An electric powerhouse, the M3Electro carries our in-house developed powertrain for Season 3 of the championship. A revolutionary step ahead from Season 2, it is a manifestation of absolute engineering.
Christened ‘Ampere,’ ‘Voltaire,’ and ‘Arjuna’ (an Indian warrior); these stunners set the streets ablaze. M3Electro was born as a result of 2500 hours of sweat and blood.
The all-electric powertrain is also the ‘powerbrain’ of the M3Electro. A powerful leap from Season 2, it sports more than 300 new components. A six-phase unit with two-speed transmission, it guarantees better performance, reliability and efficiency.
Peak RPM has improved by 14%, while peak torque has increased by 38%. Weighing just 23 kgs, the overall drivetrain mass has reduced by 40% for greater agility.
The M3Electro houses a Williams-developed battery weighing around 350kg, complete with a carbon-fibre safety casing.
During the race, teams are permitted to use 28kWh of energy in each car. In Season 3 the maximum outputs are set at 170kW during race mode and 200kW for qualifying, catapulting the car from 0-100kmh in less than three seconds.
Just around the corner of the famed Circuit de Barcelona lies our European testing garage. This is where our engineers spend hours setting up and fine tuning the M3Electro for the next race.
But the most crucial tool for prep time is the simulator. The team spends close to 100 hours of simulation for every one hour on the track.
Formula E cars are getting rapidly more complex and already have hundreds of sensors and many different complex electronics and software systems.
The M3Electro sports a new and fully customisable steering wheel – with six rear paddles, six rotary controls, ten buttons, LED warning lights and a larger colour LCD dash display.
It’s the most unique feature in electric racing technology. Every time the driver hits the brakes, the car's kinetic energy – that would have otherwise been wasted – is recaptured and converted into electricity. Power is fed back into the batteries, charging them up.
Permitted energy regen increased from 100kW to 150kW in Season 3. However, the maximum power output remains 200 kW.
