Mahindra Blueprints: Cooling

How does cooling in a Formula E race car work? In Episode 3 of Mahindra Blueprints,
we dive into the details.

THE M4ELECTRO

When electrifying passion meets engineering genius, the M4Electro is the result.

Through the contest #NameTheM4Electro, our race cars were christened ‘Volt,’ ‘Raptor,’ ‘Apex’ and ‘Agni’; and these cars whizzed through some of the most iconic streets in the world.

POWERTRAIN

The all-electric powertrain is also the ‘powerbrain’ of the M4Electro.

Efficiency has been improved by more than 6% and there is mass reduction of 30kg since Season 1 (so ballast needed).

BATTERY

From Season 1 to Season 4, this has been made by Williams Advanced Engineering. This 28 kWh unit houses over 150 Li-Ion cells, supplying 700v to the car.

During the race, teams are permitted to use 28kWh of energy in each car. In Season 4, the maximum outputs are set at 180kW during race mode and 200kW for qualifying, catapulting the car from 0-100kmh in less than three seconds.

Test the best

Our European testing garage is situated near the Circuit de Barcelona. Our engineers put in hours and hours of work to improve the reliability and performance of the M4Electro before every race.

Most prep time, though, is spent on the simulator. The team spends close to 100 hours of simulation for every one hour on the track.

STEERING WHEEL

Formula E cars are getting rapidly more complex and already have hundreds of sensors and many different complex electronics and software systems.

The M4Electro steering wheel is fully configurable by the team: four paddles, ten buttons, five rotaries and six paddles.

REGENERATIVE BRAKING

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.
