel. However, the company made it from recycled biomaterial from farming. So it is made from plant material, tree material and various other bio-organic materials that have already absorbed CO2 from the atmosphere. Therefore, the CO2+ released when e-fuel is burned is recycled. When you take the fuel out of the ground, you release new CO2 into the air and then burn the fuel, releasing even more, which exacerbates the problem.

While EVs produce no emissions, the production of EVs emits huge amounts of CO2 into the atmosphere. This means that, for the time being, EVs are not as environmentally friendly as they appear. But many people were already aware of that. It is exciting to see how efficient and ecological e-fuel is for older cars. This means that in the future people might be able to drive our classic guilt-free in the future.
