In the last week, three hugely important things transpired to signal a seismic shift towards electric cars, and much sooner than many experts predicted.

On Friday last week, Tesla delivered the first batch of its long-awaited, affordable, pure electric Model 3 cars to customers in the U.S. Meanwhile, in Germany, the 2017 Le Mans winner Porsche was announcing its decision to leave the world of fossil fuel-powered World Endurance Championship – including the ‘Le Mans 24-Hours’ – in favour of the all-electric Formula E series.

With its new mass-marketed model finally landing in showrooms, Tesla will be offering the Model 3 at prices starting from $35,000 for a car with a 220-mile range. Or you can go for the 310-mile version for $44,000. Finally reaching its goal of offering a reasonably priced EV to the masses, the only problem Tesla faces is meeting its self-inflicted aggressive production schedule of 400,000 units by the end of 2018.

Adding a kick in the pants to future gasoline and diesel powered racing on the previous Monday, Mercedes Benz confirmed its move into Formula E and exit from the German Touring Car Championships (DTM). The company will of course continue to run its successful F1 team in its chase for a fourth consecutive constructor’s title.

At the end of last year, Audi pulled out of the WEC racing series, of which Le Mans is an integral part, to focus on Formula E. With both Audi and Porsche gone from Le Mans racing, Toyota will now be seriously weighing its options in this prototype form of motor sport, especially after its CEO, Akio Toyoda recently announced that his company would return to Le Mans next year.
